x is equal to 0 because 6 is already equal to 6
so there shouldnt be another number unless its 0
0+6=6
First covert the feet to meters.
1 meter = 3.3 feet.
Divide the total number of feet by 3.3 to get total number of meters:
198 / 3.3 = 60 meters per second.
Multiply meters per second by 15 seconds:
60 x 15 = 900 meters in 15 seconds.
Often with regrouping of 2 numbers then counting them once all together
First one: y=-2x+3 is the answer
We know the perimeter is the sum of all sides. So lenght+length+width+width = 2length+2width.
Let's call the width x. If the length is 4m longer, then it's x+4.
We know the perimeter, so we can make an equation:
56=2x+2(x+4)
And solve from there:
56=2x+2x+8
56=4x+8
48=4x
48/4=x
x=12
The width, which is x, is 12 m. And the length, x+4, is 16 m.
You can check this is correct by calculating the perimeter using those values: 12+12+16+16=56.
