Answer:
the original amount was 62
Step-by-step explanation:
You can use the part over whole formula like this:

why?
because we know that 10% = 10/100, we can easily find out the answer by cross multiplying
? * 10 (let's use x, instead of ?)
=10x
6.2 * 100
= 620
Now we have an equation that looks like this: 10x = 620
By using the inverse operation tool (dividing each side by 10 to isolate x) we have:
x (or ?) = 62
Answer:
y=50 x=80
Step-by-step explanation:
z(3rd spot)=y=50
x=180-2*50=80
Answer:
On a coordinate plane, a parabola opens up. It goes through (negative 5, 6), has a vertex of (0, 0), and goes through (5, 6).
Step-by-step explanation:
Since you want a graph with a vertex of (0, 0), choose the one that is described as having a vertex of (0, 0).
Answer:
15 : 31
Step-by-step explanation:
750 g : 1550 g ( divide both parts by 50 )
= 15 : 31 ← in simplest form
