They have the same number of valence electrons which, in general, gives them similar oxidation numbers and other similar chemical and physical properties. The similarities are most pronounced in the groups at either side of the standard periodic table, and are least pronounced for the transition and rare earth elements.

(A) Bella's TV ratio of sides: 36"/27" = 1.333...

Lenny's: 52"/29.25" = 1.777...

Bella's and Lenny's TVs are NOT similar - their side ratios are different. Bella's is 4:3 while Lenny's is close to 16:9.

(B) Bella's TV has an exact ratio of 4:3 (36/27=4/3) and so is the older type.

Lenny's TV has a ratio of 52"/29.25". Divide both 52 and 29.25 by 3.25 to get 16/9, or 16:9. So Lenny's is the newer type.

Graph linear system and estimate the solution y=5x + 2 y=3x
NeTakaya
Y = 5x + 2
y = 3x

  5x + 2 = 3x
- 5x        - 5x
          2 = -2x
         -2    - 2
         -1 = x
y = 3x
y = 3(-1)
y = -3
(x, y) = (-1, -3)

What is the answer to this problem 1.5(x + 4) – 3 = 4.5(x – 2)?
erastova [34]

Answer:

x = 4

Step-by-step explanation:

1.5(x + 4) – 3 = 4.5(x – 2)

Distributive property

1.5x + 6 - 3 = 4.5x - 9

1.5x + 3 = 4.5x - 9

1.5x - 4.5x = -9 -3

-3x = -12

  x = 4
