My friend Dubble got 10 rews and corazs for about $32. Rews for $2 each and some corazs for $8 each
Answer:
"Dubble" bought 10 rews for $2.00 each and 1 corazs for $8.00 each
-I put quotation marks on Dubble bc i didnt know if it was a boy or girl name sorryyy its.. um.. unique :) -
Step-by-step explanation:
The price for the rews is 10x 2 because the price of each is $2 and he got 10 so he spent $20 on rews.
Then you subtract the total amount of money "Dubble" used buying these things and the amount of money "Dubble" used on the rews which is 32-20=8
The last step is that you divide 8 by the pice of each corazs which is 8 divided by 8 so the answer is 1.
Hope this helped you sorry im a little late bubs.<3

I got this question on a math homework and I don't understand it, 5 5/8 cups of water fill 4 1/2 identical water bottles. How many cups fill each bottle?
Answer:
1-1/4 cups (1 and 1/4 cups) or 1.25 cups
Step-by-step explanation:
To find the answer you need to take the total volume (5-5/8 cups) and divide it by the number of bottles you have:
5-5/8 divided by 4-1/2
There are two easy ways to do this: you can convert the mixed fractions into decimal form (A) or into improper fractions (B).
A)
First, convert to decimal form:
5-5/8 = 5.625 and 4-1/2 = 4.5
Then, you divide them:
5.625 / 4.5 = 1.25 (converted back to fraction form, if thats what you need, is 1-1/4)
B)
First, convert to mixed numbers:
5-5/8 = 45/8 and 4-1/2 =9/2
Then, you divide them:
45/8 / 9/2
When you divide fractions, you multiply by the inverse of the number you're dividing by (that means swapping the numerator and denominator):
45/8 * 2/9 = 90/72 (converted back to a mixed fraction, this equals 1-1/4)

1. Geneva has 24 points. Then her spin lands on blue. What is her score now? Explain.
Blue = + 4. This means that you will need to add 4 to 24, causing Geneva's new amount of points to be 28. You could put down,
Geneva now has 28 points. Blue is equal to +4, so I added 24 + 4 to get 28.
2. Geneva and Juan start a new game. Each player has 0 points.
a. Geneva's first two spins are yellow and red. What is her score now? Explain.
Geneva's score is now -2. Yellow is equal to -4, red is equal to +2. -4 + 2 = -2.
b. Juan's first two spins are red and green. What is his score now? Explain.
Red is equal to +2 and green is equal to -1. That means that Juan has 1 point because 2 + -1 = 1.
c. Which player has a greater score now? Explain.
Juan has a greater score. He has a greater score because 1 is greater than -2.
Given FGH with vertices F(-1, 3), G(-5, 1), and H(-3, 5) reflected by Rx-axis
Find the coordinate of vertices F'G'H the image of FGH
1, F(-1, 3), G(-5, 1), and H(-3, 5)
2, F(-1, -3), G(-5, -1), and H(-3, -5)
3, F(1, 3), G(5, 1), and H(3, 5)
4, F(-1, 3), G(-5, 1), and H(-3, -5)
Answer:
Option F is true.
Step-by-step explanation:
The rule of reflection across the x-axis
P(x, y) → P'(x, -y)
For example, when a point P with coordinates (1, 2) is reflected across the x-axis, the coordinates of the image of point P will be: P'(1,-2).
i.e.
P(x, y) → P'(x, -y)
P(1, 2) → P'(1, -2)
Now, given FGH with vertices F(-1, 3), G(-5, 1), and H(-3, 5) reflected by Rx-axis.
Using the rule of reflection across the x-axis
P(x, y) → P'(x, -y)Thus, the coordinate of vertices F'G'H the image of FGH will be:
F(-1, 3) → F'(-1, -3)
G(-5, 1) → G'(-5, -1)
H(-3, 5) → H'(-3, -5)
Hence, option F is true.

Madelyn has a total of 15 dimes and quartets in her piggy bank. The total amount of money in her piggie bank is $2.85. Write and solve a system of equations to determine the number of dimes and the number of quarters in madelyn’s piggie bank.
The system of equations is x + y = 15 and 0.10x + 0.25y = 2.85. Then the number of dimes and quarters will be 6 and 9, respectively.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
Madelyn has a total of 15 dimes and quartets in her piggy bank. The total amount of money in her piggy bank is $2.85.
Let 'x' be the number of dimes and 'y' be the number of quarters. Then the equations are given as,
0.10x + 0.25y = 2.85 ....1
x + y = 15 ....2
From equations 1 and 2, then we have
0.10(15 - y) + 0.25y = 2.85
1.5 - 0.10y + 0.25y = 2.85
0.15y = 1.35
y = 9
Then the value of the variable 'x' is given as,
x + 9 = 15
x = 6
The system of equations is x + y = 15 and 0.10x + 0.25y = 2.85. Then the number of dimes and quarters will be 6 and 9, respectively.

How many solutions does the following equation have?
3x + 7 + 2x = 5x + 7
One. Many. None
Answer:
Infinite/many
Step-by-step explanation:
3x + 7 + 2x = 5x + 7
3x + 2x + 7 = 5x + 7
5x + 7 = 5x + 7
5x - 5x + 7 = 7
7 = 7
Infinite solutions
Answer: many (all real numbers)
Step-by-step explanation:
1) add 2x and 3x to give you 5x
You now have 5x+7=5x+7
2) you can simplify this by subtracting 7 on both sides and dividing by 5
3) you are then left with x=x

Notes:
In line 2, I replaced r with 2t because the radius r is increasing at a rate of 2 cm per second. So if t is the number of seconds, then 2t is the radius in cm at time t.In line 4, I multiplied both sides by 3 to clear out the fractions. On the next line, I divided both sides by 4pi.Find the product. Write your answer as a fraction in simplest form.

Find the least whole number that can replace blank 80 to make the statement true. ÷ 18 > 86
Answer:
649
Step-by-step explanation:
Given the expression :
__ ÷ 18 > 86
Let blank = y
y ÷ 18 > 36
y / 18 > 36
Multiply both sides by 18
(y / 18) * 18 > 36 * 18
y > 648
Hence, the least whole number which can make the statement true is (648 + 1) = 649

1.3181818...... as fraction units lowest term
Answer:
29/22
Step-by-step explanation:
Let x = 1.31818181818....
Then, 10x = 13.18181818..., and 1000x = 1318.18181818..... Subtracting the first equation from the second, we get that 990x = 1305. This means that x = 1305/990. In lowest terms, this is 29/22.

Write an equation in slope-intercepts form for the line that passes through (5, -4) and is perpendicular to the line described by 2x-10y=0
EXPLAIN what you did in each step to arrive at your answer plz
Answer:
y = -5x + 21
Step-by-step explanation:
First, put 2x - 10y = 0 into slope intercept form to find the slope:
Subtract 2x from both sides:
-10y = -2x
Divide each side by -10:
-10y = -2x
y = 1/5x
So, the slope of the line is 1/5.
Perpendicular lines have opposite reciprocal slopes, so the slope of the other line will be -5.
Then, use the equation y = mx + b to plug in the slope and the point given.
Solve for b:
y = mx + b
-4 = -5(5) + b
-4 = -25 + b
21 = b
Lastly, plug in the slope and b into y = mx + b to create the equation in slope intercept form:
y = -5x + 21 is the equation
