If you know that x = -4, then you can use this to find y <span>by plugging it into -3 = 5y - 2x</span>
I'm assuming the blueprint shows 1 inch is equal to 10 ft. This means that 1 inch on the blueprint corresponds to 10 feet in real life.
We have the ratio
1 inch: 10 feet
If we multiply both sides by 0.5 then,
0.5*(1 inch) : 0.5*(10 ft)
0.5 inch : 5 feet
So 0.5 inches (aka half an inch) on the blueprint corresponds to 5 feet in real life.
Answer: A) 5 feet
She is going to practice piano for 80 minutes. First you want to divide the number of minutes in the lesson by 5 to find how many times 5 minutes goes by in 20 minutes. Next you want to multiply your answer for that, which should be 4, by the amount she wants to practice. So you do 4 x 20, and get 80 minutes total.
Answer:
( -2,-3) is the midpoint
Step-by-step explanation:
To find the x coordinates of the midpoint, add the x coordinates of the endpoints and divide by 2
( -1+-3)/2 = -4/2 =-2
To find the y coordinates of the midpoint, add the y coordinates of the endpoints and divide by 2
( 3+-9)/2 = -6/2 =-3
( -2,-3) is the midpoint
