The total hours Suzette biked was 2.5 hours and she ran for 1.5 hours
Let x = total hours Suzette ran.
Let y = total hours Suzette biked
The equation to solve the question will be:
x + y = 4 ....... equation i
6.5x + 14y = 44.75 ........ equation ii
From equation i, x = 4 - y ....... iii
Put the value of x into equation ii
6.5x + 14y = 44.75
6.5(4 - y) + 14y = 44.75
26 - 6.5y + 14y = 44.75
Collect like terms
-6.5y + 14y = 44.75 - 26
7.5y = 18.75
Divide through by 7.5
7.5y/7.5 = 18.75/7.5
y = 2.5
Since x + y = 4
x + 2.5 = 4
x = 4 - 2.5
x = 1.5
Suzette ran for 1.5 hours
In conclusion, the total hours Suzette biked was 2.5 hours and she ran for 1.5 hours.

2/10 chance
4.
0/12 chance or maybe 0/10
Step-by-step explanation:
1.1/5 chance for the number and 1/2 chance for the heads/tails so
2.2/5 chance of getting it to land on an even number + 1/2 for heads
3..2/5 chance of getting it to land on an even number and 1/2 for tails
4.you cant land a 6
2x+4x+9x=180 15x=180 180/15=12 substitute x for 12 to find the angles
