Answer 1

10) 6(x + 3) = 21
6x + 18 = 21
6x + 18 -18 = 21 - 18
6x = 3
6x/6 = 3/6
x = 1/2

6) w- 4/9 = (-4/5) / (3/2)
w - 4/9 = -4/5 x 2/3
w - 4/9 = -12/15
w - 20/45 = -36/45
w = 20/45 - 36/45
w = -16/45

the second of three numbers is 1 less than the first. The third number is 5 less than twice the second. If the number exceeds the first number by 12, find the three numbers

Answers

The three numbers are found by forming and solving a system of equations: the first number is 19, the second is 18 (which is one less than the first), and the third is 31 (which is 5 less than twice the second and exceeds the first by 12).

To solve the problem of finding the three numbers, we can set up a system of equations based on the information given:

The first number is x.The second number is one less than the first, so it is x - 1.The third number is 5 less than twice the second, which translates to 2(x - 1) - 5.The third number also exceeds the first by 12, so 2(x - 1) - 5 = x + 12.

Now we can solve for x:

2(x - 1) - 5 = x + 122x - 2 - 5 = x + 122x - x = 12 + 2 + 5x = 19

The first number is 19. The second number is 18 (19 - 1), and the third number is 31 (2(18) - 5).

Thus, the three numbers are 19, 18, and 31.

How many 1/4 ft pieces can you cut from a string that is 15 feet long

Answers

there is 4 pieces in a ft and 4 × 15 is 60
so the answer is 60 pieces

Final answer:

You can cut 60 pieces of 1/4 foot each from a string that is 15 feet long by carrying out the operation 15 ÷ 1/4, which turns into multiplication by the reciprocal of the fraction, 15 x 4 equals 60.

Explanation:

The question is asking how many 1/4 ft pieces you can cut from a 15 feet long string. In other words, you want to divide the total length of the string by the length of each piece you're cutting out. So you will carry out a division operation: 15 ÷ 1/4. When dividing by a fraction, you actually multiply by its reciprocal. The reciprocal of 1/4 is 4, so 15 ÷ 1/4 becomes 15 × 4, which equals 60. Therefore, you can cut 60 pieces of 1/4 foot each from a string that's 15 feet long.

Answers

A 7/1 and for B turn minutes into seconds. 10 min * 60 = 600 seconds and now 7 times 600 seconds = 4200 feet

The submarine's elevation after 10 minutes is 4200 feet if the Navy submarine descended from sea level at a rate of seven feet per second.

What is a fraction?

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

It is given that:

A Navy submarine descended from sea level at a rate of seven feet per second writing the descendent rate as an integer.

The rate of drop is 7 feet per second. 7 x 10(60), or 7 x 600, would be the subs elevation.

Consequently, the sub's elevation would be 4,200 feet below sea level.

Thus, the submarine's elevation after 10 minutes is 4200 feet if the Navy submarine descended from sea level at a rate of seven feet per second.

Is the expression a12 a4 equivalent to a8 a8?

Answers

Final answer:

The expressions a12 a4 and a8 a8 are equivalent because according to the laws of exponents, when multiplying terms with the same base, you add their exponents, resulting in both expressions equating to a16.

Explanation:

The question refers to whether the expressions a12 a4 and a8 a8 are equivalent. These expressions are using the laws of exponents, specifically, the rule which states that when you are multiplying terms with the same base, in this case, a, you add their exponents. Therefore, a12 a4 would actually equal a16 because 12 + 4 equals 16. Similarly, a8 a8 would equal a16 because 8 + 8 equals 16, so yes, these expressions are equivalent as they both simplify to a16.

Pauline spent $7.50 every day for 3 days. Which expression is the best choice to help her determine the total amount of money she spent?

(7.50)(−3) = −22.50; she spent $22.50
(−7.50)(3) = −22.50; she spent $22.50
(−7.50)(−3) = 22.50; she spent $22.50
(7.50)(3) = 22.50; she spent $22.50

Answers

Last one. 7.50(3)= 22.50

Answer:

The correct option is 2.

Step-by-step explanation:

It is given that Pauline spent $7.50 every day for 3 days.

Amount spent on each day = $7.50

Number of days = 3

Spent amount and expenditure are always negative.

Total amount of money she spent is

[tex]Total =(-7.50)(3)[/tex]

On simplification we get

[tex]Total =-22.50[/tex]

She spent $22.50 and required expression is (−7.50)(3) = −22.50. Therefore the correct option is 2.

I’m pretty positive you divide 216 by 4, since that’s the amount of sides a box normally has. The answer would be 54 cubic centimeters. Please let me know if I’m correct, hopefully this helped.

Answer:

side of the cubic box is 6 cm

Step-by-step explanation:

The volume of a box for earrings is 216 cubic centimeters.

Volume of a cubic box is [tex](side)^3[/tex]

[tex]Volume = a^3[/tex], where 'a' is the side of the cubic box

[tex]216 = a^3[/tex]

Take cube root on both sides

[tex]\sqrt[3]{216} =\sqrt[3]{a^3}[/tex]

Cube and cube root will get cancelled

So 6=a

Thank You! I got 100 because of this! It is 1/6! :D YES! I love brainly!

The answer is 1/6 after using the number line if the number expression is −1/3 − (−1/2).

What is a number line?

It is defined as the representation of the numbers on a straight line that goes infinitely on both sides.

It is given that:

The fraction numbers are 1/3 and -1/2

As we know,

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

The number expression is:

−1/3 − (−1/2)

From the number line:

Drawing line segment length of 1/3 left side

Drawing line segment length of 1/2 left side

Taking difference using number line:

= 1/6

Also, the arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

= −1/3 − (−1/2)

= -1/3 + 1/2
