You have to do the integers first. 5 to the 7th power is 78,125. 5 to the 3rd power is 75. Now you have to divide 78,125 by 5. It would be 15,625. Now you have to multiply 15,625 by 75 to get 1,171,865.

$\large\boxed{B)\ -2}$

Step-by-step explanation:

$\left\{\begin{array}{ccc}3(x+y)=12&(1)\\\\\dfrac{x}{2}=3&(2)\end{array}\right\\\\(2)\ \dfrac{x}{2}=3\qquad\text{multiply both sides by 2}\\\\2\!\!\!\!\diagup^1\cdot\dfrac{x}{2\!\!\!\!\diagup_1}=(2)(3)\\\\x=6\\\\\text{Put it to (1):}\\\\3(6+y)=12\qquad\text{divide both sides by 3}\\\\\dfrac{3\!\!\!\!\diagup^1(6+y)}{3\!\!\!\!\diagup_1}=\dfrac{12}{3}\\\\6+y=4\qquad\text{subtract 6 from both sides}\\\\6-6+y=4-6\\\\y=-2$

Solve for A if F=MA and F=10 and M=2.5

gogolik [260]

Answer:

$\boxed{\sf A = 4}$

Given:

F = MA

F = 10

M = 2.5

To Find:

Value of A

Step-by-step explanation:

$\sf Substituting \ values \ of \ F \ and \ M \ in \ F = MA:$

$\sf \implies 10 = 2.5A$

$\sf \implies 2.5A = 10$

$\sf Dividing \ both \ side \ of \ 2.5A = 10 \ by \ 2.5:$

$\sf \implies \frac{2.5}{2.5} A = \frac{10}{2.5}$

$\sf \frac{2.5}{2.5} = 1 :$

$\sf \implies A = \frac{10}{2.5}$

$\sf \frac{4 \times \cancel{2.5}}{ \cancel{2.5}} = 4 :$

$\sf \implies A = 4$
