The diagram shows a square.
(7x + 3)cm (5x + 8) cm
Find the length of the side of the square.
Answer:
x = 5/2cm
Step-by-step explanation:
Because this is a square and each side is equal to each other in length, we can say:
7x + 3 = 5x + 8
We can start rearranging this equation to collect like terms:
7x = 5x + 8 - 3
7x = 5x + 5
7x - 5x = 5
2x = 5
x = 5/2
We can test this out by substituting our new found value for x into the original equation:
7 * (5/2) + 3 = 5 * (5/2) + 8
(35/2) + 3 = (25/2) + 8
I'm going to change the integers (3 and 8) to fractions so the arithmetic is easier, as they'll all have the same denominator.
(35/2) + (6/2) = (25/2) + (16/2)
(41/2) = (41/2)
So as you can see above, with x = 5/2, both sides are equal.
You don't need to put the fractions in brackets; I just do that to make it look a little less messy.
Also, I've only included the units (cm) in the answer. I don't like using units when doing calculations, but your teacher may ask you to perform the calculations using the units throughout.
Ricky's heartbeat is 70 beat per minute. How many days have elapsed if his
heart beat a total of 504,000?
The number of days passed to have an accumulated heartbeat of 504,000 is the ratio of the total heartbeat and the number of beat per minute ; Hence, the number of days is 5 days
Heart beat rate per minute = 70 beats Total number of beats = 504,000Number of heartbeats per day = 70 × (24 × 60) = 100,800 beats
Number of days = (504,000) ÷ (100,800) = 5days
Therefore, the Number of days elapsed is 5 days.

12 workers build a wall in 10hours. How long do 5 workers build a wall
Answer:
24 hours
Step-by-step explanation:
If 12 workers take 10 hours to build a wall, assuming they build at the same rate, it would take one worker 120 hours to build a wall.
By this logic, it would take 120/5 or 24 hours for 5 workers to build a wall
The number of hours 5 men take with the same rate of 12 workers taking 10 hours will be 24 hours.
What is the rate of change?The rate of change is the change of a quantity over 1 unit of another quantity.
Most of the time the rate of change is the change with respect to time.
For example the speed 3meter/second.
The number of hours 1 person take to build the wall = 12 x 10 = 120 hour
Number of men = 5
The number of 5 men will take as 120/5 = 24 hour
Hence "The number of hours 5 men take with the same rate of 12 workers taking 10 hours will be 24 hours".

The points (0, 3) and (1, 9) fall on a particular line. What is its equation in slope-intercept form?
Answer:
y = 6x + 3
Step-by-step explanation:
y2 - y1 / x2 - x1
9 - 3 / 1 - 0
6/1
= 6
y = 6x + b
3 = 6(0) + b
3 = 0 + b
3 = b
Answer:
y = 6x+3
Step-by-step explanation:
[tex]\frac{y2-y1}{x2-x1}\\\\= \frac{9-3}{1-0}\\\\= \frac{6}{1}\\\\= 6[/tex]
Hence, the slope is 6.
Substituting the slope value to the equation 'y=mx+c',
y = 6x +c
Substituting (0,3):
3 = 0 + c
c = 3
Hence,
y = 6x + 3

Mario volunteers 1 day each month at the animal shelter. For y days he cleans for 5.5 hours each day. On the other days he walks dogs for 75 minutes.
Part A. Write an expression for the total number of minutes Mario volunteers each year at the animal shelter.
Part B. Simplify the expression.
Enter the correct answers in the boxes.
A. Expression:
B. Simplified form:
Part A: The expression for the total number of minutes Mario volunteers each year at the animal shelter = (405/y) x 365
Part B: The simplified form of the expression for the total number of minutes Mario volunteers each year at the animal shelter = (147825/y) minutes
Number of days Mario volunteers each month at the animal shelter = 1
Number of hours Mario cleans for y days = 5.5 hours
Number of hours Mario each day = 5.5/y
Number of minutes Mario uses to walk dogs for y days = 75 minutes
Number of hours Mario uses to walk dogs for y days= 75/60
Number of hours Mario uses to walk dogs for y days= 1.25 hours
Number of hours Mario uses to walk dogs each day= 1.25/y
Total number of hours Mario volunteers in a day = Number of hours Mario cleans each day + Number of hours Mario uses to walk dogs
Total number of hours Mario volunteers in a day = 5.5/y + 1.25/y
Total number of hours Mario volunteers in a day = 6.75/y
Convert the number of hours to minutes
1 hour = 60 minutes
Total number of minutes Mario volunteers in a day = (6.75/y) x 60
Total number of minutes Mario volunteers in a day = (405/y) minutes
Number of days in 1 year = 365
The expression for the total number of minutes Mario volunteers each year at the animal shelter = (405/y) x 365
The simplified form of the expression for the total number of minutes Mario volunteers each year at the animal shelter = (147825/y) minutes

D) 5 6 yard
Answer:
5/8 yards

Amount Used: 3/8 yard
Amount Remaining : 1/4
Amount started with = Amount Used + Amount Remaining
We need to find the common denominator for 8 and 4.
3/8 stays 3/8, and 1/4 becomes 2/8 (multiply the numerator and
denominator of 1/4 by 2)

Sorry that this is long, but hopefully this has the answers and explanations you are looking for. Have a nice day!
1a: P' (0, 1) Q' (9, 7)
First, we will look at point P. It is at (-7, -2). If we move it up three and right 7, we will do (-7 +7, -2 +3) which gives us (0, 1). We do the same for Q, (2, 4) -> (2+7, 4 +3) = (9, 7)
2a: This transformation represents the point being moved down 5 units and to the right 2 units. X is left/right and it's being moved positive two, hence right 2. Y is up/down, and it's being moved negative 5, hence down 5.
2b: (4, -3) (not 100% sure on this one)
The wording slightly confused me, but if it's talking about having point A be apart of 2a, here is what we do:
(2, 2) -> (2 + 2, 2 - 5) -> (4, -3)
3a: (x - 26, y + 17)
So (in the y) -13 becomes 4, so it moves 17 units up. For the x, -2 becomes -28, so it is moved 26 units down. This becomes x - 26 and y + 17, which is written correctly above.
3b: A. AP and A'P' have different locations
For a translation shape, size, and direction doesn't change, just where it's at (location).

Here are two points from line AB: A (9,-2) B(1, 14) Here are two points from line CD: C (6.-10) D (8,-14) Are these lines parallel, perpendicular or neither?
Step-by-step explanation:
slope of AB = y2 -y1/x2 -x1 =14 -(-2)/1-9
= 14 +2 /1 -9
= 16/-8
= -2
slope of CD = -14 -(-10)/8 -6 = -14 +10 /2
-4/2 = -2
since slope of AB = CD
