Answer:
first one
Step-by-step explanation:
if you plug the inputs into the equation, you can see that all of the outputs match the ones in the first chart
0 --> 2
1 --> -1
2 --> -4
Together it would take 3 hours.
Team A can wrap all gifts in 7 hours; thus they can wrap 1/7 of the gifts in 1 hour.
Team B can wrap all gifts in 5 hours; thus they can wrap 1/5 of the gifts in 1 hour.
1/7h + 1/5h = 1, where h is the number of hours; it equals 1 because it is 100% of the gifts;
Find a common denominator. 35 is the first thing 7 and 5 will both divide into. Convert the fractions:
5/35h + 7/35h = 1
12/35h = 1
Divide both sides by 12/35:
12/35h ÷ 12/35 = 1 ÷ 12/35
h = 1/1 ÷ 12/35
h = 1/1 × 35/12
h = 35/12
h = 2.9
h ≈ 3
Answer:
1. -|12|
2. -5
3. -1
4. |-1|
5. 12
Step-by-step explanation:
Answer:
9
Step-by-step explanation:
they said that m=6 which you can plug in into the problem, now that you know what 'm' is. It will look like this:
6/2 + 6 = ?
6 divided by 2 = 3 so it'll look like this
3 + 6 = 9
