The answer is C
10% = 0.10
12 x 0.10 = 1.20
12 - 1.20 = 10.80
The first inequality(A) is a function to used it. based on the distance rather than the other
Answer:
The solution of system of equation is (-4,-2)
Step-by-step explanation:
The given system of linear equation is
Equation 1: 2x+y=(-10)
Equation 2: 3x+4y=(-20)
Using the Elimination method:
Important step: First multiply equation 1 by 4
we get,
Equation 3: 4(2x+y)=(-40)
Equation 3: 8x+4y=(-40)
Now,
8x+4y=-40 Equation 3
3x+4y=-20 Equation 2
- - +
________
5x+0=(-40)+20
5x=(-20)
x=(-4)
Replacing value of x i any equation
2x+y=(-10)
2(-4)+y=(-10)
(-8)+y=(-10)
y=(-2)
Thus,
The solution of system of equation is (-4,-2)
So you have length
l=legs and b=base
the first perimeter is 2l+b=8.5 since there are 2 legs
the second perimeter is 4l+b=15.5 since the legs are now 2l long instead of l
subtract the top problem from the bottom problem
(4l+b)-(2l+b)=15.5-8.5
2l=7 so l=3.5
if l=3.5 and 2l+b=8.5, 7+b=8.5, so b=1.5
check by plugging it into the second perimeter
4(3.5)+1.5=15.5-->14+1.5=15.5 it's correct yay!
Answer:
25x-4
Step-by-step explanation:
5x^2=5x multiplied by 5x= 25x
25x-4 is simpliest form and evaluated
Have a great day, and good luck!
