Answer:
Second option: 
Step-by-step explanation:
You know that "x" represents the Avery's weigth (in pounds).
Let be "y" the weight of Jada in pounds.
Since Jada weighs 18 pounds more than Avery, you can write this expression:

The weight of them together is:

Substituting, you get:

Therefore, the expression that tells how much the two of them weigh together is the one provided in the second option:

Answer:
Step-by-step explanation:
<u>Cube with side 2 has volume:</u>
<u>Cube with side 6 has volume:</u>
<u>Number of cubes:</u>
The answerer is combining terms in x with constants
that is, 13x + 5 ≠ 18x
13x + 5 + 17x - 4.5 + x
= (13x + 17x + x ) + 5 - 4.5 ← collecting like terms
= 31x + 0.5 ← correct simplification

55= 1, 5, 11 and 55
3= 1,3
66= 1, 2, 3, 6, 11, 22, 33, 66
Step-by-step explanation:
you just need to find the multiplacation to eah number
Answer:
First set: 0.95. Second set: 0.86. Third set: 0.88.
Step-by-step explanation:
Imagine that these are not decimals, they are regular numbers (for example: 0.88 is turned into 88). You would determine which one is the greatest depending on which one is higher (like 44 is higher than 32). Therefor the first set: 0.95 the second set: 0.86 the third set: 0.88.
