9 (k - 2) = -6

k = ?

Answer:

The correct answer is C. 126 units².

Step-by-step explanation:

To solve this problem, we must first realize that this figure is a trapezoid. To find the area of a trapezoid, we should use the following formula:

Area = 1/2(b1 + b2)*h

In this formula, b1 and b2 represent the two bases of the trapezoid and h represents the height.

The height of the trapezoid is 9 units, and the bases are 16 units and 12 units.

Plugging in these values, we get:

A = 1/2(16 units + 12 units)(9 units)

A = (1/2)(28 units)(9 units)

A = 14 units * 9 units

A = 126 units²

Therefore, the correct answer is C. 126 units².

\(\frac{x}{3} - 2 + \frac{x}{2} + 6 = 3\)

\(\frac{1}{3} x + -2 + \frac{1}{2} x + 6 = 3\)

Answer:

2n² + 5n - 102 = 0

n = 6

Step-by-step explanation:

The formula for the area of a rectangle is:

\(\boxed{A=w \cdot l}\)

where w is the width and l is the length.

From inspection of the given rectangle:

Given that the area of the rectangle is 90 cm², then A = 90.

Substitute the values of A, w and l into the formula:

\(\implies 90=(n+4)(2n-3)\)

Switch sides:

\(\implies (n+4)(2n-3)=90\)

Expand the left side of the equation using the FOIL method:

\(\implies 2n^2-3n+8n-12=90\)

\(\implies 2n^2+5n-12=90\)

Subtract 90 from both sides:

\(\implies 2n^2+5n-12-90=90-90\)

\(\implies 2n^2+5n-102=0\)

To solve a quadratic in the form ax² + bx + c, find two numbers that multiply to ac and sum to b.

\(\implies ac=2 \cdot (-102)=-204\)

\(\implies b=5\)

Two numbers that multiply to -204 and sum to 5 are:

Rewrite b as the sum of these two numbers:

\(\implies 2n^2+17n-12n-102=0\)

Factor the first two terms and the last two terms separately:

\(\implies n(2n+17)-6(2n+17)=0\)

Factor out the common term (2n + 17):

\(\implies (n-6)(2n+17)=0\)

Apply the zero-product property:

\((n-6)=0 \implies n=6\)

\((2n+17)=0 \implies n=-8.5\)

n = -8.5 is an extraneous solution since this solution gives negative side lengths, which is impossible.

Therefore, the only valid value of n is n = 6.

\(\hrulefill\)

Check by substituting the found value of n:

\(\textsf{Width}=6+4=10\; \sf cm\)

\(\textsf{Length}=2(6)-3=9\; \sf cm\)

\(\textsf{Area}=10 \cdot 9=90\; \sf cm^2\)

Answer:

Step-by-step explanation:

The correct answer is (D) -2x - 8.

To simplify the expression -1/3 ( 6x + 15 ) - 3, we can first apply the distributive property to the term in parentheses:

-1/3 ( 6x + 15 ) - 3 = -1/3 * 6x - 1/3 * 15 - 3

Then we can simplify using the properties of multiplication and division:

-1/3 * 6x - 1/3 * 15 - 3 = -2x - 5 - 3

Finally, we can combine like terms:

-2x - 5 - 3 = -2x - 8

The correct answer is therefore (D) -2x - 8.✅

Answer:

11/24

Step-by-step explanation:

x=1-(3/8+1/6)

so

x=1-(13/24)=11/24

sorry if i need any.

Answer:

11/24

Step-by-step explanation:

you have to make the denominators the same.

to do that, you must find the LCM (Least Common Multiple) of the denominators which are 6 and 8.

Multiples of 6: 6, 12, 18, 24 (6 multiplied by 4 = 24)

Multiples of 8: 8, 16, 24 (8 multiplied by 3 = 24)

the LCM of 6 and 8 is 24 - this means that the smallest number that BOTH 6 and 8 can be divided into, WITHOUT leaving a remainder is 24.

From there, you multiply the ENTIRETY of each fraction by the number the denominator multiplies by to get 24:

3/8 multiplied by 3/3 = 9/24

1/6 multiplied by 4/4 = 4/24

NB: If you wish to check if your new and your old fractions are the same, all you have to do is simplify the new fractions and see whether or not you get back the old ones.

Next, you add the new fractions:

9/24 + 4/24 = 13/24

To get the allowance that she spent on other items:

24/24 (which is equal to 1 or 1 whole) - 13/24

This then results in 11/24 which is your answer

Answer:

We can start by using the formula:

time = distance / speed

Let t be the time (in hours) for Tom and Katherine to meet.

Tom's distance = Tom's speed x time = 14t

Katherine's distance = Katherine's speed x time = 10t

Since they are riding towards each other, the total distance they cover is the sum of their distances:

Tom's distance + Katherine's distance = 42 miles

14t + 10t = 42

Simplifying:

24t = 42

t = 42 / 24

t = 1.75 hours

Therefore, Tom and Katherine will meet after 1.75 hours of riding.

Option (C) Infinitely many solutions

you should know: in all means in total, so simply you add everything up.

answer:

1 + 2/4 + 3/4

- convert 1 to a fraction so its easier to add.

1 = 4/4 (must have the same denominator to add)

4/4 + 2/4 + 3/4

- add the numerators (top), NOT the denominators (bottom)

you get: 9/4 (this is an improper fraction, so you convert this into a mixed number)

9/4 = 2 1/4

Answer: Seki's interest rate for the bike is 33.33% each year; Seki will owe $8250 at the end of the loan.

Step-by-step explanation:

To calculate the simple interest rate, the equation is: r = (1/t)(A/P - 1)

Where:

r - interest rate per year (in decimal format)

t -time (loan time in years)

A - total accrued amount (initial price paid + amount of interest paid)

P - principle (initial price paid)

For this scenario:

r = (1 / 30)(8250 / 7500 - 1)

   - simplify both sets of parentheses: 1 / 30 and 8250 / 7500

r = (.033333)(1.1 - 1)

   - simplify the second set of parentheses

r = (0.033333) x 0.1

   - multiply

r = 0.0033333

   - convert r (as a decimal) to R (as a percentage) by multiplying r x 100

R = .3333

The interest rate on Seki's loan is 33.33%

The total amount Seki will pay:

equation for total due: A = P + I

Where:

A - total accrued amount (initial price paid + amount of interest paid)

P - principle (initial price paid)

I - amount paid in interest that accrued over time

For this scenario:

A = 7500 + 750

A = 8250

Seki will pay $8250 when the loan is due.
