Question 1 (Essay Worth 10 points) (01.02 MC)The number line shows the distance in meters of two jellyfish, A and B, from a predator located at point X:

A horizontal number line extends from negative 3 to positive 3. The point A is at negative 1.5, the point 0 is labeled as X, and the point labeled B is at 0.5.

Write an expression using subtraction to find the distance between the two jellyfish. (5 points)

Show your work and solve for the distance using additive inverses. (5 points)

2.0

Step-by-step explanation:

Given that:

Number line : - 3 to +3

Point A = - 1.5

Point B = 0.5

Point X = 0

Point A = location of Jellyfish A

Point B = location of Jellyfish B

Distance between Jellyfish A and Jellyfish B:

Using Subtraction :

Point B - point A

0.5 - (- 1.5)

0.5 + 1.5

= 2.0

Using addition :

Absolute values of point A and B

1.5 + 0.5

= 2.0

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
