Answer:
17minutesStep-by-step explanation:
Given the equation of the time t = 8.5d took by aa runner to ru n. If the runner ran 2 miles, to calculate the time take by the runner to run two miles, we will substitute d = 2 into equation and calculate t as shown;
t = 8.5d
t = 8.5(2)
t = 17.0 minutes
Hence it will take the runner 17minutes to run 2 miles.
Runner #2's equation is an illustration of proportional equations
It will take runner #2 17 minutes to run 2 miles
Runner #2's equation is given as:
[tex]\mathbf{t = 8.5d}[/tex]
When runner #2 runs two miles, it means that:
d = 2
Substitute 2 for d in the given expression.
So, we have:
[tex]\mathbf{t = 8.5 \times 2}[/tex]
Multiply
[tex]\mathbf{t = 17}[/tex]
Hence, it will take runner #2 17 minutes to run 2 miles

What is the value of q in the equation 5q − 10 = 75? (4 points)
A.17
B.60
C.65
D.85
Answer:
Q=17
Step-by-step explanation:
5q − 10 = 75
Add ten to both sides=5q=85
Divide both sides by 5=q=17
Answer:
A. 17
Step-by-step explanation:
Solve for q:
[tex] \longrightarrow[/tex] 5q - 10 = 75
Add 10 to both sides:
[tex] \longrightarrow[/tex] 5q + (10 - 10) = 10 + 75
10 - 10 = 0:
[tex] \longrightarrow[/tex] 5q = 75 + 10
75 + 10 = 85:
[tex] \longrightarrow[/tex] 5q = 85
Divide both sides of 5q = 85 by 5:
[tex] \longrightarrow[/tex] [tex] \sf \dfrac{5q}{5} = \dfrac{85}{5} [/tex]
[tex] \sf \dfrac{5}{5} [/tex] = 1:
[tex] \longrightarrow[/tex] q = [tex] \sf \dfrac{85}{5} [/tex]
[tex] \sf \dfrac{85}{5} [/tex] = 17:
[tex] \longrightarrow[/tex] q = 17

Find the Slope between two points: (-1,9) and (2, 3)
Answer:
Slope = -2
Step-by-step explanation:
x1 y1 x2 y2
(-1 , 9) (2 , 3)
Slope = y2 - y1
x2 - x1
3 - 9 = -6
2 -(-1) = 3
= -2
The slope between the two points is -2.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
The slope is given as,
m = (d - b) / (c - a)
Where (a, b) and (c, d) are the two points.
Now,
(-1, 9) = (a, b) and (2, 3) = (c, d)
m = (3 - 9) / (2 + 1)
m = -6 / 3
m = -2
Thus,
The slope is -2.

Answer:
B. 66
Step-by-step explanation:
idk how to explain it without repeating what it says in the answer
Answer:
The answer is:
B) 66 degrees
Step-by-step explanation:
Since the triangle is an isosceles triangle, angle C is the same as angle B.
57 + 57 = 114
Since you know two of the three angles, and you know that a triangle's angles must equal 180 degrees...
180 - 114 = 66
Angle A must equal 66 degrees for the triangle to equal 180 degrees.

If the given equations are y=3x+14 and y= -4x. The value of x and y for the equation will be -2 and 8 respectively.
What is an equation?Equations are statements that affirm the equivalence of two expressions that are joined by the equals symbol "=". An equal sign ("=") links two expressions together to form an equation. The two expressions on each side of the equals sign are referred to as the "left-hand side" and "right-hand side" of the equation.
It is given that the equations are,
y=3x+14 ----------(1)
y= -4x -------------(2)
In order to solve "by substitution," you must first solve one of the equations for one of the variables (you choose which one), plug that solution back into the other equation, "substituting" for the selected variable and then solve for the other.
Substitute the value of y from equation 2 in equation 1 as
y=3x+14
-4x=3x+14
Rearrange the equation in order to find the value of x as
-4x-3x=14
-7x=14
x= -14/7
x= -2
Put the value of x in equation 2 as
y= -4x
y= -4(-2)
y=8
Thus, if the given equations are y=3x+14 and y= -4x. The value of x and y for the equation will be -2 and 8 respectively.

Thomas rented a bus so he and his friends could go to a concert. He had to pay a flat fee of $40 for the bus plus an additional $0.70 per mile. If he paid a total of $104.40, how many miles in total was the trip?
Answer:
so if Thomas payed $40 for the bus we have to find what he payed not including the $40 bus fee.
so we have to subtract 40 from the total price of $104.40.
the equation is 104.40-40=?
104.40-40=$64.40 payed outside the bus fee.
now we have to figure out how many times .70 fits into 64.40
the equation would be 64.40/.70 which means we are dividing 64.40 by .70
so 64.40/.70=92
Thomas and his friends traveled a total of 92 miles to go to the concert.
