Madison is a high school basketball player. How many points would Madison score in a game if she made 8 free throws (worth one point each) and 6 three point shots? How many points would Madison score in a game if she made xx free throws and yy three point shots?
Answer: 26; 1x + 3y
Step-by-step explanation:
a. The number of points that Madison would score in a game if she made 8 free throws (worth one point each) and 6 three point shots would be:
= 8(1) + 6(3)
= 8 + 18
= 26 points
The number of points that Madison would score in a game if she made x free throws and y three point shots would be:
= 1(x) + 3(y)
= x + 3y
Answer:
26 and 1x+3y
Step-by-step explanation:
26 and 1x+3y

There are 49 female performers in a dance recital. The ratio of men to women is 2:7. How many men are in the dance recital? There are men in the dance recital.
Answer:
Number of men= 13.99 = 14
Step-by-step explanation:
Giving the following information:
There are 49 female performers in a dance recital. The ratio of men to women is 2:7.
First, we determine the proportion of men to women:
Proportion men to women= 2/7= 0.2857
Now, we calculate the number of men in the show:
Number of men= 0.2857*49
Number of men= 13.99 = 14
Sasha has a 35% off coupon. Her total before tax came to $23.00. How much did the item originally cost? (round to the nearest hundreds) PLS help!! (middle school and pls show work)
Answer:
The original cost of the product was $35.68.
Step-by-step explanation:
As Sasha has a discount coupon of 35%, the final amount that he will pay is 65% of the initial value of the product (100 - 35). Thus, 65% of the value is $ 23. Therefore, to determine the initial cost of the product, it is necessary to perform the following calculation:
65 = 23
100 = X
((100 x 23) / 65) = X
2,300 / 65 = X
35.68 = X
Therefore, the initial value of the product was $ 35.68.

He bought 10 pounds of Golden apples and 20 pounds of Fuji apples
which costs him $20 and $60.
What is a linear equation?A linear equation is an algebraic equation of degree one. In general, the variable or the variables(in the case of a linear equation in two variables) the variables are x and y.
Let Fuji apples be F and Golden apples be G.
In total, he bought 30 pounds of apples.
∴ F + G = 30...(i)
And,
He bought 3 pounds of Fuji apples and 2 pounds of Golden apples.
3F + 2G = 80...(ii)
Now, multiplying eqn(i) by 3 and subtracting from (ii) we get G = 10 and hence F = 20.
So, he bought 10 pounds of Golden apples and 20 pounds of Fuji apples
which costs him $20 and $60.

Express z 1 = 17 [ cos ( π ) + i sin ( π ) ] z 1 =17[cos(π)+isin(π)]z, start subscript, 1, end subscript, equals, 17, open bracket, cosine, left parenthesis, pi, right parenthesis, plus, i, sine, left parenthesis, pi, right parenthesis, close bracket in rectangular form. Express your answer in exact terms.
Answer:
z1 = -17 + 0i
Step-by-step explanation:
Given the complex number z1 =17[cos(π)+isin(π)], we are to express it in rectangular form as shown;
Since cos(π) = -1 and sin(π) = 0, the equation becomes;
z1 =17[cos(π)+isin(π)]
z1 =17[(-1)+i(0)]
z1 = 17(-1 + 0i)
z1 = -17 + 0i
Hence the complex number in rectangular form is expressed as z1 = -17 + 0i

7th grade math help me pleaseee :)
Answer:
answer of 2a)
He started with $24 and spent $16. Let a represent his account balance after he bought the notebook and pens. Then
24–16=a
His new account balance is $8.
He has $8 in his account and then he deposited b dollars. His account balance is now $28. Then
8+b=28
His deposited $20 in his account.
He has $28 and spent $34. Let c represent his account balance after he bought the book. Then
28–34=c
His new account balance is -$6.
He started with an account balance of -$6 and paid the debt off so his account balance is 0. If d is the amount money he deposited to pay off his debt, then
−6+d=0
He deposited $6.
answer of 2b)
If he spends more than he has in his account, then we are subtracting a bigger number from a smaller number, and the result is negative. ... The opposite of a positive number is a negative number, so it makes sense to represent his account balance with a negative number when he owes money to the bookstore.

Answer:
7. Option B:40 is the correct answer.
8. Option D: y = 40x+75 is the correct answer.
Step-by-step explanation:
Given that:
Charges per hour = $40
Fee charged by repairman = $75
x = number of hours
y = total fee
According to given statement;
y = 40x+75
The standard equation is
y = mx + b
On comparing;
Slope of the line is given by m, therefore
Slope = m = 40
Hence,
7. Option B:40 is the correct answer.
8. Option D: y = 40x+75 is the correct answer.

Answer:
x = 2
y = -1
Step-by-step explanation:
8x + 2y = 14
2x + y = 3
In order to find the number x represents, you have to make the number of y for both equations the same. So:
8x + 2y = 14
(×2) 4x + 2y = 6 (×2)
Then, you can cancel the y off both equations, which will leave:
8x = 14
4x = 6
To find 4x, you have to find the difference between both equations, so you have to:
14 - 6 = 8
Now that the actual number 4x represents is 8, so:
4x = 8
(÷4) x = 2 (÷4)
Now to find y, substitute the letter x with 2:
2x + y = 3
2 (2) + y = 3
4 + y = 3
4 - 3 = -y
1 = -y
(× -) -1 = y (× -)
Answer: x = 2
y = -1

Evaluate: 4+8÷2x (6-3)
Answer:
hello there
ok so the answer is 4 + [tex]\frac{4}{3x}[/tex]
Step-by-step explanation:
hope this helps!
Answer:
12x+4
Step-by-step explanation:
We can solve this by using PEMDAS (parentheses exponents multiplication division addition subtraction) to solve this in the correct order:
4+8÷2x (6-3)
So first we solve (6-3) since it’s in parentheses:
4+8÷2x (3)
Now we multiply 3 times 8/2x:
4+8/2x(3)
4+12x
(Put in order)
12x+4
And that^ is the answer because we cannot simplify any further!
Hope this helps :)

Answer:
Presumably you're solving for x here? Without further information we'll assume that.
With that in mind, x is approximately equal to 0.86 and -0.46
Step-by-step explanation:
Let's start by putting it in the usual ax² + bx + c format.
[tex]5x^2- 2x = 2\\5x^2 - 2x - 2 = 0\\[/tex]
let's solve it. First we'll multiply both sides by five, making the first term a perfect square:
[tex]25x^2 - 10x - 10 = 0\\[/tex]
Now we'll add 11 to both sides:
[tex]25x^2 - 10x + 1 = 11\\[/tex]
Which makes the left side a perfect square:
[tex](5x - 1)^2 = 11[/tex]
And now we can solve for x:
[tex](5x - 1)^2 = 11\\\\5x - 1 = \sqrt{11} \\\\5x = 1 + \sqrt{11}\\\\x = \frac{1 + \sqrt{11}}{5}[/tex]
Note that there's no apparent way of drawing the ± symbol when editing equations, so take that + sign as actually being ±.
That gives us two answers:
[tex]x = \frac{1 + \sqrt{11}}{5}\\\\x \approx \frac{1 + 3.32}5\\\\x \approx \frac{4.32}5\\\\x \approx 0.86[/tex] [tex]x = \frac{1 - \sqrt{11}}{5}\\\\x \approx \frac{1 - 3.32}5\\\\x \approx \frac{-2.32}5\\\\x \approx -0.46[/tex]
