The correct answer is B, C and E
Answer:
196 children, 195 adults
Step-by-step explanation:
Use a for adults and c for children
a + c = 391
6a + 1.25c = 1415
Rearrange the first equation to be one variable alone:
a = 391 - c, then replace a in the second equation with that
6(391 - c) + 1.25c = 1415
2346 - 6c + 1.25c = 1415
2346 - 4.75c = 1415
-4.75c = -931
c = 196
There were 196 children admitted.
Now replace that into the original equation:
a + 196 = 391
a = 195 195 adults attended

Answer:
-4
Step-by-step explanation:
The slope is the number (& sign) attached to the variable x.
Remember to follow the slope-intercept form: y = mx + b.
Isolate the variable y. Note the equal sign, what you do to one side, you do to the other. ∴
First, add 4x to both sides:
-4x (+4x) - y = -5 (+4x)
-y = 4x - 5
Next, divide -1 from both sides (to make the variably y positive):
(-y)/-1 = (4x - 5)/-1
y = (4x - 5)/-1
y = -4x + 5
Slope intercept form: y = mx + b, in which m = slope, ∴ -4 is your answer.
