Answer: 26 years old
Step-by-step explanation:
Since Scott is four more than double the age of Todd, start by taking away four from Scott's age.
56-4=52
Then take half of that because that would be double of Todd's age
52/2=26
Todd is 26 years old.

Answer:
cost = 56 + 8t, where t is the number of hours worked for.
for 4 hours of work, cost = 56 + 8 x 4 = $88
Step-by-step explanation:
Answer:
Step-by-step explanation:
EF - base1
HG - base2
J-midpoint of EH
K-midpoint of FG
We are solving it by using formula:
JK=(base1+base2):2
25=(3x+2+7x-2):2
25*2=10x
50=10x
x=50:10
x=5
Good luck!
