Should be -200 if I'm correct.
Step-by-step explanation:
Answer:
CN Tower = 550 m and church tower = 160 m
Step-by-step explanation:
The first equation x + y = 710 is correct
but the second one is
x - y = 390
Note x = height of the CN tower and y = height of the church.
x + y = 710
x - y = 390
If we add the 2 above equations we eliminate y so
2x = 1100
x = 550 m
and y = 710 - 550 = 160 m
Answer:
b
Step-by-step explanation:
its on the half
Replace p in the given equation with the price of the item:
23 -0.15(23)
Simplify:
23 - 3.45 = 19.55
answer: $19.55
Answer:
B) 47
Step-by-step explanation:
If we assume the 2.5P is more accurately 2.54P, then we have two relations between N and P:
Solving the second for P gives ...
P = N -10
and substituting that into the first gives ...
2.54(N -10) = 2N
0.54N -25.4 = 0 . . . . . . subtract 2N
N -47.037... = 0 . . . . . . .divide by 0.54
N ≈ 47 . . . . . . . . . . . . . . add 47.037... and round
The closest value of N is 47.

<em>Comment on the problem</em>
If you take the problem at face value, you compute N=50. The closest offered answer is still 47. In this scenario, the relationship between inches and centimeters is irrelevant, as there are no inches anywhere in the problem.
