The diagram shows a square. (7x + 3)cm (5x + 8) cm
Find the length of the side of the square.

x = 5/2cm

Step-by-step explanation:

Because this is a square and each side is equal to each other in length, we can say:

7x + 3 = 5x + 8

We can start rearranging this equation to collect like terms:

7x = 5x + 8 - 3

7x = 5x + 5

7x - 5x = 5

2x = 5

x = 5/2

We can test this out by substituting our new found value for x into the original equation:

7 * (5/2) + 3 = 5 * (5/2) + 8

(35/2) + 3 = (25/2) + 8

I'm going to change the integers (3 and 8) to fractions so the arithmetic is easier, as they'll all have the same denominator.

(35/2) + (6/2) = (25/2) + (16/2)

(41/2) = (41/2)

So as you can see above, with x = 5/2, both sides are equal.

You don't need to put the fractions in brackets; I just do that to make it look a little less messy.

Also, I've only included the units (cm) in the answer. I don't like using units when doing calculations, but your teacher may ask you to perform the calculations using the units throughout.

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
