GUYS HELP PLS WHAT IS AN EQUATION FOR THIS PROBLEM

Answer:

Equation: 1.5s + 20 = 200

How long it will take for Samantha to finish a 200 meter race: 120 seconds

Step-by-step explanation:

The problem says Samantha walks at a rate of 1.5 meters per second. If we let "s" represent seconds, then we can write this as 1.5s. Since she gets a 20 meter head start, you can then write the equation as 1.5s + 20. Finally, its says use this equation to find how long it would take to finish a 200 meter race. So you set the previous equation equal to 200. Or 1.5s + 20 = 200.

To solve for "s" and find how long it would take to finish a 200 meter race, you first subtract 20 from each side. You should be left with 1.5s = 180. Then divide by 1.5. 180/1.5 equals 120. So it will take Samantha 120 seconds to finish the 200 meter race.

Julie is tracking the growth of a plant for a science project. The height of the plant on the 2nd day she measured was 8 inches
kvv77 [185]

Answer:

Step-by-step explanation:

The relationship is linear, so the plant grows the same amount each day.

The height on the 2nd day was 8 inches:

h₂ = 8

The height on the 7th day was 20.5 inches:

h₇ = h₂ + (7-2)d = 8 + 5d = 20.5

d = 2.5

The plant grows 2.5 inches each day.

Answer:

A. 60°

Step-by-step explanation:

There's a very straight-forward explanation for this, thank god! XD

For this type of problem, there's a rule to follow for the outside angle. X and 120 should equal 180, so all you need to do is fill that gap.

180-120 = 60

60 is your answer because it completes the whole angle.
