Convert the measurement as indicated.
grigory [225]

Answer:

7 gal 3 qt is 31 quarts.

Step-by-step explanation:

Given:

7 gal 3 qt to quarts.

Now, convert the measurement as indicated.

So, the value of 1 gallon = 4 quarts.

Thus , the 7 gal(gallons) = 7 × 4 = 28 quarts.

And 3 qt (quarts) = 3 × 1 = 3 quarts.

So,

7\ gal\ 3\ qt

=28 quarts+3 quarts

=31 quarts.

Therefore, 7 gal 3 qt is 31 quarts.

What is<br> is 1/4 + 9/10y -3/5y +7/8 written in simplest form?
Leviafan [203]

Answer:

Step-by-step explanation:

\frac{1}{4}+\frac{9}{10}y - \frac{3}{5}y+\frac{7}{8}\\\\=\frac{1}{4}+\frac{7}{8}+\frac{9}{10}y-\frac{3}{5}y\\\\

Combine like terms. 1/4 and 7/8 are like terms and LCD of 4 and 8 is 8

9/10y and -3/5y are like terms and LCD of 10 , 5 is 10

= \frac{1*2}{4*2}+\frac{7}{8}+\frac{9}{10}y-\frac{3*2}{5*2}y\\\\=\frac{2}{8}+\frac{7}{8}+\frac{9}{10}y-\frac{6}{10}y\\\\=\frac{9}{8}+\frac{3}{10}y

What is the factored form of the expression. (2n^2 + 5n + 3) (4n - 5)
7nadin3 [17]

So firstly, <u>the factor (4n - 5) cannot be further factored, so we will be focusing on 2n² + 5n + 3.</u>

So for this, we will be factoring by grouping. Firstly, what two terms have a product of 6n² and a sum of 5n? That would be 2n and 3n. Replace 5n with 2n + 3n:

(2n^2 + 2n + 3n + 3)(4n - 5)

Next, factor 2n² + 2n and 3n + 3 separately. Make sure that they have the same quantity on the inside of the parentheses:

(2n(n+1)+3(n+1))(4n-5)

Now we can rewrite this expression as<u> (2n+3)(n+1)(4n-5) , which is your final answer.</u>
