280 students have a total of 560 points
There 60 more boys(x+60) complete than girls(x)
2*(x+60)+2*x= 560
number of girl =x =110
girl point =110*2= 220
Let x = total distance he covered
3x/4 by bus
1/2 . x/4 = x/8 by jogging
the remaining distance = x/8 by walking
thus x/8 = 800ft
x = 8 . 800 = 6400ft
Answer:
A
Step-by-step explanation:
1) first there are a few rules we need to know:
a) the sum of any two sides of a triangle is always larger than the 3rd side
b) the difference between any two sides of a triangle is always smaller than the 3rd side;
hence,
3+4=7
4-3=1
triangle 3,4,5 follows all the rules,
triangle 13,2,11:
11+2=13
the sum of any two sides must always be GREATER than the 3rd side-so this is not an option
triangle 10,4,5
5+4=9
9<10
not an option
Answer:

Step-by-step explanation:

Expand:


Add 27 to both sides:


Add 12x to both sides:


Divide both sides by 4:


Answer:
n= 2/3 - 5/6k , ker
Step-by-step explanation:
-2n-5k+8-4n-11=-7
-6n-5k+8-11=-7
-6n=-7+3+5k
-6n=-4+5k
then divide both sides by -6 to get your answer
n= 2/3 - 5/6k , ker
