Answer:
I got 35
Step-by-step explanation:
Answer:
x = 4
Step-by-step explanation:
20x + 12 = 22x +4
12 - 4 = 22x - 20x
8 = 2x
4 = x
The denominator must be the same, so just think of the LEAST COMMON MULTIPLE, The LCM here is 8, because you can multiply 4 by 2 to get 8.
so when you multiply, you multiply both on the top and on the bottom, so this would be:
3 x 2 / 4 x 2 = 6 / 8
Now you can add or subtract: 6/8 - 1/8 = 5/8
.05 is the answer, when converting a percent to a decimal, move the decimal point twice to the left.
Answer:
The constant of variation is 1.6.
Step-by-step explanation:
y = kx and x = 5 when y = 8 and k = the constant of variation.
8 = k*5
k = 8.5 = 1.6.
