Answer:
The numbers are -15 and 100
![\frac{2}{10} +\frac{-15}{100} =\frac{5}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B10%7D%20%2B%5Cfrac%7B-15%7D%7B100%7D%20%3D%5Cfrac%7B5%7D%7B100%7D)
Step-by-step explanation:
we have
![\frac{2}{10} +\frac{x}{100} =\frac{5}{y}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B10%7D%20%2B%5Cfrac%7Bx%7D%7B100%7D%20%3D%5Cfrac%7B5%7D%7By%7D)
Solve the left side
![\frac{2}{10} +\frac{x}{100} =\frac{20+x}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B10%7D%20%2B%5Cfrac%7Bx%7D%7B100%7D%20%3D%5Cfrac%7B20%2Bx%7D%7B100%7D)
so
![\frac{20+x}{100}=\frac{5}{y}](https://tex.z-dn.net/?f=%5Cfrac%7B20%2Bx%7D%7B100%7D%3D%5Cfrac%7B5%7D%7By%7D)
equate the numerators and the denominators
20+x=5 ------> x=5-20=-15
100=y -------> y=5
therefore
The numbers are -15 and 100
![\frac{2}{10} +\frac{-15}{100} =\frac{5}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B10%7D%20%2B%5Cfrac%7B-15%7D%7B100%7D%20%3D%5Cfrac%7B5%7D%7B100%7D)
Answer:
less
Step-by-step explanation:
An increase of 20% makes the price 120% of the original price.
A discount of 20% makes the discounted price 80% of the previous price.
Original price: x
20% increase in price: 1.2 * x
20% discount over the raised price: 0.8 * 1.2 * x
Now we multiply the numbers in the last expression and compare the result with x.
0.8 * 1.2 * x = 0.96x
0.96 is less than x, so the customer pays less than the original price.
A) 42,000m divided by 2 1/3 = 18,000m divide by 1000m to get km = 18km/hr
B) 18,000m divided by 60 to get minutes = 300m divide by 60 to get seconds = 5m/sec.
Answer:
The slope is 24
Step-by-step explanation:
Use any two points in the graph to find the slope of the graph
- - - - - - - - - - - - - - - - - - - -
Step 1. Use two points
Ex: (10, 320) & (5, 200)
Step 2. Find the slope using the two points
m = slope
m = change in y/change in x
m = (y2 - y1)/(x2 - x1)
m = (200 - 320)/(5 - 10)
m = -120/-5
m = 120/5
m = 24
The slope of the graph/line is 24
