I believe the answer to that is true but im not to sure but i mean they just hae to have the same angle measure

Can you give me the answers to all of them, thank you

JulsSmile [24]

Answers:
22.)D
23.)D

How?
Explaining number 22:
Well, let’s disprove each one of them.
A.) A is saying 6x=7. Even if we simplify that, it wouldn’t make any sense in what we are trying to do. That equation is equal to x=0.86(estimated to nearest tenth)

B.) B says that 6x=3. When we simplify this, we get x=0.5. That isn’t the number we want, so we know B isn’t right

C.) C is equivalent to 2x+2=6. Let’s simplify since it is multi-step.
2x+2=6
2x=6
x=3
Since we want x to be six, this wouldn’t be the answer either.

D.) D is saying 2x=12. When simplified, this becomes x=6. BINGO THERE IS OUR ANSWER

Explaining 23:
For this, I also used process of elimination.

Remember that x is equal to 2.5

A.)
x+3=5.5

2.5+3=5.5
5.5=5.5
That works.

B.)
2x=5
2(2.5)=5
5=5
That works.

C.)
2.5/2=1.25
1.25=1.25
That works

D.)
x-10=7.5
2.5-10=7.5
-7.5=7.5
THAT DOESNT WORK THERE IS OUR ANSWER

After working for 6 hours kevin earned 51.00. what is kevin's unti rate

Ahat [919]

To find the unit rate, we need to divide 6 by 51.

51/6 = 8.50

Kevin earns $8.50 per hour

Given f (x) = x2 + 4x + 5, what is f of the quantity 2 plus h end quantity minus f of 2 all over h equal to?

meriva

By evaluating the quadratic function, we will see that the differential quotient is:

$\frac{f(2 + h) - f(2)}{h} = 8 + h$

<h3>How to get (f(2 + h) - f(2))/h?</h3>

Here we have the quadratic function:

$f(x) = x^2 + 4x + 5$

Evaluating the quadratic equation we get:

$\frac{f(2 + h) - f(2)}{h}$

So we need to replace the x-variable by "2 + h" and "2" respectively.

Replacing the function in the differential quotient:

$\frac{(2 + h)^2 + 4*(2 + h) + 5 - (2)^2 - 4*2 - 5}{h} \\\\\frac{4 + 2*2h + h^2 + 8 + 4h - 4 - 8 }{h} \\\\\frac{ 2*2h + h^2 + 4h }{h} = \frac{8h + h^2}{h}$

If we simplify that last fraction, we get:

$\frac{8h + h^2}{h} = 8 + h$

The third option is the correct one, the differential quotient is equal to 8 + 4.

A campground has cabins that can each hold 28 campers there are 148 campers visiting the campground.how many cabins are full if

Rainbow [258]

For this case, the first thing we must do is define variables.

We have then:

x: number of cabins

y: number of campers

We now write the equation that models the problem:

$y = 28x$

We know that there are 148 campers.

Therefore, substituting y = 148 in the given equation we have:

$148 = 28x$

From here, we clear the value of x:

$x = \frac{148}{28}\\x = 5.29$

Therefore, the number of full cabins is:

$x = 5$

Answer:

The number of full cabins is:

$x = 5$
