Answer:

7 buses are needed.

Step-by-step explanation:

There are 325 students and adults.

Each bus holds 48 people.

The number of buses needed = $\frac{325}{48}$ = 6.770833333

Since we cant have 0.770833333 buses, we accept that only 7 buses are needed here and that;

325 - (48 × 6) = 37 people will not fill the last bus.

So to solve for the value of a variable in an equation, you would need to isolate x on one side. The first thing you have to do is multiply 2 and (x + 7) together, which can be rewritten as 2(x) + 2(7). After multiplying, your equation would be: $2x+14+3x=12$ , or A.

So the rule with multiplying exponents with the same base is to add the exponents together, and the rule with dividing exponents with the same base is to subtract the exponents. Your equation will be simplified as such:

$4^{(3+4)-9}\\ 4^{7-9}\\ 4^{-2}$

Now the rule with converting negative exponents into fractions is $x^{-m}=\frac{1}{x^m}$ . In this case, 4^-2 would turn into $\frac{1}{4^2}$ , or C, which is your final answer.
