At an amusement park you get five points for each bull’s eye you hit, but you loose 10 points for every miss. After 30 tries, Yolanda lost 90 points. How many bull’s eyes did she hit?
Answers
Answer:
21
Step-by-step explanation:
14 bull's eyes (or hits) and 16 misses.
The 14 hits earned her five points each, or a total of 70 points.
The 16 misses cost ten points each, or a total of 160 points lost.
14 + 16 = 30
70 - 160 = -90
SOLUTION:
points = 5H - 10M = -90 where H = hits and M = misses
tries = H + M = 30 therefore
H = 30 - M
and 5(30 - M) - 10M = -90
150 - 5M -10M + 90 = 0
240 -15M = 0
15M = 240
M =16
H = (30 - M) = 16

When D’Ante looked at the car lot, he noticed that for every 2 red vehicles, there were 6 grey vehicles. If there are 144 total vehicles in the parking lot, how many of them are red? How many are grey?
Answers
Answers:
36 red cars108 grey cars========================================================
Work Shown:
The ratio 2 red : 6 grey reduces to 1 red : 3 grey when we divide both parts by 2. For every 1 red car, there are 3 grey cars. There are triple as many grey compared to red.
Let x be the number of red cars. Since there are 3 times as many grey cars, this means 3x represents the number of grey cars.
The total number of cars can be represented by the expression x+3x = 4x
Set this equal to the total number of cars (144) and solve for x
4x = 144
x = 144/4
x = 36
There are 36 red cars.
Subtract that value from 144 to find 144-36 = 108 grey cars.
----------------------------------------
An alternative way to solve:
(2 red)/(6 grey) = (x red)/( (144-x) grey)
2/6 = x/(144-x)
2(144-x) = 6x .... cross multiply
2*144 - 2*x = 6x
288 - 2x = 6x
288 = 6x+2x
288 = 8x
8x = 288
x = 288/8
x = 36
If there are 144 vehicles in the parking lot, then 36 cars are red.
Also, 144 - x = 144 - 36 = 108 cars are grey.
108 grey cars

Mr. Paulsen challenges Olivia and Angelica to move figure ABCDE onto figure A"B"C"D"E" using a series of two different transformations. They give two different answers.
Answer the questions to investigate ways to transform ABCDE.
1. Olivia finds a combination of two different transformations that moves ABCDE onto A"B"C"D"E". What is one way she might have done this?
2. Angelica reflects ABCDE over the y-axis and translates it up 8 units. Does her transformed figure match A"B"C"D"E"? If not, describe how her transformed figure compares to A"B"C"D"E".
3. Michael says he can move ABCDE onto A"B"C"D"E" with one transformation by translating ABCDE diagonally so that it moves 8 units up and 10 units right. Is he correct? Explain why or why not.
Answers
Problem 1
One method Olivia could have used is to reflect over the x axis and then translate 10 units to the right.
Let's apply these set of steps to point C.
C = (-2,-4)
C' = (-2,4) after reflecting over the x axis; y coordinate flips in sign
C'' = (8,4) after shifting to the right 10 units; add 10 to the x coordinate
Point C(-2,-4) moves to C''(8,4) which is shown in the diagram. I'll let you check the other four points.
-----------
Another method Olivia could have used is to shift to the right 10 units first, then reflect over the x axis. In this case, the order doesn't matter. Though for some other combinations of transformations, order does matter.
============================================================
Problem 2
Reflecting over the y axis will have the point (x,y) turn into (-x,y). Only the x coordinate changes, and we flip the sign here. The y coordinate stays the same.
A point like C(-2,-4) becomes C'(2,-4) after the y axis reflection. Shifting up 8 units means we add 8 to the y coordinate to arrive at C''(2,4) but this does not match what the diagram shows. Therefore, Angelica's method is incorrect.
You should find other inconsistencies for the other four points as well.
============================================================
Problem 3
Michael's method isn't correct either. He does not apply an x axis reflection and instead relies entirely on translations to move ABCDE to A''B''C''D''E''
At a quick glance, it looks like Michael may be correct. But upon a much closer look, you'll see that things don't line up perfectly.
Instead of point C, we'll pick on point D this time.
D is located at (-6,-2). If we shift up 8 units, then we add 8 to the y coordinate to get to D'(-6,6). Then add 10 to the x coordinate to shift 10 units to the right. This leads us to D''(4,6).
However, the diagram shows D'' is actually at (4,2)
I'll let you check the other points. You should find that only points C and E go to the correct locations, but the other points do not. Again, this is because Michael did not apply an x axis reflection. His figure of A''B''C''D''E'' is upside down compared to what it should be.
============================================================
To summarize, the methods described in problem 1 are the correct way to get ABCDE to move to A''B''C''D''E''. If Olivia followed either of those two methods, then she is correct. Both Angelica and Michael have incorrect methods.

can you mark me brainliest please
Answer: B, C , and E are the answers
Step-by-step explanation:
First solve the expressions by breaking it down.
2h + g Nothing can be done to this expression because it is already broken down.
4(2h + g) Apply the distributive property to break it down.
4(2h) + 4(g)
= 8h + 4g
4h + 4h + 3g + g Combine like terms to break this one down
(4h + 4h) + (3g + g)
= 8h + 4g
1/4(2h + g) Apply the distributive property to break it down.
= 1/2h + 1/4g
2(4h + 2g) Apply the distributive property to break it down.
= 8h + 4g
1/8(8h + 4g) Apply the distributive property to break it down.
1h + 1/2g

Module Six Project Option 1

Sarah’s neighbor offers to pay her $5 for every shark tooth she finds on the beach. After collecting only three shark’s teeth, Sarah decides to share the opportunity with her friend John. Sarah can find shark teeth twice as fast as John, but she can earn even more money with his help.
Sarah can use the expression 5(2j + 3 + j) to represent the amount of money she can earn.
Part 1: Writing Expressions
Write an expression that looks like Sarah’s expression: 5(2j + 3 + j). Replace the coefficients so that your expression is not equivalent. You may use any number that you choose to replace the coefficients. Be sure to leave the variables the same. For example, 8(3j + 7 + 3j) looks like Sarah’s expression but is not equivalent.
Translate the algebraic expression you created in Question 1 to a verbal expression.
Part 2: Writing Equivalent Expressions
You will now use mathematical properties to create two expressions that are equivalent to the expression you created in Question 1. Make sure you show all steps in your work.
Use either the commutative property or combine like terms to create an equivalent expression.
Use the distributive property to create an equivalent expression.
Pick a number from 1 to 10. Use that number to verify your three expressions (the original, the one from 3a, and the one from 3b) are equivalent by substituting it into each expression. Show all your work for complete credit.
Part 3: Finish the Story
Write a few sentences to end Sarah’s story. How many shark teeth did she find? How many shark teeth did John find? How much money did Sarah earn?
