Answers
Answer:
1. a) 3x + 21 = 6x - 60
b) x = 27
c) angle measure = 102º
2. a) 12x - 18 = 8x + 10
b) x = 7
c) angle measure = 66º
3. a) 7x + 9 + 5x + 3 = 180 (simplified: 12x + 12 = 180)
b) x = 14
c) 107º; 73º
4. a) 3x + 10 + 3x -28 = 180 (simplified: 6x -18 = 180)
b) x = 33
c) 109º; 71º
5. a) 12x + 15 = 15x
b) x = 5
c) 75º
Step-by-step explanation:
1. a) they're the same angle so set them equal to each other: 3x + 21 = 6x - 60
b) solve from the equation above
3x + 21 = 6x - 60 subtract 3x from both sides
21 = 3x - 60 add 60 to both sides
81 = 3x divide both sides by 3
x = 27
c) plug back into each equation (they should be the same, but do both just to check)
3(27) + 21 = 81 +21 = 102º
6(27) - 60 = 162 - 60 = 102º
2. a) again, they're the same angle measure so set them equal to each other: 12x - 18 = 8x + 10
b) solve the equation for x
12x - 18 = 8x + 10 subtract 8x from both sides
4x - 18 = 10 add 18 from both sides
4x = 28 divide both sides by 4
x = 7
c) plug back into each equation (they should be the same, but do both just to check)
12(7) - 18 = 84 - 18 = 66º
8(7) + 10 = 56 + 10 = 66º
3. a) the sum of the two angles is 180º so 7x + 9 + 5x + 3 = 180
if you want the equation simplified: 12x +12 = 180
b) solve for x, i will be using the simplified equation
12x + 12 = 180 subtract 12 from both sides
12x = 168 divide both sides by 12
x = 14
c) plug into each equation to get the two angle measures
7(14) + 9 = 98 + 9 = 107º
5(14) + 3 = 70 + 3 = 73º
4. a) the sum of the two angles is 180º so 3x + 10 + 3x -28 = 180
if you want it simplified: 6x -18 = 180
b) solve for x, i will be using the simplified equation
6x - 18 = 180 add 18 to both sides
6x = 198 divide both sides by 6
x = 33
c) plug into each equation to get the two angle measures
3(33) + 10 = 99 + 10 = 109º
3(33) - 28 = 99 - 28 = 71º
5. a) they're the same angle measure so set them equal to each other: 12x + 15 = 15x
b) solve for x with the equation above
12x + 15 = 15x subtract 12x from both sides
15 = 3x divide both sides by 3
x = 5
c) plug back into each equation (they should be the same, but do both just to check)
12(5) + 15 = 60 + 15 = 75º
15(5) = 75º

Graph each line. Give the slope-intercept form for all standard form equations.
Answers
Answer:
Slope Intercept Form is y=2x.
Step-by-step explanation:
Since slope-intercept form is y=mx+b, you need to rewrite 2x-y=0 in Slope-Intercept Form.
First, you want to subtract 2x from both sides. That comes out to -y = (-2x.)
Then, multiply each term by -1. A negative times another negative is a possitive, so -y would become y, and -2x would become 2x, giving you the answer of y=2x.

Step-by-step explanation:
A=2πrh+2πr2
Answer:
1. SA = 216π cm² ≈ 678.24cm²
2. SA = 360π ft²≈ 1130.40ft²
3. SA = 156π yd² ≈ 489.84yd²
4. SA = 576π m² ≈ 1808.64 m²
Step-by-step explanation:
SA of a cylinder = 2πrh + 2πr²
1. r = diameter ÷ 2
r = 12/2 = 6
SA = 2π(6)(12) + 2π(6)²
SA = 144π + 72π
SA = 216π ≈ 678.24
2. r = 19/2 = 9
SA = 2π(9)(11) + 2π(9)²
SA = 198π + 162π
SA = 360π ≈ 1130.40
3. SA = 2π(6)(7) + 2π(6)²
SA = 84π + 72π
SA = 156π ≈ 489.84
4. r = 24/2 = 12
SA = 2π(12)(12) + 2π(12)²
SA = 288π + 288π
SA = 576π ≈ 1808.64

Natalie: 12
Fred: 24
Step-by-step explanation:
x= natalie
y= fred
x+y=36
y+4x=72
Let's start by isolating a variable
x+y=36
x-36= -y
-x+36=y
(we do this step because it's important that the y is a negative)
We can plug this into the second equation
-x+36+4x=72
solve for x
3x=36
x=12
Plug in this x value into any of the two beginning equations
12+y=36
y=24

During a weekend, the manager of a mall gave away gift cards to every 80th person who visited the mall.
On Saturday, 1210 people visited.
On Sunday, 1814 people visited.
How many people received a gift card?
Answers
Answer:
37
Step-by-step explanation:
A manager gives gift cards to every 80th customer. On Saturday, 1210 customers entered, while on Sunday, 1814 customers entered. We are asked to find the number of people who received gift cards.
Consider Saturday:
(1) Probably the most efficient method is to divide 1210 by 80.
(The first gift card was given to the 80th person and 80/80=1. The second to the 160th person and 160/80=2. The third to the 240th person and 240/80=3, etc...)
So 1210 divided by 80 is 15 with a remainder of 10.
15 people received gift cards on Saturday.
(2) We could set up a linear inequality where the unknown x represents the number of people receiving gift cards. Then 80x<1210 and x<15.125 so x=15.
(3) You could just keep adding, perhaps in a table, until you got to the last person:
(# customers, # gift cards): (80,1), (160,2), (240,3)...(1120,14), (1200,15)
The answer will not change, but the manager can either start counting at zero again on Sunday, or continue from the previous day making the first person in on Sunday number 11.
Again we take 1814 divided by 80 to get 22 with a remainder of 54. (With the additional 10 from Saturday we would have remainder 64, but still not enough people to give out another card.)
15 cards given out Sat with 22 cards given out Sun means that there were a total of 15+22=37 people who received gift cards.
Sorry its alot
So 1210/80=15.125 BUT because it’s people it would be 15
Then 1814/80= 22.675 but actually 22
Saturday= 15 and Sunday= 22
If it’s in all then 37
