1 decimeter is 10 centimeter so you divide 27 by 10 and get 2.7
So she cut 2.7 decimeter off her hair
2/3 x + 1 = 27
subtract 1 from each side
2/3 x = 26
multiply by 3/2
3/2 * 2/3 x = 26 * 3/2
x = 39
A. it takes the robot 36 minutes to complete one task.
b. the robot can do one task and a half in one hour.
Answer:
x=23,y=15
Step-by-step explanation:
take away 8 from 38, divide it by 2, you get 15. add 8 to one of the set of two 15s. you get 23 and 15
The equation is for when you compound annually is

A=future amount
P=initial amount or principal
r=interest rate in decimal form
t=time in years
so
A=A
P=3500
r=7.5%=0.075
t=13


use your calculator
A=8961.4457
round to nearest dollar
A=$8961
that's how much the investment will be worth after 13 years
