Answer:
40 feet
Step-by-step explanation:
We know that the area of a rectangle is represented as
, where l is the length and w is the width.
We already know the width, and we know the area, so we can plug these values into the equation.

Our goal is to now isolate the variable l, and to do this we can divide both sides by 6.

Hope this helped!
Answer:
Find the attached
Step-by-step explanation:
We are given the following linear equation;
-3y = 2x - 7
In order to graph it, we need to determine at least 3 pairs of points that lie on the line;
we first solve for y by dividing both sides of the equation by -3;
y = (-2/3)x + 7/3
let x be 3;
y = (-2/3)*3 + 7/3
y = 1/3
(3, 1/3)
let x be 6;
y = (-2/3)*6 + 7/3
y = -5/3
(6, -5/3)
let x be 9;
y = (-2/3)*9 + 7/3
y = -11/3
(9, -11/3)
Using the three set of points we graph our linear function. Find the attached;
Answer: she must complete 4 levels to have a point fewer than 20
Step-by-step explanation:
Given the following :
Starting point = 100 points
Passing a level = - 8 points
Catching a flower = - 3 points
Suppose Tina catches 6 flowers per level
Number of levels she must complete to have fewer Than 20 points
Total number of points lost per level:
Catching 6 flowers = -(6 × 3)
Passing the level = - 8
= - 18 + - 8 = - 26 points
Number of levels she must complete to have < 20
Let number of levels = y
Starting points - (26 × number of levels) < 20
100 - (26y) < 20
100 - 26y < 20
-26y < 20 - 100
-26y < - 80
y > 80/26
y > 3.07
Hence she must complete 4 levels to have a point fewer than 20
