The value of x in the equation, 3x + 2 = 5 is 1.

In order to solve this equation: 3x + 2 = 5, take the following steps:

Combine similar terms together:

3x = 5 - 2

Add the similar terms together

3x = 3

Divide both sides of the equation by 3 in order to make x the subject f the formula

3x / 3 = 3 /3

x = 1

Step-by-step explanation:

f(x) = ³√x -15

y = ³√x - 15

Finding inverse,

x = ³√y - 15

x³ = y -15

y = x³ + 15

f-¹(x) = x³ + 15

Answer:

Step-by-step explanation:

All we need to do is substitute the y and x. This would then look like:

9y + x =

9 × 7 + x =

9 × 7 + 5.

Answer:

a. 3.4m

b. 12.2m

Step-by-step explanation:

SOH CAH TOA

[tex]Sin QPS=\frac{Opposite}{hypotenuse}[/tex]

sin 15° = [tex]\frac{QS}{PQ}[/tex]

QS= sin 15° * PQ

QS = 0.2588 * 12.6 = 3.36088 ≈ 3.4m

a. The length of QS = 3.4m

b. [tex]cos QPS=\frac{Adjacent}{Hypotenuse}[/tex]

Cos 15° = [tex]\frac{PS}{PQ}[/tex]

PS = Cos 15° * PQ

PS = O.9659 * 12.6 = 12. 17034 ≈ 12.2m

The length of PS = 12.2m

Answer:

Step-by-step explanation:

0056 because 1% is 72 so you know it’s going to have to be less then 72. So to get your percent you divide 40 by 7200 so 40/7200. This will get you .00555556 which I rounded to .0056

Answer: 10 minutes

Step-by-step explanation:

Let x be minutes.

Toatl costs for a call are:

A:  35 + 3x

B:  45 + 2x

When will A = B?

35 + 3x = 45 + 2x

1x = 10

They are equal cost at 10 minutes

Answer:

14x+3=8x+3

14x+3 -3 = 8x+3 -3

Cancels out the 3

14x = 8x

14x - 8x = 8x -8x

Cancels out the 8x

14x = 0

x = 0

Step-by-step explanation:

Andre should have collected the like terms in order to have all the variables x on one side before taking the difference.

Given the inequality expression solved by andre expressed as:

14x + 3 ≤ 8x + 3

Simplify to have:

14x - 8x ≤ 3-3

6x ≤ 0

x ≤ 0

Hence andre should have collected the like terms in order to have all the variables x on one side before taking the difference.

Answer:

I think it is $91.89.

Step-by-step explanation:

1. Take the number and add sales tax by multiplying 0.0725 ( since that is what the percentage is in a decimal form). Then add that to the original and you have what it would be plus sales tax: $60.05.

2. Then you would need to multiply by 0.18. You would get 10.809

3. Next, subtract the 10.809 from $60.05 and the answer is $49.24.

Step-by-step explanation:

c = cost

t = sale tax %       5.125% = .05125 as a decimal.  

c  = c + ( c × t %)  or c = c + (c × .05125 )

Answer:

cost of admission for each child was $4.00, and each adult was $25.33

Step-by-step explanation:

When solving questions like these , I like to break down the problem so I understand it better.

Let x ---> cost of the admission for each child

Y ---------> cost of the admission for each adult

9x+3y = 112 ---> equation A

8x + 3y = 108 ---> equation B

Subtract B from A

9x+3y=112

-8x+3y = 108

x = 112-108

x = 4

Find value of y by substituting value of x into equation

9(4)+3y=112

Solve for y

36+3y = 112

3y = 112=36

3y = 76

y = 25.33
