In the equation, y = 8.5x the variable y represents time and x represents the distance in miles.
What is a linear equation?The linear equation is defined as the equation having a degree of one or the power of the variable will be one. It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
Given that John ran 3 miles in 25.5 min the equation y = 8.5x. The equation is satisfying the answers. The solution will be calculated as follows:-
y = 8.5x
Here, the y variable is the total time and x is the distance in miles.
y = 8.5x
For 3 miles the time will be calculated as follows:-
y = 8.5 x 3
y = 25.5 minutes
Therefore, in the equation, y = 8.5x the variable y represents time and x represents the distance in miles.

Answer:
C y=2x-6
Step-by-step explanation:
the diffrence in each one is two by using two as slope you get -6 as y intercept.
Answer:
y = 2x - 6 (Third option)
Step-by-step explanation:
(-6, -18), (-1, -8)
m = (-8 - (-18)) / (-1 - (-6))
m = (-8 + 18) / (-1 + 6)
m = 10 / 5
m = 2
-8 = 2(-1) + b
-8 = -2 + b
b = -6
y = 2x - 6

work out the area of a semi circle take pi to be 3.142 and five your answer to two decimal places
Answer:
what are the measurements of the semi circle
Step-by-step explanation:
5(y + 2) = 6(y - 1)
Show work
Please and thank you
Answer:
5 ( y + 2) = 6 ( y - 1)
- distribute the number outside into the parenthesis by multiplying it with each value
5y + 10 = 6y - 6
- subtract like terms, in this case 5y and 6y
-y + 10 = -6
- isolate the variable ( y) by getting rid of 10 by subtracting it to both sides
-y = -16
-1y = -16
- isolate variable (y) by getting rid of the -1 next to it by dividing it to both sides
y = -16 / -1
y = 16
Last year's computer models were priced at $1,850. They are now discounted 20%. What is the new retail price to the nearest dollar of that computer? $370 $1,480 $1,510 $1,830
Answer:
$1480Step-by-step explanation:
Step one:
Given that the price last year was $1850
and now the discount is 20%
we first need to solve for 20% of $1850
=20/100*$1850
=0.2*$1850
=$370
This means that the price was reduced by $370
so the new retail price is calculated as
=$1850-$370
=$1480

Markups The depth of water in a pond increases by 3% after a heavy rain. If the average depth of the water was 8.3 feet, what is the new depth?
Answer: 8.55 feet
Step-by-step explanation:
We should equal the average depth to 1, so if it raises 3%, it raises 0.03. Simply add the original (1) plus what it rose (0.03) and multiply the original by that, so 8.3 × 1.03 = new depth. The result is 8.549 feets.

Step-by-step explanation:
Point S is on line segment \overline{RT} RT . Given RT=4x,RT=4x, ST=5x-10,ST=5x−10, and RS=6,RS=6, determine the numerical length of \overline{ST}. ST .
Answer:
[tex]ST = 10[/tex]
Step-by-step explanation:
Given
[tex]RT =4x[/tex]
[tex]ST = 5x - 10[/tex]
[tex]RS = 6[/tex]
Required
Determine ST
Since S is on RT, we have that:
[tex]RT = RS + ST[/tex]
[tex]4x = 5x - 10 + 6[/tex]
[tex]4x = 5x - 4[/tex]
[tex]4x - 5x= - 4[/tex]
[tex]-x= - 4[/tex]
[tex]x= 4[/tex]
Substitute 4 for x in [tex]ST = 5x - 10[/tex]
[tex]ST = 5 * 4 - 10[/tex]
[tex]ST = 20 - 10[/tex]
[tex]ST = 10[/tex]

A yardstick casts a shadow of 24 in. At the same time a telephone pole casts a shadow of 20 ft 8 in. What is the height of the telephone pole, to the nearest inch? (1 yd = 36 in., and 1 ft = 12 in.)
Answer:
372 inches
Step-by-step explanation:
(1 yd = 36 in., and 1 ft = 12 in.)
1 yard stick = 24 in
This means , height of 36 inches casts a shadow of 24 Inches
At the same time a telephone pole casts a shadow of 20 ft 8 in
1 ft = 12 in
Hence,
Convey 20ft to inches
1 ft = 12 in
20 ft = 20 × 12 inches
= 240 inches
Total shadow of the telephone pole = 240in + 8 in = 248 = 248 inches
Hence,
Height/Length of shadow = Height/Length of shadow
36/24= x /248
Cross Multiply
24 × x = 36× 248
x = 36 × 248/24
x = 372 inches
The height of the telephone pole, to the nearest inch is 372 inches

On Wednesday Mr. Miles walked in right at 9/10 of the trail then he walked one eights of the trail back and you stop to rest what fraction of the course with Mr. Miles from the beginning of the trail when he stopped
Answer:
31/40
Step-by-step explanation:
Given that:
Fraction of the trail walked intulally = 9/10
Fraction of the trail walked back = 1/8 before stopping to rest
His current distance from the beginning :
Distance walked initially - distance walked back
9/10 - 1/8
The L. C. M of 10 and 8 = 80
Hence,
9/10 - 1/8
= (72 - 10) / 80
= 62 / 80
= 31 / 40
Hence, his rest point or position is 31/40 from the beginning of the trail

Answer:
Hope it help, please give me BRAINLEST!
Step-by-step explanation:
2y + 5= |3y| + 3 = 3
x - 3= 2
[tex]\sqrt{x} + 2 = 2[/tex]
5x - 17= -3x = 2
3^(x )= 4

The calorie count of a serving of food can be computed based on its composition of carbohydrate, fat, and protein. The calorie count for a serving of food can be computed using the formula C=4h+9f+4p, where his the
of grams of carbohydrate contained in the serving, is the number of grams of fat contained in the serving, and is the number of grams of protein contained in the serving
A serving of a certain type of but contains 12 grams of fat, 6 grams of carbohydrate, and 5 grams of protein. How many calones are in this serving of ruts?
There are calories [___] in this serving of nuts
Answer:
152 calories
Step-by-step explanation:
The calories count, composition of carbohydrates, fat and protein are related by;
C = 4h + 9f + 4p
where C, h, f, and p have there given meaning.
Given that the serving of a type of nut contains; f = 12 grams, h = 6 grams and p = 5 grams, then;
C = 4(6) + 9(12) + 4(5)
= 24 + 108 + 20
= 152
C = 152 calories
Therefore, there are 152 calories in the serving of the certain type of nut.

Put the following equation of a line into slope-intercept form, simplifying all fractions. 3x+4y=-4
Answer:
Don't come at me if I'm wrong, but I think it's y=-3/4x-1 1/3
Step-by-step explanation:
1) you have to subtract 3x from both sides (this makes it 4y=-3x-4)
2) you then divide by 4 on both sides (it will become y=-3/4=4/3)
3) then you simplify the fractions (it becomes y=-3/4x-1 1/3)

What is a right-angle triangle?It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function. The Pythagoras is the sum of the square of two sides is equal to the square of the longest side.
The right-angle triangle is shown in a diagram. Then by the Pythagoras theorem, we have
P² = H² - B²
P² = 25² - 7²
P² = 625 - 49
P² = 576
