Make y the subject:
y = 6 - x
Now, use Elimination.
0 = 3x - 3
Divide both sides by 3:
0 = x - 1
So x = 1.
Substitute back into the equation:
y = 6 - (1)
So y = 5.
Hence, the answers are x = 1, y = 5.
Answer: Yes.
Step-by-step explanation: 4:8 simplifies to 1:2, since he used half as many rainbow charms as he did white stars. 5:10 also simplifies to 1:2. If they both have half as many rainbow charms as white, then both of his sister’s bracelets keep the same ratio.
Yes, the input and output are both possible.
Reason~
Given that the possible solution is (20,20),
<u>Input</u> = x = 20
<u>Output</u> = x = 20
Thus, g(20) = 20, which is clearly possible.

Answer:
2000 people
Step-by-step explanation:
The area of the gym is the width times length:
A = wl
A = (50 ft) (100 ft)
A = 5000 ft²
Write a proportion:
1 person / 2.5 ft² = x / 5000 ft²
x = 2000 people
For this case we propose a system of equations:
x: Variable representing the weight of large boxes
y: Variable that represents the weight of the small boxes
So
We clear x from the first equation:
We substitute in the second equation:
We look for the value of x:
Large boxes weigh 50 pounds and small boxes weigh 30 pounds
Answer:
Large boxes weigh 50 pounds and small boxes weigh 30 pounds
