Answers:
- x = 4
- AB = 36
- BC = 36
- AC = 36
All three sides are 36 units long.
===========================================================
Explanation:
Triangle ABC is equilateral, so all three sides are the same length.
Pick any two of those sides, set them equal to each other, and solve for x
AB = BC
8x+4 = 11x-8
8x-11x = -8-4
-3x = -12
x = -12/(-3)
x = 4
Use this x value to find each side. We should get the same value (if not, then an error occurred in solving for x).
- AB = 8x+4 = 8*4+4 = 32+4 = 36
- BC = 11x-8 = 11*4-8 = 44-8 = 36
- AC = 9x = 9*4 = 36
We get the same value for the three side lengths, so this confirms we have the correct x value.
Answer:
Step-by-step explanation:
Given as :
The distance cover while running =
= 5 miles
Let The speed for running = 
The distance cover with bike =
= 80 miles
The speed for biking =
= 15 mph + 
Total Time taken = 5 hours
Now Time = 
∴ 5 hour =
+ 
Or, 5 hour =
+ 
Or, 5 hour = 
or, 5 × (
) = 
Or,
-
= 0
or,
= 0
or,
= 0
Or,
= 0
Or,
= 0
Or,
= 0
∴
= 3 , - 5
So, the running speed = 3 mile per hour
And the biking speed = 15 mph + 3 mph = 18 mile per hour
Hence The running speed of Stu is 3 mile per hour . Answer
Answer: it’s b because if you times that by anything it will always be a product I think
Step-by-step explanation:
Unlike credit card purchases, interest charged on cash advances is already incurred even if you pay before the due date.
32% is the annual interest rate
1 month is the term
200 is the principal
32% / 12 months = 2.67% per month
200 * 2.67% = 5.34 monthly interest
200 * 32% = 64 annual interest
64/12 = 5.33 monthly interest
She has to pay $5.34 in interes
