The first thing you would need to know is PEMDAS. Also stands for parenthesis, exponents, multiplication, division, addition and subtraction.
This shows the order you should follow when solving problems like these.

This problem states that the first thing that you would look for is parenthesis. There are parenthesis in this statement, but there's a number before the parenthesis. In this case, your first step would be to take -4(3) - -4(-5x)
The first step is using distributive property to -4(3-5x) to get
-4(3) - (-4)-5x

Today, everything at a store is on sale. The store offers a 20% discount. Write an equation for this situation in terms of y.

SpyIntel [72]

The discount price will be 0.8X dollars.

Step-by-step explanation:

Given,

Price of an item = X dollars

Discount = 20%

Amount of discount = 20% of Price of item

Amount of discount =

Price of item after discount = Price of item - Amount of discount

Price of item after discount = X-0.2X = 0.8X dollars

The discount price will be 0.8X dollars.

After two plays the wildcats gained a total of 16 yards. If X represents the number of yards for play one, and Y represents the

Taya2010 [7]

The equation for this problem would be:
x+y = 16
Rearranging the equation, it can be expressed as:
y = 16 - x

To obtain ordered pairs, replace random values of x up to 16 to find the value of y. The ordered pairs are tabulated and the graph is shown in the attached picture.

A semicircular archway is built in front of a garden using 8 congruent granite tiles, as shown in the diagram. Find the area of

crimeas [40]

So there's 8 tiles.
Radius from archway to the outer edge would be : 7 +1 = 8ft

You can use this formula to count the area of semi circle : π r^2/2

A = 3.14 x 8ft^2 = 100.48 ft ^2
A = 3.14 x 7ft^2= 76.92 ft^2

100.48 - 76.92 = 23.55 ft^2

Then you have to divide it with the total tiles
23.55/8 = 2.94 ft^2 per tile >> (rounded to nearest tenth)

hope this helps
