A number problem states, “–5 times a number, minus 22 gives a result of 23.” What is the number?
Serggg [28]

Answer:

im pretty sure its -9

Step-by-step explanation:

the equation explained would look something like this...

-5x-22=23

so you would isolate the variable by first adding 22 to both sides and the dividing by -5 on both sides

-5x-22=23

Answer for brainlest and 25 points
nordsb [41]

Answer:

Order from greatest to least: 10.5, 3\pi +1, \sqrt{105}

Step-by-step explanation:

step 1 simplify each number

3π + 1  = 10.4247779

*round to the nearest tenth*

3π + 1 = 10.4

\sqrt{105} =10.2469507

*round to the nearest tenth*

\sqrt{105} =10.2

10.5 = 10.5

Now that we have simplified each number we can easily put them in order from greatest to least

10.5 is the greatest number

10.4 is the middle number

10.2 is the lowest number

so 10.5, 10.4, 10.2

Now we put them back in the original form

10.5 = 10.5

10.4 = 3π + 1

10.2 = \sqrt{105}

Your answer is

10.5 , 3\pi + 1, \sqrt{105}

Admission to the zoo costs $15 per person. Which graph correctly represents the total cost for a group to visit the zoo? Total C
vampirchik [111]

Admission to the zoo costs $15 per person.

The graph y = 15x correctly represents the total cost for a group to visit the zoo.

Given;

Admission to the zoo costs per person = $15

Let:

The total number of people visiting the zoo = x

The total cost for a group to visit the zoo = y

So,  y ∝ x

y = 15x

Therefore, the graph y = 15x correctly represents the total cost for a group to visit the zoo.
