Answer:
The perimeter of a rectangle is the sum of both lengths and both widths, which is equal to 54 meters. Let's call Length L and Width W.
The question is saying this: L = 3 meters + 3(W). We have 2 variables, which means we need at least 2 equations to solve. So far we have one, our second equation is from the perimeter.
2 lengths + 2 Widths = 54. Now, it's just a plug and chug.
2(3 + 3W) + 2W = 54.
6 + 6W + 2W = 54
8W = 48
W=6
L = 3 + 3(6) = 21
To double check: 2(21) + 2(6) = 42 + 12 = 54
The Width is 6 meters, and the Length is 21 meters.
Answer:
105/61 is the answer for 5/6 ÷ 10/21
Answer:
(0, 3)
Step-by-step explanation:
1. Find the slope:

2. Calculate the y-intercept using a given point:
(-8, -3)
-3 =
+ b
-3 = -6 + b
-3+6 = -6+6 + b
3 = b
3. Write in slope intercept form:

Therefore, the y-intercept is 3.
The graph for this table is shown below.

Answer:
y = ± 12
Step-by-step explanation:
Given
y : 24 = 6 : y, or in fraction form
=
( cross- multiply )
y² = 144 ( take the square root of both sides )
y = ±
= ± 12
