If 2x+y=5, then y=5-2x, so he substituted 5-2x correctly.
x+4x=5x, so he combined like terms correctly.
If 5x-10=10, then 5x=10+10 -> 5x=20, so he subtracted 10 from the right side instead of adding 10 to the right side.
The answer is C.
Here's the correct solution:
Answer:
smaller number = 3 5/24
larger number = 6 13/24
Step-by-step explanation:
let the larger number = x
smaller number = y
x - y = 3 1/3 equation 1
2(x +y) = 191/2 equation 2
divide equation 2 through by 2
x + y = 9 3/4 equation 3
subtract equation 1 from 3
2y = 6 5/12
y = 77/12 x 1/2 = 3 5/24
substitute for y in equation 1
x - 3 5/24 = 31/3
x = 3 1/3 + 3 5/24
x = 6 13/24
Answer:
Exact quotient is 0
Step-by-step explanation:
Given : 
is the same as 1÷3.
To find : What is the exact quotient in decimal form of 1÷3
Solution : Here the divisor is 3
dividend is 1
To find quotient we divide divisor by dividend
1÷3 or = 0.333...
So, the quotient is 0.333... and remainder goes on to 1 till the division goes on.
Exact quotient in decimal form is 0
