A recipe calls for 3 cups of orange juice for every 4 cups of fruit punch. If a person makes a large batch of this recipe, how many cups of fruit punch will be needed if 12 cups of orange juice are used? Create a ratio table to solve.
Answers
Since now the cups of orange juice ratio has been altered, the cups of fruit punch ratio needs to be equally altered as well.
12/3 = 4
4(4) = 16
Now that they are equally altered, the new ratio would be 12:16
The number of cups of fruit punch will be equal to 16.
What are ratios and proportions?An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.
Given that a recipe calls for 3 cups of orange juice for every 4 cups of fruit punch. For 12 cups of orange juice.
Since now the cups of orange juice ratio has been altered, the cups of fruit punch ratio needs to be equally altered as well.
(3 / 4) = ( 12 / x)
x = 48 / 3
x = 16
Now that they are equally altered, the new ratio would be 12:16.
Therefore, the number of cups of fruit punch will be equal to 16.

Answer:
PQ=30
Step-by-step explanation:
Knowing that the segment has 3 parts that are 3:1:1 and sum up to 50, you could find how much 1 would equal by finding the total in relation to the ratio (doing 3+1+1) which gets you 5 parts. Then you can divide the total (50) by 5 to figure out how much one part would equal (10). Now, since you know that 1 part is equal to 10 and that PQ is 3 parts, you can find that PQ is equal to 3x10, or 30.
explain why 3(5x) does not equal to (3 times 5)(3times x)
Answers
Answer:
Because 3(5x) is the same as 3 *5 * x
Step-by-step explanation:
When a number is next to another in parantheses, it signifies multiplication. In this case, we already have 5 and x grouped together by a multiplication sign, so the entire thing is 5 * x. The statement below is key
Distribution in multiplication is only possible if a variable is grouped to another real number by a plus or minus sign.
So in this case, we have 3 * 5 * x, which is 15x. However, if we had 3(5 + x), we would have 15 (3 * 5) + 3x (3 * x).
Hopefully that makes sense!

Answer:
A. 3
B. 4.5
Explanation:
A. 2(5x - 3) = 24
10x - 6 = 24
then add six on both sides
U get 10x = 30
divide 10 on both sides
U get x is 3
B. 5(2x + 1) = 50
10x + 5 = 50
minus five on both sides
10x = 45
divide by 10 on both sides
The answer is x = 4.5

Peyton is collecting data on the lunch habits of students at Hyattsville Middle School. In one class, 14 students bring lunch from home, and 20 buy a school lunch. Hyattsville Middle School has 1700 students. From the data collected, how many students would Peyton predict would buy a school lunch? *
Answers
Answer:
Answer: Around 1000 students would buy a school lunch.
Step-by-step explanation:
We know that in one class, 14 students bring lunch from home, and 20 buy lunch in the school. This will be our sample.
In total we have 20 + 14 = 34 students, this will be our 100%.
The percentage of students that bring lunch from home can be estimated as the quotient between the number of students that bring lunch from home and the total number of students, times 100%.
p1 = (14/34)*100% = 41.18%
And the percentage of students that buy lunch at school can be computed in the same way:
p2= (20/34)*100% = 58.82%
Then, out of the 1700 students in middle school, we can estimate that around 58.82% of them will buy lunch in the school.
Then the exact number will be:
N = (58.82%/100%)*1700 = 1000
Around 1000 students would buy a school lunch.

Answers
Answer:
(0, -3), (2, 2), (4,7) these are just some points
Step-by-step explanation:
Put the equation in y=mx+b format. It will be 2y=5x-6.
y=5/2x -3
the first point will be (0, -3) because of the y-intercept which is negative 3. You can graph the slope from that point to get (2, 2) and (4, 7). You can get more points too
Answer:
There are infinite ordered pairs are on the line because it has infinite solutions.
Step-by-step explanation:
5x - 2y = 6
-5x -5x
-2y = -5x + 6
-2y/2 = -5x/-2 + 6/-2
y = 5/2x - 3
5x - 2(5/2x - 3) = 6
5x - 5x + 6 = 6
6 = 6

Step-by-step explanation:
Answer:
Slope: 3 over 1 or 3
Y-intercept: 2
Equation: y = 3x +2
Step-by-step explanation:
Slope: You count up (or rise) from one point to another and you get 3. Then count right (or run) until you get to a point and you get 1. Slope is rise over run so 3 over 1 or simplified, 3.
Y-intercept: The point where the line crosses the y-axis. That is 2.
Equation: m=slope
b= y-intercept
So, y = 3x + 2
