subtract the quoient of 8 divided by 7 from 9

B. I did my math

Using google

Answer: The solution of the system of the equation is, (8,-1)

Step-by-step explanation:

Using substitution method

[tex]2x+4y=12[/tex]      .......... (1)

[tex]y=\frac{1}{4}x-3[/tex]      ......... (2)

Now we are putting equation (2) into equation (1), we get the value of 'x'

[tex]2x+4(\frac{1}{4}x-3)=12[/tex]

[tex]2x+\frac{4}{4}x-4\times 3=12[/tex]

[tex]2x-x=12+12[/tex]

[tex]3x=24[/tex]

[tex]x=8[/tex]

Now put the value of 'x' in equation (2), we get the value of 'y'

[tex]y=\frac{1}{4}x-3[/tex]

[tex]y=\frac{1}{4}\times 8-3[/tex]

[tex]y=2-3[/tex]

[tex]y=-1[/tex]

Hence, the correct option is, (8,-1)

The solution to the system of equations is (-1, 8).

The given system of equations is:

2x + 4y = 12

y = ⅓x - 3

To find the solution to the system, we can solve it by substitution or elimination method:

Substitution Method:

Therefore, the solution to the system of equations is (-1, 8).

There are different kind of speed in mathematics like average speed, instantaneous peed, to solve this question we need to know the concept of average speed. Therefore the correct option is option B

Average speed is defined as the total sum of distance divided by total sum of time

Mathematically,

Average speed  = total distance ÷total time taken

Here we have to find the percent of of Celina’s average running speed

So for this we will apply formula as

(Difference in distance ÷original distance)×100

So from question, Celina walk  4 miles in 1 hour  and can run 8 miles in 1 hour so, the the difference in distance between running and walking is 8-4= 4

So to find the percent of Celina’s average running speed is her average walking speed = (4 ÷8)=50%

Therefore, Celina’s average running speed is her average walking speed is 50%. The correct option is Option B

Answer:

D because 5 over 8 is 0.625 when as a decimal and that means that the number terminates because the number does not repeat

Step-by-step explanation:

hopefully i am right and i do not want brainiest give it to the other guy

divide the money he has to spend by the price per jar

18 / 1.14 = 15.79

since he can't buy 0.79 of a jar round your answer down, he can  buy 15 jars

Answer: There is 211 number of acres of barley the farmer can plant and still be under budget.

hgfhfhfghfgh

Step-by-step explanation:

Since we have given that

Amount of budget = $18000

Expenses he spent to plant wheat = $8100

So, Total amount for acre is given by

[tex]\$18000-\$8100\\\\=\$9900[/tex]

Cost of each acre to plant = $47.00

So, the maximum number of acres of barley is given by

[tex]\dfrac{9900}{47}\\\\=210.63\\\\=211\ acres[/tex]

Hence, there is 211 number of acres of barley the farmer can plant and still be under budget.

Tom's new credit card has a $35 annual membership fee due in September

Tom received a credit card bill totaling $45 and was only able to pay the $20 minimum payment before the due date.

How much balance will show up on Tom's credit card in September if the introductory APR of 0% still applies and the late fee is $30?

35+25+30=90

Answer:  The required number is 70.4.

Step-by-step explanation:  We are given to find the number of which 31.68 is 45%.

Let x be the required number.

Then, according to the given information, we have

[tex]45\%\times x=31.68\\\\\Rightarrow \dfrac{45}{100}\times x=31.68\\\\\Rightarrow x=\dfrac{3168}{45}\\\\\Rightarrow x=70.4.[/tex]

Thus, the required number is 70.4.

Answer: 25 miles per hour

Step-by-step explanation: Since elephant run 1/4 miles in 36 sec

that means in 1 sec elephant runs 1/(4×36) miles

and 1 hour=60×60 sec

that means in 1 hour elephant runs (60×60)/(4×36) miles=25 miles

i.e. elephant runs 25 miles per hour

Try using P.E.M.D.A.S,it will make the problem much easier:(make sure you do each step in order.)

P:Parenthesis,solve the equation in the parenthesis first.

E:Exponants,solve the exponants,if they're are none,you can skip this step.

M:Multiplication,Multiply any numbers that need to be multiplied.

D:Division,divide,if there is nothing to divide,you may skip this step.

A:Addition,add and solve for a sum.

S:Subtraction,subtract any numbers that need to be subtracdted.

    If this did not help or seemed confusing,i strongly suggest you look it up on the internet or ask your teacher about P.E.M.D.A.S,it makes problems much easier to solve. :)

To find 1520 divided by 83 with the remainder, divide 1520 by 83, which results in 18 with a remainder of 26.

The question from the student involves dividing 1520 by 83 and finding the remainder. To perform this calculation, we divide 1520 by 83. The quotient is the whole number result of the division, and the remainder is what is left over after the division.

Here's how you'd calculate it:

Divide 1520 by 83.

Find the whole number quotient, which is the number of times 83 goes into 1520 completely.

Calculate the remainder by subtracting the product of the quotient and 83 from 1520.

In this case, 1520 \\div 83 is 18 with a remainder of 14, since 83 x 18 = 1494, and 1520 - 1494 = 26. Therefore, 1520 divided by 83 equals 18 with a remainder of 26.
