18(x)=100×43.
18(x)=4300.
Now divide both sides by 18. The number is x=238<span>.</span>
A-Step 1 Multiply 18.9 × 3.
Step 3. Add 18.9 from the product. is the right answer. Why?
This week the distance travelled was 3x 18.9 father than last week, it means
18.9x3 + 18.9=75.6
Ah hah ! You said in there "race AGAIN". Tell us something about how the first race turned out, and we may have some information we can use to answer with. Right now we got nuttn.
Remember that parallel lines have the same slope.
y=3/7x+11 (in slope intercept form already)
-3x+7y=13 (standard form)
Add 3x to both sides, giving you 7y=3x+13, divide by 7 on both sides, giving
y=3/7x+13/7
Since both equations' slopes' are the same, their graphs will be parallel.
