Thats good for Alex?
Haha, what is the rest of the question? I am happy to help
Answer:
A. No, the estimate should be higher
Step-by-step explanation:
To determine the maximum number of gallons of fuel the car can consume, we express this as;
Maximum miles driven=highest consumption per gallon×Maximum gallons
where;
Maximum miles driven per person=64 mile
Maximum miles driven=64×4=256 miles
highest consumption per gallon=24.56 miles per gallon
Maximum gallons=g
replacing;
256=24.56×g
24.56 g=256
g≥256/24.56=10.42 gallons
g≥10.42 gallons
No, the estimate should be higher
Let x represent number of bracelets and y represent number of necklaces.
We have been given that a jeweler made 7 more necklaces than bracelets. This means that number of necklaces will be
. We can represent this information in an equation as:

We have been given that the amount of gold in each bracelet is 6 grams, so amount used for x bracelets would be
grams.
We are also told that the amount of gold in each necklace is 16 grams, so amount used for y necklaces would be
grams.
Since the jeweler used 178 grams of gold, so we will equate the amount of gold used in x bracelets and y necklaces with 178 as:

Therefore, our required system of equations would be:
