X=7/12
Alright so let's solve this! :)
••• Subtract 3w from both sides.
<span><span><span><span>5w</span>+3</span>−<span>3w</span></span>=<span><span><span>3w</span>+10</span>−<span>3w</span></span></span><span><span><span>2w</span>+3</span>=10
</span>••• Subtract 3 from both sides.
<span><span><span><span>2w</span>+3</span>−3</span>=<span>10−3</span></span><span><span>2w</span>=7
</span>••• Divide both sides by 2.
<span>2w/2</span>=<span>7/<span>2
</span></span>=<span>7/2
and then 7/2=3.5</span>
Multiply all numbers together
There were 100 total students surveyed.
There are 41 freshman students that have an ATM card.
The probability is the number of freshman that have an ATM card over the total number of students.
The probability becomes 41/100
Now divide the fraction to get the decimal answer:
41/100 = 0.410
Answer:
Step-by-step explanation:
Q1
- 6 + ∛3x² = 18
- ∛3x² = 12
- 3x² = 12³
- 3x² = 1728
- x² = 1728/3
- x² = 576
- x = √576
- x = ±24
Option D
Q2
- ∛3x² - 5 = 10
- ∛3x² = 15
- 3x² = 15³
- 3x² = 3375
- x² = 1125
- x = √1125
- x = ± 15√5
Option A
Q3
- 3∛x² - 2 = 7
- 3∛x² = 9
- ∛x² = 3
- x² = 3³
- x² = 27
- x = √27
- x = ±3√3
Option C
Q4
- ∛4x² + 2 = 9
- ∛4x² = 7
- 4x² = 7³
- 4x² = 243
- x² = 243/4
- x = √243/4
- x = ± 7√7/2
Option D
