Answer: C. She is dividing the entire length into shorter lengths.
The rest of the question would be "How many pieces will she get?"
Step-by-step explanation:
A would be a subtraction problem UNLESS it goes on to ask "how many 1/3 yard pieces can she cut?"
It's a subtraction problem if it's about "how many yards are left?"
B is just backwards and makes no sense with the expression given.
The direct variation equation relates x and y is y =
x
Step-by-step explanation:
Direct variation is when one variable is equal to a constant times another variable
If y varies directly with x, then
- y ∝ x
- y = k x is the equation of variation
- k is the constant of variation
∵ y varies directly with x
∵ y ∝ x
∴ y = k x
∵ y = 10 when x = 3
- Substitute these values in the equation above to find k
∴ 10 = k(3)
∴ 10 = 3 k
- Divide both sides by 3
∴ k = 
∴ The equation of variation is y =
x

Answer: ???
Step-by-step explanation: what do you need help with
?
1/3x+y=10/8
Times 1/2 for both side
1/6x+1/2y=5/8
-
1/6x+1/5y=13/6
=
3/10y=-1/2
Divided 3/10 for both side
y=-5/3
1/3x+y=10/8
1/3x-5/3=10/8
1/3x=70/24
1/3x=35/12
x=35/4
x=8 3/4. As a result, the solution set is (8 3/4,-5/3). Hope it help!
