Answer:
The mechanic who worked 5 hours charged $115 per hour, the one who worked 15 hours charged $120 per hour.
Step-by-step explanation:
x = rate of mechanic who worked 5 hours
y = rate of mechanic who worked 15 hours
Then
x + y = 235
5x + 15y = 2375
Just solve these 2 equations above for x and y.
x + y = 235 ⇒ x = 235 - y
Substitute into second equation to find y.
5(235 - y) + 15y = 2375
1175 - 5y + 15y = 2375
10y = 1200
y = 1200/10 = 120
x = 235 - y = 235 - 120 = 115
Answer:
12
Step-by-step explanation:
Put in 3 for x and 3 for y:
3(3 + 3 - 2)
3(4)

Answer:
I GOT YOU GIRLLL!!
= D. 10.4cm
Step-by-step explanation:
a^2+ b^2=c2
3^2+10^2=c2
9+100=c2
109=c2
= 
10.4=c
Answer:
Step-by-step explanation:
25m - 100 = 450
25m = 450 + 100
25m = 550
m = 550/25
m = 22 <==== 22 months
