The sum of the sides of a quadrilateral is equal to 360º.
x= 4th angle measurement
We have the following equation:
90+156+28+x=360
x=360-90-156-28
x=86
Answer: the size of the 4th angle would be 86º.
P = 1/2 x 1/2
P = 1/4 or 25%
Answer:
Initial cost for a job = $2
Step-by-step explanation:
Let initial cost be $x.
Fixed amount for each copied page = $y
John:
Fixed amount for 425 pages = 425*y = 425 y
x + 425y = 10.50 ---------------(i)
Peter:
Fixed amount for 300 pages = 300 * y =300y
x + 300y = 8 ---------------------(ii)
Multiply (ii) by (-1) and add the both equation. Thus x will be eliminated.
(i) x + 425y = 10.50
(ii)*(-1) <u>-x - 300 y = - 8</u>
125y = 2.50
y = 2.50/125
y = $ 0.02
Plug in y value in equation (i)
x + 425*0.02 = 10.50
x + 8.50 = 10.50
x = 10.50 - 8.50
x = $2
