7. f(x) = 2x + 5 What is the value of x if f(x) = 25 ?

Answers

Answer:

x=10

Step-by-step explanation:

set the 2 equations equal to each other

25=2x+5     -> subtract 5

20=2x         -> divide by 2

10=x            ->answer!

Hope that helps!

Answer:

x = 10

Step-by-step explanation:

f(x) equals both 25 and 2x + 5, so set the equations equal to one another and solve for x.

2x + 5 = 25

2x = 20

x = 10

Plug in what you got for x to check if it is right

2(10) + 5 = 25

20 + 5 = 25

25 = 25

Sudha earns ` 189 in a day and Radha earns ` 112 in a day. About how much will each of them earn in 30 days

Answers

Answer:

the sudha and radha earns 5,670 and 3,360 respectively

Step-by-step explanation:

Since in the question it is mentioned that

Sudha earns 189 in a day

And, radha earns 112 in a day

so in 30 days, sudha earns

= 189 × 30 days

= 5,670

And, radha earns

= 112 × 30 days

= 3,360

Therefore the sudha and radha earns 5,670 and 3,360 respectively

Which value for b makes the equation b/4 =12 true?

Answers

48 would be in that place because 12 x 4 would get you to 48, which means that 48 is the answer for this one. Hope this helped. I had to edit the answer out because it glitched, sorry :/

The value for b that makes the equation b/4 = 12 true is b = 48.

We have to find the value for b that makes the equation b/4 = 12 true, we can solve for b by multiplying both sides of the equation by 4.

b is the variable in the equation.

b/4 = 12

Multiply both sides by 4:

4 × (b/4) = 4 × 12

This simplifies to:

b = 48

Therefore, the value for b that makes the equation b/4 = 12 true is b = 48.

Plsss can someone answer I have 2 minutes

Answers

Answer:

x = 2

Step-by-step explanation:

You can make a ratio out of this!

2 / x = (x+1) / 3

1. Cross multiply^

2. 2 * 3 = x (x+1)

3. 6 = x^2 + x

3. x^2 + x - 6

4. Factor^

5. (x-2)(x+3)

6. x - 2 = 0 turns into x = 2

7. x + 3 = 0 turns into x = -3

8. There's not way to measure -3 yet, so you are left with x = 2

A.) 4 red marbles and 6 blue marbles

Step-by-step explanation:

If you times 2 x 2 then you will get 4

If you times 3 x 2 then you will get 6

And since the ratio is red : blue

2 : 3 is equivalent to 4 : 6

Just like  [tex]\frac{2}{3} = \frac{4}{6}[/tex] they are the same thing.

You buy a flight to California for $305.72. The tax is 7.65%. What is the final cost of the ticket?



Show work and use method

Answers

Answer:309.83

Step-by-step explanation:

The final cost of the flight ticket $329.10758.

Given that, the cost of flight ticket is $305.72 and tax=7.65%.

What is the tax?

Taxes are mandatory contributions levied on individuals or corporations by a government entity—whether local, regional, or national. Tax revenues finance government activities, including public works and services such as roads and schools, or programs such as Social Security and Medicare.

Now, tax = 7.65% of 305.72

= 7.65/100 × 305.72

=0.0765 × 305.72

=$23.38758

Total cost = 305.72+23.38758

=$329.10758

Therefore, the final cost of the flight ticket $329.10758.
