If the 5 of them weigh 1/4 of a ton
then 1 of them weigh x
5/1 = 1/4//x Do you see what happens? Just by writing down the givens you get a proportion. It will work better for you if you change the 1/4 to 0.25
5/1 = 0.25/x Now it looks like an ordinary proportion. Cross multiply
5x = 0.25*1 divide by 5
x = 0.25/5
x = 0.05 tons. We better change this to pounds.
1 ton = 2000 pounds
0.05 ton = x
1/0.05 = 2000/x Cross multiply
x = 2000 * 0.05
x = 100 pounds.
Answer:
Part a) The value of x is 10
Part b) The perimeter of triangle JKL is 
Step-by-step explanation:
Part a) Find the value of x
we know that
The <u>Triangle Proportionality Theorem,</u> states that if a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally

Part b) we know that
The perimeter of triangle JKL is equal to

substitute the values

substitute the value of x

Answer: x = 1
Explanation:
Let x be the unknown number.
Thus:
2x + (14 • 2) = 30
2x + 28 = 30
2x = 30 - 28
2x = 2
x = 2/2
x = 1
Twenty-eight and five-sevenths. 28 5/7
