Answer:
D
Step-by-step explanation:
10* 8 = 80
15-10=5
8-6=2
5*2= 10
10/2= 5
80+5=85
The answer is The liquid must be in the cooler fewer than 10 minutes. This is because 3 × 10 is 30 and so it would lose 30° after 10 minutes, which makes it 60°, so if the liquid is in the cooler longer than 10 minutes then the temperature becomes less than 60°.

Answer: C. (-4, -2)
<u>Step-by-step explanation:</u>
First, eliminate one of the variables and solve for the remaining variable:
2x - 5y = 2 → 3(2x - 5y = 2) → 6x - 15y = 6
3x + 2y = -16 → -2(3x + 2y = -16) → <u> -6x - 4y = 32</u>
-19y = 38
y = -2
Next, replace "y" with -2 into either of the original equations to solve for x:
2x - 5y = 2
2x - 5(-2) = 2
2x + 10 = 2
2x = -8
x = -4
x = -4, y = -2
<u>Check:</u>
Plug in the x- and y-values into the other original equation:
3x + 2y = -16
3(-4) + 2(-2) = -16
-12 + -4 = -16
-16 = -16
Answer:
250cm
Step-by-step explanation:
60cm+80cm+110cm= 250cm
110 cm comes from 100cm in one meter combined with the other 10cm
