Evaluate. 47 + 2d, for d = 3

Answers

Final answer:

The problem evaluates the expression 47 + 2d, by substituting d = 3. This results in 47 + 2*3, which simplifies to 47 + 6. The final answer is 53.

Explanation:

This is a simple algebraic problem. The expression you're asked to evaluate is

47 + 2d

and you've been told to substitute

d = 3

. So substituting, we get 47 + 2*(3). The multiplication operation takes precedence according to the order of operations, so next we calculate 2*3 to get 6. Adding this to 47 gives us 53. Therefore, the solution to 47 + 2d, for d = 3, is 53.

Which expression is equivalent to the expression below?(6c^2+3c/-4c+2)/(2c+1/4c-2)

Answers

Answer:

-3c

Step-by-step explanation:

The given expression is:

$((6c^(2)+3c)/(-4c+2))/((2c+1)/(4c-2))$

We need to simplify this expression. The rational expression in the denominator can be multiplied to numerator by taking its reciprocal as shown below:

$((6c^(2)+3c)/(-4c+2))/((2c+1)/(4c-2)) \n\n =(6c^(2)+3c)/(-4c+2) * (4c-2)/(2c+1)\n\n=(3c(2c+1))/(-(4c-2)) * (4c-2)/(2c+1)\n\n =-3c$

Thus, the given expression in simplified form is equal to -3c

Answer:

-3c

Step-by-step explanation:

We are given that an expression

$((6c^2+3c)/(-4c+2))/((2c+1)/(4c-2))$

We have to find an expression which is equal to given expression

Taking common 3c from nominator and -2 from denominator in dividened and 2 common in divisor then we get

$((3c(2c+1))/(-2(c-2)))/((2c+1)/(2(2c-1)))$

$(3c(2c+1))/(-2(2c-1))* (2(2c-1))/((2c+1))$

By reciprocal divisor

By canceling same factor

Then ,we get

$((6c^2+3c)/(-4c+2))/((2c+1)/(4c-2))$

=-3c

10x-3-2x=4 solve the equation and show your work

Answers

therefore x = 7/8

A bank says you can double your money in 10 years if you put $1,000 in a simple interest account. What annual interest rate does the bank pay?

Answers

The simple interest formula allows us to calculate I, which is the interest earned or charged on a loan. According to this formula, the amount of interest is given by I = Prt, where P is the principal, r is the annual interest rate in decimal form, and t is the loan period expressed in years. The rate r must be converted from a percentage into decimal form.

Then, 2,000 = 1,000 * r * 10 ;
Finally, r = 2 ÷ 10 = 20 ÷ 100 = 0.02

The answer to this is 10%.

A grocery store so the six pack of bottled water for $3.79 a 12 pack for $6.89 which package cost The least per bottle explain your reasoning

Answers

Easiest way to find out the answer to this is to find out the price of every water bottle. To do that you have to divide the whole value by the amount of water bottles. (3.79/6 & 6.89/12) The first one should equal something around .63 each and the second should be around .57. Technically the second pack is cheaper than the other by around .6 cents.

What rational number represents a drop of 4 1/4 in.?

Answers

4 1/4 is a rational number

Final answer:

The rational number that represents a drop of 4 1/4 inches is either 4 1/4 as a mixed number or 4.25 as a decimal.

Explanation:

The question is asking for the rational number that represents a drop of 4 1/4 inches. A rational number is a number that can be expressed as a quotient or fraction of integers. In this case, 4 1/4 is already a rational number. However, if you want to express it as a decimal rather than a mixed number, you can convert it. Recall that 1/4 is equivalent to 0.25. Therefore, 4 1/4 can also be expressed as 4.25.
