Answer:
3.5 m/hr
Step-by-step explanation:
2 + c = 5 -c c = speed of current
2 c = 3 c = current speed = 1.5 m/hr
your speed = 5 - 1.5 (or 2 + 1.5) = 3.5 m/hr
Answer:
1)x is 8.5 y is 1.6 b) y= 7.8 x=6.8
Step-by-step explanation:
1) you have to times 3.4 by 2.5 because if you ties 2 b 2.5 is 5. Then you have to do the opposite for y, you have to divide 4 by 2.5.
b) 10.8 / 2 is 5.4 so 15.6/2 is 7.8. 3.4 * 2 is 6.8
I think its this.

S + 2.8 = 6.59
s = ?
To solve for s use the inverse operation of addition, which is subtraction.
s + 2.8 = 6.59
6.59 - 2.8 = s
6.59 - 2.8 = 3.79
s = 3.79
Check:
s + 2.8 = 6.59
s = 3.79
3.79 + 2.8 = ?
3.79 + 2.8 = 6.59
Correct!
This proves: s = 3.79 ;)
Answer:
A) 8
Step-by-step explanation:
The average of two numbers is 7.
6 and x have an average of 7.
sum of terms / number of terms = average
(6 + x)/2 = 7
6+x = 14
x = 8
The number is 8.
