what is the answer to
3(4x+6)+7x

Answers

3(4x + 6) + 7x
12x + 18 + 7x
19x + 18 <==

The simplified value of the given expression 3(4x+6)+7x, is 19x+18

What is an expression?

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Mathematical expressions have only numbers and operators, while algebraic expressions have both numbers and variables in terms, separated by operators in between.

For example, 4m + 5 is an expression where 4m and 5 are the terms and m is the variable of the given expression separated by the arithmetic sign +.

Given that, is an expression 3(4x+6)+7x, we need to simplify it,

3(4x+6)+7x

By the Distributive property, multiplying by 3,

3(4x+6)+7x

= 12x+18+7x

Rearranging the terms,

= 12x+7x+18

Adding the like terms,

= 19x+18

Hence, the simplified value of the given expression 3(4x+6)+7x, is 19x+18

Light travels at 3.0 x 105 km/s. The sun is 1.5 x 108 km from Earth. How long does it take for the sun's light to reach Earth?

Answers

it takes 8 mins and 20 secs for light to travel to earth

Answer:

It takes 8 minutes and 20 seconds for the light to travel this distance

Step-by-step explanation:

Velocity is calculated as:

V= d/t (1)

Where d is distance and t is time. As we want to find time t we must simplify (1) for t

t= d/V (2)

We replacethe values given:

t=d/V=1.5*10^8/3.0*10^5=5*10^3 = 500 seconds

As there are 60 seconds in a minute we find

minutes = 500/60 = 50/6 = 25/3 = 8 2/3 or 8 minutes 20 seconds

In 8 months, 55.6 gallons were used. Find the unit rate.

Answers

6.95 gallons in 1 month

Answer:

6.95 gallons/month

Step-by-step explanation:

We are given that In 8 months, 55.6 gallons were used

Amount used in 8 months = 55.6 gallons

We are supposed to find amount used per month i.e. unit rate

So, Amount used in 8 months = 55.6 gallons

Amount used in 1 month = [tex]\frac{55.6}{8}[/tex] gallons

Amount used in 1 month = [tex]6.95[/tex] gallons

So, 6.95 gallons were used in 1 month

Hence the unit rate is 6.95 gallons/month

Greg builds a new pond which has a volume of 7.35 m3. It is 4.2 m long and 50 cm deep. What is the width of the pond?

Answers

volume = length x width x depth

50cm = 0.5 m

7.35 = 4.2 x 0.5 x X

7.35 = 2.1 x X

x = 7.35 / 2.1

x = 3.5

width = 3.5 meters

Answer: 3.5 meters

Step-by-step explanation:

Given : The volume of a new pond = [tex]7.35\ m^3[/tex]

The length of a new pond = 4.2 m

The depth of the pond = 50 cm =0.5 m

Let the width of the pond be 'w'.

The volume of cuboid is given by :_

[tex]V=l\times h\times w\\\\\Rightarrow\ 7.35=4.2\times0.5\times w\\\\\Rightarrow\ w=\dfrac{7.35}{0.5\times4.2}\Rightarrow\ w=3.5[/tex]

Hence, the width of the pond = 3.5 meters

what is 10/4 as a mixed number

Answers

We have 4 parts in one whole when we split it into fourths; in other words, 4/4 = 1 whole. To convert 10/4 to a mixed number, we first need to find out how many wholes can fit into it. In this case, we can break 10/4 down into

[tex] \frac{4}{4}+ \frac{4}{4}+ \frac{2}{4} [/tex]

Giving us 2 wholes and 2 fourths, or 2 2/4 as a mixed number. Note that 2/4 is the same as 1/2, so we can write the simplified mixed number as 2 1/2

The fraction 10/4 written as a mixed number is 2 1/2

Given the improper fraction :

10/4

To convert to a mixed number ; divide Numerator by denominator and express the remainder as a fraction

10/4 = 2 2/4

Express in its simplest form:

2 2/4 = 2 1/2

Hence, the mixed number value is 2 1/2

2. Which conjecture is true?

A. An even number plus 3 is always even.
B. An even number plus 3 is always prime.
C. An even number plus 3 is always odd.
D. A prime number plus 3 is always even

Answers

The answer is C. A way to find out is to add a few numbers from that group being specified. If you add 2 or even 100 to 3, the answer will be odd. If you add 12 to 3, you will get 15 which is a composite number. If you were to add 2 to 3, you will get 5 which is an odd number.

C. An even number plus 3 is always odd.

Prime number: A number that can only be divided by 1 and itself. For example 7, 11, etc

Odd number: Any number that cannot be divided by 2. For example 3, 5, 7, etc

Even number: Any number than can be divided by 2. For example: 4, 6, 8, etc

If we add 2,4,6 or 1000 to 3, the resultant will be always odd. If we add 2 to 3, we will get 5 which is an odd number. If we add 8 to 3, you will get 11 which is an odd number.

So, the conjecture is :

An even number plus 3 is always odd.

Therefore the correct option is (c).

the table shows the prices for different party toy packages from the Tomtown Toy Company.Which item costs the least per toy? Explain your reasoning

Answers

Answer:

Dominoes costs the least per toy.

Step-by-step explanation:

From the given table it is clear that

Cost of 6-pack of Dominoes = $3.98

Cost of 1-pack of Dominoes = [tex]\frac{\$3.98}{6}\approx \$0.663[/tex]

The cost of 1-pack of Dominoes is $0.663.

Cost of 12-pack of Peg Games = $9.99

Cost of 1-pack of Peg Games = [tex]\frac{\$9.99}{12}=\$0.8325[/tex]

The cost of 1-pack of Peg Games is $0.8325.

Cost of 24-pack of Mini Footballs = $17.98

Cost of 1-pack of Mini Footballs = [tex]\frac{\$17.98}{24}\approx $0.75[/tex]

The cost of 1-pack of Mini Footballs is $0.75.

$0.663 is less than $0.8325 and $0.75. It means dominoes costs the least per toy.

Hamburger costs $1.50 per pound and soy costs $1.00 per pound. The school cafeteria uses 50 more pounds of soy than hamburger and spends $350 a week. How much soy does the school use?

Answers

Suppose the the school uses x pounds of Hamburger, then the number of pounds of soy is x+50, the cost of Hamburger is 1.50x, the cost of soy is 1.00(x+50), the total cost if 350
1.50x +1.00(x+50)=350
2.50x+50=350
2.50x=300
x=120
120+50=170
so the school uses 120 pounds of Hamburger and 170 pounds of soy

Prove that ax+by+c=0 represent the eqn of straight line

Answers

If we rewrite it as y=mx+d (which can be taken from here from subtracting ax and c from both sides, then dividing b, resulting in y=(-a/b)(x)-c/b. We can then substitute -a/b for m and -c/b for d), if d=0, then we have m as a constant and as we add a specific number to y (that number being m) every time the x value increases by 1, it therefore forms a straight line. If d is not 0, then we simply add d to every single number - this is still a straight line due to that we still add a specific number to y every time x increases by 1 every single time

Which is the best estimate of 28 × 0 . 64 28×0.64?

A. 10
B. 15
C. 21
D. 28

Answers

Answer:

It is 15.

Step-by-step explanation:

Because the actual answer between 28 x 0.64 is 17.92.

Final answer:

The closest estimate for the multiplication of 28 by 0.64, is approximately 19 and given the options, 15 would be the best choice.

Explanation:

The question is asking for the closest estimate for a multiplication problem, 28 times 0.64. We can convert the decimal 0.64 to a fraction which is approximately 2/3 (as 0.67 is closer to 0.64 than 0.5 - which would be 1/2). Hence, when multiplying 28 by 2/3, we get approximately 19.

Looking at the options given, 19 is not there. So, we select the nearest option to 19 which, in this case, it would be option B. 15.

Step-by-step explanation:

We need to find out the [tex](goh)(9)[/tex]

Given:- [tex]g(x)=2x-1[/tex] and [tex]h(x)=\sqrt{x}[/tex]

First we need to find out the composition of (gof)(x)

Replace x in function g(x) with h(x) as;

[tex](goh)(x)=2(h(x))-1[/tex]

[tex](goh)(x)=2(\sqrt{x})-1[/tex]

Now put x=9 , in above to get the [tex](goh)(9)[/tex]

[tex](goh)(9)=2(\sqrt{9})-1[/tex]

[tex](goh)(9)=2(3)-1[/tex]

[tex](goh)(9)=6-1[/tex]

One-third of the dairy cattle on a farm are in the barn. Three-fifths of the beef cattle are in the barn. There are 30 dairy cattle and 15 beef cattle in the barn. How many more dairy cattle are on the farm than beef cattle?

Answers

There are 50 more dairy cattle than beef cattle.

Given that 30 = 1/3rd of the total Dairy Cattle that means there are 2 more sets of 30 elsewhere. 30 x 3 = 90 Dairy Cattle total.

If 15 is 3/5ths of the beef cattle then that means that 1/5th is 5 (Since 15 divided by 3 = 5). This means that in total (Since 1/5th is 5) you can multiply 5 by 5 to get 25 Beef Cattle total.

Overall 90 - 25 = 65 more Dairy Cattle total
