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

- Solving quadratics
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
4x² + 3 = 4x + 2
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Equality Property] Rewrite in standard form: 4x² - 4x + 1 = 0
- Factor: (2x - 1)² = 0
- Solve: x = 1/2
Answer:
30 x 24 = 720
720 / 2 = 360
<u>360 inches squared</u>
Answer:
10 students/van
48 students/bus
Step-by-step explanation:
(a) 13v+5b = 370
(b) 12v+10b = 600
(a) - (b)
v -5b = -230
v = 5b-230
12(5b-230) + 10b = 600
60b+10b -2760=600
70b=3360
7b=336
b=48
v = 5(48) - 230 = 10
v = 10
Let's check
12(10) +10(48) = 600
