Answer: (4,-5)
Step-by-step explanation:
8y = -40
(divide by 8)
y = -5
(plug it in to one of the equations)
3x + 6*-5 = -18
3x + -30 = -18
3x = 12
x = 4
Answer:
85 degrees
Step-by-step explanation:
its really easy just make them equal to eachother and then solve
9x + 13 = 11x-3
-11x (subtract because 11x is positive)
-2x +13 = -3
-13 (subtract because 13 is positive)
-2x = -16
divide both sides by -2
x= 8
substitute 8 for the x's and you have your answer
Answer:
$48
Step-by-step explanation:
To figure out how much the game costs in total, we first need to divide $36 by 3 (3 is the numerator).
36 / 3 = 12
The number 12 is how much each quarter is worth as shown below.
1/4 = 12
2/4 = 24
3/4 = 36
4/4 = ?
To find the answer, all we do is add 12 to 36.
12 + 36 = $48
