5. Carlos and Mike are selling cheesecakes for a school fundraiser. Customers can buy pecan
cheesecakes and apple cheesecakes. Carlos sold 1 pecan cheesecake and 4 apple cheesecakes for a total
of $44. Mike sold 14 pecan cheesecakes and 14 apple cheesecakes for a total of $238. Find the cost
each of one pecan cheesecake and one apple cheesecake.
a. Define variables:
b. System:
c. Solve the systems (optional):
Answer:
One pecan costs $8. One apple costs $9.
Step-by-step explanation:
p and a are number of number of pecan and apple sold, respectively.
:::::
"1 pecan cheesecake and 4 apple cheesecakes for $44"
p + 4a = 44
"14 pecan cheesecakes and 14 apple cheesecakes for $238"
14p + 14a = 238
You have a system of two equations in two unknowns:
p + 4a = 44
14p + 14a = 238
:::::
Eliminate the p terms: Multiply the first equation by -14, then add the product to the second equation.
-14p - 56a = -616
14p + 14a = 238
------------------------
-42a = -378
a = (-378)/(-42) = 9
p = 44-4a = 8
One pecan costs $8. One apple costs $9.
Solve the following equations for the given variable.
3x + 2y = 6 for y
Answer:
Answer:
y=3
Step-by-step explanation:
you just need to do 2 divided by 6
Answer: y = -3/2x + 3
Step-by-step explanation:
3x + 2y = 6 First Isolate y by subtracting 3x from both sides
-3x -3x
2y = -3x + 6 Now divide both sides by 2
y = -3/2x + 3

Answer:
The first is true.
8 · 21 = 168
The second is false.
The third is false.
The fourth is true.
Step-by-step explanation:
Answer:
true
168 divided by 21 is 8
true
168 divided by 8 is 21
false
168 divided by 16 is 10.5
false
168 divided by [tex]\frac{1}{8}[/tex] is 21
Step-by-step explanation:
for number one since there 21 cans of soup and 168 oz are used for all cans you would divide 168 by 21 and you get 8 and so on with the rest of the questions !

Describe how a point on a graph is related to a table and an equation that represent the same relationship.
Answer:
because everything is relative to each other.
Step-by-step explanation: Graphing ordered pairs is only the beginning of the story. Once you know how to place points on a grid, you can use them to make sense of all kinds of mathematical relationships. A linear relationship is a relationship between variables such that when plotted on a coordinate plane, the points lie on a line. Let’s start by looking at a series of points in Quadrant I on the coordinate plane. Look at the five ordered pairs (and their x– and y-coordinates) below.

The triangles are similar. Complete the similarity statement
Answer:
ABC
Step-by-step explanation:
Answer:
YZX ~ ABC
Step-by-step explanation:
For Angle Y, there is one curved line, so you must go to the other triangle and find which angle has one curved line too, in this case that is angle A. Then, Angle Z has three curved lines, and in the other triangle, Angle B has three curved lines, so you now have AB, which only leaves C left. So your final answer is ABC.
A coin is flipped 5 times. What is the total possible outcomes or sample space for this event?
Answer:
Step-by-step explanation:
If the spinner has an even number of numbers on it, there will be an equal number of odd and even numbers, meaning that the probability of spinning an odd number is 1 2. This is also the probability of flipping heads on a coin. And so we have: 1 2 × 1 2 × 1 2 = 1 8. If the spinner has an odd number of numbers on it, the probability of spinning an odd number will vary. hope this helped\

3. Maryia wants to save money on a new computer. At the store near her,
the computer she wants is listed at a regular price of $400.00. On
Saturday, the store will have a sale and discount the computer by 1/5 off
the original price. How much will Maryia pay, when she buys the computer
that Saturday? *
A. $320
B. $210
O C. $250
O D. $120
Answer:
A
Step-by-step explanation:
So, what is happening is that the sale would put the computer on 4/5 the original price, since 1/5 of the price is being taken away in the sale.
4 divided by 5 is 0.8, and 0.8 times 400 is 320.
Hope this helps!

find product of 5/12×6
Answer:
2 and 1/2
Result in decimals: 2.5
Step-by-step explanation:
5/12 × 6/1 = 5/2 = 2 and 1/2
Result in decimals: 2.5
Calculation steps:
5/12 × 6/1 = (5 × 6)/(12 × 1) = 30/12
30 ÷ 6 = 5
12 ÷ 6 = 2
= 5/2
= 2 and 1/2
4. The side lengths of a square are each 5p. By adding 1 to the length and subtracting 1 from the width, a rectangle is made. What is the area of the rectangle?
O4p2 - 2
25p2 + 1
25p - 10p - 1
25p2 - 1
Answer:
D. 25p² - 1
Step-by-step explanation:
Each side length of a square = 5p
Length of rectangle = 5p + 1
Width of the rectangle = 5p - 1
Area of rectangle = Length × Width
Area of rectangle = (5p + 1)(5p - 1)
= 5p(5p - 1) +1(5p - 1) (distributive property)
= 25p² - 5p + 5p - 1
Area = 25p² - 1

Answer:
(24x - 48y + 10) / 26 = a
Step-by-step explanation:
-12(-2x+4y) = 26a - 10
24x - 48y = 26a - 10
24x - 48y + 10 = 26a
(24x - 48y + 10) / 26 = a
