Answer:
Heres the answer
Step-by-step explanation:
To calculate the ratio of an amount we divide the amount by total number of parts in the ratio then multiply the answer by original ratio.
8+7=15
75 divided by 15 = 5
Each unit =5
8 x 5 = 40, so Debbie gets 40 smarties
7 x 5 = 35, so Dave gets 35 smarties.
3A+2B=20
2A+B=13 ➡×(-2)➡-4A-2B=-26
3A+2B-4A-2B=20-26
-A=-6 ➡A=6
2(6)+B=13➡B=1
