Answer:
For the chart, the missing number on top is 10. the bottom numbers are 1.5 then 9.
For the question, all of the numbers equal the ration 5:3.
Question 2: Yes. 30/x=2/4 which equals 60 (minutes) which is an hour.
Step-by-step explanation:
1A:
2.5 amount of water - 1.5 amount of pasta
10 amount water - 6 amount pasta
15 amount water - 9 amount pasta
2.5 : 1.5
5 : 3
10 : 6
15 : 9
1B. these quantities are proportional because they can all be simplified to the same unit rate of 5 : 3.
2. Johnny is correct. The rate is 4 : 2, with a unit rate of 2 : 1. If you multiply both sides by 30 (how many inches deep the hot tub is) you get a ratio of 60 : 30, meaning it would take an hour to fill up the tub.
Find the value of X please help
Solve for x:
2x - 14 = 3x + 6
Answer:
x = - 20Step-by-step explanation:
[tex]2x - 14 = 3x + 6[/tex]
Move 3x to the other side of the equation
[tex]2x - 3x - 14 = 6 \\ - x - 14 = 6[/tex]
Move -14 to the right side of the equation.
[tex] - x = 14 + 6 \\ - x = 20[/tex]
Multiply both sides by - 1
[tex] - ( - x) = - 20 \\ x = - 20[/tex]
We have the final answer as
x = - 20Hope this helps you
Answer: add 14 to both sides of the equation
2x-14=3x+6
2x-14+14=3x+6+14
Simplify
add the numbers
2x-14+14=3x+6+14
2x=3x+6+14
add the numbers
2x=3x+6+14
2x=3x+20
subtract 3x from both sides of the equation
2x=3x+20
2x-3x=3x+20-3x
simplify
Combine like terms
2x-3x=3x+20-3x
-x=3x+20-3x
Combine like terms
-x=3x+20-3x
-x=20
Divided both sides of the equation by the same term
-x=20
-x/-1=20-/-1
Simplify
Cancel terms that are in both the numerator and denominator
-x/-1=20/-1
x=20/-1
Divide the numbers
x=20/-1
x=-20
So the answer is x=-20
Hope this helps... Stay safe and have a great day/night!!! :D

Give an example of an equation that has no solution equation and explain why it is a no solution equation.
Answer:
x = x + 7
Step-by-step explanation:
In this equation, it is saying that x is equal to itself plus something else (7). This equation does not make sense at all because x cannot equal to something that is bigger or smaller than itself. If 7 is added to x, like the right-hand side of the equation, it cannot be equal to x from the left-hand side of the equation, so there is no solution to the value of x in this equation.

Answer:
A) y = -1/2x + 2
Step-by-step explanation:
The line is negative, so you will have a negative slope
The line is crossing the y- axis at 2 so the y- intercept is 2.
Now do rise over run or rise/run
The lines rise is 2 and the run is 4
2/4 = 1/2 and since the line is negative the slope is negative -1/2
y = -1/2x + 2

The length of a rectangle is 5 less than 3 times its width. The perimeter is
78. Find the LENGTH.*
Answer:
The length is 28 and the width is 11
Step-by-step explanation:
To solve this problem, we can make the width as x.
Since the length is 5 less than 3 times the width, it's going to be 3x - 5
So now we've got the length and width, just need to find the perimeter, which is all the sides added up together. They already gave us the perimeter, so we just have to solve the equation:
2(3x - 5) + 2x = 78
6x - 10 + 2x = 78
8x - 10 = 78
8x = 88
x = 11
x = 11, but remember, x is the width, not the length. Since we already found what x is, we just have to plug it into the equation of:
3x - 5
3 × 11 - 5
33 - 5 = 28
Answer: Length = 28 (don't forget to add the unit if there is one)

Lin was looking at the equation 2x−32+4(3x−2462)=14x. She said, “I can tell right away there are no solutions, because on the left side, you will have 2x+12x and a bunch of constants, but you have just 14x on the right side.” Do you agree with Lin?
Answer:
Disagree with Lin: There are no solutions because 12x+2x is equal to 14x, if 14x=14x on both sides, the x variable can be cancelled out since they have the same slope
Step-by-step explanation:
I agree with Lin the system of equation 2x - 32 + 4(3x - 2462) = 14x
has no solution.
What are the three types of solutions for a system of linear equations?If a system of equations only contains two linear equations with two variables, the system's equation can be graphed, the graph will have two straight lines, and the intersection point(s) of those lines will be the system's solution.
There are only three matching forms of solution for a given system of equations because there are only three different ways that two straight lines in the plane can graph.
Given, An equation 2x - 32 + 4(3x - 2462) = 14x.
2x - 32 + 12x - 9848 = 14x.
14x - 9880 = 14x.
So, 14x - 9880 ≠ 14x and has no solution.

Calculate the measure of ∠ PMU and ∠ UPM.
m∠ PMU =
m∠ UPM =
Answer:
you want to find angle PMB to find PMU
180-21-35= 124
so now, you subtract 180-124 to find PMU
180-124= 56
Now, subtract 56 and 62 from 180 to find angle UPM
180-56-62= 62
m< PMU = 56
m<UPM = 62
Step-by-step explanation:
So we know that a triangle adds up to 180 degrees. Take 62+35 and subtract it from 180 to find angle P.
62+35=97
180-97=83
Knowing this you can find the two angles of P. You can subtract this number from 21 to find the unknown angle of P.
83-21=62(angle UPM)
Then do the same steps for finding the M angles
(Left Triangle)
62+62=124
180-124=56
(Right Triangle)
21+35=56
180-56=124
And because M intersects a straight line, the M angles should add up to 180.
56+124=180
Hope This Helps :)
