Answer:
16.02
Step-by-step explanation:
the 89% of 18 is 16.02
I don't quite understand the log form you have, but the way to solve logarithms is to convert them to exponents.
log(b) a = c
b^c = a
So....
log(b) x = y
b^y = x
Does that make sense?
Answer:
Step-by-step explanation:
You know that the three angles of a triangle add up to 180°. If one angle is 38° and another angle is 67°, then the third angle must be 180°-38°-67° = 75°.
You have a straight line across the bottom, and three angles meeting in the middle of it. Those three angles add up to 180°. One of them is 75°, another is 50°, so the third angle must be 180°-75°-50° = 55°.
That leaves you with one unknown angle. ? = 180°-40°-55° = 85°
X times 1.28 = 448
X = 448 divide by 1.28
The items below show the complete steps as to how this is being answered.
1. 3x - 4 = 14 >>>> Given
2. 3x - 4 + 4 = 14 + 4 >>>
Step number 2 above is an addition property of equality. Both sides of the equation are added with 4.
3. Simplifying >>>
3x = 18
4. 3x/3 = 18/3 >>>> Division property of equality
5. >>>> Simplifying,
x = 6
Hence, the order of the choices as answers is C, E, B, A, D.
