Given:
The distance y (in meters) that runner A travels on a track in x minutes is represented by the equation
[tex]y=130x[/tex]
To find:
How many meters per minute is runner A traveling.
Solution:
We have,
[tex]y=130x[/tex] ...(i)
Where, y is the distance in meters and traveling x minutes.
We need to find the slope of the above equation to find the number of meters traveling by the runner per minute.
The slope intercept form of a line is:
[tex]y=mx+b[/tex] ...(ii)
Where, m is the slope and b is the y-intercept.
On comparing (i) and (ii), we get
[tex]m=130[/tex]
Therefore, the runner is traveling 130 meters per minute.
Janie has 2 3/4 yards or yellow ribbon. She uses 1/2 of the ribbon to decorate bookmarks for her cousin. How many yards of ribbon did Janie use for her bookmarks
Answer:
1 3/8 yards
Step-by-step explanation:
Janie has 2 3/4 yards of yellow ribbon. She uses 1/2 of the ribbon to decorate bookmarks for her cousin. How many yards of ribbon did Janie use for her bookmarks
The above question is calculated as:
2 3/4 yards × 1/2 of ribbon
= 2 3/4 × 1/2
= 11/4 × 1/2
= 11/8
= 1 3/8 yards
Therefore, Janie used 1 3/8 yards of ribbon for her bookmarks

She earns \$20$20dollar sign, 20 per hour as a carpenter and \$25$25dollar sign, 25 per hour as a blacksmith. Last week, Giselle worked both jobs for a total of 303030 hours, and earned a total of \$690$690dollar sign, 690.
Answer:
Carpentry = 12 hours Blacksmithing = 18 hoursStep-by-step explanation:
Question wants to know the number of hours se worked at each.
This is a simultaneous equation problem.
Assume the carpenter job is x and the blacksmith is y.
x + y = 30
20x + 25y = 690
Substitution:
x + y = 30
y = 30 - x
20x + 25y = 690
20x + 25(30 - x) = 690
20x + 750 - 25x = 690
-5x = 690 - 750
-5x = -60
x = -60/-5
= 12 hours for carpentry
y = 30 - x
= 30 - 12
= 18 hours for blacksmithing

Use the Distributive Property to simplify the expression
4(c - 2)
Answer:
4c - 8
Step-by-step explanation:
Like they said, use Distributive Property
4 x c = 4c
(Keep the subtraction sign because your just multiplying both numbers by 4)
4 x 2 = 8
therefore it would be,
4c - 8
Answer:
4c-8
Step-by-step explanation:
The distributive property would make it so that 4 is multiplied to everything within the parentheses.
4(c - 2)
4 x c = 4c
4 x -2 = -8
Therefore, your answer is 4c-8

, GIVING FIRST ANSWER BRAINLIEST! How many milliliters are in 1 liter?
Answer: 1000 mL
Step-by-step explanation:
Answer: 1000 Milliliters
Step-by-step explanation:
Convert 1 Liters to Milliliters
To calculate 1 Liter to the corresponding value in Milliliters, multiply the quantity in Liters by 1000 (conversion factor). In this case, we should multiply 1 Liters by 1000 to get the equivalent result in Milliliters:
1 Liters x 1000 = 1000 Milliliters
1 Liter is equivalent to 1000 Milliliters.
Quick conversion chart of milliliters to liters
1 milliliters to liters = 0.001 liters
10 milliliters to liters = 0.01 liters
50 milliliters to liters = 0.05 liters
100 milliliters to liters = 0.1 liters
200 milliliters to liters = 0.2 liters
500 milliliters to liters = 0.5 liters
1000 milliliters to liters = 1 liters
