Answer:
x = 10.353, y = 8.706
Step-by-step explanation:
2x+y = 28 eqn..(1)
–3x+7y = 26 eqn..(2)
Transpose y in eqn(1), which is;
2x+y = 28; y = 28–2x
Plug in y in eqn(2)
–3x+7(28–2x) = 26
–3x–14x+196 = 26
–17x = 26–196
–17x = –176
x = 10.353
plug in x in any of the eqn..
2(10.353)+y = 28
20.706+y = 28
y = 28–20.796
y = 8.706
To get the answer we can use proportion. We know that 4$ its 100% and 4.32 its 100% + taxes.
4$ ---------- 100%
4.32 -------- x
crossmultiply now
4x=4.32*100%
4x=432% /:4
x=108%
We know that 4.32 its 100% + taxes=108% so to get taxes we have to subtract 108-100.
108%-100%=8% - its the answer.
I am pretty sure it is a and b because they all are in a data relationship.
Answer:
The area of one slice of pizza is 18 in²
Step-by-step explanation:
First we have to know that the 360 ° representing the circle expressed in radians are expressed as 2π
Now we must calculate the area of the circle
a = π * r²
a = π * (12in)²
a = 144π in²
Now that we have the area of the circumference we multiply it by (π/4) / (2π)
144π in² * (π/4) / (2π) =
144 in² * 1/8 =
18 in²
The area of one slice of pizza is 18 in²
