Answer:
- x = 37 1/2
- x = 2
Step-by-step explanation:
Parallel lines divide transversals proportionally. I like to write the proportions so the variable is in the numerator. Then the solution is obtained by multiplying by the denominator of the variable term.
1. x/20 = (46 -16)/16
x = 20(30/16)
x = 37.5
__
2. (x +4)/13.5 = 4/9
x +4 = 13.5(4/9) = 6
x = 6 -4
x = 2
Answer:
The one all the way to the right
Step-by-step explanation:
30 ÷ X = 6
30 ÷ 5 = 6
Answer:
The length of the yard is 60 feet while the width is 30 feet.
Step-by-step explanation:
If the length of Mr. Timmon's backyard is double the width, then the dimensions are related by the following expression:
length = 2*width
We also know the perimetter, since he has the exact length of fence to surround his whole yard, which is 180 feet. The perimeter of a rectangle is given by:
perimeter = 2*length + 2*width
Therefore,
180 = 2*length + 2*width
With the length being double the width, we have:
180 = 2*(2*width) + 2*width
180 = 4*width + 2*width
6*width = 180
width = 180/6 = 30
length = 2*width = 2*30 = 60
The length of the yard is 60 feet while the width is 30 feet.
5 * 10^9 * 2.3 * 10^7
= 5 * 2.3 * 10^9 * 10^7
= 11.5 * 10^16
= 1.15 * 10 * 10*16
= 1.15 * 10^17
