Answer:
y = 40
Step-by-step explanation:
The sum of the angles of a triangle are 180 degrees
y+10 + 2y +50 = 180
3y+60 = 180
Subtract 60 from each side
3y+60-60 = 180-60
3y = 120
Divide each side by 3
3y/3 = 120/3
y = 40
Answer:
no because r is a varible that dont have number
You answer should be B because you would flip the fraction so the powers would become positive and then take 3 from 5 to be left with 8^2 on the bottom with one on the top.
Answer:
Last option is the correct choice.
Step-by-step explanation:
Convert the mixed numbers into fraction and apply the rate formula.
Rate = Change / Unit Time
= 12 1/4 ÷ 3 1/2
= 49/4 ÷ 7/2 (Answer matching with the last option)
= 49/4 x 2/7 (Inverting the second fraction)
= 7/2
= 3 1/2
The rate of change per hour is 3 and a half degrees in temperature.

The answer is 32 8 times 4 would equal 32
