4x+2y=0 3x-y=-10 solve the system

erik [133]

Divide the first equation by 2:

$\begin{cases}2x+y=0\\3x-y=-10\end{cases}$

Sum the two equations:

$5x = -10$

Divide both sides by 5:

$x=-2$

Substitute this value for x in one of the equation (for example the first) and solve for y:

$-8+2y = 0 \iff 2y=8 \iff y=4$

18 girls and 12 boys on a swim team. what is the percentage of boys?

nekit [7.7K]

Answer:

40%

Step-by-step explanation:

The first step is to add 18 girls + 12 boys, which gives you the total number of people on the swim team, 30.

Next, you divide the 12 boys by the total swim team members, so:

$\frac{12}{30}$ = 0.4

Then, you multiply 0.4 by 100 to get the percentage:

0.4 × 100 = 40

Therefore, the swim team is made up of 40% boys, and 60% girls.
