Answer:

1/4

Step-by-step explanation:

Step 1 : Find a common denominator. We will use 36 as the denominator since 9, 12, and 18 are all factors of 36.

Step 2 : The number you multiple the denominator by must be the same number you multiply its numerator by.

Example : 2/9    To get a denominator of 36 you need to multiply 9 by 4. Now you need to multiply 2 by 4 as well.

Step 3 : Convert fractions into the new fractions

2/9 (times 4 on both sides) = 8/36

5/12 (times 3 on both sides) = 15/36

7/18 (times 2 on both sides) = 14/36

Step 4 : Plug new numbers into the equation.

8/16 + 15/36 - 14/36

Step 5 : Solve

8/16 + 15/36 = 23/36

23/36 - 14/36 = 9/36

Step 6 : Simplify

9/36 (divide by 9 on both sides) = 1/4

Answer:

Sam's student council spent $39 on backpacks + paper and pens.

Step-by-step explanation:

They bought 3 backpacks for $7 each. 3 x 7 = $21.

They also filled those backpacks with paper and pens costing $6 each. 3 backpacks x $6 = $18.

Now, add the two prices.

18 + 21 = 39

hope this helps :)

Diameter = 2 x radius

Area of circle formula: πr²

0.82/2 gives us the radius.

The radius is 0.41 so let's square that.

0.41²= 0.1681

Your answer is 0.1681π OR approximately 0.527834*

(*since 0.1681 times 3.14 is approximately 0.527834)

The 1st Graph (A)

Step-by-step explanation:

Test by substituting values for "x":

By substituting the numbers of 0 (0 < -3), -1 (-1 < -3), and -2 (-2 < -3), does that make the statement true?

The answer is FALSE. None of those values are satisfactory.

---

Therefore, by substituting -4 (-4 < -3), -5 (-5 < -3), and -6 (-6 < -3), these values are satisfactory and makes the statement true.

Answer:

11/3 ÷ 2/3 = 5 1/2

Step-by-step explanation:

When doing divison of fractions, you do these steps

11/3 ÷ 2/3 you turn the division sign to a multiplication sign, but by doing that you will have to turn 2/3 to 3/2.

11/3 × 3/2. Now all you have to do is multiply

11/3 × 3/2 = 33/6, simplify that down is 5 3/6, which is 5 1/2

The correct answer is B).

The single solution is [tex]log_\frac{1}{2} \frac{w^{4}u^{2} }{v^{3} }[/tex].

The exponent to which the base of the logarithm should be raised in order to obtain the number N is the logarithm of any number N, if interpreted as an exponential form. Numerous astronomical and scientific calculations involving large numbers can benefit from its use. As an inverse of the exponential function, logarithmic functions are closely related to exponential functions.

Given Equation

[tex]4log_\frac{1}{2} w + (2log_\frac{1}{2} u - 3log_\frac{1}{2} v)[/tex]

[tex]mlog_an = log_an^{m}[/tex]

equation is

[tex]log_\frac{1}{2} w^4 + (log_\frac{1}{2} u^2 - log_\frac{1}{2} v^3)[/tex]

and [tex]log_an - log_am = log_a\frac{n}{m}[/tex]

and [tex]log_an + log_am = log_amn[/tex]

[tex]log_\frac{1}{2} w^4 + (log_\frac{1}{2} \frac{u^2}{v^3} )[/tex]

and [tex]log_\frac{1}{2} \frac{w^{4}u^{2} }{v^{3} }[/tex]

Hence the equation is [tex]log_\frac{1}{2} \frac{w^{4}u^{2} }{v^{3} }[/tex].

3/4x + 3 -2x = -1/4 + 1/2x + 5

Combine like terms:

-1 1/4x + 3 = 1/2x + 4 3/4

Subtract 3 from both sides:

-1 1/4x = 1/2x + 1 3/4

Subtract 1/x from both sides

-1 3/4x = 1 3/4

Divide both sides by-1 3/4
