7/10 because there is two places after the decimal point making it 100 so move the decimal point two places to the right which makes it 70 and 70/100 in simplest form is 7/10 <span />
<u>Answer:</u>
(-1, 5)
<u>Step-by-step explanation:</u>
The center of a circle is the midpoint of the diameter.
So we have to calculate the midpoint of the diameter, using this formula:
midpoint = ( 
, 
)
= (
, 
)
= (-1, 5)
∴ The center of the circle lies at the point (-1, 5).
Answer:
Step-by-step explanation:
A symbol for a value we don't know yet. It is usually a letter like x or y.
Example: in x + 2 = 6, x is the variable.
Why "variable" when it may have just one value? In the case of x + 2 = 6 we can solve it to find that x = 4. But in something like y = x + 2 (a linear equation) x can have many values. In general it is much easier to always call it a variable even though in some cases it is a single value.
All you need to do is <u>Divide</u><u /> 84 from 672.
