Answer:
LESLEY GETS ABSOLUTELY NOTHINGGGG
Step-by-step explanation:
1) = 7 (to the power of 4)
2) = b (to the power of 2)
3) = 3 (to the power of 5)
4) = -2 (to the power of 5)
Let x be the amount of hours the plumber worked.
Therefore, we get:
40x+65=325
Solve for x.
40x=260
x=6.5
Therefore, the plumber worked for 6.5 hours.
R-9s=2 add 9s to both sides
r=2+9s making 3r-3s=-10 become:
3(2+9s)-3s=-10 perform indicated multiplication on left side
6+27s-3s=-10 combine like terms on left side
6+24s=-10 subtract 6 from both sides
24s=-16 divide both sides by 24
s=-16/24
s=-2/3, making r-9s=2 become:
r-9(-2/3)=2 perform indicated multiplication on left side
r+6=2 subtract 6 from both sides
r=-4
So s= -2/3 and r= -4
