Answer: 248 miles
Step-by-step explanation: The equation is x+2x+2x-60 where x is the mom and 2x is Dad and since dad drove 60 miles more than alex then Alex drove 60 miles less than dad so 2x -60 is alex. Altogether x+2x+2x-60 = 560 total miles driven and solved is x = 124 however x is just the mom. The dad drove twice as much so we have to double 124 or multiply by 2 to get the amount The dad drove which is 124*2= 248 miles
Answer:
Ben ate 1 1/2 more chocolate than Alice
Step-by-step explanation:
2 5/8 - 1 1/8 = 1 4/8
Simplify: 1 1/2
Ben ate 1 1/2 more chocolate than Alice.
in scientific notation, we leave only 1 digit to left of the decimal point.
now
35681000000 is really the same as 35681000000.0
so we can say the zero is way over there on the right-side, and we have to move it to the left, right in front of the "3", between "3" and "5", so the "3" is the only digit to the left of the decimal point.
to do that, we'll be moving it hmmmmm 10 slots over, therefore
35681000000
3.5681000000 x 10¹⁰
or
3.5681 x 10¹⁰ <---- using only significant digits.
