Helpppp I need to turn this in ASAP
Well, this should be a bit easy.
We can move the negative sign to the denominator:[tex] \frac{3}{-8}[/tex]
We can also multiply the entire fraction by an integer.
( I would perfer [tex] \frac{3}{-8}[/tex] as the answer)

Find the weighted average of these values.
Value Weight
5.005.00 75.0%75.0%
6.006.00 15.0%15.0%
7.007.00 10.0%10.0%
Answers:
The Weighted Average = 5.35
Explanation:
The weighted average is given by:
W(avg) = v1*w1 + v2*w2 + v3*w3
v1.v2.v3 are the values
w1,w2,w3 are the weights
W(avg) = 5.00*0.75 + 6.00*0.15 + 7.00*0.10
W(avg) = 3.75+0.9+0.7
W(avg) = 5.35
Hence, the weighted average is equals to 5.35

Please explain how this digraph works.
Angles XQL and MQR are congruent because they are vertical angles. So
209 - 13 b = 146 - 4 b
Solve for b :
209 - 13 b = 146 - 4 b
209 - 146 = 13 b - 4 b
63 = 9 b
b = 63/9 = 7
Then the measure of angle XQL is
(209 - 13*7)º = 118º

Answer:
See below.
Step-by-step explanation:
So we want to prove that:
[tex]\sqrt8+\sqrt2=3\cdot 2^{\frac{1}{2}}[/tex]
First, simplify √8. This is the same as:
[tex]\sqrt8=\sqrt{4\cdot 2}=\sqrt4\cdot\sqrt2=2\sqrt2[/tex]
Therefore, our equation is now:
[tex]2\sqrt2+\sqrt2=3\cdot2^{\frac{1}{2}}[/tex]
Combine like terms on the left:
[tex]3\sqrt2=3\cdot 2^\frac{1}{2}}[/tex]
The square root of something is the same as taking that number to the one-half power. Thus:
[tex]3(2)^\frac{1}{2}}=3\cdot 2^\frac{1}{2}}[/tex]
Rewrite:
[tex]3\cdot2^\frac{1}{2}}\stackrel{\checkmark}{=}3\cdot2^\frac{1}{2}}[/tex]
And we're done!

what is the first step to solve -2x+5x=9
Answer:
Step-by-step explanation:
Hello,
You need to group the terms in x
[tex]-2 \times x + \times x = (-2+5) \times x = 3 x[/tex]
And then, you can divide by 3 to find the solution
[tex]-2x+5x=3x=9<=>x=9/3=3[/tex]
Hope this helps
Answer:

You have to combine them
you have to subtract the -2x to the 5x
find the value of x. write your answer in simplest radical form
Answer:
[tex]x = 4 \sqrt{2} [/tex]Step-by-step explanation:
To find the value of x we can use either sine or cosine
Using cosine we have
[tex] \cos(\theta) = \frac{adjacent}{hypotenuse} [/tex]From the question
x is the hypotenuse
4 is the adjacent
We have
[tex] \cos45= \frac{4}{x} \\ x \cos45 = 4 \\ x = \frac{4}{ \cos(45) } [/tex]We have the final answer as
[tex]x = 4 \sqrt{2} [/tex]Hope this helps you

Find the equation of a line that is parallel to the line y = 3x and contains the point (1, -2).
e
y=(Type your answer in slope-intercept form.)
st
Answer:
y = 3x - 5
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
Step 1: Define variables
Slope m = 3
Random point (1, -2)
Step 2: Plug in known variables
y = 3x + b
Step 3: Find b
-2 = 3(1) + b
-2 = 3 + b
b = -5
Step 4: Write parallel linear equation
y = 3x - 5

The perimeter of a playing field for a certain sport is 190 ft. The field is a rectangle, and the length is 43 ft longer than the width. Find the dimensions
Answer:
2(L+w) = 190ft (Perimeter)
L + W = 95ft (190 divided by 2)
L = W + 43ft (Given)
W + 43 + W = 95ft
2W + 43 = 95ft
2W = 52ft
W = 26ft
L = 26ft + 43 = 69ft
Answer: The feild is 69ft by 26ft
