Rosa loves to run. She set a goal to run greater than 490 miles this year. To date, she has run 145 miles. If she begins to run 15 miles per week, how long will it take Rosa to reach her goal?
Write an inequality, using x as the variable, that represents this situation.
Answer:
Step-by-step explanation:
145+15x>490. subtract 145 from both sides
15x>345, divide both sides by 15
x>23
So she will need to run for more than 23 weeks to reach her goal.

1) A straight line is perpendicular to y=2x+5 and passes through (0,3).
What is the equation of the line??
2) A straight line is perpendicular to y=0.5x+3 and passes through (3,5).
What is the equation of the line??
3) A straight line is perpendicular to y=4-5x and passes through (20,5).
What is the equation of the line??
Answer:
See explanations below
Step-by-step explanation:
We are going to be using the point slope form of equation of a line for all the question, This is expressed as;
y-y0 = m(x-x0)
1) For a straight line is perpendicular to y=2x+5 and passes through (0,3).
Slope of the line m = 2
Slope of the line perpendicular M = -1/m
M = -1/2
Substituting M = -1/2 and the point (0,3) into the equation
y-y0 = m(x-x0)
y - 3 = -1/2(x-0)
y-3 = -x/2
2(y-3) = -x
2y-6 = -x
-x-2y = -6
x+2y = 6
The required equation is x+2y = 6
2) For a straight line is perpendicular to y=0.5x+3 and passes through (3,5).
Slope of the line m = 0.5
Slope of the line perpendicular M = -1/m
M = -1/0.5
M = -2
Substituting M = -2 and the point (3,5) into the equation
y-y0 = m(x-x0)
y - 5 = -2(x-3)
y-5 = -2x+6
y+2x = 6 + 5
y+2x = 11
The required equation is y+2x = 11
3) A straight line is perpendicular to y=4-5x and passes through (20,5).
Slope of the line m = -5
Slope of the line perpendicular M = -1/m
M = -1/-5
M = 1/5
Substituting M = -2 and the point (20,5) into the equation
y-y0 = m(x-x0)
y - 5 = 1/5(x-20)
5(y-5) = x-20
5y-25 = x-20
5y-x = -20+25
5y-x = 5
The required equation is 5y-x = 5

6) Parking lot A charges $19.00 to enter the parking lot plus $1.50 per hour
for parking. Parking lot B charges $14.00 to enter plus $2.75 per hour. After
how many hours is the cost the same at both both parking lots?
Your answer
Answer:
4 Hours.
Step-by-step explanation:
You would set this up as an equality where x represent hours
19.00 + 1.50x = 14+2.75x
You then get the x on one side by subtracting 14 from both sides and 1.50x from both sides.
5 = 1.25x
Divide both sides by 1.25 to x by itself.
4 = x

PLEASE HELP!! im sorry if its hard to read the text
Answer:
9. 2*50=100
3*50=150
3.5*50=175
200 divided by 50 = 4
8*50=400
10. 50
Step-by-step explanation:
First you find the amount for 1 soda syrup
2 divided by 100 is 50
You can also prove this because 250 divided by 5 is also 50
So one unit or soda syrup is 50
Now you can just multiply each unit or soda syrup by 50
2*50=100
3*50=150
3.5*50=175
200 divided by 50 = 4 (for this one you divide 200 by 50)
8*50=400

find the measure of angle 8
Answer: 18
Step-by-step explanation:
First we need to solve for x to find the measure of the adjacent angle.
-6x+64 = 8x + 162
subtract 162 to leave x by itself
-6x- 98 = 8x
add 6x to both sides
-98 = 14x
now divide by 14
x = -7
Now solve one of the given equations to find the measure of the adjacent angle.
8(-7)+162
-56 + 162 = 106
Meaning the measure of angle 8 is 18
because they'll add up to 180(The measure of the line)
Answer:
measure of angle 8 is 16 6/7
Step-by-step explanation:
-6x+64=8x+62 because there is a transversal.
2=14x
x=2/14
so, now you have to find 8x+162. 163 1/7 degrees. (Plug in variables)
measure of the angle we just found + measure of angle 8 is 180 degrees.
(straight line definition) so 180-163 1/7= 16 6/7
measure of angle 8 is 16 6/7

Answer:
multiplication
Step-by-step explanation:
product is the answer to a multiplication equation, so 162 = j * 9
Answer:
162 = 9j
Step-by-step explanation:
The "product of" means multiplication. So 162 is the answer to Janelle's age times 9.
162 = 9j or 162 = 9 × j

rewrite using a single positive exponent
Answer:
9³
Step-by-step explanation:
We need to find the value of [tex]\dfrac{9^5}{9^2}[/tex].
We know that,
[tex]\dfrac{x^a}{x^b}=x^{a-b}[/tex]
Here, a = 5 and b = 2.
So,
[tex]\dfrac{9^5}{9^2}=9^{5-2}\\\\=9^3[/tex]
So, the answer to the given expression is 9³.
