here 8x and (2x+60) are corresponding angles
since line l1 and l2 are parallel, so the two angles will be equal
8x=2x+60
8x-2x=60
6x=60
dividing by 6
x=10
option D. 10 is correct
I just need points u don’t know what to put so fidgdbdjdudvbdjdgdbdjdvdndjdgsndkdjbddbdnnddndndj
Answer:
2) x = 6 y = 7 3) x = -5 y= 2
Step-by-step explanation:
2) 10x - 8y = 4
2(-5x + 3y = -9)
-10x + 6y = -18
10x - 8y = 4 Add both equations together
-2y = -14
y = 7 Divide both sides by -2
10(x) - 8(7) = 4 Plug in 7 for the y to solve for x
10x - 56 = 4
+ 56 + 56 Add 56 to both sides
10x = 60
x = 6 Divide both sides by 10
3) Where the two lines intersect, that is the solution to x and y.
The lines intersect at (-5,2). x = -5 y = 2
A+3=B
17+3=B=20
B equals 20 when A equals 17
1) -10, 0
2) 20
4) 24 minutes
7) 25 floors
10) 9 baskets ( I'm not great at GCF )

Hope this helps. Sorry if I got some wrong (specifically 10)
