Twice a number increased by 5?? in algebraic expression

Answers

Answer 1

Answer:

To write this as an algebraic expression, remember that twice a number means that 2 is being multiplied by a number. Since we are not solving, we can just use the variable n to represent the number that is being multiplied by 2. Finally, adding 5 to the number we will get the expression 2n + 5.

Answer 2

Answer: 2x+5 would be the equation

x is the "number" that is unknown, it's what's called a variable. Because you need two times a number(x) you put a coefficient of 2 in front of it, then simply add 5.

Examples with known variable values:
2(4)+5=13
2(2)+5=9

If the ones digit of a number greater than 1 is 0,what factor or factors must that number have

Answers

If the units digit is zero, then you have an even number ...
' 2 ' must be one of its factors.

It must also have two or more places ... it's greater than 9.
If it had only one place, and its units digit were zero, then
the whole thing would be zero.

Since it has two or more places, 5 and 10 are also factors.

On Tuesday Shanice bought five hats. On Wednesday half of all the hats that she had were destroyed. On Tuesday there were only 17 left. How many did she have on Monday?

Answers

Answer:

So on Monday, Shanice had 29 hats.

Step-by-step explanation:

Let x be the number of hats that Shanice had on Monday.

We know that on Tuesday Shanice bought five hats.

On Wednesday half of all the hats that she had were destroyed.

On Thursday there were only 17 left.

We have the following equation:

$(x+5)/(2)=17\n\nx+5=17\cdot 2\n\nx+5=34\n\nx=34-5\n\nx=29$

So on Monday, Shanice had 29 hats.

Shantels net worth is 5,480.80 dollars.Her liabilities are 3,260.60.If she increases her assets by 10% and decreases her liabilities by 10%, what is her net work

Answers

Answer:

6681.00

Step-by-step explanation:

Given

Net worth = 5480.80
Liabilities = 3260.60

Assets = Liabilities + Net worth

Assets = 5480.80 + 3260.60 = 8741.40

If assets increase by 10% and liabilities decrease by 10%, then net worth is:

(8741.40 + 10%) - (3260.60 - 10%) =
8741.40*1.1 - 3260.60*0.9 =
6681.00

Solve the following inequality. Then place the correct answer in the box provided. Answer in terms of a mixed number. 3y + 5 < 10

Answers

y<1 2/5 So what you do is first subtract 5 from both sides to get the variable somewhat by itself, then divide by three to get the variable completely by itself, then you just see how many times 3 goes into 5 which is 1... 3, and there's 2 left over so you put that over 5

Final answer:

We solve the inequality 3y + 5 < 10 by subtracting 5 from both sides and then dividing by 3. This leads us to y < 5/3, meaning that y is less than 1 2/3 in terms of a mixed number.

Explanation:

The given inequality is 3y + 5 < 10. To find the value of y, we first subtract 5 from both sides to get 3y < 5. Then, we divide both sides by 3 to solve for y. This gives us y < 5/3. In terms of a mixed number, y is less than 1 2/3.

By mistake, you added salt instead of sugar to the
oil. How can you remove the salt?

Answers

Answer: Evaporate the water by boiling it in a pot with a lid or another container. This separates both substances as the boiling point for water is much lower than salt, this method is called simple distillation.

Answer:

Salt is ionic, and oil is covalent. If you add water, the salt will dissolve in the water, and the oil will float to the top. You could then skim the oil and start over with sugar. To double-check, you could even make sure the oil does not conduct electricity!
