Bumek [7]

Answer:

All three statements are true

Step-by-step explanation:

A shipping fee of 5% is charged online with every item purchased online

First let's just take each option and calculate them based on this, to see if the answers matched

Keith buys a 40 dollar book

40 x 0.05 = 2

Therefore there will be a two dollar fee on Keith's book

40 + 2 =42

The first statement is true

A chair costs $80

80 x 0.05 = 4

80 + 4 = 84

The second statement is true

George buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

The third statements are true


All three statements are true

What is the solution to 8(2x + 3) = 48?
Tom [10]
You have to start by using the distributive property. So you take the number next to the parentheses which is “8” and you multiply it with “2x”. This gives you “16x”. Then you multiply “8” with “3” and that gives you “24”. You now have the equation “16x + 24 = 48”.
The next step is to subtract “24” with “48”. This leaves you with “24”. Then you now have “16x = 24” as your new equation. The last step is to divide “16x” with “16”, this cancels it out with itself. Then you divide “24” with “16” and you get 1.5. So “X” equals 1.5 or you can convert it into a fraction witch gives you “3/4”.

How to find the area of a polygon
ipn [44]
The rectangle is 7 x 4 so the area is 28 sq cm
The triangle has a base of 4 and a height of 3.
The formula is A = 1/2 * b*h
You have 2 triangles so:
2(1/2)*4*3= 12 sq cm
Add together:
28 + 12= 40 sq cm
