X + y = 1.....multiply by -2
2x - 3y = -30
-----------------
-2x - 2y = -2 (result of multiplying by -2)
2x - 3y = -30
----------------add
-5y = -32
y = -32/-5
y = 32/5 or 6.4 <===
Answer:
20:21
Step-by-step explanation:
Let's first start by converting each ratio so that the number of girls is the same
2:3
4:7
The least common multiple of 3 and 4 is 12 so...
8:12
12:21
We add 8 and 12 to get the number of junior members...
8+12=20
Then we put it in a ratio with the amount of adult members...
20:21
To find the new sides take the original sides and multiply it by the scale factor
12 * 1.5 = 18
10 * 1.5 = 15
14 * 1.5 = 21
So the new sides are 18, 15, 21. And they correspond to the 12, 10, and 14 respectively
The number of games Ben predict Orioles will win this year is 64 games
