Chris is making lemonade. The directions say to mix 5 cups of water with 2 scoops of powdered lemonade mix. How many cups of water should he use with 2.5 scoops of fruit mix? A.6 B.6.25 C.6.5 D. 6.75
Answers
25 * (18/5) = 90
B
Question 2:
2.5 * (5/2) = 6.25
B
In 1 minute = 18/5 boxes
In 25 minutes = 18/5 x 25 = 90
So correct option is B . 90
2 scoops = 5 cups of water
1 scoop = 5/2 cups of water
2.5 scoop = 5/2 x 2.5 = 6.25
So correct option is B. 6.25

We're simply just trying to factor this out.
So : What goes into ALL of these numbers?
6 does! :)
So, divide everything by 6.
6(3b²c - 2ab³ + 5ab)
Now, what else goes into these numbers/variables? :)
b does! So, simply factor out b.
6b(3bc - 2ab² + 5a)
----------------------------
To check if this is correct, simplify this & see if it is the same as our original equation.
(6b · 3bc) + (6b · -2ab²) + (6b · 5a)
Simplify.
(18b²c) + (-12ab³) + (30a)
Get rid of the parenthesis.
18b²c - 12ab³ + 30a = 10b²c - 12ab³ + 30ab (Our original equation)
Therefore, 6b(3bc - 2ab² + 5a) is our correct answer.

What is Linear Equation?
A linear equation is an algebraic equation of the form y = m x + b involving only a constant and a first-order linear term, where m is the slope and b is the y-intercept.
Given data ,
Let the two numbers be x and y , where the smaller number is x and larger number is y
Larger is 2 more than four times the smaller is expressed as
y = 2 + 4 x , be equation 1
The sum of two numbers is expressed as
x + y = 67 , be equation 2
Now we have two equations with two unknown variables
To find x and y , we substitute the value of y in equation 1
y = 67 - x
Therefore ,
67 - x = 2 + 4 x
5 x = 65
Dividing by 5 on both sides , we get
x = 13
Substituting the value of x in equation 2 , we get
y = 67 - 13
y = 54
Hence , the numbers are 13 and 54

What are the coordinates of the endpoints of the midsegment for △RST that is parallel TS¯¯¯¯¯ ?
Answers
Answer:
The end points of midsegement for triangle RST are (1,3) and(4,3) which is parallel to TS.
Step-by-step explanation:
We are given that a figure of triangle RTS in which the coordinates of R(0,6) , T(2,0) and S(8,0).
We have to find the end points of midsegment for triangle RST that is parallel TS
Let AB is midsegment where A is the mid point of segment RT and B is the midpoint of segment RS of triangle RST which is parallel to the segment TS.
To find the coordinates of end point of midsegment AB using midpoint formula
Midpoint formula :[tex]x=\frac{x_1+x_2}{2}, y=\frac{y_1+y_2}{2}[/tex]
The coordinate of A
[tex]x=\frac{0+2}{2}[/tex], [tex]y=\frac{0+6}{2}[/tex]
[tex]x_1=0,x_2=2,y_1=6,y_2=0[/tex]
[tex]x=1,y=3[/tex]
The coordinates of A is (1,3).
The coordinates of mid point B
[tex]x=\frac{0+8}{2},y=\frac{0+6}{2}[/tex]
[tex]x_1=0,y_1=6,x_2=8,y_2=0[/tex]
[tex]x=4,y=3[/tex]
The coordinates of midpoint B is (4,3).
Therefore, the end points of midsegement for triangle RST are (1,3) and(4,3) which is parallel.

A color printer prints 24 pages in 7 minutes. how many pages does it print per minute?
Answers
Final answer:
The color printer prints approximately 3.43 pages per minute. This is calculated by dividing the total number of pages (24) by the total printing time in minutes (7).
Explanation:
To calculate the number of pages a color printer prints per minute, we use the information provided that it prints 24 pages in 7 minutes. The calculation is a simple division problem:
Determine the rate by dividing the total number of pages by the total number of minutes.Pages per minute = Total pages printed ÷ Total minutesPages per minute = 24 pages ÷ 7 minutesCalculate the quotient to find the page rate.Pages per minute ≈ 3.43 pages per minuteTherefore, the printer prints approximately 3.43 pages per minute.
You are adding up the quarters and dimes from your piggy bank so you can buy a new book. you have a total of 50 coins that add up to $9.80. how many quarters and how many dimes do you have?
Answers
[tex]Q + D = 50[/tex]
Next, you know the value of a quarter is 0.25, and the value of a dime is 0.10, so you can set up the next equation:
[tex]0.25Q + 0.10D = 9.80[/tex]
Substituting the first equation into the second leads to the following:
[tex]0.25(50 - D) + 0.10D = 9.80[/tex]
Solving for [tex]D[/tex] will give you the number of dimes you have, and then you can easily figure out how many quarters you have as well.

Tony misplaced 777 stamps from his collection. He knows that each stamp of his is worth \$0.15$0.15dollar sign, 0, point, 15 and that the total value of them is now only \$5.55$5.55dollar sign, 5, point, 55.
Answers
Write an equation to represent the value of his stamp collection in terms of the number of stamps, s, that he had originally, and find the value of s.
Tony misplaced 7 stamps
Each stamp worth = $0.15
Total value of stamp now = $5.55
Let the number of stamps be 's'
Number of stamps now = s - 7 (misplaced 7 stamps)
price (number of stamps now ) = 0.55
0.15 (s - 7) = 5.55
Divide by 0.15 on both sides
s - 7 = 37
Add 7 on both sides
s = 44
Total number of stamps originally he had = 44 stamps
