Answer:I think your Answer would be x=14 but I am not sure.
Step-by-step explanation:
2log 10 (x+86)=4
Determine the defined
2log 10 (x+86)=4,x >-86
Divide both sides by 2
log 10 (x+86)=2
Solve by converting the logarithm into exponential form
x+86=10 2
Evaluate the power
x+86=100
Move constant to the right
x=100-86
Subtract the numbers
x=14,x>-86
Check if the solution is in the defined range
SOLUTION
X=14
Answer:
4.32 is 12% of 36
Step-by-step explanation:
You would write the 80.5 on the outside 418.6 on the inside. You can't divide by a decimal so you have to move the decimal point as many times as you need to on the outside number. You only have to move it over once in the80.5 so it is now 805. You do the same thing to the inside so it it is 4186. You are now dividing 4186 by 805. The answer is 5.2
Answer:
Step-by-step explanation:
16. 180=8x+2x
x=10°
17a. 180=(180-126)+2x+(180-6x)
x=14°
17b. 180=4x+x+65
x=23°
If I am correct it should be the second one
