Answers

Answer:

4 4/7

Step-by-step explanation:

You multiply the n by 7 first because you are cross multiplying. So it would be 7n = 32.

So to simplify you would divide 32 by 7 to get n= 4 4/7

4 4/7 is a mixed number 4 is the whole and 4/7 is the fraction just to clarify

Or as a fraction it would be 32/7

The product of Vidya's savings and 9 is 126.

What is the solution of 5/2x-7=3/4x+14

A. X=-6
B. X=6
C. X=8
D. X=12

Answers

Answer x=12

Step-by-step explanation:

5/2x-7=3/4x+14

      +7.         +7

5/2x=3/4x+21

-3/4x -3/4x

5/2-3/4=7/4x

7/4x=21.         since there's a fraction on one side, multiply 4 with 21

7x=84

divide and you'll get x=12

ExplanationGet rid of the denominator by multiplying the whole equation by 4.

[tex] \frac{5}{2} x(4) - 7(4) = \frac{3}{4} x(4) + 14(4) \\ 10x - 28 = 3x + 56[/tex]

Solve the equation for x-term.

[tex]10x - 3x = 56 + 28 \\ 7x = 84 \\ x = \frac{84}{7} \\ x = 12[/tex]

Answers

Answer:

t = 5

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3(t+1)=18

(3)(t)+(3)(1)=18(Distribute)

3t+3=18

Step 2: Subtract 3 from both sides.

3t+3−3=18−3

3t=15

Step 3: Divide both sides by 3.

3t/3 = 15/3

5
1 over 5
negative 1 over 5
−5

Answers

Answer:

The slope is 5

Step-by-step explanation:

divide the change in y by the change in y

you can use two different points for example 1,5 and 3,15

the change in y between these points is 10, the change in x is 2

10/2=5

also since the values of x increase constantly by 1 and it's a continuous line (meaning the domain could be any number between 1 and 3 in this graph) you can calculate only the change in y and that will give you the slope
