Answer:
60 mph and 40 mphStep-by-step explanation:
Let the speed of the car = x and the speed of the truck = y
We have following equations:
180/x = 120/y x = y + 20Simplify the first equation and substitute x:
180y = 120x2x = 3y2(y + 20) = 3y2y + 40 = 3y3y - 2y = 40y = 40Find the value of x:
x = 40 + 20 = 60Car's speed 60 mph
Truck's speed 40 mph

6x-6y=23 find y when x=8
Answer:
y= 4.166
If rounded to the nearest tenth
y = 4.2
Step-by-step explanation:
6x - 6y = 23
x = 8
6x - 6y = 23 (Sub in the x with 8)
6(8) - 6y = 23
48 - 6y = 23 (Subtract each side by 48)
-6y = 23 - 48
-6y = -25 (Divide each side by -6)
y = 4.166
If rounded to the nearest tenth
y = 4.2

If three independent events happen one after the other, which of the following sample space tools cannot be used?
a list
a tree diagram
a table
If three independent events happen one after the other, a list of the sample space tools cannot be used.
correct option: A list
What is an independent events?If the likelihood of the occurrence of one event has no bearing on the likelihood of the other, then the two occurrences are independent. The likelihood that both events A and B will occur is defined mathematically as being equal to the product of the probabilities of A and B. This is how independent occurrences A and B are expressed mathematically.
Thus, if three independent events happen one after the other, a list of the sample space tools cannot be used.
correct option: A list

8 The cost of a laptop increased by 25% between
2015 and 2019
In 2019. the laptop cost £1000
How much did the laptop cost in 2015?
Given:
The cost of a laptop increased by 25% between 2015 and 2019.
In 2019, the laptop cost £1000.
To find:
The cost of the laptop in 2015.
Solution:
Let x be the cost of the laptop in 2015.
The cost of a laptop increased by 25% between 2015 and 2019. So, the cost of the laptop in 2019 is
Cost of laptop in 2019 = [tex]x+\dfrac{25}{100}x[/tex]
= [tex]x+0.25x[/tex]
= [tex]1.25x[/tex]
In 2019, the laptop cost £1000.
[tex]1.25x=1000[/tex]
[tex]x=\dfrac{1000}{1.25}[/tex]
[tex]x=800[/tex]
Therefore, the cost of the laptop in 2015 is £800.

A store pays $365.84 for a fountain. The store marks up the price by 10%.
What is the amount of the mark-up?
Round your answer to the nearest cent: $
Answer:
The store marks up the fountain by adding $ 36.58 to its original cost, bringing its retail price to $ 402.42.
Step-by-step explanation:
Given that a store pays $ 365.84 for a fountain, and then the store marks up the price by 10%, to determine the amount of the mark-up the following calculation must be performed:
365.84 x 10/100 = X
3,658.4 / 100 = X
36,584 = X
36.584 + 365.84 = 402.424
Thus, the store marks up the fountain by adding $ 36.58 to its original cost, bringing its retail price to $ 402.42.
