HELP PLEASE
Pls answer this question asap, I need help ;-;

4 seconds

Step-by-step explanation:

Rate : 0.4 feet per second = 0.4 ft / 1 second

To solve for the missing number in the ratio, set the ratio equal to the given rate:

3 = 0.75x

x = 3/0.75 = 4 seconds

0.3ft / 0.75 sec = 0.4 ft / 1 sec

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!

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
