Answer:
x = 1.5
Step-by-step explanation:
We need a value of x that would result in 2x+9 = 12
2x+9 = 12
2x = 12 - 9
2x = 3
x = 3/2 or 1.5
====
CHECK
Does 2x+9 = 12 when x = 1.5?
2x+9 = 12
2(1.5)+9 = 12
3 + 9 = 12 YES
I'm going to say for this one it's going to be 46% Notice that the word percent has the word "cent", meaning a hundred. So "per hundred". We have 46 out of 100 here, so 46/100, and we can simplify to 23/50. Hope this helps.

Answer: No solution
<u>Step-by-step explanation:</u>
1st number: x
2nd number: x + 2
- reciprocal of the larger is

- 4 times the reciprocal of the smaller is 4

- reciprocal of the larger of two consecutive even integers is subtracted from 4 times the reciprocal of the smaller is 4
- 
- the result is 56: 4
-
= 56
Solve the equation:
4
-
= 56
-
= 56(x(x + 2))
4x + 8 - x = 56x² + 112x
3x + 8 = 56x² + 112x
0 = 56x² + 109x - 8
Use the quadratic formula to solve:
x = 
The result is NOT AN INTEGER so there is NO SOLUTION
Answer:
its D 103°
Step-by-step explanation:
Sum of a pentagon=540
117+100+115+105+x=540
437+x=540
x=540-437
x=103°
