3a-9=8a+6

3a-9-6=8a+6-6

3a-15=8a

3a-3a-15=8a-3a

What is the value of (3-5)*(2) — 16- 2?<br> -40<br> 0 -16<br> ооо<br> 24<br> 56
valina [46]

if i didn't understand it wrong, * is (3-5) x (2)

so,

(3-5)x 2-16-2

=-2x2-16-2

=-4-16-2

= -22

But if * means (3-5)^2 -16-2

then its,

(3-5)^2-16-2

=(-2)^2 -18

=4-18

= - 14

But looks like both of them are not in your choice at all

Cody is baking a square cake for his friend's wedding. When served to the guests, the cake will be cut into square pieces 1 inch
Maru [420]
Because each guest gets a 1square inch piece the cake needs to be 121 square inches.  Because it is a square cake we need to figure out what times itself equals 121 and the best way to do that is to find the square root of 121 which is 11

each side should be 11 inches

I hope I've helped!

What would you do to solve the system?
kipiarov [429]
Answer:

Explanation:

12x = 48 - 8y
10x + 8y = 38
———————
12x + 8y = 48
10x + 8y = 38
———————
12x + 8y = 48
-1(10x + 8y = 38)
————————
12x + 8y = 48
-10x - 8y = -38
————————
2x = 10
x = 10/2 = 5

If x = 5 then:
10x + 8y = 38
10(5) + 8y = 38
50 + 8y = 38
8y = 38 - 50
8y = -12
y = -12/8
y = -3/2

Therefore, x = 5 and y = -3/2
