Hey there! I'm happy to help!
Let's set this up as a proportion (2 equal ratios).
If you multiply the diagonal numbers, their products will be equal. (412×g=103×184). This is called cross multiplying. Now we can solve for g.
412g=18952
Divide both sides by 412.
g=46
Therefore, the boat will need 46 gallons of gasoline to go 184 miles.
Have a wonderful day! :D
I need the stuff so i can help
Write the word problem in algebraic form:
n2 -14 = 5n
Write as a quadratic:
n2 - 5n - 14 = 0
Factor:
(n+2)(n-7) = 0
Solve:
n+2 = 0 => n = -2
n-7 = 0 => n = 7
positive solution is 7. (14 less than 72 = 35 which is also 5 times 7)
Answer:
6/4
Step-by-step explanation:
To multiply fractions you multiply straight across. Multiply the numerators together and the denominators together.
First make 2 have a denominator of 1---we just don't show it but it's there. Now you have:
2/1 * 3/4
Multiply straight across.
2 * 3 (numerators)
1 * 4 (denominators)
6/4 is the answer you get when you multiply the two fractions together. Move the dot to where it shows 6/4 on the number line.
