Answer:
Y=8
Step-by-step explanation:
The difference between the number Alice hit and 6 is X - 6. Twice that would be 2(X-6). So Y = 2(X-6). We also know that X + Y = 18 so we have 2 equations:
Y = 2(X-6)
X+Y = 18
Let's take the second equation and solve for Y in terms of X
Y = 18 - X
Now take that result and substitute that back into the first equation that starts with Y, because now you know that Y is also equal to 18 - X, now you have:
18 - X = 2(X - 6)
Let's solve for X
18 - X = 2X - 12
18 - 3X = - 12
- 3X = - 30
X = 10 <--number of home runs Alice Hit
That leaves us with Y = 8 <---number of home runs Peter hit
Go back to the original question and make sure the answer fits. The difference between 10 and 6 is 4 and twice that is 8, the number Peter hit. 10 + 8 = 18. Good to go!

how do you differentiate linear equation from those equatipn which are not linear?
Answer:
the x
Step-by-step explanation:
Looking at the x in an equation can reveal its shape. A linear graph can look like y=x, y=mx, y=mx+b (m being any number).
When you look at graphs that aren't linear, the x doesn't stand alone in the equation.
Parabolas have a y=x^2 equation. Cubic graphs are y=x^3. They have something attached to the x.
To see all the different kinds of equations and what their graphs look like you can search up "parent functions" and all the basic formulas show up.
what is a 60% out of 100
━━━━━━━☆☆━━━━━━━
▹ Answer
60% of 100 is 60
▹ Step-by-Step Explanation
60% of 100:
- You can write this as a fraction or decimal. In this case, both of them will work just fine but we can go with fractions.
60% is written as 6/10 as a fraction or 0.6 as a decimal.
[tex]\frac{6}{10} * 100\\ =\frac{600}{10} \\= 60[/tex]

Kenny had a total of 140 minutes to read, do homework, and play video games.
He spent x minutes reading.
He spent 2(x+5) minutes doing homework
He spent 25 minutes playing video games
How many minutes did Kenny spend reading
Help fast Please
Answer: 35minutes
Step-by-step explanation:
Minutes spent reading = x
Minutes spent doing homework =2(x+5) = 2x + 10
Minutes spent playing video games = 25minutes
Total minutes used = 140 minutes
x + 2x + 10 + 25 = 140
3x + 35 = 140
3x = 140 - 35
3x = 105
x = 105/3
x = 35 minutes
If the measure of one interior angle of a regular polygon is 156° , how many sides does it have?
Answer:
The polygon has 15 sides
Step-by-step explanation:
Angles in a Regular Polygon
A polygon with n sides has a total sum of internal angles equal to 180°(n-2). This means that in a regular polygon, each angle measures
[tex]\displaystyle \frac{180(n-2)}{n}[/tex]
The regular polygon's interior angle is 156°, thus
[tex]\displaystyle \frac{180(n-2)}{n}=156[/tex]
Multiply by n:
[tex]180(n-2)=156n[/tex]
Operate:
[tex]180n-360=156n[/tex]
Reducing:
[tex]24n=360[/tex]
Solving:
[tex]n=15[/tex]
The polygon has 15 sides

During a cat food sale, a pet store sells 220 cans of cat food. At the end of the
sale, the store has 80% of the original number of cans of cat food. How many
cans of cat food are left?
Answer:
44 cans
Step-by-step explanation:
To find 80%, just multiply 220 by 0.8
220 x 0.8 = 176.
Now, take 220 and subtract 176.
220-176 = 44
44 cans are left over. Hope this helps.
if 6+x=13, then find the value of 8x-31.
Answer:
The answer is 25.
Step-by-step explanation:
First, you solve 6+x=13. Minus 6 from each side. You get x=7.
Next, plug x into the equation 8x-31. You get 8(7)-31. Solve 56-31, which you then get 25.
Find values for p and q so that x = 4 is the only solution to the equation.
px - 8 = 5x + 9
Answer:
Step-by-step explanation:
Given the equation px - 8 = 5x + 9, we can only find the value of p when x = 4.
To get p, we will substitute x = 4 into the expression as shown:
p(4)-8 = 5(4)+9
4p - 8 = 20+9
4p - 8 = 29
4p = 29+8
4p = 37
p = 37/4
p = 9 1/4
Hence the value of p so that x = 4 is the only solution is 9 1/4

An electrician charges a base fee of $60 plus $50 for each hour of work. The minimum the electrician
charges is $160. Create a table that shows the amount the electrician charges for 1, 2, 3, and 4 hours of
work. Determine the domain and range of the relation in context and explain whether or not this
represents a function.

160-110=50

The electrician charges $12.50 per hour, or $50 for 4 hours.
This is not a function for the fact that 1, 2, 3, and 4 all go to the same value.
Which expression is equivalent to 32−−√−3x2–√+38–√?
Answer:
8
Step-by-step explanation:
The indices question is not properly written. Find the correct expression in the attachment
[tex]-32^{\frac{3}{5} }[/tex] [tex]= (\sqrt[5]{-32})^3[/tex]
for [tex]\sqrt[5]{-32}[/tex]
we need a value to multiply 5 times that will give us -32;
[tex]\sqrt[5]{-32} = -2[/tex]
substitute the answer in the original expression
[tex]= (\sqrt[5]{-32})^3\\= 2^3[/tex]
Evaluate the resulting indices
[tex]2^3 = 8\\[/tex]
Hence the expression [tex]-32^{\frac{3}{5} }[/tex] is equivalent to 8

Carrie needs 4 1/2 cups of flour for a recipe. She can only find a 1/4 cup measuring cup. How many times will Carrie need to fill this measuring cup to have enough flour for the recipe?
Answer:
Carrie will need to fill the measuring cup 18 times to have enough flour for the recipe.
Step-by-step explanation:
There are four 1/4's in one cup and two 1/4's in a 1/2 cup. So 4 times 4 equals 16 and 2 times 1 is 2. Add those together and you get 18 times. Sorry if it was confusing.
Aylor bought 6 tickets to a movie. The price of each ticket was the same. After he bought the tickets, his account balance showed a change of −$68.04. What would have been the change to Taylor's account balance had he only bought 1 ticket to the movie? (5 points)
Answer:
-$11.34
Step-by-step explanation:
Cost of 6 tickets = $68.04
Aylor's account balance showed a change of −$68.04
Cost of 1 tickets = cost of 6 tickets / 6
= $68.04 / 6
= $11.34
change to Taylor's account balance had he only bought 1 ticket to the movie will be -$11.34
