Answer:
You need to find the equations for each scenario and set them = to each other
Step-by-step explanation:
A) S = 5t + 5
B) S = 7t + 2
Now set them = and solve for t
5t + 5 = 7t + 2
3 = 2t
t = 3/2 of an hr
To check plug in 3/2 into both equations and you should get same answer.

Question 3 What is the slope of the line that passes through the points (0.-7) and (-4, 3)? 0 -3/11 O -2/5 À O -5/2 0 10/4 Question 4
Answer:
Gradient = Change in y / Change in x
Gradient = (-7-3) / (0-4)
Gradient = -10/-4
Gradient = 2.5
So the answer is 10/4, which is 2.5
The slope of the line passes through the points (0.-7) and (-4, 3) is -5/2. The correct option is B.
What is a slope?Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line. The slope is defined as the ratio of the rise to the run.
Given that the points are (0.-7) and (-4, 3). the slope of the line will be calculated as,
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Slope = ( 3 - (-7) / ( -4 - 0 )
Slope = 10 / -4
Slope = -5 / 2

Lines s, t, and u are perpendicular bisectors of the sides of APGH and meet at J. If JG - 2x+ 2, JH - 2y-4, JF-8 and
HI - 32-3, find x, y, and z.
Ox= 5, y = 2, z = 2
O x = 2, y = 7,2 = 2
x = 3, y = 6,2 = 4
x = 6.) = 3,2 = 4
Answer:
x = 3, y = 6, z = 4
Step-by-step explanation:
If lines s, t, and u are perpendicular bisectors of the sides of APGH and meet at J, then JG = JH = JF = HI
Given
JG - 2x+ 2
JH - 2y-4
JF-8 a
HI - 3z-3,
Hence 2x+2 = 2y-4 = 3z-3 = 8
This means that
2x+2 = 8
2x = 8-2
2x = 6
x = 3
Also, 2y-4 = 8
2y = 8+4
2y = 12
y = 6
And 3z-3 = 8
3z = 8+3
3z = 11
z = 11/3
z = 3.67 ≈ 4
Hence x = 3, y = 6,z = 4

what is the mean of this set
0,100,100,100,100
Answer:
80
Step-by-step explanation:
Mean simply means the average. To calculate the average of all these numbers, add them all up together and divide that number by how many numbers you added.
A simple equation you can use is:
[tex]\frac{the sum of the terms}{the number of terms}[/tex]
To calculate the mean of the set : 0,100,100,100,100
= 0 + 100 + 100 + 100 + 100
= 400 / 5
= 80
The mean of the set is 80.
A plant is already 53 centimeters tall, and it will grow 1 cm every month.
Let H be the plants height (in centimeters) after M months.
Write an equation relating H to M. Then use this equation to find the plant height after 26 months.
Equation: h = 53 + 1m
Solving for m = 26: h = 79
The plant will be 79cm tall after 26 months
The height of the plant, H, is related to the number of months, M, by the equation H = M + 53. The plant will be 79 centimeters tall after 26 months.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
The height of the plant, H, is related to the number of months, M, by the equation H = M + 53.
This equation represents the plant's initial height of 53 centimeters plus the additional height it will grow each month.
To find the plant's height after 26 months, we can substitute M = 26 into the equation:
H = M + 53
H = 26 + 53
H = 79 cm
So, the plant will be 79 centimeters tall after 26 months.

Another neighbor said, “My age is the difference between twice my age in 5 years and and twice my age 5 years ago.” How old is this neighbor? A third neighbor had the same claim for 17 years from now and 17 years ago. How old is this neighbor?
Answer:
The neighbor is 20 years old.
The third neighbor is 68 years old.
Step-by-step explanation:
Equations
Let's set:
x=current age of the neighbor
x+5=his age in 5 years
x-5=his age 5 years ago
He claims that his age is the difference between twice his age in 5 years and twice his age 5 years ago. Then:
x = 2( x + 5 ) - 2( x - 5 )
Operating:
x = 2x + 10 - 2x +10
Simplifying:
x = 20
The neighbor is 20 years old.
Repeating for the other neighbor, a similar equation is established:
x = 2( x + 17 ) - 2( x - 17 )
Operating:
x = 2x + 34 - 2x +34
Simplifying:
x = 68
The third neighbor is 68 years old.

how many hundredths are in 11 wholes?
how many hundredths are in 3 tenths?
how many hundredths are in 11.3?
pls help!!!
Answer:
1) 11/100 or 0.11
2) 3/1000 or 0.003
3) 113/1000 0.113
Step-by-step explanation:
Firstly, hundredths is the same as 1/100.
Multiply every number by 1/100.
11/1 • 1/100 = 11/100 or 0.11
(Remember, 11 over 1 is the same as 1. Multiply the numerators and denominators and you get 11/100).
3/10 • 1/100 = 3/1000 or 0.003
11.3/1 • 1/100 = 113/1000 or 0.113
(Move the decimal once to the right to get rid of the decimal point).

You reverse the inequality symbol when you multiply or divide both sides of an inequality by the same negative number.
True or false?
Step-by-step explanation:
The statement is true, because when we multiply or divide both sides of an inequality by the same negative number we reverse the inequality symbol.
What is Inequality?A relation by which we can compare two or more mathematical expression is called an inequality.
Let an example of the inequality as;
⇒ 2x < 3
Multiply by - 1, we get;
⇒ - 2x > - 3
Thus, When we multiply or divide both sides of an inequality by the same negative number we reverse the inequality symbol.
