Answer:
3(2x+5)=3 6x+15 = 3 6x = -12 x =-2
9+9x=2x+2 9x-2x= 2-9 7x= -7 x=-1
Step-by-step explanation:
The ratio of Red Apples to Green Apples is 5:2. The proportion of red apple is 5/7.
The store sold 45 red apples.
So the combined amount of red and green apples sold = No of red apples sold divided by the proportion of red apples = 45/ (5/7) = 63
The combined amount of red and green apples sold is 63 apples.
Round 2.81 to 2.8 and 3.72 to 3.7. Add both together to get 6.5
