You can convert them to decimals and multiply. Remember when using decimals, it is over 10 or 100 <span />
Answer:
296 miles
Step-by-step explanation:
The total distance is the sum of the distance traveled so far and the distance left to go:
167 + 129 = 296
The total distance they must travel is 296 miles.
Subtract 4 from each side
Divide both sides by 5
Take square root of both sides
Add 3 to both sides
Same as the last one ! Review your parallel lines, and you'll see that angles A and B have to be equal. So you solve it EXACTLY the same way as the last one.
You say "A equals B", and that means that
8x - 10 = 3x + 90
Solve that to find x (it's 20),
and then use x to find angle B (it's 150; they both are).
(Don't just take my word for it. Please work it through.)
I’m pretty sure they are multiplied, if I understand your wording
