Brielle's piggy bank has all nickels and dimes. The total value of the money in her piggy bank is
$7.80. If Brielle has 66 nickels, write and solve a linear equation to find the number of dimes she
has.
What’s the linear equation
Answer:
Step-by-step explanation:
7.80=66(.05)+.10(x)
7.80=3.30+.10(x)
7.80=3.30+.10x
4.50=.10x
x=45
Check
66 nickels at .05=3.30
45 dimes at .10= 4.50
3.30+4.50= 7.80

Consider this system:
3x + 1/2y = 3
6x - y = 2
Which of the following operations would eliminate the y-terms if the two equations were added together afterward?
A. Multiply the first equation by -2.
B. Multiply the first equation by 2.
C. Multiply the second equation by -2.
D. Multiply the second equation by 2.
Answer:
B. Multiply the first equation by 2
hope this helps tell me if you need more :)
Multiply the first equation by 2 then the variable y will be eliminated. Then the correct option is B.
What is the linear system?A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
Consider this system:
3x + 1/2y = 3 ...1
6x - y = 2 ...2
The operations would eliminate the y-terms if the two equations were added together afterward will be
Multiply the first equation by 2. Then we have
6x + y = 6
6x - y = 2
Add the above equations, then we have
12x = 8
y is eliminated.

Grace and Zoe like to jump rope grades jump 66 times a minute Zoe jumps 56 times a minute they both Count Their jumps today and together they jump 1266 times in the total of 21 minutes how long did each girl jump
Answer:
Grace jumps for 9 minutes.
Zoe jumps for 12 minutes.
Step-by-step explanation:
Let the time for which Grace jumps the rope = [tex]x[/tex] minutes
Let the time for which Zoe jumps the rope = [tex]y[/tex] minutes
As per question statement:
[tex]x+y=21 ..... (1)[/tex]
Number of times Grace jumps in one minute = 66
Number of times Zoe jumps in one minute = 56
Number of times Grace jumps in [tex]x[/tex] minutes = 66
Number of times Zoe jumps in [tex]y[/tex] minutes = 56
As per question statement:
[tex]66x+56y=1266 ...... (2)[/tex]
Multiplying equation (1) with 66 and subtracting equation (2) from it:
[tex]10y = 1386 - 1266\\\Rightarrow 10y=120\\\Rightarrow y =\bold{12\ min}[/tex]
By equation (1):
[tex]x=21-12=\bold{9\ min}[/tex]
Therefore, the answer is:
Grace jumps for 9 minutes.
Zoe jumps for 12 minutes.

(a) (4,4) is a point on a locus whose equation is y2 = kx. Show that (16,8) is another point on the locus.
(b) (2,3) is a point on a locus whose equation is 5x +by= 16. Show that (0,8) is another point of the locus
Step-by-step explanation:
plug the coordinate points into the equations and solve for the remaining variable.
b) (2,3) - 5(2) + b(3) = 16
10 + 3b = 16. 3b= 6. b = 2
(0,8) - 5(0) + 2(8) = 16. 0+ 16 = 16. ☆
a) (4,4) assume based on results you meant y squared. (y^2)
(4)^2 = 4k. 16 = 4k. k = 4
(8)^2 = 4(16). 64 = 64. ☆
Answer:
Please check the explanation.
Step-by-step explanation:
a)
Given
(4,4) is a point on a locus whose equation is y²=kx
Putting (4, 4) in y²=kx
(4)² = k(4)
16 = 4k
k = 16/4
k = 4
Checking the point (16, 8) on the locus
y²=kx
Putting (16, 8) and k =4 in y²=kx
y²=kx
(4)² = 4×4
16 = 16
L.H.S = R.H.S
Therefore, (16, 8) is another point on the locus.
b)
Given
(2, 3) is a point on a locus whose equation is 5x +by= 16
Putting (2, 3) in 5x +by= 16
5x+by=16
5(2)+b(3)=16
10+3b=16
3b=6
b=6/3
b=2
Putting (0, 8) and b=2 in 5x +by= 16
5x +by= 16
5(0)+2(8)=16
0+16=16
16=16
L.H.S = R.H.S
Therefore, (0, 8) is another point on the locus.

14. Devon has an area rug with a width 3 feet less than its length, l. He has purchased a larger rug to fit into his new dorm room. Both length and width of Devon's new rug are 2 feet longer than the original. Find the simplified expression of the perimeter and the NEW rug. plsssss help.me show work
Answer:
Perimeter of the new rug = 4x+2 feet
Step-by-step explanation:
Let the length be x feet and the width of the first rug will be x- 3 feet
Area = length * breadth = x * (x-3) = x²- 3x
Length of the new rug = x+2 feet
Width of the rug = x+2-3= x-1 feet
Perimeter of the recatngle = 2( length + breadth)
= 2( x+2 + x-1)
= 2 (2x+1)
= 4x+2 feet
how do you solve
x-3y=-5
x+3y=1
Answer:
I got you fam
Step-by-step explanation:
First One:
x -3y = -5
x = -5 + 3y
Or
x -3y = -5
-3y = -5 -x
y = 5/3 + x/3
Second one:
x +3y = 1
x = 1 - 3y
Or
x + 3y = 1
3y = 1 -x
y = 1/3 - x/3

Lindsey’s goal is to sell at least 35 candles at each of 15 craft fairs.
She makes 24 candles each day for 20 days.
Explain whether Lindsey makes enough candles to reach her goal.
Group of answer choices
A.Lindsay makes 48 candles. She divides 48 by 24 to get 2. She does make enough candles.
B.Lindsay makes 440 candles. She divides 440 by 15 to get 29 R4. She does make enough candles.
C.Lindsay makes 44 candles. She divides 44 by 20 to get 2R 4. She does not make enough candles.
D.Lindsay makes 480 candles. She divides 480 by 15 to get 32. She does not make enough candles.
Answer: D.Lindsay makes 480 candles. She divides 480 by 15 to get 32. She does not make enough candles.
Step-by-step explanation: 24 times 20 is 480. That is how many she made all together.
Lindsay makes 480 candles. She divides 480 by 15 to get 32. She does not make enough candles and this can be determined by using the arithmetic operations.
Given :
Lindsey’s goal is to sell at least 35 candles at each of the 15 craft fairs. She makes 24 candles each day for 20 days.The following steps can be used in order to determine whether Lindsey makes enough candles to reach her goal:
Step 1 - The arithmetic operations can be used in order to determine whether Lindsey makes enough candles to reach her goal.
Step 2 - According to the given data, Lindsey makes 24 candles each day for 20 days. So, the total number of candles she makes at the end of 20 days is:
[tex]=24\times 20[/tex]
= 480 candles
Step 3 - Also it is given that Lindsey’s goal is to sell at least 35 candles at each of 15 craft fairs. So, the total candles required is:
[tex]=35\times 15[/tex]
= 525 candles
Therefore, the correct option is D).
