Answer:

13

Explanation:

Because 4 times ? decreased by 7=45 then what times 4 =52 since it was decreased by 7 then 45+7=52.

We know it has to be more than 10 so what is 11 x 4=44 12 x 4=48 and 13 x 4=52 so 52 subtracted by 7=45 and there's your answer.

hope this helps have a great day:)

Set up an equation :

4 x number - 7 = 45

Add 7 to both sides:

4 x number = 52

Divide both sides by 4:

Number = 13
