Answer:
x = -14
Step-by-step explanation:
The expression to write in this problem is:
"the sum of x and 12 equals the sum of half of x and 5"
We have:
- The sum of x and 12 is: 
- The sum of half of x and 5 is: 
So, the equation to write in this problem is
We solve it as follows:
1) First, we subtract 
from both sides, and we get
2) Then, we subtract 12 from both sides:
3) Now we multiply both sides by 2:
So, this is the solution.
The sum of the two sides of the triangle must be greater than the third side, so
5<x<41 is the answer
Answer:
113.04
Step-by-step explanation:
formula for area is
pi times radius times radius
if the radius is 6,
do 6 times 6=36
36 times 3.14=113.04
Answer:
Step-by-step explanation:
<u>Let the cost of daylilies = d and ivy = i, then we have below equations:</u>
- d + 12i = 114
- 10d + 10i = 150
<u>Simplify the second equation:</u>
<u>Subtract the second equation from the first:</u>
- d - d + 12i - i = 114 - 15
- 11i = 99
- i = 9, ivy costs $9
<u>Now find d:</u>
- d = 15 - 9 = 6, daylilies cost $6
