Jacob went bowling over the weekend. On Saturday, he bowled at Bowlero, where he
rented shoes for $3.25 and paid $3.75 for each game. On Sunday, he bowled at the
Cowtown Bowling Center, where he rented shoes for $2.50 and paid $4.00 per game. If
he spent the same amount each day, how many games did he bowl? (Let the number of
games played = x.)
Answer:
x= 3
Step-by-step explanation:
Blowlero's cost of shoes + the cost of one game = $7.00. If we add the cost of a game two more times, we get $14.50
At Cowtown Bowling Center, we can do the same thing. The cost of shoes + the cost of a game= $6.50. If we add the cost of a game two more times, we get $14.50.
For Jacob to have spent the same amount each day, he would have had to played three games at both places.

x = 3

if xr-st=r, which expression represents x
Answer:
To get an expression relating to x you need to have x alone on one side of your equation. ie x =
Try this:
rx - st = r
remove st from the rx side
rx = r + st
now divide by r
x = (r + st)/r

Pulling out like terms
3.1 Pull out like factors :
8x2 - 8 = 8 • (x2 - 1)
Trying to factor as a Difference of Squares:
3.2 Factoring: x2 - 1
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 1 is the square of 1
Check : x2 is the square of x1

4.1 A product of several terms equals zero.
When a product of two or more terms equals zero, then at least one of the terms must be zero.
We shall now solve each term = 0 separately
In other words, we are going to solve as many equations as there are terms in the product
Any solution of term = 0 solves product = 0 as well.
Equations which are never true:
4.2 Solve : 8 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
4.3 Solve : x+1 = 0
Subtract 1 from both sides of the equation :
x = -1
Solving a Single Variable Equation:
4.4 Solve : x-1 = 0
Add 1 to both sides of the equation :
x = 1
Two solutions were found :
x = 1
x = -1
The results of a national survey showed that on average, adults sleep 7.3 hours per night. Suppose that the standard deviation is 1.2 hours and that the number of hours of sleep follows a bell-shaped distribution. If needed, round your answers to two decimal digits. If your answer is negative use “minus sign”.
(a) Use the empirical rule to calculate the percentage of individuals who sleep between 4.9 and 9.7 hours per day.
Enter your answer as a percentage.
%
(b) What is the z-value for an adult who sleeps 8 hours per night?
(c) What is the z-value for an adult who sleeps 6 hours per night?
Using the Empirical Rule and z-scores, we have that:
a) 95% of individuals who sleep between 4.9 and 9.7 hours per day.
b) Z = 0.58.
c) Z = -1.08.
What does the Empirical Rule state?It states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.Approximately 95% of the measures are within 2 standard deviations of the mean.Approximately 99.7% of the measures are within 3 standard deviations of the mean.In item 2, both 4.9 and 9.7 are 2.4 hours from the mean, that is, 2 standard deviations, hence 95% of individuals who sleep between 4.9 and 9.7 hours per day.
What is the z-score formula?The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
For this problem, the mean and the standard deviation are given as follows:
[tex]\mu = 7.3, \sigma = 1.2[/tex]
The z-score for an adult who sleeps 8 hours per night is:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (8 - 7.3)/1.2
Z = 0.58.
The z-score for an adult who sleeps 6 hours per night is:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (6 - 7.3)/1.2
Z = -1.08.

Suppose a stock is selling on a stock exchange for 6 3/4 dollars per share. If the price increases 3/4 per share, what is the new price of the stock? Leave your answer as a proper fraction or mixed number.
Step-by-step explanation:
If the price increases 3/4 per share, the new price of the stock =
6¾ + ¾ =
27 /4 + ¾ =
30 /4 =
15/2 or 7½
The new price of the stock which increases 3/4 per share is $ 7 1/2.
Given data:
A stock is selling on a stock exchange for 6 3/4 dollars per share.
If the price of the stock increases by 3/4 dollars per share, you can add 3/4 to the current price of 6 3/4 dollars per share:
6 3/4 + 3/4
To add the whole numbers and fractions separately:
6 + 0 + 3/4 + 3/4
Adding the whole numbers and fractions:
6 + 1 1/2
A = 7 1/2
Hence, the price of the new stock is $ 7 1/2

-50 -50 subtract 50 from both sides, 50's cancel out from the left.
___________ solve for 101 - 50.
-3x = 51
___ ___ divide -3 on both sides, -3's cancel out on the left.
-3 -3 solve for 51 ÷ -3.

5. Victoria sells different sizes of homemade candles.
• Small candles cost the least and sell for $5 each.
• Extra-large candles cost the most and sell for $20 each,
Yesterday Victoria sold a total of 4 candles, including 1 small candle and 1 extra-large candle.
Which could be the total amount Victoria earned from selling candles yesterday?
A. $20
B. $25
C. $50
D. $85
Answer:
Hello! Your answer is C. $50!
Step-by-step explanation:
The problem says Victoria sold a TOTAL of 4 candles. 2 of them are given. If you add up a small and XL candle, its 25. So, you have to try to add 25 and a combinations of small and/or XL candles. When you add one small and one XL, you get 50. Since $50 is the only amount listed that is correct, it would be your answer. Hope this helps!

A right triangle has a leg that is 2.70 m long and a hypotenuse that is 7.76 m long. What is the length of the other leg of the triangle in meters using the rules for significant digits?
Applying the Pythagorean Theorem and using the rules of significant digits, the length of the other leg of the right triangle is approximately 2.61 meters.
Recall:
Pythagorean Theorem is given as: [tex]a^2 + b^2 = c^2[/tex]a and b are the two other legs of a right-angled triangle, while c is the hypotenuse.Using the Pythagorean Theorem, we are going to find the length of the other leg of the triangle that has:
a = 2.70 m (a leg)c = 7.76 m (hypotenuse)Substitute and find the value of b (the other leg).[tex]2.27^2 + b^2 = 7.76^2\\\\b = \sqrt{7.76^2 - 2.27^2} \\\\b = 2.607[/tex]
Therefore, applying the Pythagorean Theorem and using the rules of significant digits, the length of the other leg of the right triangle is approximately 2.61 meters.
