Answer:
12 + 4x
Step-by-step explanation:
To solve this you would have to use the distributive property.
The problem would basically go like this.
4 (3+x)
(Distribute)
(4x3) (4 x X)
4x3 = 12, 4 x x = 4x
So the answer would be 12 +4x

Answer:
the answer is 9
Step-by-step explanation:
why it 9 Add '2.7' to each side of the equation.
-2.7 + 2.7 + 0.3x = 9 + 2.7
Combine like terms: -2.7 + 2.7 = 0.0
0.0 + 0.3x = 9 + 2.7
0.3x = 9 + 2.7
Combine like terms: 9 + 2.7 = 11.7
0.3x = 11.7
Divide each side by '0.3'.
x = 39
Simplifying
x = 39
Answer:
C - a stack of 15.6 watermelons
Step-by-step explanation:
Lets first go through each option:
<u>"A shopping receipt that totals $4.90"</u>:
This is an appropriate answer since many items sold are not priced at exact dollars (where there are no cents), so having $4.90 as the total cost after shopping is appropriate.
<u>"A soccer game where the average score is 4.7"</u>:
This is also an appropriate result since it is the <em>average</em> score of a soccer game, so finding a decimal is appropriate.
<u>"A stack of 15.6 watermelons"</u>:
This is not an appropriate result since it would be strange to say a 'stack' or group of something that is not a whole number.
<u>"A classroom with 24 students"</u>:
This is an appropriate result since the number of students is a whole number not a decimal.
Hope this helps :)
