2 because you make them with the same denominators that both go into each other EX: 8x9=72 7/8 now equals 63/72 and 4/9 now equals 28/72 now add them together 63/72 + 28/72= 91/72= 1 19/72
Answer:
The answer to your question is $21.0
Step-by-step explanation:
Data
Original price = $25
Discount = 20%
Taxes = 5%
Process
1.- Calculate the price with the discount
$25 ------------------- 100%
x ------------------- 20%
x = (20 x 25) / 100
x = 500 / 100
x = $5
Price after the discount = $25 - $5
= $20
2.- Calculate the price after taxes
$20 ---------------------- 100%
x ----------------------- 5%
x = (5 x 20) / 100
x = 100 / 100
x = $1
Final price = $20 + $1
= $21
A rectangle, is a quadrilateral with all angles at 90°.
a square is a quadrilateral with all equal sides, and right-angles all around.
now, the rectangle as well as the square, have all right-angles, the only difference is that the square has all equal-length sides, whilst a rectangle can have pairs of sides that vary in length.
Answer:
Train A = 299 tons Train B = 50 tons
Step-by-step explanation:
Train A = x
Train B = y
x+y = 349
x= y +249
Plug in one equation into another
y+249+y= 349
Simplify
2y+249=349
Subtract 249 from both sides
2y=100
Divide both sides by 2
y=50
Plug it into the x equation to solve for x
x+50=349
-50 from both sides
x=299
