The remainder is 21...........
Answer:
A. 8
Step-by-step explanation:
16+y=24
16+8=24
Therfore the answer is A
x<-3,or x>3
only A and B satisfy the given condition.
Answer:
y = 7/5x + 4
Step-by-step explanation:
use the slope from the equation -5/7 and take the negative reciprocal to get the perpendicular slope = 7/5. Then use the equation y=mx+b. Plug in x and y from the point given and the new slope and solve for b.
(-3) = (7/5)(-5) + b, (-3) = -7 + b, add 7 to both sides. b = 4. Rewrite the equation now to be y = 7/5x + 4
She worked 2 1/2 hrs yesterday and 4 1/4 hrs today...
2 1/2 + 4 1/4 =
2 + 4 = 6
1/2 + 1/4 = 2/4 + 1/4 = 3/4
so she worked a total of 6 3/4 hrs....or 6.75 hrs
she is paid $ 54
54 / 6.75 = $ 8 per hr <=== what she earned per hr
