100 miles/4 hours = 25 miles per hour
The last one 7(30)-7(7) because if you do it then it is 7(23) which doesn’t make sense because it is 27 we need to find
Answer:
56/125
Step-by-step explanation:
Answer:
The approximate area is 35 square centimeters
Step-by-step explanation:
we know that
The cross section passing through the diagonal of opposite faces of the cube is a rectangle
so
the approximate area is equal to

where
b is the diagonal of a face
h is the length side of the cube
we have

substitute

I don't know what you mean by property. Do you mean like, commutative, distributive, etc?
but, if this is what you mean:
to solve this:
The operation here is subtraction. Do the inverse. So, add 6 to both sides of the equation
10 + 6 = 16
1/2x - 6 + 6 = 1/2x. (the 6 cancels out)
1/2x = 16
Now, I'm going to assume 1/2 is supposed to be a fraction (not division). So, 1/2 is right next to x which represents multiplication, so do the opposite which is division.
16 divided by 1/2 = 32
1/2x divided by 1/2 = x
x = 32.
