If a bat and ball costs $1:10
And the bat costs $1 more than the ball
How much does the ball cost?
Answers
x + y = 1.10
x = y + 1
y + 1 + y = 1.10
2y + 1 = 1.10
2y = 1.10 - 1
2y = 0.10
y = 0.10/2
y = 0.05 <=== the ball
x = y + 1
x = 0.05 + 1
x = 1.05 <== the bat

Answers
Rory is staying in a cabin on a hill 300 feet above sea level. She walks down the hill to the water’s edge. The equation of her average change in elevation over time is e = 300 – 10t, where t is the time in minutes since she left the cabin, and e is her elevation with regard to sea level. Which values are viable points, and what are their values in the table relating t and e?
Answers
Rory's change in elevation over time is described by the equation e = 300 - 10t. Viable points are (0, 300), (10, 200), (20, 100), and (30, 0) feet, indicating that she reaches sea level after 30 minutes.
Understanding Rory's Change in Elevation:
Rory is walking down a hill from a cabin that is 300 feet above sea level. The equation describing her elevation over time is given by e = 300 - 10t, where e represents elevation regarding sea level, and t is the time in minutes since she started her journey.
Calculating Elevation Points:
To determine the viable points, we'll plug in different values of t into the equation to get corresponding values of e:
When t = 0,
e = 300 - 10(0) = 300 feet
When t = 10,
e = 300 - 10(10) = 200 feet
When t = 20,
e = 300 - 10(20) = 100 feet
When t = 30,
e = 300 - 10(30) = 0 feet
These values suggest that at t = 30 minutes, Rory reaches sea level.
Creating a Table:
The viable points and their corresponding values of e can be summarized in the following table:
(t = 0, e = 300 feet)
(t = 10, e = 200 feet)
(t = 20, e = 100 feet)
(t = 30, e = 0 feet)

What is the improper fraction?A fraction with a numerator greater than or equal to the denominator is said to be improper. The denominator is the lower number, and the numerator is the top number. When you have wholeness or more than one whole, you can have improper fractions. Here are a few instances of incorrect fractions:
7/5 18/18 100/13
We can see the number of pieces we have in the numerator and the number of parts we are dividing by in the denominator. In the case of an improper fraction, like the first one mentioned above, there are seven parts, each of which is a fifth of the whole.

125 students have volunteered to be on the prom committee. 2 of those students will be randomly chosen to win free tickets to the prom. How many different ways can the winners be chosen?
Answers
Final answer:
There are 7,750 different ways the two winners can be chosen from the 125 students volunteering for the prom committee, calculated using the combination formula C(n, k) = n! / (k!(n-k)!).
Explanation:
To determine how many different ways the two winners can be chosen from the 125 students, we need to use the concept of combinations, because the order in which we choose the winners doesn't matter. The formula for combinations is given by:
C(n, k) = n! / (k!(n-k)!)
where:
n represents the total number of items,
k represents the number of items to choose.
For this situation:
n = 125 (total students),
k = 2 (winners to choose).
Therefore,
C(125, 2) = 125! / (2!(125-2)!)
= 125! / (2! * 123!)
= 125 * 124 / (2 * 1)
= 7750
So, there are 7,750 different ways the winners can be chosen to win free tickets to the prom.

10x = 1.777777...
And then subtract x from 10x and then you get 1.6.
So that means that

and 1.7777... - 0.17777... = 1.6

Problem:
Solve:
5z+7=32
Please SHOW ALL YOUR WORK! (P.S. please show your work clearly, because I will need it for other problems! Thanks!)
Answers
5z+7-7=32-7
5z/5=25/5
z=5
1) You have to try to get z by itself, so that means isolating 7 and 5.
5z + 7 = 32
5z - 7 - 7
----------------
5z = 25
2) Whatever you do to one side, you do to the other. So you subtracted 7 to 7 to isolate 7, and you would subtract 7 to 32 as well. And that will leave you with 5z = 25.
3) Whenever there are a number and a variable next to it, it symbolizes multiplication. (5 x z = 5z) So in order to isolate 5z without taking away your variable, you would have to divide 5 from 5, and also 25.
5z = 25
__ ___
5 5
____________
z = 5
____________________________________________________________
So, the steps are to write the equation out.
Combine any like terms, if there is any. (Ex. 5x + 3 + 52x + 39 {you can combine 5x and 52x because they are like terms, meaning they are alike. Other words are simplifying. (57x) :)}[and you can combine 3 and 39 since they are alike too. (42)])
Then, you add/subtract ON BOTH SIDES!
And after that, you finish it off by multiplying/dividing ON BOTH SIDES.
And how you know if you subtract or add is that if it is positive or negative.
Ex. +5 ( you would subtract in order to get it to zero. So -5)
Ex. -5 ( you would add in order to get is to zero. so +5)
And how you know it's multiplication or division.
Ex. 5x (5 * x = 5x, so you would divide by 5 to get zero, and divide 5 ON BOTH SIDES)
Ex. \frac{x}{5} [/tex] ( you would have to multiply 5 from top and bottom and ON BOTH SIDES)

The National Safe Kids Campaign and Bell Sports sponsored a study that surveyed 8,159 children ages 5 to 14 who were riding bicycles. Approximately 2/5 of the children were wearing helmets, and of those, only 13/20 were wearing the helmets correctly. About how many of the children were wearing helmets correctly?
Answers
Final answer:
To find the number of children wearing helmets correctly, multiply 2/5 by 8,159 to get the number of children wearing helmets, then multiply that result by 13/20 to get the number of children wearing helmets correctly, which is approximately 2,134.
Explanation:
The student's question involves mathematical computations to determine how many children were wearing helmets correctly out of a surveyed group. The data provided indicates that 2/5 of the 8,159 children were wearing helmets, and out of those, 13/20 were wearing the helmets correctly. To calculate the exact number of children wearing helmets correctly, we should perform the following steps:
Calculate the number of children wearing helmets: (2/5) × 8,159 = 3,263.6, which we can round down to 3,263 children, since we cannot have a fraction of a child.
Calculate the number of children wearing helmets correctly: (13/20) × 3,263 = 2,134.95, which we can round down to 2,134 children wearing helmets correctly.
Therefore, approximately 2,134 children were wearing helmets correctly.

4. Describe the number set(s) the number belongs to: −√17
Answers
-√17 belongs in only one number set: irrational.
The number -√17 is an irrational number and is part of the set of real numbers.
Explanation:The number -√17 belongs to the set of real numbers. However, because this number is the square root of a positive number (17) and is multiplied by negative sign, it is not a rational number, but rather an irrational number.
It is part of the real numbers because the set of real numbers includes all numbers that can be plotted on a number line, including integers, rational numbers (numbers that can be expressed as a quotient of two integers), and irrational numbers (numbers that cannot be expressed as a quotient of two integers).
It is specifically an irrational number because the square root of 17 is a non-repeating, non-terminating decimal, and when we multiply this by a negative sign, the numerical value itself does not change, only its direction on the number line.
