Answer:
x=67
y=36
Step-by-step explanation:
x+y=103
2y=x+5
Let the time = x
Distance = Speed x time
One train is 75x, the other train 85x
Add together to equal total distance:
75x + 85x = 384
Simplify:
160x = 384
Divide both sides by 160:
x = 384 / 160
x = 2.4 hours
Answer:
23
Step-by-step explanation:
Because 23•23=529 so the square root of 529 is 23.
1 and 7 because they have the same angles
There are 13 girls and 4 more students that are boys that made an A grade. Thus there are 13+4=17 students that are either girls or A students.
The probability of choosing a girl or A student is 17/30.
