Answer:
x= 8
Step-by-step explanation:
Step 1- Distribute into the parenthesis by 1.
4x+2+3(-1)+3(-1)x= 7
Step 2- Simplify.
4x+2-3-3x= 7
Step 3- Add common variables.
(4x-3x)+(2-3)
1x-1= 7
Step 4- Add 1 to both sides.
1x-1= 7
+1 +1
1x= 8
Step 5- Divide both sides by 1.
1x= 8
1 1
x= 8

An integer has to be either even or odd
Even numbers are numbers divisible by 2, while odd numbers are not
Let us represent the 2 even numbers like this
ax+1
bx+1
When you add the two numbers together, you get
2a + 1 + 2b + 1
This can be simplified using the inverse of distributive property
2(a+b) + 2
2(a+b+1)
This is the sum, which is divisible by 2
Answer:
5,20,80,320
Step-by-step explanation:
a1 = 5
an = 4 an-1
Let n = 2
a2 = 4 * a1 = 4*5 = 20
Let n = 3
a3 = 4 * a2 = 4*20 = 80
Let n = 4
a4 = 4 * a3 = 4*80 = 320
Answer:
A. to make inferences about a sampling technique
Step-by-step explanation:
Let x be number of T-Shirts made.
Therefore,
Revenues from the sell = 12*x = 12x
The cost making them = 20+(8*x) = 20+8x
Profits = 12x-(20+8x) = 12x -20-8x = 4x - 20
Now, this profit should be atleast $100. Then,
100<4x-20 => 100+20<4x => 120<4x => 120/4<x => x>30
Therefore, more than 30 T-shirts should be made in order to make atlease $100 profit.
