Answer: (-1,2)
Steps:
Solve by elimination
Multiply the first equation by 2 to make the coefficients of x in both equations the same
2(x+2y=3)
2x+4y=6
Then line them up and subtract
2x+y=0
-2x+4y=6
= -3y=-6
Divide both sides by -3 to isolate y
y=2
Then substitute 2 for y into one of the equations to find x.
x+2(2)=3
x+4=3
x=-1
Answer:
132
Step-by-step explanation:
13/10+2/100=?/100
Get a common denominator of 100 for the first term
13/10 * (10/10) +2/100=?/100
130/100 + 2/100 = ?/100
132/100 = ? /100
Answer:
h =
Step-by-step explanation:
S = 2πr² + 2πrh ( subtract 2πr² from both sides )
S - 2πr² = 2πrh ( isolate h by dividing both sides by 2πr )
= h
I'm thinking you'll need four strips. Each one is 1/3, so to create a whole foot, you'd need three.
So I would say you would need 36 strips, as 12 * 3= 36.
