If the current ratio of red to blue to green socks is 2:3:7, then t<span>here are exactly 2x red socks, 3x blue socks and 7x green socks.
</span>
1. If amount of red socks are increased by n new socks, then t<span>here are exactly 2x+n red socks, 3x blue socks and 7x green socks and (2x+n):3x:7x=8:9:21. This means that 2x+n=8y, 3x=9y, 7x=21y. You have that x=3y and 6y+n=8y, n=2y.
</span>
2. If amount of blue socks are increased by n+2 new socks, then t<span>here are exactly 2x red socks, 3x+n+2 blue socks and 7x green socks and 2x:(3x+n+2):7x=2:4:7. This means that 2x=2t, 3x+n+2=4t, 7x=7t. Now you have that x=t and 3t+n+2=4t, n=t-2.
</span><span>
</span><span>3. Solve x=3y, n=2y, x=t, n=t-2. You obtain that t=3y, t-2=2y. Then 3y-2=2y and y=2. Hence, x=6=t, n=6-2=4.

(x,y)
P = 50x + 80y
P=(0,5)
=50(0) + 80(5)
= 0 + 400
= 400
P=(1,12)
= 50(1) + 80(12)
= 50 + 960
= 1010
P=(4,10)
= 50(4) + 80(10)
= 2000 + 800
= 2800
Answer:
5 units
Since they both have the same y value, just subtract the a value's x from the b's x value
Answer:
20-foot flag
Step-by-step explanation:
12-foot flag casts 4.8-foot shadow,
which also means that:
4.8-foot shadow is casted by a 12-foot flag
Lets start by find the length of the flag that will cast a 1-foot shadow.
4.8-foot shadow -----> 12-foot flag
1-foot shadow -----> 12 ÷ 4.8 = 2.5-foot flag
Now we can find the flag that will cast a 8-foot shadow.
1-foot shadow -----> 2.5-foot flag
8-foot shadow -----> 8 x 2.5-foot = 20-foot flag
