Its super easy all u have to do is go on tiger math and the first link will take you to it and u put in the question and it will give you a step by step how to do it and it will give you the answer
Step-by-step explanation:
4x +13 +79+79+ 11x-6 = 360
15x +165 = 360
15x = 195
x =13
QRS = 11(13)-6 = 137
Answer:
105 children
Step-by-step explanation:
35/100×300
105
Let x represent the amount of dimes
Let y represent the amount of nickles
So since he has 20 coins, x + y = 20
and if we want to find the total money of dimes, we have to multiply x with 10
So 10x + 5y = 165 (in cents)
2x + y = 33
-x - y = -20
x = 13
so x = 13 and y = 7
Hope this helps :)
