I need help this is very hard please

7 + 6 = 9 + 4

16 - 7 = 3 + 6

20 x 6 = 60 x 2

2 x (3 + 5) = 20 - 4

3 + (3 x 6) = 3 + 3 + 15

Given that, we have to find the missing numbers in each equation

Let the unknown be "x"

7 + x = 9 + 4

Solve the right side of equation, 9 + 4 = 13

7 + x = 13

x = 13 - 7

x = 6

Let the unknown be "x"

16 - 7 = 3 + x

Solve the left side of equation, 16 - 7 = 9

9 = 3 + x

x = 9 - 3

x = 6

Let the unknown be "x"

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.

it would take 7/10 of an hour too fill the pool.
