Hello from MrBillDoesMath!

Answer:

a = 15



Discussion:

Division precedes subtraction ( order of operations) so


a/3-1 =4                              =>   is equivalent to

(a/3) - 1 = 4                         =>   add 1 to both sides

(a/3) - 1 + 1 = 4 + 1 = 5       =>   multiply both sides by 3

(a/3)* 3  = 5*3 = 15            =>

a = 15

Thank you,

MrB

Hey can you please help me posted picture of question

The correct answer is the las option (Option D), which is:

 D. f(x)=(x+4)^4

 The explanation is shown below:

 1. The initial function was G(x)=x^4, whose graph shows that the shape has its vertex at 0,0.
 
 2. If the it was shift 4 units to the left, you only has to add a 4 to the function.

 3. Therefore, you obtain the the equation of the final shape is:

 f(x)=(x+4)^4

 As you can see, the answer is the option D.

Can someone please help me with number 13.

You can set up 2 equations for the two companies that sell pizza. Pizza A's will be:
y = 1.5x+10

And B's will be:
y = x+12.50

To find the number of toppings we will need to make the companies prices equal can be found by setting the equations equal to each other and solving for x, because x is the price per topping. So:
1.5x+10 = x+12.50
1.5x = x+2.50
0.5x = 2.50
x  =   \frac{2.5}{0.5}  = 5

So, the number of toppings you will need is 5 toppings to make their prices equal. 

*If any step is unclear, then hmu!

Area is length times width in this scenario. The length is going to increase by 3; this can be expressed by the term L+3. The width is 5, but the total area is going to be 90. Your expression should look like this:
5(L+3)=90
First, multiply the 5 on the left side of the equation.
5L+15=90
Subtract 15 from both sides to get the coefficient and the variable by itself.
5L=75
Divide by 5 on both sides to get the variable alone.
L=15
You're not done yet. Remember, you must add 3 back into L to get the new length. The original garden would have been 15 meters in length, but the new length of the new garden will be 18 meters. 
To check this, use the formula for area. 
18(5)=90
90=90
