2x+8=7x-12 || -m/4+5=2 || 3x-8=-17 ||

1 answer:

3 0

2x+8=7x-12 we put the x in a side and the number in the other side
5x = 20
x= 20/5 = 4

 -m/4+5=2
 common denominator
-m /4 + 20/4 = 2/4
-m +20 = 2

m = 20-2 =18

3x-8=-17

3x = -17 +8

3x = -9

x= -9/3 = -3

D -e/3d + e= e, for d

navik [9.2K]

Answer:

$\large\boxed{d=\dfrac{e^2+e}{1-3e}}$

Step-by-step explanation:

$\dfrac{d-e}{3d+e}=e\\\\\dfrac{d-e}{3d+e}=\dfrac{e}{1}\qquad\text{cross multiply}\\\\(1)(d-e)=(e)(3d+e)\qquad\text{use the distributive property}\\\\d-e=3de+e^2\qquad\text{add}\ e\ \text{to both sides}\\\\d=3de+e+e^2\qquad\text{subtract}\ 3de\ \text{from both sides}\\\\d-3de=e^2+e\qquad\text{distribute}\\\\d(1-3e)=e^2+e\qquad\text{divide both sides by}\ (1-3e)\\\\d=\dfrac{e^2+e}{1-3e}$

Rearrange the equation so q is the independent variable. 9q-4=3r-6 r = __

erik [133]

Answer:r=3q+2/3

Step-by-step explanation:

Step 1: Flip the equation.

3r-6=9q-4

Step 2: Add 6 to both sides.

3r-6+6=9q-4+6

3r=9q+2

Step 3: Divide both sides by 3.

3r/3=9q+2/3

r=3q+2/3

Hopefully it’s right

I need help again please help me with this question

Anestetic [448]

Answer:

The size of a sundae and the amount of calories it contains.

Step-by-step explanation:

The answer choice is the only one with a positive correlation, because it is the only one that isn't depleting or going down in size. No matter if you eat the sundae or what size it becomes, the calories it contains will still be the same for the whole amount.

When a car travels, gas is used and it depletes. As a snowball does when it melts. And "the temperature on Tuesday" has no correlation involved at all
