51X2=102
51 goes into 102 evenly twice
So basically we're just looking for expressions equivalent to d - 12.50 = 17.
Let's look at each choice.
a.) d = 17 - 12.50
Try to make this look identical to d - 12.50 = 17
We can subtract 17 on both sides,
d = 17 - 12.50
- 17 - 17
We get:
d - 17 = -12.50
Subtract d on both sides
- 17 = -d - 12.50
or
-d - 12.50 = - 17
Divide -1 on both sides to all terms:
d + 12.50 = 17
Comparing this to d - 12.50 = 17, they do not look identical.
On to b): d = 17 + 12.50
Subtract 12.50 on both sides,
d - 12.50 = 17
This looks exactly like d - 12.50 = 17 so b) is the correct answer! :D
Answer:
a. False
b. False
c. False
d. True
e. False. (any number above 14.5 is a solution).
Step-by-step explanation:
12 + 6y > 99
6y > 87
y > 14.5.
Answer:
for the first one, go left 10, then down 7, and you have your point. for the second one, go left 5, then down 9, and you have your point.
Step-by-step explanation:
for the x-axis, negative means backwards
for the y-axis, negative means down
