Here are three stories:
• A family buys 6 tickets to a show. They also pay a $3 parking fee. They spend $27 to see the
show.
• Diego has 27 ounces of juice. He pours equal amounts for each of his 3 friends and has 6
ounces left for himself.
• Jada works for 6 hours preparing for the art fair. She spends 3 hours on a sculpture and
then paints 27 picture frames.
Here are three equations:
• 3x + 6 = 27
• 6x +3=27
• 27x + 3 = 6
a. Decide which equation represents each story. What does x represent in each equation?
b. Find the solution to each equation. Explain or show your reasoning,
c. What does each solution tell you about its situation?
Answer:
1)
a) 6x+3 = 27
b) x=4
c) We know that x is price of each ticket, so The price of each ticket is $4. They bought 6 tickets, so total cost of ticket = 24 and $3 for parking so, total money spent = $27.
2)
a) 3x + 6 = 27
b) x= 7
c) We know that x is amount of juice poured, so 3 friends of Diego will get 7 ounces of Juice, while Diego will get 6 ounces of juice.
3)
a) 27x + 3 = 6
b) x= 1/9
c) We know that x is time spend on each picture, so Jada spend 1/9 hour on each picture
Step-by-step explanation:
1. A family buys 6 tickets to a show. They also pay a $3 parking fee. They spend $27 to see the show.
a) Decide which equation represents each story. What does x represent in each equation?
Let x be price of one ticket.
The equation will be: 6x+3 = 27
b. Find the solution to each equation. Explain or show your reasoning,
Now solving the equation:
6x+3=27
6x=27-3
6x=24
x=24/6
x=4
So, we get x = 4
c. What does each solution tell you about its situation?
We know that x is price of each ticket, so The price of each ticket is $4. They bought 6 tickets, so total cost of ticket = 24 and $3 for parking so, total money spent = $27.
2. Diego has 27 ounces of juice. He pours equal amounts for each of his 3 friends and has 6 ounces left for himself.
a) Decide which equation represents each story. What does x represent in each equation?
Let x be amount of juice poured.
The equation will be: 3x+6 = 27
b. Find the solution to each equation. Explain or show your reasoning,
Now solving the equation:
3x+6=27
3x=27-6
3x=21
x=21/3
x=7
So, we get x = 7
c. What does each solution tell you about its situation?
We know that x is amount of juice poured, so 3 friends of Diego will get 7 ounces of Juice, while Diego will get 6 ounces of juice.
3. Diego has 27 ounces of juice. He pours equal amounts for each of his 3 friends and has 6 ounces left for himself.
a) Jada works for 6 hours preparing for the art fair. She spends 3 hours on a sculpture and then paints 27 picture frames.
Let x be time spend on each picture frame.
The equation will be: 27x+3=6
b. Find the solution to each equation. Explain or show your reasoning,
Now solving the equation:
27x+3=6
27x=6-3
27x=3
x=3/27
x=1/9
So, we get x = 1/9
c. What does each solution tell you about its situation?
We know that x is time spend on each picture, so Jada spend 1/9 hour on each picture

ABD=70 CBD=5x+13 ABC=3x+33
The value of x of the straight line will be 8° by using straight line property.
We are given the measures of 3 angles that form a straight line.
∠ ABD = 70°
∠ CBD = 5 x + 13
∠ ABC = 3 x + 33
We need to find the value of x.
We know that the straight line property states that the sum of measures of all the angle of the line should be 180°.
So, we get that:
∠ ABD + ∠ CBD + ∠ ABC = 180°
Substituting the values of the angles, we get that:
70 + 5 x + 13 + 3 x + 33 = 180
8 x + 116 = 180
8 x = 180 - 116
8 x = 64
x = 64 / 8
x = 8°
Therefore, we get that, the value of x of the straight line will be 8° by using straight line property.

Boris filled his gas tank three times last week. Here are the amounts of gas he bought (in gallons).
9.94, 1, 19.1
What is the total amount of gas Boris bought last week?
Answer:
30.04
Step-by-step explanation:
You could do this the simple way which is to first grab two numbers in any order and add them together, and after you do that you can add the result to the remaining number or numbers that remain. 9.94 plus 1 is 10.94, and 10.94 plus 19 is 29.94, lastly the .1 from the 19 which finally leads us to the answer of 30.04 gallons that Boris bought last week

Step-by-step explanation:
California, the most populous state, has approximately 40,000,000 people living in it. The population of the entire United States is about 3E8 people. About how many times greater is the population of the United States than the population of California?
State operation used and write answer in proper scientific notation (can use e)
Answer: 7.5 E 0
This is the same as saying 7.5 * 10^0
Both of these values convert to the number 7.5; meaning that the population of the US is about 7.5 times greater than the population of CA.
==========================================================
Work Shown:
40,000,000 = 40 million
40,000,000 = 4.0 * 10^7
Note how we move the decimal 7 spots to the right to go from 4.0 to 40,000,000
so the 7 in 10^7 tells us how many spots to move the decimal point in the base number 4.0
The number 4.0*10^7 can be condensed to 4E7. The "E" represents "times 10 to the"
As another example, "3E8" means "3 times 10 to the 8th power" which becomes 3.0*10^8 = 300,000,000 = 300 million
--------------------------
We have these two facts
x = Population of CA = 4 E 7 = 4*10^7y = Population of US = 3 E 8 = 3*10^8We'll divide the two populations to get
y/x = (3E8)/(4E7)
y/x = (3*10^8)/(4*10^7)
y/x = (3/4)*10^(8-7)
y/x = 0.75*10^1
y/x = 7.5
We can see that the population of the US is roughly 7.5 times greater compared to the population of CA.
Convert 7.5 to scientific notation, and we get
7.5 = 7.5*1 = 7.5 * 10^0 = 7.5 E 0
Keep in mind that these are population estimates, and populations change over time.

One rollercoaster starts 72 feet above the ground and descends to ground level over a 24-foot horizontal distance. A second rollercoaster starts 39 feet above the ground and descends to ground level over a 13-foot horizontal distance. Are the descending parts of these rollercoasters parallel?
A.
Yes; when descending, the rollercoasters have the same slope.
B.
No; the first rollercoaster has a greater slope than the second rollercoaster.
C.
No; multiplying the slopes of the two rollercoasters does not give a product of –1.
D.
The two roller coasters do not have the same horizontal change, so they cannot be compared.

Answer:
C) a = 3√10; b = 3√5
Step-by-step explanation:
The side ratios in an isosceles right triangle are 1 : 1 : √2. This is a fact worth remembering. You know the triangle is isosceles because both acute angles are 45°, which means both legs are the same length.
If the leg lengths are 1, the Pythagorean theorem tells you the hypotenuse is ...
c^2 = a^2 + b^2 . . . . . . for legs a, b, and hypotenuse c
c^2 = 1^2 + 1^2 = 2
c = √2
This tells you the leg : leg : hypotenuse ratios are as shown above.
__
What that means here is that b = 3√5, the same length as the one shown. It also means that ,,,
a = (3√5)(√2) = 3√(5·2)
a = 3√10
The only answer choice with the correct value of 'a' is (C).
a = 3√10, b = 3√5
