Answer:
D) she can divide 7 by 2
Step-by-step explanation:
As, Division is not same as multiplication, so not the a option
And b doesn't have the right values
C is also wrong bc it have multiplication
So D is right

↝ f(4) equals to substituting x = 4 in the equation.
Thus,

Therefore, f(4) = 2
Answer:
16 is the width 32 is the length
Step-by-step explanation:
L = 2x
96 = 2L + 2x Substitute the first equation into the second equation for L
96 = 2(2x) + 2x Multiply
96 = 4x + 2x Add
96 = 6x Divide both sides by 6
16 = x
Plug this into the first equation to solve for the length
L = 2(16) Multiply
L = 32
The answer will be 10 as the ratio is 4. 10 x 4 = 40
This can be written as 3(n+12)=45, where n is the unknown number
3(n+12)=45 <- Starting Equation
3n+36=45 <- Distributive Property
3n=9 <- Cancel 36 on both sides
n=3 <- Divide both sides by 3
So n=3
Hope this helped!
