I think it's square and hexagon.
Answer:
Solve the following system for x and y:
{2 x + 53 = 53, 8 x + 3 = 42}
Check whether x and y are present in the given system:
Answer: The variable y is not present. Therefore its value cannot be determined.
Step-by-step explanation:
Answer:
3 m : 4 cm, 3 m/4 cm, 3 m to 4 cm
Step-by-step explanation:
The actual playground will have an area of 72 m², and have one side be double the other, because the scale drawing does so too.
We can make a system of equations: l * w = 72, l = 2w
Substitute: 2w * w = 72
Simplify: 2 * w² = 72
Divide: w² = 36
Square root: <em>w = 6 m</em> (no negatives due to distances always > 0)
Substitute: l = 2 * 6 m
Simplify: <em>l = 12 m</em>
This means that the relations of one side is <em>6 m : 8 cm</em>. That can be simplified to 3 m : 4 cm.
Answer:
l think they meet when collecting like terms.maybe like this
y=4x8
y=3x+1
=(4×+3x)+1+8
