Answer:
6
Step-by-step explanation:
(4/5)-(x/9)=6/45
6/45=(6/3)/(45/3)=2/15
4/5-(x/9)=2/15
(4/5)-(2/15)=(x/9)
(4*3)/(5*3) = 12/15
12/15-2/15=10/15
10/15=2/3
2/3=6/9
Answer:
Y=-4x
Step-by-step explanation:
We know the slope is negative since the line decreases from left to right. Starting at 0,0 we go down 4 and to the right 1 to get to the next point. Therefore the slope is the change in y over the change in x or -4/1= -4. The y intercept is 0 since it crosses the y axis at 0,0. The equation of the line in slope intercept form is y= mx+b or y= -4x

23/4
Step by step:
5/1 + 3/4
5/1 • 4 = 20/4
20+3/4
23/4
Answer:
r=3
Step-by-step explanation:
3(r - 7) = 4(2 - 2r) + 4
Distribute
3r -21 = 8 -8r +4
Combine like terms
3r -21 = 12 -8r
Add 8r to each side
3r +8r-21 = 12 -8r+8r
11r -21 = 12
Add 21 to each side
11r -21+21 =12+21
11r = 33
Divide each side by 11
11r/11 = 33/11
r = 3
