Answer:
5000cm
Step-by-step explanation:
14 + 16 + 20 = 50m
50m x 100cm/m = 5000cm
Answer:
- 12
Step-by-step explanation:
The easy way to set this up is to take the middle number to be x
(x - 1) + x + (x + 1) = - 33
x - 1 + x + x + 1 = - 33
3x = - 33
x = -33/3
x = - 11
the lowest number is going to be x - 1 = -11 -1 = - 12
The middle number = - 11
The largest number = - 11 + 1 = - 10
Answer:
14yd
Step-by-step explanation:
Scale of the model:
1in to 2yd
This suggest that for every 1in on the model, the actual distance is 2yd.
So;
A model 7in wide will actually be:
1in to 2yd
7in will be 7 x 2 = 14yd
Answer:
9 :)
Step-by-step explanation:
Simplify the radical by breaking the radicand up into a product of known factors, assuming positive real numbers.
Step-by-step explanation:
it is a linear function, if the change in y is constant in relation to the changes of x.
in other words, if the slope y change/x change is the same for every point.
when we look at the table, we see x changes constantly by +2.
and y changes constantly by -6.
so, the change rate/slope is constantly -6/2 = -3.
and therefore it is a linear function.
the equation looks like (the slope is always the factor of x)
y = -3x + b
b we get by using one of the x,y pairs like 1,4
4 = -3×1 + b = -3 + b
b = 7
so, the full equation is
y = -3x + 7
