1/5 = 0.2 = 20%
100% - 20% - 10% = 70%
He left 70%

Answer:
k = 5/3
x = 21
Step-by-step explanation:
Here, we have two similar shapes
The scale factor here would be the ratio of the corresponding similar sides
so we have k as 15/9 = 5/3
To find the value of x
When two shapes are similar, the ratio of the sides corresponding are equal
So we have it that;
x/35 = 9/15
= 15 * x = 9 * 35
15x = 315
x = 315/15
x = 21
Let's begin by listing out the information given to us:
This is perpendicular to the line
The equation is already in the slope-intercept form:
The slope of the parallel line is given by:
We proceed by substituting the values of x & y into the new equation, we have:
Answer:
28
Step-by-step explanation:
Difference means subtraction.
10 - (-18) = 28
2 negatives make a positive.
