Answer:
Step-by-step explanation:
3x - 4y = 13 (1)
2x + y = 5 (2)
——————
3x - 4y = 13
4(2x + y = 5) (2) times 4
——————-
3x - 4y = 13
8x + 4y = 20
——————-
11x = 33
x = 33/11
x = 3
Plug x = 3 in (2):
2(3) + y = 5
6 + y = 5
y = 5-6
y = -1
Thus, x = 3 and y = -1
Answer:
3 x 2/3 = 6/3
Step-by-step explanation:
2/3 for each one. There are three. there are 6 shaded. If you take the two from the last one and add to the other ones, it will be two wholes. 6/3 = 2.
Let's solve this problem step-by-step.
STEP-BY-STEP SOLUTION:
= 1 / 8 + ( - 5 / 12 ) - 3 / 8
= 1 / 8 - 5 / 12 - 3 / 8
= ( 3 - 10 - 9 ) / 24
= - 16 / 24
= - 2 / 3

This is my go at the problem.
Let x be the original price.
72/100=6/100 of x.
so,
x=72/100 ÷ 6/100= $12.00
The answer is $12.00
Hope this helps!
X=2/3y because you want to know what roberts time is
