Answer:
x=5, y=2
Step-by-step explanation:
Use the information given:
2x+y=12x+3y=11Subtract them because we have two variables and two equations:
2x+y=12
- x+3y=11
–––––––––
x-2y=1
We can by 1+2y (Add 2y to both sides) instead of x:
2(1+2y)+y=122+4y+y=122+5y=125y=10y=2(1+2y)+3y=111+2y+3y=111+5y=115y=10y=2Now we can figure out x as we know y:
2x+1(2)=122x+2=122x=10x=5x+3(2)=11x+6=11x=5Complete the last step by simplifying the expression square root of 180What is simplified?
Answer:
about 13.
Step-by-step explanation:
sqrt of 180=13.416...
Answer:
6√5
Step-by-step explanation:
180=[tex]2^{2} *3^{2} *5[/tex]. So we can say that 180=6•6•5. So, √180=6√5.

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

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

Draw the dilation of ABCD using center D and scale factor 1/3. Label the dilation EFGH
Answer:
Please find attached, the required drawing of quadrilateral ABCD and the dilation of quadrilateral ABCD scaled down by a scale factor of 1/3
Step-by-step explanation:
The coordinates of the quadrilateral ABCD are;
A(0, 6), B(6, 6), C(9, 0), D(0, 0)
From the dilation by a scale factor of 1/3, using D as the center of dilation, we have from the attached drawing, the following coordinates of the quadrilateral EFGH as E(0, 2), F(2, 2), G(3, 0) H(0, 0) which is the quadrilateral ABCD scaled down by 1/3
Which option? Help would be appreciated greatly
Answer:
Option 4: 6^7
Step-by-step explanation:
The rule is that when multiplying same bases with different exponents, the exponents only get added.
In other words, (x^a)(x^b)=x^(a+b)
In this case, (6^3)(6^4)=6^(3+4)=6^7
Therefore, Option 4 is correct

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).

Answer:
6 servings
Step-by-step explanation:
Let's say there are x 2/3 cup servings in a 4 cup container.
We multiply 2/3 by x to get the amount of cups that will produce and set that equal to 4 (because we want 4 cups):
(2/3) * x = 4
Divide both sides by 2/3, or multiply both sides by the reciprocal 3/2:
x = 4 * (3/2) = 12/2 = 6
The answer is 6 servings.

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.
