Answer:
=7
Step-by-step explanation:
sum of all no÷total no
=1+2+3+4+5+6+7+8+9+10+11+12+13 ÷ 13
=91 ÷ 13
=7
If you’re solving for y it’s 7/10
Answer:
D
Step-by-step explanation:
so total travel by x bikers = 50 multiplied by x = 50x
According to the question
50x = 560
dividing 560 miles by 50 miles per biker give ya 11.2 or approximately 12 bikers.
Answer:
The integers are 11 and 12
Step-by-step explanation:
11 and 12 are consecutive positive integers, and 11 x 12 = 132.
Let x = number of long sleeve shirts
Let y = number of short sleeve shirts
x + y = 200
x/2 + y/3 = 80
Now solve this pair of simultaneous equations to find x and y.
