I'm assuming we need to simplify this expression. (Tip when you are writing n squared, please write n^2, not n2.)
Since we can see that there is a 5 in each term inside the ( ), we simplify have to remove that if the whole thing is going to be divided by 5.
Answer:
(15n^2-5n+45)/5
=3n^2-n+9
Answer:
3n^2-n+9
Step-by-step explanation:
You would want to divide the 5 between each of the terms. 15n^2 ÷ 5 is 3n^2. 15 ÷ 5 is 3. The n^2 stays, so 3n^2. -5 ÷ 5 is -1. We don't have to worry about writing the -1. Rather, just write the -n, it is the same as writing -1n. Lastly, 45 ÷ 5 is 9. You have to put the terms together in standard form. Standard form is just writing the numbers from greatest power to least power. The 3n^2 would come first since 2 is the greatest power. Next would be the -n, and lastly the 9. The 9 is the constant, which always comes last. A constant would be a number without a variable after it, like 2x is not a constant but just 2 is. Therefore, the answer is 3n^2-n+9.
How many 1/9's in 31
There are a total of 279 1/9s in 31.
What is simplification?Simplifying procedures is one way to achieve uniformity in job efforts, expenses, and time. It reduces diversity and variation that is pointless, harmful, or unneeded. Parenthesis, exponents, multiplication, division, addition, and subtraction are all referred to as PEMDAS. The order of the letters in PEMDAS informs you what to calculate first, second, third, and so on, until the computation is finished, given two or more operations in a single statement.
To find out how many 1/9's are in 31, you can divide 31 by 1/9.
This can be simplified by converting the division of a fraction to multiplication with its reciprocal:
31 ÷ (1/9) = 31 × (9/1)
Simplifying the expression on the right side gives:
31 × 9 = 279
So there are 279, 1/9's in 31.

The pitchers that Isaac bought for the party each hold 2 quarts of liquid. If he makes 15 pints of smoothie and has three pitchers, how much of the smoothie will not fit into the pitchers?
quart and pint
Answer:
3 pints or 1.5 quarts
Step-by-step explanation:
1 quart has 2 pints, so each pitcher holds 4 pints -- 12 pints all together. So 15-12 = 3 pints that will not fit into the pitchers. 3 pints is equal to 1.5 quarts!

A box contains 12 cereal bars. The empty box weighs
1.75 oz. The box and the bars weigh 18.55 oz. what is the weight of each cereal bar?
please answer asap!!!
Answer:
1.4oz
Step-by-step explanation:
You subtract the weight of the box and the bars with the empty box. Then divide the answer you got from that, with 12 and you get your answer.
The weight of each cereal bar is 1.4 oz.
What is an equation?"It is a statement which consists of equal symbol between two mathematical expressions."
For given example,
Let 'x' be the weight of single cereal bar.
A box contains 12 cereal bars.
The empty box weighs 1.75 oz.
The box and the bars weigh 18.55 oz.
This means the the total weight of the box is:
total weight = weight of the empty box + weight of 12 cereal bars
So, we get an equation,
⇒ 18.55 = 1.75 + ('x' × 12)
We solve above equation to find the weight of each cereal bar.
⇒ 18.55 = 1.75 + 12x
⇒ 12x = 16.8
⇒ x = (16.8)/12
⇒ x = 1.4 oz.
Therefore, the weight of each cereal bar is 1.4 oz.
