Answer:
There are two ways to check if 3x+5=11 is true:
Subtract 5 from both sides of the equation. This will isolate x on the left-hand side of the equation.
3x = 6
Divide both sides of the equation by 3. This will divide both sides of the equation by 3, which will cancel out the 3 on the left-hand side of the equation, leaving x by itself.
x = 2
You can also check if 3x+5=11 is true by plugging in 2 for x. If you do this, you will get 3(2)+5 = 6+5 = 11. Therefore, 3x+5=11 is true when x=2.

Liz's age is two-thirds of Debbie's age. Debbie's age is half of Freya's age. what is the ratio of Liz's age to Freya's age?
Answer:
Let's start by using variables to represent the ages of the three people:
Let L be Liz's age.
Let D be Debbie's age.
Let F be Freya's age.
From the problem, we know that Liz's age is two-thirds of Debbie's age, so we can write:
L = (2/3)D
We also know that Debbie's age is half of Freya's age, so we can write:
D = (1/2)F
To find the ratio of Liz's age to Freya's age, we need to express Liz's age and Freya's age in terms of a common variable. Since we have an equation relating Debbie's age to Freya's age, we can use that as the common variable. From the equation D = (1/2)F, we can solve for F in terms of D:
F = 2D
Now we can substitute this expression for F into the equation for Liz's age:
L = (2/3)D = (2/3)(1/2)F = (1/3)F
So Liz's age is one-third of Freya's age. The ratio of Liz's age to Freya's age is therefore 1:3.

HELP!!! 2(4x+3)=x+1 It's geometry!
Answer:
\(x=-\frac{5}{7}\)
Step-by-step explanation:
\(2(4x+3)=x+1\)
\(8x+6=x+1\)
\(8x-x=1-6\)
\(7x=-5\)
\(x=\frac{-5}{7}\)
Answer:
x = -5/7
Step-by-step explanation:
2(4x+3)=x+1
Distribute
8x +6 = x+1
Subtract x from each side
8x+6-x = x+1-x
7x+6 = 1
Subtract 6 from each side
7x+6-6 = 1-6
7x =-5
Divide each side by 7
7x/7 = -5/7
x = -5/7

The base of this pyramid is a rectangle. How many congruent faces does this pyramid have?
The pyramid has 4 congruent faces.
The pyramid has 5 congruent faces.
The pyramid has 1 pair of congruent faces.
The pyramid has 2 pairs of congruent faces.
Answer: The Pyramid has 2 pairs of congruent faces
Step-by-step explanation:
The explanation of congruent is the face has the same shape and same size. On rectangle pyramid, the height triangle are 2 same faces and 2 same faces, so it has 2 pairs of congruent faces
If there are 2 red balls, 2 blue balls, and 4 green balls in a pail, what is the probability of pulling out a green ball?
(step-to-step pls)
Answer:
Step-by-step explanation:
Step 1 is to find the total number of balls in the pail.
There are 8 balls in total
Now that you know there are 8 balls, you have to find out how many of those 8 are green. This is because you want to pull out a green ball. You would do the same thing for any other colored ball.
Since 4 out of the 8 balls in the pail are green, you can write this as 4/8
The last step is to simplify to get 1/2 which in other terms is 50%.
So the probability of you pulling a green ball is 50%
A recipe calls for 1 3/4 cups of milk for 8 servings. If the recipe is increased to 24 servings, how much cups of milk are needed?
Assuming there is the same amount of cups of milk per serving.
Answer:
\(5~1/4\)
Step-by-step explanation:
When we increase from \(8\) servings to \(24\) servings, we triple the amount of servings needed, and hence we triple the amount of ingredients needed.
So, the amount of cups of milk needed is \(3(1+3/4)=3+9/4=3+2~1/4=5~1/4\).
So, the answer is \(\boxed{5~1/4}\) and we're done!
The number of cups of milk needed for the recipe is 5 1/4 cups.
What is Proportion?Proportions are defined as the concept where two or more ratios are set to be equal to each other.
Suppose we have two ratio p : q and r : s. If both these ratios are proportional, then we can write it as p : q = r : s.
Given that,
A recipe calls for 1 3/4 cups of milk for 8 servings.
We have to find the number of cups of milk needed for 24 servings.
The ratio of the number of cups of milk to the number of servings will be equal.
Let x be the number of cups of milk needed for 24 servings.
1 3/4 cups = 7/4 cups
Using proportion,
7/4 / 8 = x / 24
8x = 7/4 × 24
8x = 42
x = 42 / 8
= 21 / 4
= 5 1/4 cups.
Hence the number of cups needed for 24 servings is 5 1/4 cups.

A. 1/15
B. 1/10
C. 2/5
D. 3/5
Answer: A: 1/15
Step-by-step explanation:
A number cube has 6 sides.
the probability of getting either a 2 or a 3 will be 2/6, (since both events have an equal chance of happening, and they are out of total 6 possible outcomes).
2/6 simplifies to 1/3, so that is the probability of getting either a 2 or a 3
Next, the probability of landing on blue:
it will be 1/5, since there is only 1 blue section out of 5 *equally* divided sections.
Note that the probability includes the word "and". this means that we will use multiplication.
1/3 * 1/5 = 1/15

For each ride, a taxi service charges an initial fee plus an additional fee based on the number of kilometers of the trip. The graph shows the cost for taxi rides. Select a true statement. The rise is 4 while the run is 2. The selection of answers are:
A: The slope is 2.1. This means that each kilometer costs $2.10.
B: The slope is 5. This means that each kilometer costs $5.
C: The y-intercept is 2.1. This means that the initial fee is $2.10.
D: The y-intercept is 5. This means that the ride lasts 5. kilometers.
Which one is right and why?
THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!
The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.
The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.
