Answer:
0=0
Step-by-step explanation:
3x- 15=3 (x- 5)
We simplify the equation to the form, which is simple to understand
3x-15=3(x-5)
Reorder the terms in parentheses
3x-15=+(+3x-15)
Remove unnecessary parentheses
+3x-15=+3x-15
We move all terms containing x to the left and all other terms to the right.
+3x-3x=-15+15
We simplify left and right side of the equation.
0x=0
0=0
This equation is an identity, so all real numbers are solutions.

A car initially at rest accelerates at 10ms2. The car’s speed after it has traveled 25 meters is what?
Answer:
22.4 m/s
Step-by-step explanation:
Given:
Δx = 25 m
v₀ = 0 m/s
a = 10 m/s²
Find: v
v² = v₀² + 2aΔx
v² = (0 m/s)² + 2 (10 m/s²) (25 m)
v = 22.4 m/s

the selling price of 12 eggs is equal to the cost price of 15 eggs. find the profit percent
Answer:
I believe it would be 25% profit
Step-by-step explanation:
Answer:
ok first thing multiply 15 by the cost of each egg the amount you'll get will be equal to the 12 eggs he sold then check the original price that each egg is supposed to be sold at and multiply it by 12 then subtract the selling price minus the original price to get your profit so to get percentage profit equals profit over original price * 100%

A graph has age (weeks) on the x-axis, and height (inches) on the y-axis. Points are grouped closely together and increase slightly.
Describe the relationship between the variables.
There is no relationship between the variables.
As the age increases, the height increases.
As the age increases, the height decreases.
As the height decreases, the age decreases.
Answer:
the correct answer is B because if you look at the graph you will see that both are increasing so the answer is as the age increases the height increases

A rectangle is dilated by a scale factor of n = 1. Which statement is true regarding the image of the dilation?
A. The image will be smaller than the pre-image because n = 1.
B. The image will be congruent to the pre-image because n = 1.
C. The image will be larger than the pre-image because n = 1.
D. The image will be a triangle because n = 1.
Answer:
the answer is B
Step-by-step explanation:
A scale factor is defined as the ratio between the scale of a given original object and a new object.
The image will be congruent to the pre-image because n = 1.
Option B is the correct answer.
What is a scale factor?A scale factor is defined as the ratio between the scale of a given original object and a new object.
We have,
A rectangle is dilated by a scale factor of n = 1.
This means that there is no change in the rectangle.
When the pre-image is the same as the image formed the scale factor is one.
The preimage is the original shape.
The image is the final image after dilation.
So,
The image will be congruent to the pre-image because n = 1.
Thus,
The image will be congruent to the pre-image because n = 1.
Option B is the correct answer.

HELP ME Rachel finished a meal at a diner and received a bill for $10.99. She charged the bill along with a 15 percent gratuity to her credit card. What is the total amount she charged to her credit card? $11.14 $12.64 $13.19 $13.73
Answer: $12.64
Step-by-step explanation:
From the question, we are informed that Rachel finished a meal at a diner and received a bill for $10.99 and that she charged the bill along with a 15 percent gratuity to her credit card.
The total amount she charged to her credit card will then be:
= $10.99 + (15% × $10.99)
= $10.99 + (0.15 × $10.99)
= $10.99 + $1.6485
= $12.6385
= $12.64
Ted has two boards. The length of the second board is five inches more than two times the length of the first board. The total length of the two boards is 65 inches.
How many inches long is the first board?
Answer:
Length of the first board is 20 inches.
Step-by-step explanation:
Let the length of first board is x and that of second board is five inches more than two times the length of the first board.
Length of second board = 5+2x
Total length of two boards is 65 inches
ATQ,
x+5+2x=65
3x+5=65
Taking like terms together,
3x=65-5
3x=60
x = 20
So, the length of the first board is 20 inches.
A ladder leans up against a wall and makes a 60 degree angle with the ground. If it reaches 90 ft. up the wall, how long is the ladder? Round to the nearest tenth
Answer:
The length is approximately 103.92 ft
Step-by-step explanation:
The angle the given ladder makes with the ground = 60°
The height to which the ladder reaches. h = 90 ft.
Assumption;
The angle formed between the wall and ground = 90°
The shape formed by the length, l, of the ladder the height to which the ladder reaches on the wall, h, and the ground, b, is a right triangle, with the length, l, of the ladder facing the 90° angle and the height, h, facing the 60° angle.
By sine rule, we have;
l/sin(90°) = h/sin(60°)
Therefore, the length l = sin(90°) × h/sin(60°) = 1 × 90/(sin(60°)) = 90/((√3)/2) = 2 × 90/√3 ≈ 103.92
The length, l ≈ 103.92 ft.

The average person's speed when riding a bike along a street is 18 kilometers per hour. What conversion factor can be used to convert this speed to meters per hour? StartFraction 1 kilometer Over 1,000 meters EndFraction StartFraction 1 meter Over 1,000 kilometers EndFraction StartFraction 1,000 meters Over 1 kilometer EndFraction StartFraction 1,000 kilometers Over 1 meter EndFraction
Answer:
The conversing factor is [tex]\dfrac{1}{1000}\ km[/tex].
Step-by-step explanation:
The average speed of a person is 18 km/h.
We need to convert the speed to meters/hour.
We know that,
1 km = 1000 m
or
[tex]1\ m=\dfrac{1}{1000}\ km[/tex]
So,
[tex]18\ \dfrac{km}{h}=18\times \dfrac{1000\ m}{h}\\\\=18000\ m/h[/tex]
So, the conversing factor is [tex]\dfrac{1}{1000}\ km[/tex].
