Answer:
r = 4/(x+y)
Step-by-step explanation:
rx + ry = 4
Factor out r
r ( x+y) = 4
Divide each side by (x+y)
r ( x+y) /(x+y) = 4/(x+y)
r = 4/(x+y)
Answer:
g = -3
Step-by-step explanation:
-7g + 5 = 2 – g – 7g
Combine like terms
-7g + 5 = 2 -8g
5 = 2 + -g
3 = -g
-3 = g
Answer:it would be 40 eggs
Step-by-step explanation:
10 divided by 5= 2(eggs per day)
Then times 2 by 20 to get the answer of 40 eggs in 20 days
36/54 = x/100
54x = 100 * 36
54x = 3600
x = 3600 ÷ 54
x = 66.666666.... so 66.67
First put it into a proportion and then cross multiply. After that you divide both sides by 54 to get x alone which gives you 66.66666 which is rounded to 66.67
Answer: 66.67%
My guess would be: 3 x(times) 500+80+4
