Answer:
$42.5
Step-by-step explanation:
A pair of sneakers was marked up by 1/4 of its original price
The store was selling it at $170
Therefore the original price that the store paid for the pair of sneakers can be calculated as follows
= 1/4 × 170
= 170/4
= 42.5
Hence the original price of the sneakers was $42.5

A hiker is walking down a mountain. She walked 5978 feet in 17 minutes. In that time she descended 1024 feet feom the top of the mountain. She then walked 3927 feet in 7 minutes. In that time she descended 500 more feet. Express the average rate of change in altitude of the hiker from her starting point to her ending point as unit rate
Answer:
[tex]Average \ rate \ of \ change =[/tex] 63.5 ft/min
Step-by-step explanation:
Given that:
A hiker is walking down a mountain.
For the first case:
She descended 1024 feet from the top of the mountain in 17 minutes after walking for 5978 feet.
For the second case:
She descended 500 more feet from the top of the mountain in 7 minutes after walking for 3927 feet.
Thus; the average rate of change in altitude of the hiker from her starting point to her ending point can be expressed as:
[tex]Average \ rate \ of \ change = \dfrac{h_1 +h_2}{t_1 + t_2}[/tex]
[tex]Average \ rate \ of \ change = \dfrac{1024 +500}{17 + 7}[/tex]
[tex]Average \ rate \ of \ change = \dfrac{1524}{24}[/tex]
[tex]Average \ rate \ of \ change =[/tex] 63.5 ft/min

the sum of two numbers is 181 and their difference is 37.Find the larger of the two integers
Answer:
Larger First number: 109
Second number: 72
Step-by-step explanation:
x + y = 181
x - y = 37
x = 37 + y
(37 + y) + y = 181
37 + y + y = 181
37 + 2y = 181
2y = 144
y = 72
x - y = 37
x - 72 = 37
x = 109
Check:
x + y = 181
109 + 72 = 181
181 = 181
x - y = 37
109 - 72 = 37
37 = 37
Larger number is x = 109

A car travels 50 miles per hour, h. What expression represents the total distance you’ve traveled?
Answer:
d = 50h
Step-by-step explanation:
d = distance , h = hours , 50 miles an hour , so 50h
The expression that represents the total distance traveled is 50h .
What is the meaning of Distance ?Distance is the measure of total movement from one place to another , It is a scalar quantity and can be expressed as m and is not dependent upon the direction of the motion.
It is given that
A car travels 50 miles per hour
expression that represents the total distance traveled = ?
Speed = Distance / Time
Given speed = 50 miles/hour
Let h represents the total time
50 = Distance traveled/h
Distance Traveled = 50 h
Therefore the expression that represents the total distance traveled is 50h .

How do i do solving systems using elimination
Answer:
The elimination method for solving systems of linear equations uses the addition property of equality. You can add the same value to each side of an equation. So if you have a system: x – 6 = −6 and x + y = 8, you can add x + y to the left side of the first equation and add 8 to the right side of the equation.

Decimal form: .3
Fraction form: 3/10
(work shown below, hope this helped!)
Given the function defined in the table below, find the average rate of change, in
simplest form, of the function over the interval 0 < x < 3.
Note: in decimal form, this fraction converts to roughly 34.67
=========================================================
Explanation:
Highlight the rows that have x = 0 and x = 3. Cross out or cover the other two rows up.
The two rows that have x = 0 and x = 3 show y = f(x) = 4 and y = 108 respectively.
So we have the two points (0,4) and (3,108). We need to find the slope of the line through these points to find the average rate of change from x = 0 to x = 3.
Turn to the slope formula
m = (y2-y1)/(x2-x1)
m = (108-4)/(3-0)
m = 104/3
We cannot reduce the fraction further.
Using a calculator,
104/3 = 34.67 approximately
If A = -1 +5n2 + 9 and B = 3 – n, find an expression that equals 2 A – 3B
in standard form.
Answer:
10n² + 3n + 7
Step-by-step explanation:
2A - 3B = 2.( -1 + 5n² + 9) - 3.(3 - n)
= -2 + 10n² + 18 - (9 - 3n)
= 10n² + 16 -9 + 3n
= 10n² + 3n +7
