FinnZ [79.3K]3 years ago
5 0

Answer:

Step-by-step explanation:

4x+5y=6

x=\frac{6-5y}{4}

6(\frac{6-5y}{4})-7y=-20

9-7.5y-7y=-20

-14.5y=-20

y=\frac{20}{29}

5(\frac{20}{29})+4x=6

x=\frac{37}{58}

6th-grade math, fill out the table! :)
Svetradugi [14.3K]

Answer:

21 wins, table is attached.

Step-by-step explanation:

The ratio of 7 wins to 2 losses is 7:2. A ratio is just saying that every time one value is increased by 7, the other is increased by 2.

So we can fill out the table, in every iteration wins increases by 7 and losses increases by 2.

When we fill this out, we find that when losses is 6, wins is 21, so when you have 2 losses you have 21 wins.

Hope this helped!

the problem now looks like 7/4 / 1/4
you cancel out both 4
this problem simplified looks like 7/1
which is equivalent to 7 if you divide
