Can someone explain thes three questions and me solve hem

15. 200 - (8 * 18) = 56$

16. 8 - (5 * 3) = -7 °

17. 325 - (25 * 6) = 175$

Step-by-step explanation:

all three question have the same idea so I'll explain the first one,

you have 200$ and you subtract 18$ from them 8 times:

200 - 18 - 18 -18

which equals 200 - (18*8) = 56

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
