Answer:
x + y = 64
x = 10 + y
Yo-yo = 27
Xylophone = 37
Step-by-step explanation:
Let :
Xylophone club = x
Yo - Yo club = y
Total members = 64
Xylophone club has 10 more members than yoyo
Hence,
x + y = 64 - - (1)
x = 10 + y - - (2)
Put x = 10 + y in (1)
10 + y + y = 64
10 + 2y = 64
2y = 64 - 10
2y = 54
y = 54 / 2
y = 27
From (1)
x + 27 = 64
x = 64 - 27
x = 37

W + b =13
6.5w + 2b = 57.5
Answer: w = 7, x = 6
Step-by-step explanation: Solve by substitution
W + b = 13
rewrite as b = 13 - w and substitute that value for b in the second equation
6.5w + 2b = 57.5 Then solve for w
6.5w + 2(13-w) = 57.5 . Distribute
6.5w + 26 - 2w = 57.5 . Subtract 26 from both sides. Combine like terms and simplify
6.5w - 2w = 57.5 - 26
4.5w = 31.5 Divide both sides by 4.65
w = 7 . Substitute 7 for w in the first equation and solve for b
7 + b = 13 . Subtract 7 from both sides
b = 6
if John has test scores of 90 and 76 with one test remaining to be taken, what score must he make on the last test to end up with an 86 average?
Answer: The last score must be 92%
Step-by-step explanation: To find the average, you add all the terms, then divide by the number of terms.
86 = [tex]\frac{90 + 76 + x}{3}[/tex]258 = 90 + 76 + x (multiple both sides by 3)258 = 166 + x (combine like terms)92 = x (subtract 166 from both sides)Solve for brainlist ❤️❤️

The model includes a new park in the center of the city. If the dimensions of the
park in the model are 9 inches by 17 inches, what are the actual dimensions of the
park
The question is incomplete. Here is the complete question.
As a part of city building refurbishment project, architects have constructed a scale model of several city builidings to present to the city commission for approval. The scale of the model is 1 inch = 9 feet.
The model includes a new park in the center of the city. If the dimensions of the park in the model are 9 inches by 17 inches, what are the actual dimensions of the park?
Answer: 81 feet by 153 feet
Step-by-step explanation: Unit Scale is a ratio comparing actual dimensions of an object to the dimensions of model representing the actual object.
In the refurbishment project, the unit scale is given by
1 inch = 9 feet
So, the dimensions of the new park in actual dimensions would be
1 inch = 9 feet
9 inches = x
x = 9.9
x = 81 feet
1 inch = 9 feet
17 inches = y
y = 17.9
y = 153 feet
The actual dimensions of the new park are 81 feet by 153 feet.

‘Saturn' chocolate bars are packed either in boxes of 5 or boxes of 12. What is the smallest number of full boxes required to pack exactly 2005 ‘Saturn' bars?
Answer:
167
Step-by-step explanation:
Given that :
Saturn chocolate bars are either packed in 5's or 12's
The smallest number of boxes required to pack 2005 bars ;
In other to arrive at smallest number of boxes, then we need to pack primarily in 12's
Number of boxes required for 12 packing :
2005 /12 = 167.08333 boxes (167, remainder 1)
Hence, smallest number of boxes to pack 2005 saturn chocolate bars is 167

What is the sign of the product (3)(-3)(-2)(4)? (5 points) Select one: a. Positive, because the products (3)(-3) and (-2)(4) are negative, and the product of two negative numbers is positive b. Positive, because the products (3)(-3) and (-2)(4) are positive, and the product of two positive numbers is positive c. Negative, because the products (3)(-3) and (-2)(4) are negative, and the product of two negative numbers is negative d. Negative, because the products (3)(-3) and (-2)(4) are positive, and the product of two positive numbers is negative
Answer: a. Positive, because the products (3)(-3) and (-2)(4) are negative, and the product of two negative numbers is positive
Step-by-step explanation: It is also possible to rearrange the factors.
(3)(4) = 12 a positive number.
(-3)(-2) = 6, a positive number. Again "a negative times a negative is a positive" --Jaime Escalante, Stand and Deliver
Now you have two positive numbers: 12×6 = 72
The product is positive either way.

Answer:
Step-by-step explanation:
the ratio between similar triangles are constant.
so 11/14 has to be equal to z/8 and also a15 = 11/14
so from this we can conclude that z = 8*14/11 = 10.18
Answer:
z = 11 and a = 12
Step-by-step explanation:
These two triangles are similar, in this case, the same angles but different sizes. The answer to this problem is the length of the sides of the triangles. You are given the right side's length on both triangles. The first triangle's sides are 3 (inches, cm, whatever form of measurement is being used) bigger than the second triangle's. Using this information, you can figure out the quantity of both a and z.

An investor bought a number of shares of stock for $1600 after Priess dropped by $10 per share she sold all but four of her shares for $1120 how many shares that she originally by?
Answer:
She originally bought either 20 or 32 shares
Step-by-step explanation:
An investor bought a number of shares of stock for $1600 after Price dropped by $10 per share she sold all but four of her shares for $1120 how many shares that she originally by?
Let the number of shares she bought be represented by 1600/x
This is calculated as:
1600/x = 1120/x + 10 + 4
Multiply through by (x)(x - 10)
1600(x-10) = 1120(x) + 4(x)(x - 10)
1600x - 16000 = 1120x + 4x² - 40x
Collect like terms
4x² + 1120x - 1600x - 40x +16000 = 0
4x² - 520x + 16000 = 0
Using the Almighty formula method
= -b ± √b²- 4ac/2a
a = 4, b = -520 , c = 16,000
Hence:
= -(-520) ± √-520² - 4 × 4 × 16000/2 × 4
= 520 ± √14400/8
= 520 ± 120/8
520 - 120/8
= 400/8
= 50
520 ± 120/8
= 520 + 120/8
= 640/8
= 80
Since we have:
1600/x
When x = 50
= 1600/50
= 32
When x = 80
= 1600/80
= 20
Therefore, she originally bought either 20 or 32 shares

Thanks for the help!
Answer:
[tex]\mathrm{1.\:D.\:8.4\%}\\\mathrm{2.\:C.\: \$96.60}\\\mathrm{3.\:D.\: \$227.85}\\\mathrm{4.\:B.\:\$490}[/tex]
Step-by-step explanation:
1. The car's initial price was $273. Since the sale price is $250, the car is on a [tex]273-250=\$23[/tex] discount. The percent of discount is the discount price over the initial price:
[tex]\frac{23}{273}\approx \fbox{$8.4\%$}[/tex].
2. Since the weight racks were initially priced $46, then marked up 210%, their mark-up is:
[tex]46\cdot2.1=\fbox{$\$96.60$}[/tex]
*Worth noting that this is the mark-up (as the question is asking), not the total price after the mark-up.
3. The TV's initial price is $325.50. If it's on sale for 30%, it's final price will be [tex]100\%-30\%=70\%[/tex] of the initial price:
[tex]\$325.50\cdot 0.7=\fbox{$\$227.85$}[/tex]
4. The final retail price will be the initial price + the mark-up:
[tex]280+280(0.75)=\fbox{$\$490$}[/tex].

Thelma and Louise ordered take-out from Belle Taco. Thelma ordered 2 tacos and 1 quesadilla and paid $5.51. Louise ordered 2 quesadillas and 1 taco and paid $7.09.
Answer:
The cost of 1 taco is $1.31 and 1 quesadilla is $2.89
Step-by-step explanation:
Let [tex]x[/tex] be the cost of 1 tacos and [tex]y[/tex] be the cost of 1 quesadilla
Thelma's order
[tex]2x+1y=5.51\quad\ldots(i)[/tex]
Louise's order
[tex]1x+2y=7.09\quad\ldots(ii)[/tex]
Performing the operation [tex]2\times (i)-(ii)[/tex] we get
[tex]4x+2y=11.2[/tex]
[tex]x+2y=7.09[/tex]
[tex]3x=3.93\\\Rightarrow x=\dfrac{3.93}{3}\\\Rightarrow x=1.31[/tex]
[tex]2x+y=5.51\\\Rightarrow 2\times 1.31+y=5.51\\\Rightarrow y=5.51-(2\times 1.31)\\\Rightarrow y=2.89[/tex]
The required answer is
The cost of 1 taco is $1.31 and 1 quesadilla is $2.89.
