Answer:


Step-by-step explanation:
For this mission, each astronaut will bring
- x pounds of food; and
- y pounds of gear.
Weight of Supplies of One Astronaut on the earth = (x+y) pounds
If the total number of astronauts going on the mission= a
- Total Weight on the earth of the supplies of all the Astronaut

On the moon, things weigh
of what they weigh on Earth.
- Total Weight of the supplies of all the Astronaut on the moon

Therefore,the inequality which correctly compares the weight of the supplies on the moon to the weight of the supplies on Earth is:


<u>if </u><u>we </u><u>ever </u><u>face </u><u>a </u><u>number </u><u>written </u><u>in </u><u>the </u><u>form </u><u>of </u>
<u>where </u><u>x </u><u>denotes </u><u>the </u><u>base </u><u>and </u><u>n </u><u>denotes </u><u>the </u><u>exponent</u><u> </u><u>or </u><u>power </u><u>,</u><u> </u><u>we </u><u>can </u><u>expand </u><u>it </u><u>in </u><u>the </u><u>following</u><u> </u><u>way </u><u>-</u>

Answer: 54.33%
<u>Explanation:</u>
14 carat gold contains 58.33% gold and 4% silver (since we are using the lowest percentage).
58.33% - 4% = 54.33%
There is 54.33% more gold than silver in the 14 carat gold mixture.
I think the answer should be B.
Answer:
600 miles.
Step-by-step explanation:
So basically we can write both plans as linear functions:
F(x) = $59.96+$0.14 . x
S(x) = $71.96+$0.12 . x
Where F(x) is the first plan, S(x) is the second one and X are the miles driven.
To know how many miles does Mai need to drive for the two plans to cost the same, we equalize both equations and isolate x.
F(x) = S (x)

Mai has to drive 600 miles for the two plans to cost the same-
