Tom likes to go over to his friend's house almost every night to play video games. They usually spend 3 hours a night playing the video game together. Last week, they spent a total of 15 hours playing the video game. If Tom went over every night, he would spend 21 hours playing the video game. Also, Tom's friend's mom gives Tom two cookies each time he is there. How many cookies does Tom get last week?
Answer:
it is 10
Step-by-step explanation:
Answer:
he got ten cookies because since they play for 3 hours a night you do 15/3 to get 5 nights. since his friends gets 2 cookies everyday he is there 5*2 is 10 cookies last week

Simplify the expression.
4 (2m – 6) – 3p – 2m + 8
-------------------------------------------------------------------
4 (2m – 6) – 3p – 2m + 8
Expand 4 (2m – 6):
8m - 24– 3p – 2m + 8
Simplify 8m - 24– 3p – 2m + 8:
Group like terms:
8m - 2m - 3p - 24 + 8
Add similar elements:

While shopping for clothes, Daniel spent $34 less than 3 times what Jaclyn spent. Daniel spent $14. Write and solve an equation to find how much Jaclyn spent. Let x represent how much Jaclyn spent.
___x - ___ = ___
Jaclyn spent $____
Answer: Jaclyn spent $48
Step-by-step explanation:
3x - 34 = 14
3x = 14+34
X = 48/3 = 16
Answer:
spent 48$

The standard configuration for an Arizona license plate is 3 digits (0 - 9) followed by 3 letters (of 26). If you can not repeat digits or letters, how many plates (NO COMMAS NEEDED) can be made?
Answer:
11232000 plates
Step-by-step explanation:
To find the number of plates that can be made, we just need to check for each space filled how many possible values it can take:
We have 3 digits that can not repeat, so the first digit has 10 possible values (all digits from 0 to 9), the second digit has 9 possible values (as one is already taken) and the third digit has 8 possible values.
For the letters, the first one has 26 possible values, the second one has 25 and the third one has 24.
So the number of different plates is the product of all these possibilities for each digit and letter:
10 * 9 * 8 * 26 * 25 * 24 = 11232000 plates
Janitors at Strickland High School empty 25 trash cans each day. The design of
each trash can is shown below.
Height- 4.5 inches
Length- 3 inches
Width- 2 inches
What is the total volume of trash that the janitors empty each day?
Round to the nearest tenth and don't forget to include units. The tick mark
on the numbers represents inches.
Answer: 675 cubic inches of trash
Step-by-step explanation:
Hi, to answer this question, first, we have to calculate the volume of each trash can :
Volume of a rectangular prism: width x length x height
Replacing with the values given:
V = 2 x 3 x 4.5= 27 cubic inches
Since there are 25 trash cans every day, we have to multiply the volume of each one by 25.
27 x 25 =675 cubic inches of trash

3. Give two systems of equations that would be easier to solve by substitution
than by elimination. Then give two systems that would be easier to solve with
elimination. Finally, explain how you decide whether to use elimination or
substitution to solve a system.
Answer:These techniques for elimination are preferred for 3rd order systems and higher. They use "Row-Reduction" techniques/pivoting and many subtle math tricks to reduce a matrix to either a solvable form or perhaps provide an inverse of a matrix (A-1)of linear equation AX=b. Solving systems of linear equations (n>2) by elimination is a topic unto itself and is the preferred method. As the system of equations increases, the "condition" of a matrix becomes extremely important. Some of this may sound completely alien to you. Don't worry about these topics until Linear Algebra when systems of linear equations (Rank 'n') become larger than 2.
explanation Step-by-step explanation:ust to add a bit more information, "Elimination" Can have a variety of other interpretations. Elimination techniques typically refer to 'row reduction' to achieve 'row echelon form.' Do not worry if you have not heard of these terms. They are used in Linear Algebra when referring to "Elimination techniques"

Substitution is the preferred method for 2 equations in 2 unknowns. The constants are unimportant other than having a non-zero determinant. It is always easy to find multiplicative factors using LCMs of one variable or the other to allow substitution into the other equation:
Example:
4X + 5Y = 9
5X - 4Y = 1
Notice that 20 is a LCM of either the X or Y variable. So multiply the first by 4 and the second by 5 and then adding the two (Y's will drop out allowing for substitution)
4(4X + 5Y = 9)
5(5X - 4Y = 1)
Multiplying to produce the LCM factors:
16X + 20Y = 36
25X - 20Y = 5
Adding the equations
41X = 41
X = 1
Substitution into either equation yields
Y = 1

Doug records how many miles and how long he rides his bike each day on a scatter plot.
Doug analyzes his data on the scatter plot and concludes that the more time he rides his bike, the slower his speed is. In two or more complete sentences, explain why or why not it is possible for Doug to make his conclusion based on his data.
Answer:
the plot shows he had a speed of 0.20 miles but the longer he travels the slower he gets, so his last speed is 0.17 miles a minute

7. The original price of a bicycle is $700. It is discounted by 50%. What is the sales price of
the bike?
Answer:
$350.
Step-by-step explanation:
50% translates over to 1/2, so you take the price of $700 and multiply it by 1/2. You then get $350, which is half of $700.

explain how finding the volume of a cylinder is similar to finding the volume of a prism
Answer:
Finding the volume of a cylinder is similar to finding the volume of a prism because they share the same formula, that is:
V = base area x height
Hope this helps!
:)
Answer:
Volume of a prism is base area × height
Base of a cylinder is a circle,
Base area = pi× r²
Volume of cylinder = pi × r² × h
Which is the same as base area × height

Completed the table of values using the function y=4x-3. Graph the function on the coordinate plane.
Answer:
Step-by-step explanation:
substitue values in the table into the equation.
x = 2, then y = 4(2)-3 =>
y= 5
y = -3, then -3 = 4x-3 =>
x = 0
x = -1, then y = 4(-1) - 3 =>
y = -7
x = 3, then y = 4(3) -3 =>
y = 9
y = 1, then 1 = 4x - 3 =>
x = 4
now plot all of these points and create a line from them

Answer:
d = 52
Step-by-step explanation:
The two angles form a straight line so they are supplementary
Supplementary angles add to 180
d+128 = 180
Subtract 128 from each side
d+128-128 = 180-128
d = 52
Answer:
52
Step-by-step explanation:
so to solve this one, you have to get the value of d.
for this you need to first subtract the given angle from 180.
180-128=52
that is the value of d :) if u need any more help post a question, ill follow you!
Janet saved $3500 in 2007. If each year after
this she saves $750 more than the year before,
how much will she save in 2012?
(A) $5750
(B) $6500
(C) $7250
(D) $8000
(E) $8750
Answer:
7250
Step-by-step explanation:
The equation would be as follows
3500+750x=y
Between 2012 and 2007, there are 5 years, thus x=5
3500+750(5)=7250

Answer:
X = 7
-4x + 2(5x - 6) + 2x = 44
GROUP LIKE TERMS
-4x + 2x = -2x
-2x + 2(5x -6) = 44
-2x + 10x - 12 = 44
8x - 12 = 44
ADD 12 ON BOTH SIDES
8x = 56
DIVIDE 8 ON BOTH SIDES
x = 7

What is the distance from the right center field fence to third base? Show all of your work and round
your answer to the nearest tenth of a foot
Answer:
[tex]381.5\,\,\,ft[/tex]
Step-by-step explanation:
Given: Figure
To find: distance from the right center field fence to third base
Solution:
In a right angled triangle,
using Pythagoras theorem, square of hypotenuse is equal to sum of squares of base and perpendicular.
In ΔBAC,
[tex]BC^2=AB^2+AC^2\\(392)^2=x^2+(90)^2\\153664=x^2+8100\\153664-8100=x^2\\145564=x^2\\\sqrt{145564}=x\\381.5\,\,\,ft=x[/tex]
So,
distance from the right center field fence to third base is 381.5 foot.
