Answer: c. 66
Step-by-step explanation:
Add 76 and 38.
76+38 = 114
Take 180 minus 114
180-114 = 66
Answer:
a=30 , b = 0
Step-by-step explanation:
let the two numbers be represented as a and b
a + b = 30... eqn 1
a - b = 30 ...... eqn 2
we then add the two equations to get values for a and b
a + b + a - b = 30 + 30
a + b + a -b = 60
2a = 60 ( diivide both sides by 2)
a = 30
we then put value for a = 30 into any of the equations to get b
a + b = 30, 30 + b= 30
b = 30 -30 , b = 0
to confirm if the answers are correct, we insert the values for a and b in the two equations.
a + b = 30..... eqn 1, 30 + 0 = 30
a - b = 30 ...... eqn 2 , 30 - 0 = 30
The answer would be 0.5 miles per hour. This is because to get from feet per hour to Miles per hour, you need to divide by 5280. (1 mile = 5,280 feet.)
