Solve 3 + (4 + 2) ÷ 2 x 3 - 52
| 4 | |
| \(\frac{5}{8}\) | |
| 3\(\frac{1}{2}\) | |
| -13 |
Use PEMDAS (Parentheses, Exponents, Multipy/Divide, Add/Subtract):
3 + (4 + 2) ÷ 2 x 3 - 52
P: 3 + (6) ÷ 2 x 3 - 52
E: 3 + 6 ÷ 2 x 3 - 25
MD: 3 + \( \frac{6}{2} \) x 3 - 25
MD: 3 + \( \frac{18}{2} \) - 25
AS: \( \frac{6}{2} \) + \( \frac{18}{2} \) - 25
AS: \( \frac{24}{2} \) - 25
AS: \( \frac{24 - 50}{2} \)
\( \frac{-26}{2} \)
-13
What is the next number in this sequence: 1, 9, 17, 25, 33, __________ ?
| 41 | |
| 37 | |
| 50 | |
| 46 |
The equation for this sequence is:
an = an-1 + 8
where n is the term's order in the sequence, an is the value of the term, and an-1 is the value of the term before an. This makes the next number:
a6 = a5 + 8
a6 = 33 + 8
a6 = 41
Which of the following is not an integer?

An integer is any whole number, including zero. An integer can be either positive or negative. Examples include -77, -1, 0, 55, 119.
How many 9-passenger vans will it take to drive all 39 members of the football team to an away game?
| 6 vans | |
| 4 vans | |
| 5 vans | |
| 3 vans |
Calculate the number of vans needed by dividing the number of people that need transported by the capacity of one van:
vans = \( \frac{39}{9} \) = 4\(\frac{1}{3}\)
So, it will take 4 full vans and one partially full van to transport the entire team making a total of 5 vans.
