Joshua after all his spending has $7.75 at the end of the month
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Let, The savings and his work be denoted by a positive amount and his spending be donated by a negative amount.
So, From the information given his savings of $20.50 and his work of mowing the lawn for $7.50 and washing a car for $3.75 should be added which is,
= $(20.50 + 7.50 + 3.75).
= $31.75
Now, we'll subtract all his spending,
= $(31.75 - 5.25 18.75).
= $7.75.

Steph bought a used bicycle ,restored it and then marked it up by 1/4 of the price she paid. later, she sold it for the marked up price to $80 how much in dollars did steph pay for the bicycle?
Answer:
$ 64
Step-by-step explanation:
Let Steph paid $x to buy the used bicycle.
After restoring, she marked it up by 1/4 of the price she paid.
So, the marked price [tex]= x +\frac 1 4 x = \frac {5x}{4}[/tex]
As she sold the bicycle for the marked up price to $80.
So, [tex]\frac {5x}{4} = 80[/tex]
[tex]\Rightarrow x = \frac {80\times 4}{5}\\\\\Rightarrow x = 64.[/tex]
Hence, she paid $ 64 for the bicycle.

How to simply a fraction
Answer:
In order to simplify a fraction there must be:
1. A number that will divide evenly into both the numerator and denominator so it can be reduced, or.
2. The numerator must be greater than the denominator, (an improper fraction), so it can be converted to a mixed number.
Answer:
To simply a fraction, you need to find the largest number that can go in to both the numerator and denominator. For example, 12/16, the largest number that can go into both it 4. Then divide the numerator and denominator by the large number which would be 3/4

What are the three ways we can write ratios
Answer:
Step-by-step explanation:
The most common way to write a ratio is as a fraction, 3/6. We could also write it using the word "to," as "3 to 6." Finally, we could write this ratio using a colon between the two numbers, 3:6. Be sure you understand that these are all ways to write the same number.
Three ways to write Ratios are : in form of fraction, in form of decimals. Consecutively, they can also be written in form of percentage.
Ratio is an ordered pair of numbers a & b , a : b , where b ≠ 0. It can be written in above mentioned 3 other forms
Considering example is 4 : 8
It can be represented in form of fraction 4 / 8 , that can further be reduced to 1 / 2 It can also be written in form of decimal, 1 / 2 = 0.5 It can also be written in form of percentage, 4/8 = 1/2 = 0.5 = 50%To learn more, refer https://brainly.com/question/13419413?referrer=searchResults

Ed is on a road trip. He has already traveled 211 miles and is driving at a rate of 63 miles per hour. Which equation could be used to find how many hours, x, Ed has left in his road trip if he is traveling 638 total miles? A. 211x + 638 = 63 B. 211x + 63 = 638 C. 63x + 211 = 638 D. 63x + 638 = 211
Answer:
Option C is correct.
Step-by-step explanation:
Distance already traveled by Ed [tex]=211[/tex] miles
Also, Ed is driving at a rate of 63 miles per hour.
Distance [tex]=[/tex] Speed × Time
Distance traveled by Ed in [tex]x[/tex] hours [tex]=63x[/tex]
Total distance traveled by Ed [tex]=211+63x[/tex]
Also, total distance traveled by Ed is [tex]638[/tex] miles.
Therefore,

Type your answer
SUBMIT
Answer:
5 Drop Cloths
Step-by-step explanation:1 - Find the areas of both the room and the drop cloth
Drop Cloth:
A = L x W
A = 8 x 16
A = 48
Room:
A = L x W
A = 14 x 16
A = 224
2 - Divide the area of the room by the area of 1 drop cloth
This is to see how many times the area of the drop cloth will go into the area of the room
Room Area/Drop Cloth Area =
224/48 = 4.66666666... = 5 drop cloths

How are x and y intercepts alike and different?
Answer:
x and y intercepts are alike because they both cross each other, they are different because the Y axis is vertical while the X axis is horizontal.
The similarities between [x] - intercept and [y] - intercept is discussed below.
What is the general equation of a Straight line?
The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written as -
Ax + By + C = 0
By = - Ax - C
y = (- A/B)x - (C/A)
We have [x] and [y] intercepts of a straight line.
The [y] - intercept is the line where the line cuts the [y] - axis whereas [x] - intercept is the line where the line cuts the [x] - axis.[y] - intercept has coordinates (0, y) and [x] - intercept has coordinates (x, 0).We can calculate the slope of the line using the [y] - intercept and the [x] - intercept as -m = (0 - y)/(x - 0)
m = - y/x
Therefore, the similarities between [x] - intercept and [y] - intercept is discussed above.

6. Challenge Problem: One owl hoots every 3 hours, a second owl hoots every 8 hours, and
a third owl hoots every 12 hours. If they all hoot together at the start, how many times
during the next 80 hours will just two of the owls hoot together?
Answer:
9 times
Step-by-step explanation:
The least common multiple (henceforth written as LCM) of 3 and 8 is 24. Therefore, these 2 owls hoot 72/24 = 3 times. The LCM of 3 and 12 is 12. These 2 owls hoot 72/12 = 6 times. The LCM of 8 and 12 is 24. These 2 owls hoot 72/24 = 3 times. Altogether, these owls hoot the LCM of 3, 8, AND 12, or 72/24 = 3 times. 3+3+6-3 = 9 times.
If they all hoot together at the start, 9 times during the next 80 hours will just two of the owls hoot together.
What is number theory?Number theory is the study of integers and functions of arithmetic.
One owl hoots every 3 hours.
Second owl hoots every 8 hours.
Third owl hoots every 12 hours.
If they all hoot together at the start, how many times during the next 80 hours will just two of the owls hoot together
Number theory indicates that the multiples of the periods of hooting are;
The multiples of 3 are; 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, 51, 54, 57, 60, 63, 66, 69, 72,75, 78, 81, 82
The multiples of 8 are; 8, 16, 24, 32, 40, 48, 56, 64, 72, 80
The multiples of 12 are; 12, 24, 36, 48, 60, 72,
The least common multiple of 3 and 8 is 24, these 2 owls hoot 72/24 = 3 times.
The LCM of 3 and 12 is 12, these 2 owls hoot 72/12 = 6 times.
The LCM of 8 and 12 is 24, these 2 owls hoot 72/24 = 3 times.
Altogether, these owls hoot the LCM of 3, 8, AND 12, or 72/24 = 3 times. 3+3+6-3 = 9 times.
Therefore, 9 times during the next 80 hours will just two of the owls hoot together.
