Answer:
4x-13 = 2x+9 ( i think it was exterior angle property i dont remember but its true)
so, solving that eq,
4x-2x = 9+13 (grouping variables and constants)
2x=22
x=11
also, 2x+9 and 3y+2 are on a transversal, and are supplementary angles (add up to 180°)
so, solving for x in 2x+9,
2(11)+9 = 22+9 = 31°
now, 31 + 3y+2 = 180
3y = 180 - 33
y = 147/3 = 49
(hoping you understood the calculations :)
Answer:
The answer is -1.8
Step-by-step explanation:
5 x -1.8 = -9 = -9 divided by -1.8 = 5
630 red marbles
420 yellow marbles
210 purple marbles
because 1260 x 1/2 = 630, 1260 x 1/3 = 420, 1260 x 1/6 = 210
Answer:
y = 9.8x + 6.7
y = 6.7x + 9.8
y = 7.5x + 3.8
y = 3.8x + 7.5
Step-by-step explanation:
I made 2represent x.
y= 9.8(2) + 6.7
y = 26.3
y=6.7(2) + 9.8
y= 23.2
y= 7.5(2) + 3.8
y= 18.8
y= 3.8(2) + 7.5
y= 15.1
