Answer:
x=-12
Step-by-step explanation:
2/3x=-8
Multiple both sides by 3/2
x=-24/2
x=-12
<h3>
Answer: 7.4 hours</h3>
==========================================================
Explanation:
Add up the percentage values:
25+20+6+6+6 = 63
This means 63% of the trip was driven by anyone but Dan. That must mean 100-63 = 37% of the trip is how much Dan drove.
Apply this percentage to the 20 hour duration
37% of 20 = 0.37*20 = 7.4 hours represents how long Dan drove.
extra notes:
- 7.4 hours = 7 hours, 24 minutes because 0.4 hours = 0.4*60 = 24 minutes
- 7.4 hours = 7 hrs + 24 min = 7*60+24 = 444 minutes
Answer:
90
Step-by-step explanation:
90/10= 9
90/5= 18
No number larger than 90 would work.
0.0765 = 7.65 x 10^-2
965,000,000,000,000 = 9.65 x 10^14
8.61×10−8 = 0.0000000861
Answer:
The answer to your question is ∠ABE = 46
Step-by-step explanation:
Data
BE is a bisector of ∠ABE
∠ABE = 2x + 20
∠EBC = 4x - 6
∠ABE = ?
Process
1.- Bisector is a line that divides an angle into two equal angles.
So
∠ ABE = ∠EBC
2.- Substitution
2x + 20 = 4x - 6
3.- Solve for x
2x - 4x = -6 - 20
- 2x = -26
x = -26/-2
x = 13
4.- Find the measure of ∠ABE
∠ABE = 2(13) + 20
∠ABE = 26 + 20
∠ABE = 46
