7x5=20+8+ Fill in the missing number to make the equation true

1 answer:

3 0

Answer: 7

step-by-step:
okay so first you do 7*5 which is 35 and 20+8 which is 28

then you get 35=28+x (the x is the ‘missing number’)

to find x you subtract 28 from both sides to keep the equation balanced

35-28=28-28+x

so 35-28 is 7 and 28-28 is 0 so then you have 7=x and your answer is 7

you’re doing algebra but instead of using variables your teacher is saying find the ‘missing number’ haha

The diameter of the wheel of a cart is 856 m, it will cover 2690.28 m in 56 complete revolutions.

Anvisha [2.4K]

It looks like the question you are asking is how far will the cart travel after 56 complete revolutions.

To answer this you will use the distance it will travel in 1 revolution (2690.28 m) and multiply it by 56.

2690.28 x 56 = 15655.68 meters or about 15.66 km.
