Jessica measures two line segments using a metric scale. the first line segment is 30 centimeters long. the second line segment is 500 millimeters long. what is the total length, in centimeters, of the two line segments? question 2 options: a. 35 b. 80 c. 530 d. 800

B

Step-by-step explanation:

We need to convert millimeters to centimeters first:

We know,

10mm = 1 cm

Hence, 500 mm is cm

First line (30cm) PLUS second line (50cm) = 30 + 50 = 80 cm

Answer choice B is right

answer: .75 km

step-by-step explanation:

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
