Answer:
10
Step-by-step explanation:
2(6+1) - |-10| + 3*2
= 2 (7) - (+10) + 6
= 14 - 10 + 6
= 20 - 10
= 10
I hope this helps you
12/12+x=13/13+26
12/12+x=13/39
12/12+x=1/3
12+x=36
x=24
I think the set would be (4,16) Don't count my answer though that's an educated guess... XD
Answer:5.6089*10^4
Step-by-step explanation:
Answer:
The first rate was 120
The second rate was 85
Step-by-step explanation:
r1 = x
r2 = y
10*x + 15*y = 2650
x + y = 205 Multiply this equation by 10
10x + 10y = 2050 Subtract this equation from the top equation.
10x + 15y = 2650
10x + 10y = 2050
5y = 600
y = 600/5
y = 120
x + y = 205
x + 120 = 205
x = 205 - 120
x = 85
