Call b the amount of babysitting hours and 5 the amount of gardening hours.
10b+5g=80
b+g=12
Subtract 5 times the second equation from the first to get:
5b=20
Thus, b=4. g=12-4, or 8. Therefore, Sarah spends 4 hours babysitting and the rest gardening.
Answer:
Step-by-step explanation:
If XY bisects DF at point E, then DE = EF.
Given DE = 2y and EF = 8y-3
2y = 8y-3
subtract 8y from both sides
2y-8y = 8y-8y-3
-6y = -3
y = 3/6
y = 1/2
y = 0.5
DF = DE+EF
DF= 2y+8y-3
DF = 10y - 3
DF = 10(0.5)-3
DF = 5-3
DF = 2
