Step-by-step explanation:
2(2x + 1) = 3(x - 4)
4x+2=3x-12
4x-3x=--12-2
x=14
There is actually 2 ways to solve this, I will show you both.
The first is obvious, solve for x in the first one, and plug it into the 2nd one and get the answer
4x + 7 = 12
4x = 5
x = 
8() + 3
2 * 5 + 3
10 + 3
13
The 2nd option is to manipulate the 4x + 7 to be 8x + 3
4x + 7 = 12
start by moving the 7 over
4x = 5
multiply both sides by 2
8x = 10
and add 3 to both sides
8x + 3 = 13
Answer:
Step-by-step explanation:
Thrice the sum of three fifths and two thirds less one half is expressed as 3(3/5 + 2/3)-1/2
Open the parenthesis
3(3/5) + 3(2/3) - 1/2
= 9/5 + 6/3 - 1/2
Find LCM
= 9(6)+10(6)-15/30
= 54+60-15/30
= 54+45/30
= 99/30
= 3 9/30
= 3 3/10
Hence the number id 3 3/10
Answer:
The first step is Add 6 to both sides
Step-by-step explanation:
we have
Solve for x
That means ----> isolate the variable x
step 1
Adds 6 both sides
step 2
Multiply by 5/2 both sides
therefore
The first step is Add 6 to both sides
Answer:
You have to write this based on yourself. Just answer each question one by one and then you can compare a whole paragraph.
So for each question you have to choose what you believe you are.
Which social class do you belong to; lower, middle, or upper class?
Why? This could be because you're well off or because you don't have that much money, it depends on which class you believe you are.
Who are your peers? Peers refers to people within the same age bracket as you.
In your everyday choices, whom do you tend to take as a reference point? This is basically asking who influences you, for example your mother or your brother, who do you use as your guidance for how you act. The remaining questions are just asking to specify who, your peers or family members, it's just an addition to the main question.
