Answer: x=2.5, and x-1=1.5
Step-by-step explanation:
x + 3 = 3x - 1
(-x)= 3 = 2x - 1
(÷2) = 1.5 = x - 1
(+1)= 2.5 = x
Find the measure of the missing angle.

Answer:
a = 38 degrees
Step-by-step explanation:
ok that line is equal to 180 degrees
180 of the line subtract 52 degrees and 90 degrees equal the missing angle
52 + 90 = 142
180 - 142 = 38
a = 38
8x-3y=3
2x+y=-15

HELP PLEASE HELP <3......
For this question, you want to look at the equation and find a number with a variable.
For y = 2x + 3, 2x is the thing you should be looking at.
For the slope, you need to take out the x in 2x to find the answer. So, 2 should be your answer!
Find the mode and the mean of the following set showing number of hours of operating life 25 flashlight batteries:20, 21, 19, 22 , 18 , 23 , 25 , 22 , 23 , 20 , 23 , 20 , 22 , 21 , 24 , 21, 22 , 23 , 19, 21, 22 , 22 , 24 , 26 , 22.
Answer:
mode: 22
mean: 21
Step-by-step explanation:
For mode, look for the number that occurs the most (22). I remember this because MODE kinda sounds like MOST. Remember that the mean is just another word for average. I remember this because I think its MEAN that they'd make another word for average, although the term average is way easier to remember. So, add all numbers (525) and divide them by 25.
525 divided by 25= 21
(it might be safe to double check my work)
The mean of the set showing number of hours of operating life 25 flashlight batteries is, 21.8
The mode of the set showing number of hours of operating life 25 flashlight batteries is, 22
What is Addition?The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.
Given that;
The set showing number of hours of operating life 25 flashlight batteries is,
⇒ 20, 21, 19, 22 , 18 , 23 , 25 , 22 , 23 , 20 , 23 , 20 , 22 , 21 , 24 , 21, 22 , 23 , 19, 21, 22 , 22 , 24 , 26 , 22.
Now, We can arrange the numbers in ascending order as;
⇒ 18, 19, 19, 20, 20, 20, 21, 21, 21, 21, 22, 22, 22, 22, 22, 22, 22, 23, 23, 23, 23, 24, 24, 25, 26
Thus, The mean of the set is,
⇒ Mean = 18 + 19 + 19 + 20 + 20 + 20 + 21 + 21 + 21 + 21 + 22 + 22 + 22 + 22 + 22 + 22 + 22 + 23 + 23 + 23 + 23 + 24 + 24 + 25 + 26 / 25
⇒ Mean = 545 / 25
⇒ Mean = 21.8
And, The mode of the data set is the most often number in data set.
Hence, The mode of the set = 22

Mr Ramos is going to build a square-shaped room onto his house. Mr. Ramos wants the room's length to be as close to 10 ft as possible. Which area should his room have to give him the side length closest to 10?
Answer:
100ft²
Step-by-step explanation:
The problem here is to find the area of the room that will give a length of 10ft.
Note;
The room is a square room.
Now let us solve this problem;
Area of a square is:
Area = L²
Where L is the length of the room;
So the area of the room is;
Area = 10² = 100ft²
The area of the room that will give a length of 10ft is 100ft²

Which graph best describes the following situation?
Matt was standing 3 feet from the edge of the pool. He walked away from the pool for 4 seconds. Then he was
12 feet away from the edge of the pool.
Answer:
Suppose that P(t) describes the position of Matt over time
Let's define the edge of the pool as our zero in the position axis.
At the beginning, Matt was 3 ft away from the edge, so we have:
P(0s) = 3ft
He walked away for 4 seconds, then he was 12 ft away from the edge.
Then at t = 4s his position was:
P(4s) = 12ft.
So we have two points, (0s, 3ft) and (4s, 12ft).
The graph that describes this situation will be the line that connects those two points.
An example is shown below.

13. There are 48 passengers on a transit bus. At the next stop, 16 passengers got off and 12 others got on the bus.
a) What is the ratio of the passengers who got off the bus compared to the original number on the bus? Show the ratio in lowest terms.
b) What is the ratio of the passengers who got on the bus at the stop compared to the new total then on the bus?
Answer:
a) 1/3
b) 12/44
Step-by-step explanation:
To find the answer to a you must simplify the fraction 16/48 which would give you 1/3.
To find the answer to b you must first subtract 16 from 48 and then add 12. You should get 44 so your ratio of passengers who got on the bus at the stop compared to the new total then on the bus would be 12/44.
Simplify the expression.

Juan read 300 pages in 5 days and Jose read 150 pages in 3 days are these reading rates equivalent
Answer:
No, they aren't equivalent.
Step-by-step explanation:
First divide 300 by 5 to figure out how many pages he read in each day.
That would be 60 pages each day.
Then, divide 150 by 3.
That would be 50.
Since 60 ≠ 50, the reading rates are not equivalent.

Let n be equal to 156% of 70. Which of the following proportions is true?
Answer:
156/100=n/70
Step-by-step explanation:
1.56/70=109.2
156/100=1.56
109.2/70=1.56
as far as im concerned 1.56 and 1.56 is equal lol
The true property is (156/100) = (n/70).
What is the percentage?The percentage is a ratio that can be expressed as a fraction of 100.
Given that n is equal to 156% of 70
n=156% of 70
n=156% × 70
n= (156/100) × 70
(n/70) = (156/100)
Or, (156/100) = (n/70)
Hence, the true property is (156/100) = (n/70).

In the 2011 New York City Marathon, 29,867 men finished the race, and 16,928 women finished the race. Each finisher was given a t-shirt. About how many men's shirts were given away? About how many women's shirts were given away? Explain how you found your answers.
Answer:
About 30000 men
About 17000 women
Step-by-step explanation:
This question has to deal with approximation.
We have:
[tex]Men = 29867[/tex]
[tex]Women =16928[/tex]
To get the required answer, we have to approximate the given parameters.
For men, we have:
[tex]Men = 29867[/tex]
[tex]Men =30000[/tex] -- Approximated
For women, we have:
[tex]Women =16928[/tex]
[tex]Women = 17000[/tex] -- Approximated
This implies that about 30000 men and 17000 men received the t shirts

what is the equation of the line in standard form through each point? (3,1) & perpendicular to -4c + y - 1= 0
help me answer this question in the picture :)))
Answer:
x = 15p
-75
Explanation:
remove brackets:
4px + 4 = 64
solving for x --> 4px = 64 - 4 then--> 4px = 60
then diving both sides by 4p --> x = 60\4p --> x = 15p
now solving for x when p is -5
we will substitute the -5 in the equation we got --> x= 15 (-5)
which will give us --> x = -75
