the subtraction property of equality
Step-by-step explanation:
Given
8x + 15 = 11x + 2
Subtract 15 from both sides of the equation
8x + 15 - 15 = 11x + 2 - 15
8x = 11x - 13
Answer:
the addition property of equality
Step-by-step explanation:
Compare step 1 with step 2 in the solution process:
step 1: -5x = -4x - 15
step 2: -x = -15
The variable was isolated on the left side of the equation by adding 4x to both sides. This is justified by the addition property of equality.

Between the time Iko woke up and lunchtime, the temperature rose by 11 degrees. Then by the time he went to bed, the temperature dropped by 14 degrees.
Write an addition expression for the temperature relative to when Iko woke up.
Answer:
[tex]T_t=x\textdegree-3\textdegree[/tex]
Step-by-step explanation:
let x° be temperature when he woke up. Given that the temperature rose by 11° then later dropped by 14°. Also let [tex]T_t[/tex] be temperature at time t The temperature relative to time of waking up can be expressed as:
[tex]T_t=x\textdegree \pm \bigtriangleup T\textdegree\\\\T_t=x\textdegree + 11\textdegree -14\textdegree\\\\T_t=x\textdegree-3\textdegree[/tex]
Hence, temperature relative to time of waking up is expressed as
[tex]T_t=x\textdegree-3\textdegree[/tex]

1. Mrs. Brown had $16 dollars in her
wallet. After shopping at the store, she
now has $8. How much money did
Mrs. Brown spend at the store?
Final answer:
Mrs. Brown spent $8 at the store, which is found by subtracting her remaining amount of $8 from her initial amount of $16.
Explanation:
The amount of money Mrs. Brown spent at the store can be calculated by subtracting the amount she had after shopping from the amount she had before going to the store. Mrs. Brown had $16 before shopping and was left with $8 after shopping. Therefore, to calculate how much money she spent, we would perform the following subtraction:
$16 (before shopping) - $8 (after shopping) = $8 (spent)
Hence, Mrs. Brown spent $8 at the store.
Sheila went to the fair and spent a total of $40. She paid $16 for a ticket to the fair, and she played some games at the fair for $3 each. Which equation could be used to determine the number of games, x, Sheila played?

Deion Sanders can run the 40 yard dash in 4.19 seconds. At this rate, how long would it take him to run a mile?
**hint** There are 1760 yards in a mile.
Approximately 3:07 minutes Approximately 184.36 minutes Approximately 420 seconds Approximately 7 minutes
Answer:
184.36
Step-by-step explanation:
If you times 40×45=1760 so you have to times 4.19×44= The answer/ 184.36
Deion Sanders would approximately take 3 minutes and 7 seconds to run a mile at his 40 yard dash pace of 4.19 seconds, calculating his speed and using the number of yards in a mile to find the total time needed.
To calculate the time it would take Deion Sanders to run a mile at his 40 yard dash pace, we first determine his speed over that distance. We know he runs 40 yards in 4.19 seconds, so we can calculate his speed as follows:
Speed = distance / time
Speed = 40 yards / 4.19 seconds
Speed = 9.55 yards/second (approximately)
Since there are 1760 yards in a mile, to find out how long it will take to run a mile, we divide the total yards in a mile by the speed:
Time to run a mile = distance / speed
Time to run a mile = 1760 yards / 9.55 yards/second
Time to run a mile = 184.293 seconds (approximately)
Converting seconds to minutes yields approximately:
184.293 seconds = 3.07155 minutes (184.293 seconds / 60 seconds per minute)
This result shows that at Deion Sanders' 40 yard dash speed, it would take him approximately 3 minutes and 7 seconds to run a mile.

How do u find the density of a sphere
Answer:
Step-by-step explanation:
The formula to find density of a sphere is mass/volume.
Density in simple words means the relation between weight and size of a substance. It is basically related to the compactness of a substance.It is a very useful characteristic and every material has density.
To calculate density, we must calculate the mass and volume of the substance.
p=m/v
where p= density, m= mass of substance, v= volume of substance
Formula to calculate the volume of a sphere = 4/3 [tex]\pi r^{3} \\[/tex]
Therefore, density p =[tex]m/4/3\pi r^{3}[/tex]

width = 12.1
equation : P = 4w + 4.6
Answer:
The width of the rectangle is 12.1 meters
Step-by-step explanation:
Step 1: Find the width
2w + 2(w + 2.3) = 53
2w + 2w + 4.6 = 53
Step 2: Combine like terms
2w + 2w + 4.6 = 53
4w + 4.6 = 53
Step 3: Subtract 4.6 from both sides
4w + 4.6 - 4.6 = 53 - 4.6
4w = 48.4
Step 4: Divide both sides by 4
4w / 4 = 48.4 / 4
w = 12.1
Answer: The width of the rectangle is 12.1 meters

To calculate the area of the park not occupied by the pond, first compute the total area of the park as (6x + 2)(3x + 7). Then subtract the area of the square pond, 64 sq. ft, to get the final expression for the unoccupied park area: (6x + 2)(3x + 7) - 64.
Explanation:The subject of this question is Algebra, specifically forming an expression for the area of a rectangle and subtracting the area of a square. First, calculate the total area of the rectangular park. The area of a rectangle is given by the product of its length and width. So, the total area of the park is (6x + 2)(3x + 7).
Second, find the area of the turtle pond. Since it's a square with a side length of 8ft, its area is 8*8 = 64 sq. ft.
Finally, to find the area of the park that is not occupied by the turtle pond, subtract the area of the pond from the total park area. So, the final expression is (6x + 2)(3x + 7) - 64.

K/6 = 15/18
Solve the proportion
Answer:
k = 5
Step-by-step explanation:
Step 1: Cross multiply
k/6 = 15/18
k(18) = 6(15)
18k = 90
Step 2: Divide both sides by 18
18k / 18 = 90 / 18
k = 5
Answer: k = 5
Another way to do it is to multiply both sides by 6
k/6 * 6 = 15/18 * 6
k = 90 / 18
k = 5
Answer: 5
Step-by-step explanation: To solve for k in the given proportion, we use the means-extremes property. The product of the extremes, (k)(18), equals the product of the means, (6)(15).
So we have (k)(18) or 18k = (6)(15) or 90.
Now we have the equation 18k = 90.
Dividing both sides by 18, k = 5.
It's a good idea to check the answer in these types of problems so if we plug a 5 back in for k in the original proportion, we have [tex]\frac{(5)}{6}= \frac{15}{18}[/tex] which is a true statement since 15/18 reduces to 5/6.
