Answer:
Step-by-step explanation:
Between 9:00 am and 10:45 am, there have been 1 hour and 45 minutes or 1.75 hours have passed. Let x be the speed of the slower cyclist and x+ 5 be the rate of the second cyclist. The given situation is best represented through the equation below,
x(1.75) + (x + 5)(1.75) = 47.25 km
The value of x from the equation is 11. Thus, the two bicyclists' rates are 11 km/h and 16 km/h.
Answer:
19.80
Step-by-step explanation:
use the is/of x %/100 method.
33/100 x x/60
1980/100x = 19.80$
°°° Let's see -
Solve for x - BUT, before we do that, I want to look at the right side of the equal sign: I believe the 'x' on the right side '2 x 3 + 2 x 6' is actually a multiplication sign, so we'll replace that with a proper x so that we don't get confused.
°°° Rewrite the equation -
3 (x) + 10 = 2 × 3 + 2 × 6
°°° Simplify both sides of the equation -
3x + 10 = (2) (3) + (2) (6)
°°° Simplify again (Yes, again) -
3x + 10 = 6 + 12
3x + 10 = (6 + 12) (Combine Like Terms)
3x + 10 = 18
°°° Subtract 10 from both sides -
3x + 10 - 10 = 18 - 10
3x = 8
°°° Divide both sides by 3 -
3x / 3 = 8 / 3
x = 8 / 3
°°°FINAL ANSWER°°° -
x = 8 / 3
