Answer:

-3 1/4 =n

Step-by-step explanation:

First you want to make it so that all of the fractions have the same demominator.

-10/4=3/4+n

Then you solve.

-10/4=3/4+n Subtract 3/4 from both sides

-13/4=n Simplify

-3 1/4=n Your answer is -3 1/4=n

Short answer (Assuming you are trying to find the value of n):

Equation solution: -2.5

Value of n: -3.25

I assume you wanna find the value of n

First step is to do the first equation

remember that that / sign is division

-5 divided by 2 = -2.5

Now start the equation with n

3 divided by 4 = 0.75

so n must be a negative because that is the only way the number will go into the negatives when your adding

Since subtracting a positive is the same as adding a negative, we can just find the number that when subtracted from 0.75 gives us -2.5 and flip the sign.

0.75 - 3.25 = -2.5

Your answer is -3.25

Find the lengths of the missing side . Simplify all radicals !!! help mee!!!!!!

Answer:

$e = 13\sqrt{2}$

$f = 13\sqrt{2}$

Step-by-step explanation:

The ∆ given is an isosceles ∆ with a right angle measuring 90°, and two congruent angles measuring 45° each.

Using trigonometric ratio formula, we can find the lengths of the missing side as shown below:

Finding e:

$sin(\theta) = \frac{opp}{hyp}$

$sin(\theta) = sin(45) = \frac{\sqrt{2}}{2}$

hyp = 26

opp = e = ?

Plug in the values into the formula

$\frac{\sqrt{2}}{2} = \frac{e}{26}$

Multiply both sides by 26

$\frac{\sqrt{2}}{2}*26 = \frac{e}{26}*26$

$\frac{\sqrt{2}}{2}*26 = e$

$\frac{\sqrt{2}}{1}*13 = e$

$13\sqrt{2} = e$

$e = 13\sqrt{2}$

Since side e is of the same length with side f, therefore, the length of side f = $13\sqrt{2}$

What is the limit as x is approaching 0 of the absolute value of x

vesna_86 [32]

Recall that, an absolute value expression is a piece-wise in effect, thus we'd check the single-sided limits,

$\bf \lim\limits_{x\to 0}~|x|\implies 
\begin{cases}
\lim\limits_{x\to 0^-}~-x\\\\
\lim\limits_{x\to 0^+}~+x
\end{cases}\implies 
\begin{cases}
0\\\\
0
\end{cases}\implies \lim\limits_{x\to 0}~|x|=0$

I have 2 questions. 1. Find the mode and the median for this data set. 5,7,5,8,9,5,8. 2. Write 543.24 in expanded form.

katen-ka-za [31]

To find the median, put the numbers in order to least to greatest, which would be 5, 5, 5, 7, 8, 8, 9. the median is the number in the middle, which is seven. the mode is the number that occurs most often in the set, which is 5 in this case (appears three times). 2. 543.24 in expanded form is essentially pulling the number apart into its different values places. in this case, it would be five hundred plus forty plus three plus two tenths plus four hundredths, which is 500 + 40 + 3 + .2 + .4. hope this helps!

Please answer i need help please i will give you brainlest please

Shkiper50 [21]

Answer:

14) 4x+10=8x-26 (corresponding angles are equal)

4x-8x=-26-10

-4x=-36

x= -36/-4= 9

x=9

15) perimeter of rectangle= 2(l+b)

2( l+ $\frac{2l}{3}$ ) = 40m

2l+ $\frac{4l}{3}$ =40

Take LCM as 3

$\frac{2l}{1}$ * $\frac{3}{3}$ + $\frac{4l}{3}$ =40

$\frac{6l+4l}{3}$ = 40

$\frac{10l}{3}$ = 40

10l=40*3

10l = 120

l= 120/10 =12 cm

l=12cm

b= 2/3 *12 = 8cm

16) 2:3:4

It can be written as 2x+3x+4x

sum of angles of a triangle =180 degree

so 2x+3x+4x=180

9x=180

x=180/9=20 degree

1st angle=2x=2*20= 40 degree

2nd angle= 3x=3*20 =60 degree

3rd angle= 4x=4*20= 80 degree

17) sum of interior angles of a pentagon is 540 degree

so, 125+88+128+60+x=540 degree

401 +x= 540 degree

x=540-401= 139 degree

Hope this helps
