Answer:
x≤3
Step-by-step explanation:
2(4+2x)≥5x+5
1) Distribute 2 to 4 and 2x:
8+4x≥5x+5
2) Subtract 4x from both sides:
8≥x+5
3) Subtract 5 from both sides:
3≥x
4) Rewrite with variable first:
x≤3
Answer:
Step-by-step explanation: s = small room = 2
l = large room = 4
12s + 11l = 28 + 22 = 50
as I said before s = 2 and l = 4
s*s + l*l = 2*2 + 4*4 = 4 + 16 = 20
Answer:
the sides the formula for that is 2(pi)radius(height). the formula for the total surface area is 2(pi)radius(height) + 2(pi)radius squared.

Answer: Yes</h3>
========================================================
Explanation
The ratio 8:10 simplifies to 4:5 when you divide both parts by 2.
The ratio 16:20 simplifies to 4:5 when you divide both parts by 4
Therefore the two ratios 8:10 and 16:20 are both equal 4:5, so they are equal to one another.
------------
Put another way,
(8 large)/(10 small) = (16 large)/(20 small)
8/10 = 16/20
8*20 = 10*16 ... cross multiply
160 = 160
We get a true equation, so the first equation is true as well.
This shows the ratios are equivalent.
-------------
Or you could have...
(8 large)/(16 large) = (10 small)/(20 small)
8/16 = 10/20
8*20 = 16*10
160 = 160
We get the same conclusion as before.
