Answer:
The width is 
Step-by-step explanation:
The perimeter of the rectangular yoga mat can be found using the formula;
.
.
It was given that the width of the mat is eight less than half the length.
We put equation (2) into equation (1) to get;
.
.
.
Divide both sides by 3;
We put into equation 2 to get;
46 and 19. 46 x 19 = 874 and 46 - 19 = 27
Answer:
Step-by-step explanation:
let x represent the number of MB used in a month.
Let y represent the monthly cost of using x MB.
If we plot y on the vertical axis and x on the horizontal axis, a straight line would be formed. The slope of the straight line would be
Slope, m = (36 - 24)/(7 - 3)
m = 12/4 = $3
We would represent the linear equation in the slope - intercept form which is expressed as
y = mx + c
Where
c = y intercept
m = slope
At the y intercept, x = 0. Therefore, the y intercept is the flat monthly fee of $15. It is charged whether MB is used or not. Therefore, the linear equation is
y = 3x + 15
Or
C(x) = 3x + 15
