Expanding brackets is just your book's way of saying to use the distributive property and then simplify to solve each equation.
I'll show the work for a and b and then the answers for the rest.
a.
4(g + 5) - 4g
Multiply each part inside the parentheses by 4
4g + 4(5) - 4g
4g + 20 - 4g
Now combine like terms to simplify the equation. In this case, the 4g and - 4g cancel each other out.
4g - 4g + 20
0 + 20
20
20 is your answer.
b.
6(p + 4) + 2(p - 12)
Multiply each part of the first set of parentheses by 6 and the second set by 2
6p + 6(4) + 2p + 2(- 12)
6p + 24 + 2p - 24
Combine like terms
6p + 2p + 24 - 24
8p + 0
8p
8p is your answer
c. 6z
d. 3a + 8
e. 8a + 16 which simplifies 8(a + 2)
f. 32w + 16 which simplifies 16(2w + 1)
Answer:
i believe your answer would be 21,765
Step-by-step explanation:
since there are 1000 grams in a kilogram the equation would be 4353÷.200
<span>The correct answer is B. False. Every individual person perceives emotions differently and reacts to them differently meaning that there is no objective way to determine their strength. That's why crying is not a measure for sadness nor is laughing a measure for happiness and both can easily be simulated, or a person can be extremely sad yet not cry at all.</span>
I got 3.33 because I just set the problem up as
4x+5=x+15
and then I did
4x-x=3x
and then I did
15=3x+5
and then
15-5=10
and then
3x=10
then
10÷3=3.33
