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:
(0, 12)
Step-by-step explanation:
To find the y-intercept we just plug in x = 0 into the equation.
2(0) + 3y = 36
3y = 36
y = 12 which means the y-int. is (0, 12)
there is 128 fluid ounces per gallon so 1.5 gallons = 1.5 x 128 = 192 fluid ounces
Scotts cap holds 3 ounces so 192/3 = 64
Nikkis cap holds 4 ounces so 192/4 = 48
64-48 = 16 more caps for Scott
Subtract 3 from 30 gets you 27 then subtract 27-3 which equals 24 and so on
3(9) +4y=43
27 + 4y =43
-27. -27
4y=16
Divide 4 on each side
ANSWER: y=4
You have to go down in the order and end up trying to get y by itself.
