There are many ways to solve this problem. All you have to do is simple algebraic manipulation. Solve for b and h with the two simpler equations:
2b = 12; divide 2 on both sides to get b = 6
h - x = 2; add x to both sides to get h = (2 + x)

Plug this stuff into the first equation to solve for x. Once we solve for x, we can plug that x value into the equation for h. Because you can see we didn’t get an actual numerical value for h. So:
x + (2+x) + 6 = 14
Subtract 6 from both sides and distribute that plus sign to get rid of the parenthesis. Then combine the like terms to get:
2x + 2 = 8
Subtract 2 from both sides and divide by 2 to get x = 3

Finally plug it into the equation for h:
h = 2+3 = 5

lys-0071 [83]

Answer: See explanation

Step-by-step explanation:

6 sacks of potatoes weigh 122.4 kg

1 sack would weigh 122.4 kg ÷ 6

122.4 ÷ 6 = 20.4

1 sack of potatoes weighs 20.4 kg

4 sacks of onions weigh 50 kg

1 sack would weigh 50 kg ÷ 4

50 ÷ 4 = 12.5

1 sack of onions weighs 12.5 kg

grin007 [14]
The cable should be 50 feet.

If you draw the picture, you will see that you have a right triangle.

Let's just use the Pythagorean Theorem to find the hypotenuse (or cable).

30^2 + 40^2 = c^2
2500 = c^2
50 = c
