Ten members of the academic team went to a local restaurant after their contest. Each meal combo that came with soda cost $6.75,

Aneli [31]

Answer:

7 ordered with Soda;

3 ordered with water

Step-by-step explanation:

Given

$m \to$ With water

$n \to$ With Soda

So:

$m + n =10$ --- total

$5m + 6.75n = 62.25$ -- cost

Required

Find m and n

$m + n =10$

Make m the subject

$m = 10 - n$

Substitute $m = 10 - n$ in $5m + 6.75n = 62.25$

$5(10-n) +6.75n = 62.25$

$50-5n +6.75n = 62.25$

Collect like terms

$-5n +6.75n = 62.25 - 50$

$-5n +6.75n = 12.25$

$1.75n = 12.25$

Solve for n

$n = 12.25/1.75$

$n = 7$

$m = 10 - n$

$m = 10 - 7$

$m =3$

Please help I'll give the brainiest to the right answer!

Anna [14]

Answer:

$x=1$

Step-by-step explanation:

Because vertical angles are always equal, we want to solve $50x+10=70x-10$ .

We can add 10 to both sides to get $50x+20=70x$ .

We can subtract $50x$ from both sides to get $20=20x$ .

Lastly, we divide both sides by 20 to get $1=x$ .

So, $\boxed{x=1}$ and we're done!

The check is left as an exercise to the reader.
