Sierra is going on a field trip that costs $48. The cost includes $20 for transportation and two tickets that each cost the same

True [87]

We know that there are two tickets (which we'll represent with x) and a fee for transporation (which is $20)

So we can set up the equation 20+2x=48

We want to isolate x so we'll subtract 20 from each side, which gives us the equation
2x=28

Then divide each side by 2
Giving us the final answer of

x=14

So each ticket costs $14

The inverse of this equation

In-s [12.5K]

Answer:

${f}^{ - 1}(x) = \frac{x + 11}{ - 5}$

Step-by-step explanation:

$f(x) = - 5x - 11 \\ - 5x - 11 =x \\ - 5x = x + 11 \\ {f}^{ - 1}(x) = \frac{x + 11}{ - 5}$

3/7 of 8th graders play sports. is 3/5 of the 8th graders that play sports are boys, what fraction of the 8th graders are boys

Svetach [21]

Answer:

$\dfrac{9}{35}$ is the fraction of 8th graders who are boys.

Step-by-step explanation:

Let total number of 8th graders = $x$

Given that, $\frac{3}{7}$ of 8th graders play sports

$\Rightarrow$ 8th graders who play sports = $\frac{3}{7} \times x$

Also, Given that, $\frac{3}{5}$ of 8th graders that play sports are boys

Number of 8th graders that play sports, and are boys = $\frac{3}{5} \times \text{Number of 8th graders who play sports}$

$\Rightarrow \dfrac{3}{5} \times \dfrac{3}{7} \times x\\\Rightarrow \dfrac{9}{35} \times x$

Hence, the answer is:

$\dfrac{9}{35}$ is the fraction of 8th graders who are boys.
