Answer:
K - Constant of proportionality
Y/X = K
Step-by-step explanation:
Can’t see the graph but the first point can be calculated. If your first point is (100,78) that’s (x,y), your k = 78/100, $78 US dollars and 100 euros, thus the unit rate is 78/100 = 0.78/1 which means 0.78 dollars equals 1 euro.

Answer:
I believe it would be A: 60°.
Step-by-step explanation:
I suck at explaining stuff but since R is 60°, and theres 120° outside of the triangle, that implies T = 60°. Triangles equal 180° so
60° + 60° + S = 180°
S = 60°
Hope this helps
Answer:
The answer of the question is 60° which is option(A).
here,
let one be suppose angle a°
a°+ 120° = 180° {being straight angle}or, a° = 180° - 120°
or, a° = 60°
a° = 60°
Now,
Let angle S be s°
s°+60°+60° = 180°{ the sum of angle of triangle is 180°}
or, s° = 180° - 120°
or, s° = 60°
therefore, angle S is 60°
The department store sells logo t-shirts at an original price of $12.50. Every month that a t-shirt doesn’t sell, the store reduces the price by 25%. Brianna calculated the price after two reductions:
12 dollars and 50 cents minus (12 dollars and 50 cents) (0.25) minus (12 dollars and 50 cents) (0.25) = 6 dollars and 25 cents
What is Brianna’s error?
Answer:
Brianna subtracted $12.50, even though you are not supposed to do that to find the price. You have to subtract $6.50, not $12.50.
The final answer is $7.04 because you subtract two initial prices.
Hope this helps you!
Answer:
The sample answer is :Brianna took both 25% discounts off the original amount. The second discount should have been calculated on the first reduced price of $9.38. The final sale price should have been $7.03.

20. Line L has a y-intercept of 2 and contains the points (a, a) and (2a, 12). If a is a positive constant, what is the slope of line L?
Answer:
(12 - a)/aStep-by-step explanation:
Given
Line L withy-intercept = 3Points (a, a) and (2a, 12)The slope is
m = (y2 - y1)/(x2 - x1) = (12 - a)/(2a - a) = (12 - a)/aAndy and Christopher are measuring a liquid solution using graduated cylinders. Andy uses 3.5liters of the liquid solution, and Christopher uses 2,580milliliters of the liquid solution. What is the ratio of Christopher's measurements to Andy's measurements in milliliters?
Answer:
129:175
Step-by-step explanation:
Andy and Christopher are measuring a liquid solution using a graduated cylinder
Andy uses 3.5 liters of the liquid solution
3.5 liters to mililiters
= 3.5 ×1000
= 3500 mililiters
Christopher uses 2580 mililiters
Therefore the ratio of Christopher's measurement to Andy's measurement can be calculated as follows
= 2580/3500
= 129 : 175
Hence the ratio of Christopher's measurement to Andy's measurement is 129:175

Trinity sold candles for $7 each after she paid a $10 setup fee. The equation f(x)=7x-10 shows the profit Trinity will make from selling candles where x is the number of candles and f(x) is the profit she will make. If Trinity has 30 candles to sell, find the domain and range of the function.
Domain: 200
Range: 200
∠1 and ∠2 are complementary angles. Given m∠1=83°, find m∠2.
Reasoning: Complementary angles always add to 90 degrees.
If angle 2 was x, then x+83 = 90 solves to x = 7
The measure of m∠2 is 7° due to the pair of angles being complementary.
What are complementary angles?The complementary angles are defined as when pairing of angles addition to 90° then they are called complementary angles. There are two types of supplementary angles.
Adjacent angles: Adjacent angles are the type of supplementary angles. Adjacent angles have a common side and vertex, for example, a corner point. Their points do not overlap in any way. In other terms, adjacent angles are pairs of two angles next to each other.
We have been given that the pair of angles as
m∠1 = 83° and m∠2 = x
Here, the pairing of angles sums up to 90° then they are called complementary angles.
So x + 83 = 90°
⇒ x = 90° - 83°
⇒ x = 7°
Therefore, the value of m∠2 is 7°.

Marta purchased screws and nails at a hardware store. She paid $0.10 for each screw and $0.05 for each nail. She purchased 15 screws but did not count the number of nails she purchased. She paid a total of $5.20 for the screws and nails. How many nails did Marta purchase?
Answer:
104
Step-by-step explanation:
Based on the total amount spent, we can infer that the number of nails Marta purchased was 74 nails.
Marta purchased 15 screws which cost $0.10 each. The cost is therefore:
= 15 x 0.10
= $1.50
The amount spent on nails is:
= 5.20 - 1.50
= $3.70
If each nail cost $0.05, the total nails bought is:
= 3.70 / 0.05
= 74 nails
In conclusion, 74 nails were purchased.

Answer:
first problem) he messed up at 4(1 + 5n), only multiplying the 1 by 4, instead of both the 1 and 5n,
work-
-8n + 4(1 + 5n) = -6n - 14
-8n + 4 + 20n = -6n -14
12n + 4 = -6n - 14
18n +4 = -14
18n = -18
n= -1
second problem) he messed up towards the end, where he put 3x = 3x, then x=0. in this case, x would equal x, so the answer is "infinitely many solutions"
all the other work is correct in that problem
third problem) on the right side of the equation, ( 4x+10+3x-6), when they were adding the like numbers, instead of subtracting 6 from 10, they added 6, giving them 16 instead of 4
correct work-
2x - 8 + 3x +2 = 4x +10 + 3x -6
5x - 6 = 7x + 4
-5x -5x
-6 = 2x +4
-4 -4
-10 = 2x
-5 = x

Please I need help and the calculation of which contract is better.
The monthly contract I am considering costs $30 per month with 75 minutes of free calls and 100 free text messages. Additional calls cost 10¢ per minute and additional text messages 10¢ each. An alternative is ‘Pay as you go’ which has no monthly charge but all calls cost 30¢ per minute and texts cost 10¢ each. I typically make 100 minutes of calls and 60 text messages each month. Which would be the better contract for me and by how much?
Answer:
You should go with the 1st, because it's cheaper.
Step-by-step explanation:
1st plan:
30$ which include 75 mins of free calls and 100 free text messages
25 more mins * 10¢ /min(0.1$/min) = 2.5$
You will pay 32.5$
2nd plan:
(calls)100*0.3$=30$
(text messages)100 * 0.1$=10$
30+10 = 40$

Thank you for the help
Answer:
x = -8
Step-by-step explanation:
3(x+1)+11=-2(x+13)
3x+3+11=-2x-26
3x+14=-2x-26
5x=-40
x=-8
Answer:
x = -8
Step-by-step explanation:
Step 1: Write equation
3(x + 1) + 11 = -2(x + 13)
Step 2: Solve for x
Distribute: 3x + 3 + 11 = -2x - 26Combine like terms: 3x + 14 = -2x - 26Add 2x to both sides: 5x + 14 = -26Subtract 14 on both sides: 5x = -40Divide both sides by 5: x = -8Step 3: Check
Plug in x to verify it's a solution.
3(-8 + 1) + 11 = -2(-8 + 13)
3(-7) + 11 = -2(5)
-21 + 11 = -10
-10 = -10
