Answer:
C. (2, 1)
Step-by-step explanation:
-3y = x-5
x+ 5y = 7
Subtract x from both sides in the first equation. Write the second equation below it.
-x - 3y = -5
x + 5y = 7
Add the two equations above.
2y = 2
Divide both sides by 2.
y = 1
Substitute y with 1 in the second original equation and solve for x.
x + 5(1) = 7
x + 5 = 7
Subtract 5 from both sides.
x = 2

Answer:
25.
Step-by-step explanation:
The number of women employed = 100 - 65 = 35.
So the number of men paid weekly = 60 - 35
= 25.
Take 49 and divide it by 7 and you get 7. 7 times 10 is 70. Your answer is $70.
3x2 is six. If you do that across, you would get 6/6 for both. 6/6 - 6/6 is how much?
The answer is going to be 60m^2
