As the first step, you have to distribute
2x - 12 + 4x + 16 = 40 Now combine the like items
6x + 4 = 40
6x = 36
x = 6
Answer:
B 236in³
Step-by-step explanation:
you use the equation
V=πr²h/3
π=PI r=Radius h=height
Sense in this problem they give you diameter instead of radius you want to divide it by 2 to get one half.
so the equation used looks like this:
3.14•5²•9/3=235.5
rounded up is 236in³

Explanation:</h2>
Here we have to solve a system of linear equations in three variables. Let:
x: Cost of pens
y: Cost of pencils
We know that:
- Bailey buys 2 pens and 6 pencils and spends a total of $7.00. So:
- Jeremiah buys 3 pens and 5 pencils and spends a total of $7.50. So:
Multiplying eq1 by 3 and eq 2 by -2:
Then adding these two resultant equations:
How much will Maggie spend to purchase 4 pens?
Each pen costs $1.24, so 4 pens will cost:
Answer:
The solution is that P > 5
Step-by-step explanation:
To solve the equation, start by following the order of operations in order to isolate the term P.
2(P + 1) > 7 + P
2P + 2 > 7 + P
P + 2 > 7
P > 5
