19
Step-by-step explanation:
when we add 9 and 10 we will get sum 19
Step-by-step explanation:
so, you don't know what a division is for ?
it is to ask things like "how often does one number fit into another number", or "how big will each piece be, if I split something into a certain number of equally sized pieces ?".
this is what we need here.
8 pizzas for $131.36. and each pizza costs the same. you see how that connects to what I just described above ?
to find how much each pizza cost, we need to divide the total price by 8, to find the size (= here the price) of each of the equally big parts of the total price.
131.36 / 8 = $16.42
Direct variations look like this (y = 3x_
Not direct variations (or inverse variations) look like this (y= 1/3x.) They are often in fraction form.
So, in your problem the direct variations are:
y= 3x
x = -1
-0.5x = y
y= 2.2x +7
y= 4
The non-direct variations are:
y = 2/7x
Answer:
57x = 1311
x = 23 hours
Step-by-step explanation:
I don't know how you would model this with two equations but the answer is 23 hours.
It would be a 1 in 4 chance
