Equation 1:
x = (5y+11)/2
Substitute equation 1 to 2:
-2((5y+11)/2)+ 3y=-9
-2/2 = -1 thus -1(5y+11)
Continue...
-(5y+11)+3y=-9
-5y-11+3y =-9
(-5+3)y= 11-9
-2y = 2
y=-1
Substitute y into equation 1:
x=(5*-1+11)/2
x = 6/2=3
So y=-1 and x =3
Answer:
-7 feet above the ground
Step-by-step explanation:
Answer:
60
Step-by-step explanation:
There will be two squares.
Think about it: The shorter side is 3.5 feet. The longer side is 7 feet. If he cuts it in half on the longer side, he's taking the length of that longer side, and dividing it by 2. 7/2=3.5.
So, you'd have two squares, both with a length and width of 3.5 feet.
One-sixth of an hour is 10 minute
10 minutes 3/4 chapter
Therefore, 10 minutes x 6= 3/4x6
