Answer:

I can`t really see the question that well, but if I understand correctly here`s the first few.

1. Subtraction

2. Addition

3. Addition

4. Subtraction

5. Addition

6. Subtraction

It looks like its asking what is happening in those situations (is the number being added or subtracted). Sorry if that`s not much help

Find the mean 35 40 12 16 25 10

ruslelena [56]

Answer: Mean = 23

Step-by-step explanation:

Given information:

35, 40, 12, 16, 25, 10

Given formula:

$Mean~=~\frac{Sum~of~terms}{Number~of~terms}$

Substitute values into the formula

$Mean~=~\frac{35~+~40~+~12~+~16~+~25~+~10}{6}$

Combine like terms

$Mean~=~\frac{75~+~28~+~35}{6}$

$Mean~=~\frac{103~+~35}{6}$

$Mean~=~\frac{138}{6}$

Simplify the fraction

$\Large\boxed{Mean=23}$

Hope this helps!! :)

NEED HELP!!! Use what you know about special right triangles to find the missing measures. Show all calculations that lead to yo

Rasek [7]

Answer:a) a=22, b=11

b) m=7 $\frac{\sqrt{2} }{2}$ , n= $\frac{98-7\sqrt{2} }{2}$

Step-by-step explanation:

You should use trigonometry ratios as required and then you should use pythagoras theorem

In a) cosine(30°)= base/hypotenuse,

where 11√3 is the base

"a" is hypotenuse and

"b" is perpendicular

from this you can find the value of perpendicular then you should use pythagoras theorem to find the value of hypotenuse

pythagoras theorem is

base²+perpendicular²= hypotenuse²

Same is applied on (b) right triangle as, sine(45°)=perpendicular/hypotenuse

What is 3x eqauls -3x plus 2

sergiy2304 [10]

Answer:

x = $\frac{1}{3}$ or 0.33333333

Step-by-step explanation:

3x = -3x + 2 (Given)

3x + 3x= -3x + 3x + 2 (Addition Property of Equality)

6x = 2 (Simplify)

$\frac{6x}{6y} = \frac{2}{6}$

x = $\frac{1}{3}$ or 0.3333333

How do u write d dozen eggs in a numerical or varoable expression?

FromTheMoon [43]

Numeral expression is composed of numeric constants and operation while variable expression consist of both numeric and variables constants.
d dozen of eggs converted to numerical or variable expression:
=> There are 12pieces of eggs in 1 dozen, so that is 12x1=12
=> Therefore, the numerical value is 12 x d or simply 12d
