Answer:
0.125, or 1/8
Step-by-step explanation:
We must evaluate 1/4-1 first, because this is inside parentheses (think:
1/4 - 1 = -3/4. order of operations rules (PEMDAS)
Thus, we have:
0.3(-3/4)+0.35 and must carry out the multiplication before the addition:
0.3(-0.75) + 0.35 =
-0.225 + 0.35 = 0.125, or 1/8
Answer:
72
Step-by-step explanation:
Find the LCM
6=2x3
8=2x2x2
9=3x3
12=2x2x3
LCM=2³x3²
=72
Sarah: School to mall = 21
mall to library = 20
Total distance for Sarah = 20 + 21 = 41 miles.
Use the Pythagorean theorem to find the distance Bret traveled:
Distance = SQRT(21^2 + 20^2)
= sqrt(441 + 400)
= sqrt(841)
= 29 miles
Total distance = 41 + 29 = 70 miles
Answer is D. 70 miles.
1. 56.4
2.107.15
So for the first one I subtracted like this:53.41- -2.99=56.4
You may be wandering why i subtracted that way,I did that because you are meant to subtract and the second number already has a negative sign which is MINUS.
And for the second I subtracted the smaller number from the bigger number this way:144.96 ‐ 37.8
Hope this helps...
