The sum of 17 and twice a number is 87. Find the number.

Answers

Answer 1
" the sum " means add

17 + 2x = 87

what is the answer to -12x+13x

Answers

-12x + 13x

If this is hard for you to solve, just switch the numbers.
13x - 12x

This gives you 1x, so the answer will be simply x.
-12x + 13x

Since both numbers have the same variable (x), then all you need to do is add the numbers together, and totally just ignore the variable.

What is -12 + 13?

-12 + 13 = 1

So, -12x + 13x = x

The slope-intercept form of the equation of a line that passes through point (–3, 8) is y = –x + 6. What is the point-slope form of the equation for this line?

Answers

y - 8 = -(x + 3)

hope this helps

Answer: The point slope form of the equation for this line is given by

[tex]y-8=-(x+3)[/tex]

Step-by-step explanation:

Since we have given that

The slope intercept form of the equation of a line is given by

[tex]y=-x+6-------------------(1)[/tex]

Line passing through a point is given by

(-3,8)

So, from the equation (1), we get that

m = Slope of line = -1

So, Point slope form of the equation of the line is given by

[tex]y-y_0=m(x-x_0)\\\\(y-8)=-1(x+3)\\\\y-8=-(x+3)[/tex]

Hence, the point slope form of the equation for this line is given by

[tex]y-8=-(x+3)[/tex]

The length of the base of an isosceles triangle is 2cm less than twice the length of any of its equal sides. If its perimeter is 98cm, what is its area?

Answers

Alright, so if the length of one of the equal sides are x, 2x-2 is the base and x+x+2x-2=98=4x-2. Adding 2 to both sides, we get 100=4x and dividing by 4 we get 25 as one of the equal sides and 48 as the base. Since we need to find the height to find the area, we can draw a line straight down the middle to form 2 right triangles, with the hypotenuse being 25 and the base being 48/2=24. Therefore, since a^2+b^2=c^2 and 24^2+b^2=25^2, we have

25^2-24^2=49=b^2. Square rooting both sides, we get b=7=height, and the base*height/2 is the area, so we get 48*7/2=168 as the area

At the beginning of January, Mr. Howard gives his niece $1 to start a savings account, for each month that she can triple the amount in the account, Mr. Howard will double the amount in the account at the end of each month. How much does Mr. Howard's niece in her account at the beginning of May?

Answers

Assuming the niece triples this every month without fail, then it would simply be (2*3)^x, where x is in months. In this case there are 5 months, so it would be (2*3)^5 = 7776 dollars

The requried, at the beginning of May (the fifth month), the niece will have $162 in her account.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

In the first month, the niece has $1 in her account.

In the second month, she triples that amount to have $3, and Mr. Howard doubles it to $6.

In the third month, she triples $3 to have $9, and Mr. Howard doubles it to $18.

In the fourth month, she triples $9 to have $27, and Mr. Howard doubles it to $54.

So at the beginning of May (the fifth month), the niece will have 54×3 = $162 in her account.

Rhonda deposited $4,227.29 into a savings account with an interest rate of 4.9% compounded monthly. About how long will it take for the account to be worth $9,000?

Answers

Final answer:

To find how long it will take for $4,227.29 to grow to $9,000 with a 4.9% interest rate compounded monthly, we use the compound interest formula rearranged to solve for time. The calculation involves using the natural logarithm to find the number of years required for the investment to reach the target amount.

Explanation:

The question pertains to determining how long it will take for a sum of money, specifically $4,227.29 deposited into a savings account with a 4.9% interest rate compounded monthly, to grow to be worth $9,000. We can use the formula for compound interest to solve for the time period required for the investment to reach the desired amount. This formula is A = P(1 + r/n)^(nt), where A is the amount of money accumulated after n years, including interest, P is the principal amount (the initial sum of money), r is the annual interest rate (decimal), n is the number of times that interest is compounded per year, and t is the time the money is invested for in years.

To find the time (t), we rearrange the formula: t = [log(A/P)] / [n*log(1 + r/n)]

Calculate the monthly interest rate r/n: 0.049/12Substitute the values into the formula:P = $4,227.29A = $9,000r = 0.049n = 12Use a calculator to compute the time t.

The calculation will provide the time in years, which can be multiplied by 12 to convert it to months, in case the answer is needed in months.

Which expression shows 12 more than the quotient of 63 and 9. A) 12 + 63 ÷ 9 B12 + 9 ÷ 63 C)(12 + 63) ÷ 9 D)(12 + 9) ÷ 63

Answers

Hey! Hope that I can help.

To do this, we need to notice the words being used. "More than" means adding on to the quotient of 63 and 9. "Quotient" means to divide 63 by 9 in this problem. Putting this into an expression gives us our answer.

Answer: A) 12 + 63 ÷ 9

The expression which shows 12 more than the quotient of 63 and 9 is option A) 12 + (63 ÷ 9).

We have to find the expression which shows 12 more than the quotient of 63 and 9.

For that, first find the quotient of 63 and 9.

Divide 63 by 9.

63/9 = 7

12 more than the quotient of 63 and 9 = 7 + 12 = 19

So the result is 19.

Now, we have to mathematically write the given word sentence.

12 is added to the quotient of 63 and 9.

12 is added to (63 ÷ 9)

12 + (63 ÷ 9)

Thus, A is the correct option.
