Mamont248 [21]

Answer:

The two numbers are 52 and 12.

Step-by-step explanation:

x+y=64

x=16+3y

Now, substitute the second equation into the first one.

16+3y+y=64

16+4y=64

4y=48

y=12

Substitute 12 into one of the equations in order to find x.

x=16+3(12)

x=16+36

x=52

Answer:

$\large\boxed{d_1=\dfrac{2A}{d_2};\ d_2=\dfrac{2A}{d_1}}$

Step-by-step explanation:

$A=\dfrac{1}{2}d_1d_2\qquad\text{multiply both sides by 2}\\\\2A=2\!\!\!\!\diagup\cdot\dfrac{1}{2\!\!\!\!\diagup}d_1d_2\\\\2A=d_1d_2\to d_1d_2=2A$

$\text{For}\ d_1:\\\\d_1d_2=2A\qquad\text{divide both sides by}\ d_2\neq0\\\\d_1=\dfrac{2A}{d_2}\\\\\text{For}\ d_2:\\\\d_1d_2=2A\qquad\text{divide both sides by}\ d_1\neq0\\\\d_2=\dfrac{2A}{d_1}$

Sophia's school took a field trip. a total of 21 vehicles were needed for the trip. some students took the bus, and some student

Liono4ka [1.6K]

Let x be the number of buses, and y the number of cars.
$\left \{ {{x+y=21} \atop {30x+4y=318}} \right.$
We can solve for y in the first equation to get:
$y=21-x$
Now we can replace 21-x in our second equation, and solve for x:
$30x+4(21-x)=318$
$30x+84-4x=318$
$26x=234$
$x= \frac{234}{26}$
$x=9$

We can conclude that 9 buses were needed for the trip.
