Answer: 0.89z
Think of it like 100% - 11% = 89%
You save 11%, so you need to pay the remaining 89%
Taking 89% of z then leads to 0.89z
So that's why z - 0.11z = 0.89z
Answer:
The values of x is 0 and 2.
Step-by-step explanation:
Given that the perimeter and area are the same so we can assume that x value remains the same in both equation. In order to find x, we can compare the equations and solve it :
A(y) = x² - 4x + 4
P(y) = -2x + 4
A(y) = P(y)
x² - 4x + 4 = -2x + 4
x² - 4x + 4 + 2x - 4 = 0
x² - 2x = 0
x(x - 2) = 0
x = 0
x - 2 = 0
x = 2

why? cause i dont live there
Answer: 
r=26
Step-by-step explanation:
Given: Mrs. Morton rewards her students on behave well by putting 3 marbles into a marble jar.
If the jar contains 24 marbles. and r represent the number of additional times the class is rewarded then the required equation will be
If we solve it, we will get the minimum the jar contains 24 marbles.
To solve equation, subtract 24 from both sides, we get
Hence, the minimum whole number of additional times they need to be rewarded so they can have a party=26
We first get the gradient of the equation of a line by taking the
change in y over change in x
Hence our gradient will be
(6-9.5)/(8-1)=-3.5/7=0.5
Taking an arbitrary point(x,y) and using our gradient we get
and one of the points above we get
(y-6)/(x-8)=0.5
y-6=0.5*(x-8)
y-6=0.5x-4
y=0.5x+2 or y=1/2x+2
which is the line of our equation the answer we are
asked for.
