Answer:
C ( 7, -3 )
Step-by-step explanation:
Question:
which point is 8 units away from ( 7, 5 ) ?
Choices:
A : (0,-3 )B (15,13) C ( 7, -3 ) D ( 1, 5 )
Solution:
(7, 5) and (7, 3) have the same x-coordinate, 7.
They are both on a vertical line that passes through point (7, 0).
(7, 5) is 5 units above the x-axis.
(7, -3) is 3 units below the x-axis.
5 + 3 = 8
(7, 5) and (7, 3) are 8 units apart.
Answer: C ( 7, -3 )
That would be c, or s-4p/4

4x➕6(503-x)=2296
Distribute the 6 into the parentheses
Let x represent the students
503-x will represent the non-students
4x➕3018➖6x=2296
Then combine like terms
-2x➕3018=2296
Now since you move your constant your sign has to change as well,
-2x=2296➖3018
Then subtract
-2x=-722
Then divide both sides by -2
You are left with x=361
This represents the students
503➖361= 142 which equal the non-students
Therefore your answer is:
361=students
142=non-students

Answer:
x = 3/4
Step-by-step explanation:
It usually works well to collect terms first. (Add the coefficients of x.)
-4x +x = -9/4
(-4+1)x = -9/4
-3x = -9/4 . . . . . . equation with terms collected
Now, you can divide by the coefficient of x. Here, it can be useful to consider this to be the same as multiplying by the inverse of that coefficient, which inverse is -1/3.
(-1/3)(-3x) = (-1/3)(-9/4) . . . . . multiply both sides by -1/3
x = 3/4 . . . . . simplify
