Answer:
Let's say that x is sam's age and y is Amy's age
x=y-4
and five years ago:
x-5=(y-5)/2
y-4-5=(y-5)/2
2y-18=y-5
y=13
x=9
then:
sam's age is 9 and Amy's age is 13
Answer:
1
Step-by-step explanation:
To solve this, first, take 22 minutes and divide it by 60 minutes, which is the number of minutes in an hour. Then, add two to the value, and multiply it by six square meters per hour, which is the rate that David can paint the wall. From there, you get 14.2 square meters which he painted in 2 hours and 22 minutes. Divide 14.2 square meters by the length of 11 meters to get 1.290 meters. Since they asked you to round to the nearest meter, you get 1 meter.
Answer:
c; 1 / (a^12)(b^8)
Step-by-step explanation:
when the exponent is outside a number you multiply the outside exponent by the inside exponent
so far after multiplying exponents you have
a^-12 / b^8
but you must put the 12 on the bottom so that all exponents can be positive
1 / (a^12)(b^8)
