Answer:
See below.
Step-by-step explanation:
1. 3 * 15 + 4 * 15 - 5 * 15
45 + 60 - 75
105 - 75
30
2. 3x + 4x - 5x
7x - 5x
2x
3. 3(x-2) + 4(x-2) - 5(x-2)
3x - 6 + 4x - 8 - 5x + 10
2x - 4
4. (I'm not typing that out)
7.5x + 19.5 + 10x + 26 - 12.5x - 32.5
5x+13
-hope it helps
Answer:
I sure hope none is an answer because none of these work!
Step-by-step explanation:
C = 59 (F - 32)
(C/59) = F - 32
F = C/59 + 32
So no :(
m = x + y + z3
y = m - x - z3
So no :((
s = r^2 - 1
r = sqrt(s+1)
So no :000
A = 12(a+b)
A = 12a + 12b
12b = A - 12a
b = A/12 - a
So no :00(((
m = x + y^2
y = sqrt (m-x)
AND no :|
