here is an inequality: 2x+5>50. explain the steps you would use to solve the inequality for x. what would the graph look like
Answer:
Step-by-step explanation: 2 plus 5
7 <50
Answer:
x = 22.5
Step-by-step explanation:
2x + 5 > 50.
We do inverse operations sooo:
2x + 5 - 5 > 50 - 5.
50 - 5 = 45.
Then we do 2x ÷ 2 and 45 ÷ 2.
45 ÷ 2 = 22.5.
To check our answer to see if its right we do 22.5 x 2 which equals 45. Then we do 45 + 5 which equals 50. So the sign is wrong it should be greater than or equal to.

Answer:
edc≡80°
cba=32.75°
Step-by-step explanation:
A triangle is 180° so for edc you do 180-100= 80°. For cba you do
180-49= 131. Then to get x you do 131÷4= 32.75°

solve the proportion. where necessary, round to the nearest hundredth. 8/2 = x+3/4
Answer:
x = 13
Step-by-step explanation:
8/2 = (x + 3)/4
~Simplify
4 = (x + 3)/4
~Multiply 4 to both sides
16 = x + 3
~Subtract 3 to both sides
13 = x

2x+10=2(x-5)
-2(x+5)=2x-10)
-2x-10=-2(x+5)
-2(x-5)=-2x-10
Answer:
The answer would be D I believe.
Step-by-step explanation:
The -2's and the x = 2 so they should be equivalent. But I dont know :/
Answer:
The answer would be C
Step-by-step explanation:
C is the only one that have the same numbers on both sides.
A would be 2x+10=2x-10
B would be -2x-10=2x-10
C would be -2x-10=-2x-10
D would be -2x+10=2x-10
Ross has a model truck. It has a scale of 1 inch for every 32 inches on a real-sized truck. He wants to build a garage for the model at the same scale.
Given that the garage for a real-sized truck is 12 feet wide, how wide should his model garage be?
Answer in decimal form: 4.5 inches
Answer as a mixed number = 4 & 1/2 inches
========================================================
Explanation:
" It has a scale of 1 inch for every 32 inches on a real-sized truck" means the the scale is 1:32
Put another way, the real life width is 32 times greater than the scale model.
So we can form the equation
y = 32x
where x is the scale model width and y is the actual real life width.
---------
The garage in the real world is 12 feet wide, or 12*12 = 144 inches wide.
Plug y = 144 into the equation and solve for x
y = 32x
32x = y
32x = 144
x = 144/32
x = 4.5
His scale model garage must be 4.5 inches wide
4.5 inches = 4 & 1/2 inches = 4 and a half inches
Answer:
4.5 inches
Step-by-step explanation:
First, convert all measurements to the mase units
12 feet -> 144 in
Now, we will identify what 144 inches would be as a model scale. We will do so by dividing 144/32 since 32inches equals 1 model scale inch.
144/32= 4.5
therefore, the garage will be 4.5 inches as a model scale.
Find the value of x in each case.

an arts academy requires there to be 3 teachers for every 51 students and 5 tutors for every 45 students. how many students does the academy have per teacher? per tutor? how many tutors does the academy need if it has 90 students? The academy has ___ students per tutor
Answer:
17 students per teacher, 9 students per tutor. You need 10 tutors if the school had 90 students.
Step-by-step explanation:
51 students divided by 3 teachers = 17 students per teacher.
45 students divided by 5 tutors = 9 students per teacher.
If there are 9 students per tutor 9 * 10 = 90 so ten tutors

2. A jet plane can carry up to 200,000 liters of fuel. It used 130,000 liters of fuel during a flight. What percentage of the fuel capacity did it use on this flight?
Answer:
1. 20 (.8) = 16
It takes him 16 minutes to walk to school.
This is because 80% as a decimal is .8 and you multiply that by how long it takes Person A to walk and you get 16.
2. 65%

"Is there only one way to break up a 2-digit number into tens and ones? Explain."
Yes, to break a 2-digit number into tens and ones it is a simple process. To do it you have to take a number, let's say, 56. We can take the 5, because it has one digit to the right of it, we add one 0 to the right of it. Then we do the 6, which has nothing to the right, so we don't put anything there. 50 and 6. 5 tens and 6 ones.
I'm pretty sure that's the only way. If anyone knows otherwise, please post in the comments.

A bicycle wheel on the scale model is 2 inches in diameter, while in the actual machine, it will be 28 inches in diameter.
Question 1
Part A
Based on the measures of the wheel diameter, what is the unit rate of inches of machine per inch of the model?
Answer:
The unit rate is 16
Step-by-step explanation:
The unit rate of the machine is given as 14 inches per model.
What is Unitary method?In order to solve a problem for two different values of a quantity, its unit value is first derived. This method is known as unitary method.
Given that,
The diameter of bicycle wheel on the scale model is 2 inch.
And, the diameter in actual machine is 28 inch.
The unit rate of the machine can be found by using unitary method as follows,
For 2 inch diameter on scale model, diameter in machine = 28 inch
For 1 inch diameter on scale model, diameter in machine = 28/2 inch
= 14 inch.
Hence, the unit rate of inches of machine per inch of the model is 14 inches per model.
