How to write the algebraic expression (2)(t) in words
Jlenok [28]

Answer:

"The number 8 multiplied by a number. "

"The product of 8 and a number"

"A number times the number 8"

Step-by-step explanation:

This is a long one,

You are going to write the expression using "key words"

Addition: sum, more than, plus, increase, add, older than.

Examples: 4+7

"The sum of 4 and 7"

"7 more than the number 4"

"The number 4 increased by 7"

Etc....

Subtraction: minus, less, subtract, decrease, younger than, and lowered.

Example: 9 - 2

"The number 9 decreased by 2"

"The number 2 younger than 7"

"The number 7 minus 2"

Etc....

Multiplication: times, product, twice, doubled, multiplied, and of.

Example: 4 × 5

"The number 4 multiplied by 5"

"The product of the numbers 4 and 5"

"5 times the number 4"

Etc...

Division: divided by and divided into and Quotient. Pay close attention to the order in which it is written.

Examples: 6 / 3

"The number 6 divided by 3"

"3 divided into the number 6"

Or

"The quotient of the numbers 3 into 6"

Ect...

Expressions with More Than One Operation example:

8y + 14 ...

You could say:

The sum of 8 times a number and 14.

When referring to unknown number i.e. x, y, n, v... you may refer to it a "a number"

Hmmm, best way I can describe it. :)

Please answer the two questions.
Anarel [89]

Answer:

1. n= 14

2. n=3

Step-by-step explanation:

For the first problem, let's break down the equation. The number being thought about can be represented by <em>n</em>. Then <em>n </em>is increased by 7, or simply put 7+ <em>n. </em>The sum is 21, so to find n you can use the equation 7 + n = 24 and solve for <em>n, </em>which is 14.

For problem two, the same strategy can be used. The number is <em>n, </em>multiplied by 9. So, 9 * <em>n</em> is equal to 27. Solve for n by isolating n, and the answer is 3.

A tank containing 64 gallons lost 6 1/4% of this through leakage how much is remaining is the tank
jolli1 [7]

if we take 64 to be the 100%, how much is 6¼% off of it?

\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 64&100\\ x&6\frac{1}{4} \end{array}\implies \cfrac{64}{x}=\cfrac{100}{6\frac{1}{4}}\implies \cfrac{64}{x}=\cfrac{\frac{100}{1}}{\frac{25}{4}}\implies \cfrac{64}{x}=\cfrac{100}{1}\cdot \cfrac{4}{25} \\\\\\ \cfrac{64}{x}=16\implies 64=16x\implies \cfrac{64}{16}=x\implies 4=x \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{it had}}{64}-\stackrel{\textit{leakage}}{4}\implies \stackrel{\textit{remaining}}{60}
