Answer:
20x -6y
Step-by-step explanation:
Parentheses can be eliminated and like terms combined.
10x +y +10x -7y
= x(10 +10) +y(1 -7)
= 20x -6y
Scooter the clown buys flower hats for $27 each and plain hats for $22 each. If he spends a total of $250 on hats, how many hats have flowers?
Answer:
6 Flower hats
Step-by-step explanation:
If you are asking for whole number answers, then the answer is 6 Flower hats.
check:
6X27=162 and 4 plain hats, 4X22=88, 162+88=250.
hope it helps!
The required number of hats with flowers is 6.
Given that,
Scooter the clown buys flower hats for $27 each and plain hats for $22 each. If he spends a total of $250 on hats, how many hats have flowers is to be determined.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
Here,
let the hat with flower be x and the plain hats be y,
Total number of hats = 10
x + y = 10 - - - - - (1)
According to the question,
27x + 22y = 250 - - - - -(2)
Solving equation 1 and 2
gives
x = 6 and y = 4
Thus, the required number of hats with flowers is 6.

A model for a company’s revenue from selling a software package is R(p)=-2.5p^2+600p
Complete question is;
A model for a company's revenue from selling a software package is R = -2.5p² + 500p, where p is the price in dollars of the software. What price will maximize revenue? Find the maximum revenue.
Answer:
Price to maximize revenue = $100
Maximum revenue = $25000
Step-by-step explanation:
We are told that:
R = -2.5p² + 500p, where p is the price in dollars of the software.
The maximum revenue will occur at the vertex of the parabola.
Thus, the price at this vertex is;
p = -b/2a
Where a = - 2.5 and b = 500
Thus:
p = -500/(2 × -2.5)
p = -500/-5
p = 100 in dollars
Maximum revenue at this price is;
R(100) = -2.5(100)² + 500(100)
R(100) = -25000 + 50000
R(100) = $25000

What is cos theta when sin theta = sqrt 2/3
Answer:
Value of cosθ is ±√7/3 .
Step-by-step explanation:
According to the Question , value of :
[tex]\red{\implies sin\theta = \dfrac{\sqrt2}{3}} [/tex]
And , we know the identity of sine and cosine as ,
[tex]\boxed{\pink{\sf\implies sin^2\theta + cos^2\theta = 1} }[/tex]
Using , this identity we have ;
[tex]\implies sin^2\theta + cos^2\theta = 1 \\\\\implies \bigg( \dfrac{\sqrt2}{3}\bigg)^2 + cos^2\theta = 1 \\\\\implies \dfrac{2}{9} + cos^2\theta = 1 \\\\\implies cos^2\theta = 1 - \dfrac{2}{9} \\\\\implies cos^2\theta = \dfrac{9-2}{9} \\\\\implies cos\theta = \sqrt{\dfrac{7}{9}} \\\\\underline{\boxed{\blue{\bf \implies cos\theta = \pm \dfrac{\sqrt 7 }{3}}}}[/tex]
Now , here since θ is in 2nd quadrant and in 2nd quadrant cos is negative . Hence ,the value of cos will be :
[tex]\boxed{\orange{\bf \implies cos\theta =-\dfrac{\sqrt7}{3}}}[/tex]

Step-by-step explanation:
Rachel's cost = $35x + $15
Taylor's cost = $25x + $75
When are the costs equal? Rachel's cost = Taylor's cost?
35x + 15 = 25x + 75
35x - 25x = 75 - 15
10x = 60
x = 6
Check Rachel's 6 month cost is: 35 x 6 + 15 = 225
Check Taylor's 6 month cost is 25 x 6 + 75 = 225
Find the 89th term of the arithmetic sequence -16, -3, 10, ...
Answer:
uhm, i'm pretty sure it would be 1,128 because between each term is 13 units, and the first three terms are given. and 89-3 is 86. and 86*13=1,118. since the last term was 10, you need to add 10 to that, making your answer 1,128

Answer:
AB=AD
4x=x+15
3x=15
x=15/3
x=5
Answer:
x = 5
Step-by-step explanation:
In a kite, two disjoint pairs of sides are congruent, then
AB = AD , that is
4x = x + 15 ( subtract x from both sides )
3x = 15 ( divide both sides by 3 )
x = 5
X - 12 = -2
I need to solve X
Answer:
X = 10
Step-by-step explanation:
This is an easy algebra equation that you may not know but the only thing you can do is to add 12 on both sides. You should get 10 as a result.
Answer:
14
Step-by-step explanation:
14-12= -2
2 + 12=14
X=14 because if u subtract 14 and 12 u get -2 therefore the answer is 14

Answer:
a) 3/5=12/20
b) 5/6=25/30
Step-by-step explanation:
a.) To find the answer you would first find how much it took to get to 20. 5 times 4 is 20. Then to find the numerator you would do 3 times 4 and that would be 12.
b) To find the answer you would first find how much it took to get to 30. So 30/6 is 5. Then you would divide 25 by 5 and you would get 5.
find f(3) if f(x)=2x+4
Answer:
f(3) = 10
Step-by-step explanation:
If x = 3 then fill in the x's on the original equation and solve;
f(x) = 2x + 4
f(3) = 2(3) + 4
2 x 3 = 6
6 + 4 = 10
So, f(3) = 10

Brenda has $500 in her bank account. Every week, she withdraws $20 for expenses. Daryl has $650 in his bank account and withdraws $40 each week for expenses. How long will Daryl have less money than Brenda?
Group of answer choices
40x - 20x < 650 - 500
650 + 40x < 500 + 20x
650 - 40x < 500 - 20x
650 - 40x = 500 - 20x
Answer:
C. 650-40x<500-20x
Step-by-step explanation:
To withdraw means to take away (650-40x 500-20x)
Daryl, allegedly, has less money than Brenda (650-40x<500-20x)

Puan Kartini bought (5x - 4) kg of red chillies with the price of RM3x per kg. The total payment she paid is RM192. Calculate the mass, in kg, of the red chillies she bought.
Answer:
16 kg
Step-by-step explanation:
Mass = (5x - 4) kg
Unit Price = 3x/kg
Total Price = mass * unit price
Total Price = (5x - 4)kg * 3x/kg
Total Price = 15x^2 - 12x
Total Price = 192
15x^2 - 12x = 192
15x^2 - 12x - 192 = 0
5x^2 - 4x - 64 = 0
ax^2 + bx +c = 0
ac = 5(-64) = -320
ac = -20 * 16
-20 + 16 = -4
5x^2 - 20x + 16x - 64 = 0
5x(x - 4) + 16(x - 4) = 0
(x - 4)(5x + 16) = 0
x - 4 = 0 or 5x + 16 = 0
x = 4 or 5x = -16
x = 4 or x = -3.2
x cannot be negative because it would give a negative unit price, so we discard the negative answer.
x = 4
mass = 5x - 4 = 5(4) - 4 = 20 4 = 16
Answer: 16 kg

Last month, Grayson and Justine sold candy to raise money for their debate team. Justine sold 1 1/5 times as much candy as Grayson did. If Grayson sold 2/3 of a box of candy, how many boxes of candy did Justine sell?
Answer: 4/5 of a box of candy
Step-by-step explanation:
Justine sold 1¹/₅ times the ²/₃ of a box of candy that Grayson sold.
Justin sold;
= 1¹/₅ * ²/₃
= 6/5 * 2/3
= 12/15
= 4/5 of a box of candy

On Saturday, a local hamburger shop sold a combined total of 596 hamburgers and cheeseburgers. The number of cheeseburgers sold was three times the
number of hamburgers sold. How many hamburgers were sold on saturday?
Answer:
198 hamburgers
Step-by-step explanation:
Because the additive inverse of multiplication is division and since the cheeseburger are three times the number of hamburgers you should divide by three to get how many hamburgers were sold. Hope this helps
A VCR and TV were bought for 78.000 each. The shopkeeper made
loss of 4% on the VCR and a profit of 8% on the TV. Find the gain or loss
percent on the whole transaction.
Answer:
Profit % is 1.94% .
Step-by-step explanation:
The CP of both VCR and TV were same that is Rs 78,000 . So ,
[tex] => CP \ of \ the \ buyer \ = \ Rs78,000 \times 2 = Rs 156,000 [/tex]
As per Question , on one he made a loss of 4% and profit of 8% on the other .
And , the net SP would be ,
[tex] => Total \ SP \ = \ \dfrac{96}{100}\times Rs 78,000 + \dfrac{108}{100}\times Rs 78,000 \\\\=> Total\ SP = Rs 74,800 + Rs 84240 \\\\\boxed{\red{\bf => Total \ SP= Rs 159,040 }}[/tex]
So , here clearly SP > CP . So , there's a profit .Hence profit % would be :-
[tex] => Profit \% = \dfrac{ SP - CP }{CP}\times 100 \\\\=> Profit \% = \dfrac{Rs 159,040-Rs156,000}{Rs156,000}\times 100 \\\\=> Profit\% = \dfrac{3040}{156000}\times 100 \\\\\underline{\blue{\bf => Profit\% = 1.94 \% }}[/tex]
