Answer:
[12, 15]
Step-by-step explanation:
{6x + 5y = 147
{8x + 4y = 156
-¾[8x + 4y = 156]
{6x + 5y = 147
{-6x - 3y = -117 ← New Equation
________________
2y = 30
___ ___
2 2
y = 15 [Plug this back into both equations to get the x-coordinate of 12]; 12 = x
So, using the Elimination Method, what I did here was took the bottom equation and multiplied it by -¾, turning 8x to -6x, canceling out all <em>x-terms</em><em>.</em><em> </em>It does not matter which variable you choose to eliminate, as long as you know what you are doing.

Answer:
width = 8 ft & length = 32 ft.
Step-by-step explanation:
let the width be x and length be 4x.
we know, Perimeter = 2(l+b)
now,
2(4x + x) = 80
10x = 80
x = 80/10 = 8
x = 8
therefore,
width = x = 8 ft
length = 4x = 4 × 8 = 32 ft.
hope this helps you !
Answer:
Mark 3 and subtract 1 from each division
Step-by-step explanation:
Tara will mark the number line at point 3.
Then she will subtract 1 from 3 and mark at point 2.
Again subtracting 1 from 2 the next mark is at 1.
And the last mark is at 0.
The first mark at point 3 shows that the string is 3 feet long.
Now we need 1 foot divisions. So we subtract from 1 division from point 3 to get 1 foot long string. So we continue to get 3 equal parts each of 1 foot long by dividing the 3 feet long string into 3 equal divisions.
so the first piece is from 0-1 gives 1 foot long string
The 2nd piece is from 1-2 gives 1 foot long string
The 3rd piece is from 2-3 gives 1 foot long string
2 * (2*3.14*R) =
2 * (2*3.14*70) = 879,2
so the answer is about 879,2 meters
