For every 1/4 metric ton it takes 1/8 hours
then multipling by 8 to make the hours =1
for every 2 metric tons it take 1 hour
so the quotient is 2 metric tons per 1 hour

sarah spent a total of 10 on oranges and apples at the supet market. if she spent 3 dollars less for oranges than she did on app

beks73 [17]

Let's write 2 equations from the two statements given.

Sarah spent 10 dollars on both oranges and apples

Let the price of oranges be "x" and price of apples be "y", thus we can write:

$x+y=10$

Oranges cost 3 less than apples, thus we can say:

$y-3=x$

We can substitute this into the first equation and solve for y:

$\begin{gathered} x+y=10 \\ y-3+y=10 \\ 2y=10+3 \\ 2y=13 \\ y=\frac{13}{2} \\ y=6.5 \end{gathered}$

Thus, let's solve for x now,

$\begin{gathered} x=y-3 \\ x=6.5-3 \\ x=3.5 \end{gathered}$

We want the price of oranges (x), thus,

Price of Oranges = $3.50

HELP I DONT GET IT!!!For the system below solve using linear combinations method 2a+3b=1 and -2a+b=11

Maksim231197 [3]

Linear combination method just means to add the equations so that one variable with cancel. In this case the a values are already set up so that they will cancel.
2a + 3b = 1
-2a + b = 11
4b = 12
b = 3

now put 3 back into either of the original equations and solve for a.
2a + 3(3) = 1
2a + 9 = 1
2a = -8
a = -4
(-4,3)
