Step 2 is wrong and i don't know the other question
Answer:
The price of one gallon of gasoline is $3.15
Step-by-step explanation:
If the lady buys 2.4 gallons of gasoline for a total of $7.56, then as the problem suggests, one can find the unknown price of gasoline per gallon (p) by solving the equation for the unknown "p":
2.4 p = 7.56
then divide both sides by 2.4 to isolate the unknown "" on one side of the equal sign:
p = 7.56/2.4
p = $3.15
so this is the price per gallon of gasoline.
Answer:
-1.66666666667 yards
Step-by-step explanation:
15x+12=6x-3
subtract 6x on both sides
9x+12=-3
subtract 12 on both sides
9x=-15
x=-1.6666666666667
Answer:
This is not a triangle
Step-by-step explanation:
If you use the triangle inequality theorem you can reach your answer.
The theorem states that if you add the length of any 2 sides together, you will have a length greater than the length of the other side. Using this method we can easily see that 7+6=13 which is less than 21. Meaning this is not a triangle
