Which situation does this equation model? 18 × 3 = n Amelie earned 18 dollars selling lemonade. Raj earned 3 more dollars than Amelie. Raj earned n dollars. Natalie hopped on one foot for 18 seconds. This is 3 seconds longer than Rami hopped on one foot. Rami hopped on one foot for n seconds. Aisha collected 18 toys for a toy drive. This is 3 times as many toys as Eric collected. Eric collected n toys. Eloise practiced the piano for 18 minutes. Matthew practiced 3 times as long as Eloise. Matthew practiced for n minutes.

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

you can't solve x because it is 2 linear equation and you only have one equation
