Answer:

−30a−6

Step-by-step explanation:

Let's simplify step-by-step.

−9a−10−6a+7−9a−10−6a+7

=−9a+−10+−6a+7+−9a+−10+−6a+7

Combine Like Terms:

=−9a+−10+−6a+7+−9a+−10+−6a+7

=(−9a+−6a+−9a+−6a)+(−10+7+−10+7)

=−30a+−6

Find the value of x and the measure of each angle in the parallelogram

Morgarella [4.7K]

Answer:

$\angle D= 162\\\\\angle E = 18\\\\\angle F = 162\\\\\angle G = 18$

Step-by-step explanation:

By properties of parallelograms we know that opposite are the same so we have

$12x=4(x+3)\\\\4(3x)=4(x+3)\\\\3x=x+3\\\\2x=3\\\\x=\frac{3}{2}$

so for the angles we have

$\angle G=\angle E=12(\frac{3}{2})=18\\\\\angle D=\angle F = 180-\angle G=180-18=162$

F(x) = 3x - 2<br><br> f(x) = 0, x=?

podryga [215]

Answer:

2/3 =x

Step-by-step explanation:

f(x) = 3x - 2

Let f(x) =0

0 = 3x-2

Add 2 to each side

2 = 3x-2+2

2 =3x

Divide by 3

2/3 =3x/3

2/3 =x

What is the first step needed to solve 2 over 5 multiplied by x minus 6 equals negative 16 ? (1 point) Subtract 16 from both sid

AfilCa [17]

Answer:

The first step is Add 6 to both sides

Step-by-step explanation:

we have

$\frac{2}{5}x-6=-16$

Solve for x

That means ----> isolate the variable x

step 1

Adds 6 both sides

$\frac{2}{5}x-6+6=-16+6$

$\frac{2}{5}x=-10$

step 2

Multiply by 5/2 both sides

$\frac{2}{5}x(\frac{5}{2})=-10(\frac{5}{2})$

$x=-25$

therefore

The first step is Add 6 to both sides
