Answer:
B, D
Step-by-step explanation:
36/40 simplified is 9/10
9/10 x 2 = 18/20
I hope this helps!
Answer: 1. x=2
2. x=5
3.x=-3
Isolate the variable by dividing each side by factors that don't contain the variable.
Move all terms not containing x to the right side of the equation.
Hope this helped
I cant see the image...but I take it that the midpoint is (9,8) and the endpoint S is (10,10) and ur looking for the other endpoint R.
midpoint formula : (x1 + x2) / 2, (y1 + y2) / 2
(10,10)....x1 = 10 and y1 = 10
(x,y)....x2 = x and y2 = y
so we sub
(10 + x) / 2, (10 + y) / 2 = 9/8
(10 + x) / 2 = 9
10 + x = 9 * 2
10 + x = 18
x = 18 - 10
x = 8
(10 + y) / 2 = 8
10 + y = 8 * 2
10 + y = 16
y = 16 - 10
y = 6
so endpoint R has coordinates of (8,6) <===
Answer is B: 150
write two equations
r+s=190
4r+3s=720
solve by substitution
the get r=150 s=40
Answer:
6
Step-by-step explanation:
Step 1: equal any two of the three equations together
2x + 3 = 3x - 9
Step 2: isolate the variable
3 = x - 9
6 = x
