Answer:
3 3/7 minutes
Step-by-step explanation:
This calculated using the formula:
1/x + 1/y = 1/n
Where
x = Number of minutes it took Ann to walk = 6 minutes
y = Number of minutes it took Alek to walk = 8 minutes
n = Number of minutes it would take An and Alek to reach the starting point at the same time
1/6 + 1/8 = 1/n
Lowest Common Denominator = 24
4 + 3/24 = 1/n
7/24 = 1/n
Cross Multiply
7n = 24
n = 24/7
n = 3 3/7 minutes
It would take them 3 3/7 minutes to reach the starting point at the same time.
So you plug (-3,7) into the equation and solve it, the answer is (-5,1)
1. we know that product (x) so divide it by 2 and then minus some from 1 side and add on to the other side
<span>==> 6(15+x) = 120
==> 15+x = 20
==> x = 5.
Therefore five new workers joined the crew.</span>
No she would only be able to fit 729, because 9^2 equals 81, and 81*9 equals 729.
