Answer: The answer is 904.32
We will need to have two equations here, having x as the missing length. We know that the chairs are in the same amount on each occasion, so each equation should be equal to the other.
This sets up a problem of:
6x + 7 = 4x + 13
7 and 13 being the leftover chairs and 6 and 4 being the rows. Let’s solve for x.
x = 3
Knowing this, we plug in x for one of the equations
6(3) + 7
18 + 7
25
Liam has 25 chairs.
1km = 1000m
1hr = 3600sec
Do proportions:
1km / 1000m = 15km / x
15000m = x
1hr = 3600sec
15000/3600 = 4.2m per second
Choice 4
Step-by-step explanation:
AB · BE = CB · BD Given
CB/BE = AB/BD Division Property of Equality
<ABC = <DBE Vertical angles are equal
ΔABC ≅ ΔDBE SAS Similarity Theorem

Answer:
5 seconds
Step-by-step explanation:
<em>First let's use the equation.</em>
D (Distance) = Speed (s) x Time (t)
<em>Now let's find the components given in the problem.</em>
Distance = 10 meters
Speed = 2 m/s
<em>Now let's substitute the values in.</em>
10 = 2t
<em>Now let's solve for t.</em>
10 = 2t
t = 
t = 5
Therefore, it will take 5 seconds.
