Answer:
First one
Step-by-step explanation:
.20 is 20% of 100 and there is 5 boxes and 5 times 20 = 100
Answer:
1)
=0.3571428571 2) Terminating
Step-by-step explanation:
1st. To answer this question let's divide with long division algorithm 5 and -14.

5 (dividend) : -14 (divisor) 
Long division (check below)
With the same two numbers -14 and 5 we can write in a Long Division
5) -14
<u> - 2.8</u>
5) -14
10
40
So 
2nd. Both are terminating ones for they have finite quantities of numbers. -2.8 and 0.3571428571, as we can see that these are rational numbers for they can be written as a/b, and b≠ 0.

Answer:
52 years old
Step-by-step explanation:
let this mans age be a
400-3a=244
400=244+3a
400-244=3a
156=3a
a=52
Answer:
3
Step-by-step explanation:
Answer:
6
Step-by-step explanation:
so this is (base times hight)
(bH)
42=7x
you didvide 7 from both sides
42 divided by 7 is 6
so basically its 6
because that would be your base thats what you are missing
then its just baseically (BH) (7 times 6)= 42
if this is wrong im so sorry I just learned this good luck
