20 over 2 is like 20 divided by 2.
W--3 equals w+3 so then you subtract the 3 from both sides and get w=15
Answer:
8 2/3
<em>Y-E-E-T</em>
Step-by-step explanation:
-78 divded by (-9)
-78
-----
-9
there are negatives on both sides. I don't know how to explain that but you can change it to a PLUS.
78/9
divide 3 on both sides
78/3 =26
9/3=3
26/3 now.
so the mixed number would be 8 2/3
Answer:
Step-by-step explanation:
y = mx + b for line through (7, 4) and perpendicular to -5x + 9y = - 71
perpendicular lines have negative reciprocal slopes
-5x + 9y = - 71
9y = 5x - 71
y = (5/9)x - 71/9
so a perpendicular line will have slope -9/5
y = (-9/5)x + b
plug in our desired point
4 = (-9/5)7 + b
4 = -63/5 + b
20/5 = -63/5 + b
b = 83/5
y = (-9/5)x + 83/5
5y = -9x + 83
