Answer:
45/1
Step-by-step explanation:
45x is the rate at which the line goes up
The slope is y=3x-2, or if you had to rewrite it, 3x-2 is the slope. The y intercept could be found using the previous formula, y=3x-2. If x were to be equal to 5 for example, you would have to multiply that by 3, then subtract it by 2, and you get your y intercept, which would equal 13 (THIS IS AN EXAMPLE).
Find how much it grew:
53 - 20 = 33 inches.
Divide the amount it grew by the original length
33/20 = 1.65
Subtract 1:
1.65 - 1 = 0.65
Multiply by 100 for percent:
0.65 x 100 = 65%
The percent increase is 65%
Answer:
51/25 and 27/4
Step-by-step explanation:
distributing and dividing both sides by coefficient of x
Answer:
Step-by-step explanation:
27 ÷ 90 = 0.3 = 0.30 = 30%
