Write an algebraic expression for: The sum of ten and a number.
meriva

Hi,

The sum of ten and a number.

Usually AND refers to adding, that's just the rules of math according to writing equation. Times would be multiplying, taking away is subtraction and divided by is dividing.


So if the question uses AND, it's adding.

WILL GIVE BRAINLIST do i do 10-x=2?​
Viktor [21]

Answer:

x = 4

Step-by-step explanation:

DE is parallel to AC and intersects the other 2 sides. It divides those sides proportionally, that is

\frac{BD}{DA} = \frac{BE}{EC}, thus

\frac{10-x}{x} = \frac{3}{2} ( cross- multiply )

2(10 - x) = 3x ← distribute left side

20 - 2x = 3x ( subtract 3x from both sides )

20 - 5x = 0  ( subtract 20 from both sides )

- 5x = - 20 ( divide both sides by - 5 )

x = 4

Multiply.<br> (3b-5) (7b+1)<br> Simplify your answer.
mylen [45]
<h3>Answer:</h3>

It would be 21b² -32b -5

<h3>Step-by-step explanation:</h3>

By using the FOIL method, you can simplify the equation.

<em>The Foil Method is </em><u><em>ac + ad + bc +bd</em></u><em>, or </em><u><em>First, Outer, Inner, Last.</em></u>

First, you multiply the first term in each bracket.

3b * 7b = 21b²

Next, you multiply the outer term in each bracket.

3b * 1 = 3b

Then, you multiply the inner term in each bracket.

-5 * 7b = -35b

After that, you multiply the last term in each bracket.

-5 * 1 = -5

Lastly, you combine like terms.

21b² + 3b -35b -5 ---> 21b² -32b -5

<em>21b² -32b -5 would be your answer, since you cannot simplify the equation anymore.</em>
