2. Solve for y
i posted the same question but they didn’t tell me how they got it so could someone show me how they got the answer pleaseee
Answer:
y= -6
Step-by-step explanation:
-4y - 20 + 19 = -y + 17 *add y on the right to get rid of -y
+y +y then add it to -4y
-3y - 20 + 19 = 17 *add 20 to the left to get rid of -20
+20 +20 then add it to 17
-3y + 19 = 37 *subtract 19 from the left to get rid of 19
-19 -19 then subtrcat 19 from 37 as well
-3y = 18 *now we want to divide both sides by -3 to
-3 -3 get y by it's self
y = -6 *no we're left with y = -6 :D

The tape diagram models the lengths of two snowboarding trails. The expert trail is 750 meters longer than the beginner trail. How long is each trail? ( Beginner trail: 1 length. Expert trail: 4 lengths)
Answer:
In a tape diagram, each of the lengths represents a fixed quantity of something.
Let's suppose that each one of these lengths represents a distance d.
We also know that the expert trail is 750 meters longer than the beginner one.
And in the tape diagram, the expert trail has 3 more lengths than the beginner trail, then we must have that the difference in distance must be equivalent with the difference in lengths.
750m = 3*d
d = 750m/3 = 250m
Then each length in the tape diagram represents 250m
With this we can find the length of each trail.
The beginner trail has 1 length, then it is 1*250m = 250 meters long.
The expert trail has 4 lengths, then it is 4*250m = 1000 meters long.

A wheel has a radius of 13”; calculate the circumference.
Answer:
81.71"
Step-by-step explanation:
Circumference = 2*pi*radius
pi = 22/7
radius = 13
Circumference = 2*22/7*13 = 44*13 / 7 = 572/7 = 81.71"

The plans for a new street show lamp post that are 2.5 inches apart. If the plans use a scale of 0.5 inch = 9 yards, find the actual distance between the lamp posts.
Answer: 45 yards
Step-by-step explanation:
From the question, we are given the information that the plans for a new street show lamp post that are 2.5 inches apart and that the plans use a scale of 0.5 inch = 9 yards,
Since a scale of 0.5 inch = 9 yards is used, the actual distance between the lamp posts will be:
= (2.5inches / 0.5 inches) × 9 yards
= 5 × 9 yards
= 45 yards
If -3d + 5 = -3 , then 3d - 9 =
Answer:
-3d+5=-3 is d=8/3
3d-9 is (d-3)

In ΔABC, m ∠ A = ( 3 x + 1 ) ∘ m∠A=(3x+1) ∘ , m ∠ B = ( x + 14 ) ∘ m∠B=(x+14) ∘ , and m ∠ C = ( 4 x + 5 ) ∘ m∠C=(4x+5) ∘ . What is the value of x ? x?
Answer:
x = 20
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 given angles and equate to 180
3x + 1 + x + 14 + 4x + 5 = 180, that is
8x + 20 = 180 ( subtract 20 from both sides )
8x = 160 ( divide both sides by 8 )
x = 20

Ivian scores 58 out of 80 marks in a maths test what is his score as a percentage
Measure of angle A : 3x
Answer: 11 degrees
Step-by-step explanation:
Each correct answer is worth 134 points, and each incorrect answer is worth −14 points. If he gets 58 questions correct and 22 questions incorrect, does Nevan win? How many points does he score?
Answer:
i. Yes, Nevan won.
ii. Nevan scored 7464 points.
Step-by-step explanation:
Given: each correct answer = 134 points
each incorrect answer = -14 points
Since he got 58 questions correctly, then;
His number of points = 134 x 58
= 7772 points
Also, he got 22 incorrect questions, then;
His number of points = -14 x 22
= -308
Nevan's total points = 7772 + (-308)
= 7772 - 308
= 7464
Nevan scored 7464 points.
Nevan won, and also had a total of 7464 points.
Answer:
yes nevan won
Step-by-step explanation:

A nightclub has approximated the demand for their Thursday night drink special by p^2+200q^2=177, where p is the price (in dollars) and q is the quantity demanded (in thousands). Find and interpret when the price is $ 7 and the demand is 800 drinks.
Answer:
Step-by-step explanation:
Given the approximate demand function of night drink expressed as;
p^2+200q^2=177,
p is the price (in dollars) and;
q is the quantity demanded (in thousands).
Given
p = $7
q = 800
Required
dq/dp
Differentiating the function implicitly with respect to p shown;
2p + 400d dq/dp = 0
400q dq/dp = -2p
200qdq/dp = -p
dq/dp = -p/100q
substitute p and q into the resulting equation;
dq/dp = -7/100(800)
dq/dp = -7/80000
dq/dp = -0.0000875
This means that the rate of change of quantity demanded with respect to the price is -0.0000875

The length of Joe's arm is 28 inches. The length of his lower arm is 21 inches. What percent of Joe's arm is his lower arm?
Answer:
75%
Step-by-step explanation:
You take the length of the lower arm, 21, and divide it by the total length, 28. Your equation should be 21/28 = 3/4 =.75. 0.75 is equal to 75%
Answer:
75%
Step-by-step explanation:
You take the length of the lower arm, 21, and divide it by the total length, 28. Your equation should be 21/28 = 3/4 =.75. 0.75 is equal to 75%
