Answer:
7x² - 3x - 4
Step-by-step explanation:
<u>Step 1: Write expression</u>
(6x² - x + 3) + (-2x + x² - 7)
<u>Step 2: Combine like terms (x²)</u>
7x² - x + 3 - 2x - 7
<u>Step 3: Combine like terms (x)</u>
7x² - 3x + 3 - 7
<u>Step 4: Combine like terms (constants)</u>
7x² - 3x - 4
Answer:
a) How many minutes does it take to make one balloon sculpture?
= 4 minutes
b) How many balloons are used in one sculpture?
= 6 balloons
Step-by-step explanation:
In 88 minutes, he uses 132 balloons to make 22 identical balloon sculptures.
a) How many minutes does it take to make one balloon sculpture?
22 identical balloon sculptures = 88 minutes
1 balloon sculpture = x
x = 88 minutes/22
x = 4 minutes
b) How many balloons are used in one sculpture?
22 balloon sculptures = 132 balloons
1 balloon sculpture = x
Cross Multiply =
22x = 132 balloons
x = 132 balloons/22
x = 6 balloons
Exact form: 3/2
decimal form:1.5
mixed number: 1 1/2
