Answer:
y=(2/3)×-4
Step-by-step explanation:
4y(8/3)×-16 <-----divides everything by 3
To find the equation, find the slope from the two points. The slope formula is (y1-y2)/(x1-x2). Plugging in the two points, you should get 3 as your slope.
As a line, the answer would be y=3x. Therefore, y=3x represents the function described.
Answer:
Ray is x years old.
Ron is x+y years old.
In 2 years, Ron will be two years older than now, so x+y+2 years old.

========================================================
Explanations:
- "4 more than p" means we add 4 onto p. For instance, let's say we replace p with 10. This means "4 more than 10" would be 4+p = 4+10 = 14.
- Not much to say here. We subtract the two items.
- The term "quotient" is the result of dividing two numbers. The slash / symbol means "divide" and it also is used for fractions.
- Skipping.
- Similar to problem 1, but now we subtract since the result is smaller than x. For instance, let's say x = 30. Then 23 less than this is x-23 = 30-23 = 7.
- If n is some number, then twice that is 2n. We add on 2 more to get 2n+2 as the answer.
- Same idea as problem 2. "A number" stands in place of "n".
- "Product" means "result of multiplication". So we multiply 5 and the number to say 5 times n = 5*n = 5n.
- Similar idea to problem 3, but we use "a number" in place of "n".
- We multiply the number of cans (n) with the price per can (0.70) to get 0.70n
Answer:
He needs to complete a distance of 4,030 yards around the rink to make a total skating distance of 3 miles
Step-by-step explanation:
In this question, we are asked to calculate the number of yards needed to complete 3 miles skating around a rink.
We proceed as follows;
First, we can see he has skated 5 times around a rink that has a distance of 250 yards. His total distance covered would be 250 * 5 = 1250 yards
Now he is looking at completing 3 miles, we need to know the number of yards in 3 miles.
Mathematically, 1 mile = 1760 yards
3 miles = 3 * 1760 = 5,280 yards
To know the number of yards he need to skate more, we simply carry out a subtraction;
5,280 yards - 1250 yards = 4,030 yards
