Answer:
Easiest way to do this is to get the X's on one side of the equals sign and the Y's on the other. <u><em>Then</em></u>, you can choose the one with the negative sign in it.
When you do that,
First one is 2x=0+y, or y = 2x
Second one is 2y=0+x, or 2y = x (weird right)
Third one is x=0+2y, or 2y = x (again, weird right)
Final one is 2y=0-x, or 2y = -x
The final one is the answer. Cheers, but don't forget to remember this for next time bro.
Answer:
x ≤ 63
Step-by-step explanation:
x/3-10 ≤ 11
Opposite of -10 is addition, 10+11= 21
Opposite of x/3 is multiplication 3, 21*3= 63
Answer:
27 : 8
Step-by-step explanation:
Given 2 similar figures with ratio of sides a : b, then
ratio of areas = a² : b² and
ratio of volumes = a³ : b³
Here the ratio of areas = 9 : 4, thus
ratio of sides = : = 3 : 2
ratio of volumes = 3³ : 2³ = 27 : 8
