someone please help me with this

Answer:

a. 42

b. 122

a. 57

b. 130

Step-by-step explanation:

For problem A:

because both of these values have positive numbers, just use normal subtraction

82 - 40 = 42 degrees warmer

For problem B:

because we are subtracting a negative number from a positive number, we add both of these numbers because 82 - -40 can also be equal to 82 + 40

82 - -40 = 122

For problem A:

the sentences 30m up a cliff and 87m up a cliff are describing positive values.

87 - 30 = 57

For problem B:

Now in this problem, the sentence 100m above the surface is describing a positive value, but the sentence 30m below the surface describes a negative value

how do I know this?

if the sentences above the surface and below the surface are describing positive and negative values, then there has to be a neutral value ( which is 0)

0 meters = the surface, because they are using both positive and negative values, meaning that the surface is the neutral value

by using a number line, you can draw it out like this

below the surface-------------------------the surface----------------------------above the surface

-30--------------------------------------------0--------------------------------------------100

therefore, 100 - - 30 = 100 + 30 = 130

Answer:

Step-by-step explanation:

I'm not sure this task part of geometry or trigonometry.

Now, the solution with trigonometry functions

[tex]\frac{x}{\sqrt{3} }[/tex] = cos 30°

[tex]\frac{x}{\sqrt{3} }[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex]

x = [tex]\frac{\sqrt{3} *\sqrt{3} }{2}[/tex] = [tex]\frac{3}{2}[/tex]

there is no pic -_-

Answer:

Step-by-step explanation:

9x - 8 = 6x + 4

3x - 8 = 4

3x = 12

x = 4

Answer:

9x - 6x = 4 + 8

3x = 12

x = 12÷ 3

x = 4

Step-by-step explanation:

restamos las variables, verificamos que 9x es mayor que 6x por lo cual lo trasladamos al lado del 9x. Lo cual sería 9x menos 6x , por el lado del menos ocho y el cuatro, al menos ocho lo volvemos positivo lo cual da 4 más 8. y así

9x - 6x = 4 + 8

3x = 12

x = 12÷ 3

x = 4

16+23=39

180-39=151

Answer:

151

Answer: 26

Step-by-step explanation:

10^2 + 24^2 = c^2

100 + 576 = 676

sqrt of 676 = 26

Answer:

f=26

Step-by-step explanation:

So its a right triangle so we can use the Pythagorean theorem since we’re finding sides. We got 2 sides already which is 10 and 24. Follow the formula of a^2+b^2=c^2. In this case we don‘t have the hypotnuse and only the a and the b so we plus them in. 10^2+24^2=c^2.

10^2=100

24^2=576

Add them up and get 676

FInd the square root of 676

√676= 26

Step-by-step explanation:

Answer:

(-3b) (10a -3b)

Step-by-step explanation:

(5a–3b)^2–25a^2

Replace (5a–3b) with x

x^2 - (5a) ^2

We have the difference of squares

( x-5a) (x+5a)

Now replace x with (5a -3b)

(5a -3b -5a) ( 5a -3b +5a)

Combine like terms

(-3b) (10a -3b)

Answer:

(5a-3b)²-25a²

= 25a²+9b²-2×5a×3b-25a { (a-b)²= a²+b²-2ab}

=9b²-30ab

=3b(3b-10a)

= -3b(10a-3b)

Answer:

2x+6y=-2 x is -3y-1 and 5x-3y=31 x is 3y+31/5

Step-by-step explanation:

5x−3y=31

Add 3y to both sides.

5x=31+3y

The equation is in standard form.

5x=3y+31

Divide both sides by 5.

5

5x =  5

3y+31

​Dividing by 5 undoes the multiplication by 5.

x=  5

3y+31

Answer:

[tex]Probability = \frac{1}{9}[/tex]

Step-by-step explanation:

Given

Toppings: Pico de gallo, Onions and Steak

Required

The probability of getting Onions and Steak

The probability is calculated using:

[tex]Probability = P(Onion)\ and\ P(Steak)[/tex] --- because the events are independent

[tex]P(Onion) = \frac{n(Onion)}{Total}[/tex]

[tex]P(Onion) = \frac{1}{3}[/tex]

[tex]P(Steak) = \frac{n(Steak)}{Total}[/tex]

[tex]P(Steak) = \frac{1}{3}[/tex]

So, we have:

[tex]Probability = P(Onion)\ and\ P(Steak)[/tex]

[tex]Probability = P(Onion)\ *\ P(Steak)[/tex]

[tex]Probability = \frac{1}{3} * \frac{1}{3}[/tex]

[tex]Probability = \frac{1}{9}[/tex]
