Suppose while at a store, you ask for change for five dollars. You get in return exactly twenty-four coins, all of which are nickels and quarters. How many nickels and quarters did you receive?
Answer: 5 nickels and 19 quarters
Step-by-step explanation:
Let represent the number of nickels and let represent the number of quarters.
From the problem we can write these two equations:
+ = 24; (0.05) + (0.25) = 5.00
Isolate in the first equation: = 24 − .
Substitute 24 − for and solve for :
(24 − )(0.05) + (0.25) = 5.00
24(0.05) − (0.05) + (0.25) = 5.00
1.20 − 0.05 + 0.25 = 5.00
1.20 + 0.20 = 5.00
0.20 = 3.80
= 19
Use = 19 to find :
+ = 24; + 19 = 24; = 5
Answer: 5 nickels, 19 quarters
Hope this helps!
Answer:
19 quarters and 5 nickles
Step-by-step explanation:
19 * .25 = 4.75 .05 * 5 = .25 4.75+.25= 5
You spin the spinner twice,
What is the probability of landing on an 8 and then landing on an 8?
Answer:
The probability of landing on 8 twice is 1/64
Step-by-step explanation:
If you spin the spinner once, there are 8 possibilities each time (1-8). The possibility of landing on the number 8 is 1 of these 8 possibilities. Its probability is therefore 1/8
Each spin is independent. In other words, the spins do not affect each other. The number you land on during the first spin does not impact the second spin's number. The probability of landing on 8 the second time is the same as the first time: 1/8
Because the two events are independent, we find the probability of them both occurring by multiplying them together.
1/8 times 1/8= 1/64

Jamie sees a sale at the Gaming Store where all games are the same price. He buys 3 video games. His sister talks him into also buying two $1.50 candy bars and a $2.00 drink for a total of $57.50. Write an equation to find the price of one video game.
Answer: 3x + 5 = 57.50
Step-by-step explanation:
Assume that the price of one video game is x. Jamie bought 3 video games so the expression will be:
= 3x
His sister talked him into buying two $1.50 candy bars and a $2.00 drink. The total of this is:
= 1.50 + 1.50 + 2.00
= $5.00
The total amount spent on both the video game and the snacks is $57.50. Equation will therefore be:
3x + 5 = 57.50
Two angles form a linear pair. The measure of one angle is eight
times greater than the measure of the other angle. Find the measure
of the bigger angle only.
Answer:
160
Step-by-step explanation:
Givens
Let the smaller angle = x
Let the larger angle = 8x
Equation
x + 8x = 180 Combine like terms
Solution
9x = 180 Divide by 9
9x/9 = 180/9
x = 20
Answer
The larger angle = 8 * 20 = 160
what two numbers multiply to 20 and add up to 9
Answer:
4 and 5
Step-by-step explanation:
The solution of the numbers 4 and 5 that gives multiplied by 20 and adds up to 9.
Used the concept of the equation that states,
An equation is a group of numerical variables and functions that have been combined using operations like addition, subtraction, multiplication, and division.
Given that,
The multiplication of two numbers is 20.
And, the addition of both numbers is 9.
Let us assume that the numbers are x and y.
Hence the equation for the given conditions,
[tex]x \times y = 20[/tex] ... (i)
[tex]x + y = 9[/tex] ... (ii)
From (ii);
[tex]x = 9 - y[/tex]
Substitute in (i);
[tex](9 - y) \times y = 20[/tex]
[tex]9y - y^2 = 20[/tex]
[tex]y^2 - 9y + 20 = 0[/tex]
[tex]y^2 - (5 + 4)y + 20 = 0[/tex]
[tex]y^2 - 5y - 4y + 20 = 0[/tex]
[tex]y (y - 5) - 4 (y - 5) = 0[/tex]
[tex](y - 5) (y - 4) = 0\\[/tex]
This gives,
[tex]y = 5\\y = 4[/tex]
From (i);
Substitute y = 5;
[tex]x = 9 - 5\\x = 4[/tex]
Substitute y = 4;
[tex]x = 9 - 4\\x = 5[/tex]
Therefore, the numbers are 5 and 4.

20/3=2(w+2/3)
What’s the value of w
Answer: w=8/3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
20 /3 =2(w+ ( 2 /3 )
20 /3 =(2)(w)+(2)( 2 /3 )(Distribute)
20 /3 =2w+ 4 /3
Step 2: Flip the equation.
2w+ 4 /3 = 20 /3
Subtract 4/3 from each side: 2w+ 4 /3 − 4 /3 = 20 /3 − 4 /3
Divide both sides by 2: 2w/ 2 =16 3 /2
Answer w=8/3
Answer:
w=8/3

Every new point on the graph is up 4, right 1
what is the slope of the line?
Answer: -2/3
i hope this helps!
Answer:
[tex]\sf -\cfrac{2}{3}[/tex]Step-by-step explanation:
To measure slope, we pick any two points on the line. Then we look at the horizontal and vertical distances between those points.
Going from the point on the left to the point on the right, the change in y is -2 and and the change in x is 3.
[tex]\sf Slope=\cfrac{rise}{run} =\cfrac{-2}{3}[/tex]
[tex]\sf = -\cfrac{2}{3}[/tex]
The slope of the line is -2/3
