Step-by-step explanation:
First I do it as separate equations 2x-7=0 and 5x+3=0. In this equation you get two answers so you first answer 2x-7=0
2x-7=0
+7 +7
2x=7
/2 /2
x=7/2
Then do 5x+3=0
-3 -3
5x=-3
/5 /5
x= -3/5
Then you can check by putting them back in.
Based on the amount of oranges bought, those sold at a profit and those sold at a loss, the overall profit is 14.2%
<h3>What is the overall profit?</h3>
Assume that the buying price was $1 each.
The amount earned from 60% of them is:
= 60% x 100,000 x 1
= $60,000
The profit from selling 50% of the remaining is:
= (50% x 40,000) x 1.60
= $32,000
The loss from selling the other 50%:
= (50% x 40,000) x 0.90
= $22,222.22
Total selling price:
= 60,000 + 32,000 + 22,222.22
= $114,222.22
Total profit:
= (114,222.22 - 100,000) / 100,000
= 14.2%

Answer:
y=7/5x+7
Step-by-step explanation:
The slope is 7/5 and the y-intercept or b is 7.
Hope this helped :)
Answer:
2S = F
1.5R = S or R = S/1.5
So flour F and sugar S and raisins R
F + S + R = 550
2S + S + S/1.5. = 550
3S + 1.5S + S = 550*1.5
5.5 S = 550*1.5
S = 100*1.5
S = 150
R= 100
And so flour ie, F = 300
