You are running a 10-kilometer race. At 8:00 A.M., you start the race.
At 8:30 A.M., you are 4 kilometers from the finish line. Write a linear
model that gives the distance d (in kilometers) from the starting line in
terms of the time t (in minutes). Let t represent the number of minutes
since 8:00 A.M.
Answer:
It take 20 minutes to run 4 kilometres
Step-by-step explanation:
As we run 6 kilometres in 30 minutes
Equation is 4×30÷6=20
Then each 1kilometre take 5 minutes
Loki wrote 1/6 of a page in 1/12 of a minute. How much time does it take him to write a full page?
−9x−6y=15
9x−10y=145
y=
x=
Answer:
Step-by-step explanation:
Adding the two equations together gives you
9x-10y-9x-6y=145+15
-16y=160
y=-10, using this value in 9x-10y=145 gives you
9x-10(-10)=145
9x+100=145
9x=45
x=5
So y=-10 and x=5
What is y, when x = 7. y = 3x + 10
PLEAS HELP I NEED IT RN
Answer: y = 31
Step-by-step explanation:
y = 3x + 10
y = 3(7) + 10 Plug in the 7 for x, because it shows x = 7 in the question.
y = 21 + 10
y = 31

Find the solution set of the inequality
8x−8≤−72.
Answer:
x≤-8
Step-by-step explanation:
When solving 8x-8≤-72, first add 8 to both sides of the inequality.
This leaves you with 8x≤-64.
Divide both sides by 8: 8x/8 and -64/8
This leaves you with x≤-8 as your solution.
Robbie uses 1 1/2 cups of brown sugar for every 2 loaves of banana bread he bakes. Robbie has 5 boxes of brown sugar. Each box contains 2 1/2 cups of brown sugar. Assuming he has plenty of the other ingredients, what is the maximum number of whole loaves of banana bread Robbie can bake?
Answer:
16 loaves of banana breadStep-by-step explanation:
1 1/2 cups of sugar required for 2 loaves of bread
Amount of sugar required for 1 loaf of banana bread:
1/2*1 1/2 = 1/2*3/2 = 3/4 cupsTotal amount of brown sugar:
5* 2 1/2 = 5*5/2 = 25/2 cupsPossible maximum number of loaves of bread:
25/2 ÷ 3/4 = 25/2 * 4/3 = 50/3 ≈ 16 (taking whole number)how do you turn fractions into decimals?
Answer:
You would need to divide the numerator by the denominator in order to convert a fraction into a decimal
Step-by-step explanation:
Answer:
You divide the numerator by the denominator.
Step-by-step explanation:
For example, you covert the fraction [tex]\frac{1}{2}[/tex] into a decimal.
You just do: 1÷2=0.5, and there you have it, the decimal!

Annie wants to eat an entire donut. However, since she only two-years-old, the mother says she can
only have a third of the donut. If the diameter of the donut is 4 inches, how long is the outside edge of
the piece that Annie gets to eat? Round your answer to the nearest hundredth of an inch.
Answer:
4.19 inches
Step-by-step explanation:
Your goal is to find the circumference of the donut and then divide that by 3 to get 1/3 of the outer edge of the donut.
Circumference is 2[tex]\pi[/tex]r
The diameter (double the radius) is 4, so radius (r) is 2
2 * pi * 2 = 4 pi = 12.57 (round to hundredth)
12.57/3 = 4.19
keep in mind that dividing by 3 is the same as multiplying by 1/3

Answer:
The son is 4years old
Step-by-step explanation:
Let the son's age=x
the father's age=8x
IN 10YEARS,
Son's age=x+10
father's age=8x+10
Equate them
8x+10=3(x+10)
8x+10=3x+30
5x=20
x=4
