Answer:

Aaron still needs to save $9

Step-by-step explanation:

Assuming the equation is 8a + 56 = 128

8a + 56 = 128

8a = 128 - 56 = 72

8a = 72

a = 72/8 = $9

Help me solve this please -22-x=5+6x+9
ollegr [7]

Answer: x = -5  1/7

Step-by-step explanation:

-22 - x = 5 + 6x + 9

First, combine the like terms 5 and 9

5 + 9 = 14

-22 - x = 14 + 6x

Add x to each side

-22 = 14 + 7x

Subtract 14 from each side

-36 = 7x

Divide each side by 7

x = -5 1/7 (Yes, a fraction.)

Please help asap with this question i will give brainliest.
HACTEHA [7]

Answer:

D

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k) = ( - \frac{1}{5}, \frac{1}{3} ) and r = \frac{1}{2}, thus

(x - (- \frac{1}{5} ))² + (y - \frac{1}{3} )² = ( \frac{1}{2} )², that is

(x + \frac{1}{5} )² + (y - \frac{1}{3} )² = \frac{1}{4} → D

The sum of the measure of the interior angles of a polygon is 1980°. What polygon is it? 10-gon 11-gon 12-gon 13-gon
tiny-mole [99]

Answer:

13-gon

Step-by-step explanation:

The sum of the interior angles of a polygon with n sides is:

S = 180° (n − 2)

If S = 1980°, then:

1980° = 180° (n − 2)

11 = n − 2

n = 13
