Solve for x: −34x−1=115 .

krek1111 [17]

Answer:

x = - $\frac{64}{45}$

Step-by-step explanation:

- $\frac{3}{4}$ x - 1 = $\frac{1}{15}$

add 1 to both sides:

- $\frac{3}{4}$ x = $\frac{16}{15}$

multiply both sides by 4:

-3x = $\frac{64}{15}$

divide both sides by -3:

x = - $\frac{64}{45}$

In a certain card game, for every 4 blue cards, there are 3 yellow cards. There are a total of 84 blue and yellow cards in the g

IRINA_888 [86]

Answer:

Step-by-step explanation:

Ratio: Blue:yellow=4:3

$4:3=7\\?:?=84\\84/7=12\\$

4x12=48

So basically, You make a "equation".

You add 4 and 3 which is 7.

So since you know there is 84 total cards. That will equal the "?". So you divide the 84 and 7 since that will show what you will multiply with 4 and 3 to keep the blue and cards equally balanced. So you multiply the 12 and 4. Which is 48.

So there are 48 blue cards. Hope this helped you C:
