Susanne is 16 years old.
b = Bob's age
s = Susanne's age
d = Dakota's age
Bob's age is 4 times greater than Susanne's age:
b = 4s
Dakota is three years younger than Susanne:
d = s - 3
The sum of Bob's, Susanne's, and Dakota's ages is 93:
b + s + d = 93
solve these equations:
b = 4s
d = s - 3
b + s + d = 93
and get:
b = 64 years
s = 16 years
(remember that s = Susanne)
d = 13 years
Answer:
0.075 sq km
Step-by-step explanation:
Given that there is a rectangular field with dimensions of length =300 m and width = 250 m.
We have to calculate area of this rectangle in the units of square kilometres.
Let us convert length and width into km
1000m = 1 km
Hence length = 300/1000= 0.3 km and
width = 250/1000 = 0.25 km.
ARea = length x width = 0.3 x 0.25
=0.075 square km.

We know already that desk A and desk B are on the same column, since both coordinates' x factors are 7. So all we need to do now is find the differeance of 2 and -8. So, we get the [very simple] equation 2 - (-8) = d. Now, when you subtract a negative, it's pretty much just adding, so we can simplify this equation to 2 + 8 = d, and we all know 2 + 8 = 10. So the distance between the two desks is 10 units.
Hope this helps! If there is anything wrong feel free to point it out.
Have a nice day!
