Answer: x=7
ab=21
bc=14
Step-by-step explanation:
ab=3x
bc=2x±7
ac=42
3x±2x±7=42
5x±7=42
5x=42-7
5x=35
to get the value of x you divide 35 by 5x
35÷5x=7
so the value of x is 7
ab=3x
x=7
3x=7×3x
7×3=21
x=7
2x=7×2x
2×7=14
Answer: 14
Step-by-step explanation:
56 / 4 = 14
D 17x
This is because you’re not adding or subtracting months from your 17 letters. So cross A and C out. And you’re not dividing the number of letters by months. So cross B out. You’re left with D and this is correct because 17 letters EACH month. EACH is telling us that you multiply 17 and x.
We have an equation and we know the values of the variables p, r, and t.
Plug in the values.
I = (8000)(0.6)(1)
I = 4800
So, I is equal to 4800.
