Math Question for An assignment
Answer: y = 5/2x + 4
Step-by-step explanation:
y = 5/2x + c
1) Substitute
-6 = 5/2(-4) + c
-6 = -10 + c
-6 + 10 = c
4 = c
y = 5/2x + 4 or
y = 2.5x + 4

Step-by-step explanation:
Suppose you have a 100 AED of coupons at Dubai Expo 2020. You spend 30 AED per game. Write an equation that models the total amount of money y you spent if you play x games.
The total amount of money y you spent if you play x games is expressed as y = 1/30x
Given the following
Total amount of AED of coupons at Dubai Expo 2020 = 100 AED
If you spend 30 AED per game, this can be expressed as:
30 AED = 1 game
100 AED = x game
Cross multiply
30 x = 100 * 1
30x = 100
x = 100/30
x = 10/3 games
This shows that 100 AED of coupons is used for 10/3 games
100 AED = 10/3 games
y AED = x games
Cross multiply
100 x = 10/3 y
100xy = 10/3
10 xy = 1/3
30xy = 1
y = 1/30x
Hence the total amount of money y you spent if you play x games is expressed as y = 1/30x

In the given question -
The first reason is given in the question itself.
The second reason is given by congruency.
The third reason is again given in the question.
The fourth reason is also given.
Finally, in the fifth reason, we can conclude that it is substitution because by the second reason m of ∠A is congruent to m of ∠B. So, if we remember the substitution we can assign the value of m∠A to the value of m∠B because both are congruent by the second reason.
Therefore, the reason that best supports statement 5 in the given proof is Substitution.

what is the first digit in the quotient of 1,898 divided by 9
9514 1404 393
Answer:
0
Step-by-step explanation:
The first digit of the quotient is 0. This is because the first digit of the dividend (1) is less than the divisor (9).
See the attached image for the complete long division.
__
The first non-zero quotient digit is 2 = 18/9.
Part A: The sun produces 3.9 ⋅ 1033 ergs of radiant energy per second. How many ergs of radiant energy does the sun produce in 3.25 ⋅ 103 seconds? (5 points)
Part B: Which is the more reasonable measurement of the distance between the tracks on a railroad:
1.435 ⋅ 10−3 mm or 1.435 ⋅ 103 mm? Justify your answer. (5 points)
9514 1404 393
Answer:
A) 1.3×10^37 ergs
B) 1.435×10^3 mm
Step-by-step explanation:
A) The quantity is found by multiplying the rate by the time:
(3.9×10^33 ergs/s)×(3.25×10^3 s) = 1.2675×10^37 ergs ≈ 1.3×10^37 ergs
The least-precise contributor to the calculation has 2 significant digits, so we need to round the result to 2 significant digits.
__
B) A fine human hair is more than 40×10^-3 mm in diameter, so the distance 1.435×10^-3 mm is completely unreasonable for railroad track spacing. The space between rails is closer to 1.4 meters. So 1.435×10^3 mm is a better measurement.

(I'LL GIVE BRAINLIEST) Carson wanted to buy a cowboy hat that cost $49.95 (with tax) at a souvenir shop. He knew he had $18 at home already, and he could earn $10 per lawn by mowing lawns for his neighbors. He came up with the following expression to figure out how many lawns he would need to mow in order to purchase the hat: M = 10w + 18 with "w" being the number of lawns he would need to mow and "M" being the total amount of money he has.
Carson then determined he would need to mow 3 lawns by completing the follow steps:
50 = 10w + 18
32 = 10w
3.2 = w
Identify Carson's error. Explain the steps to correctly solve for how many lawns Carson needs to mow. Be sure to clearly state the correct answer.
Answer:
so Carson's problem was at the end, since the neighbors are paying 10$ PER DAY, and 3 days work would only earn him 30$ meaning at the end he would be a dollar short, technically, he needs to work exactly 3.2 days, or...
let's say he works 4 hrs a day
1 Day = 4Hr
3.2 Days = X
X = 3.2 × 4
= 12.8 Hrs
so Carson needs to work 3 days and an extra 48 Minutes
