What's the common denominator between 210 and 770

Mathematics
1 answer:
Kipish [7]3 years ago
7 0

Suppose you want to combine the fractions 13/210 and 29/770.  What's the LCD?

Factor both 210 and 770:  3*7*10 and 7*11*10.  Form the LCD using the common factors 7 and 10 and the unique factors 3 and 11.  The LCD is thus 3(7)(10)(11), or 2310.

Then 13/210 and 29/770 become 143/2310 and 87/2310.  We can add these because their denominators are the same.

So the desired LCD is 2310.

F(x)=2x+4 when domain is {-2,0,3}
anzhelika [568]

Step-by-step explanation:

The domain is x. The range is y (or in this case F(x)).

Plug in the numbers in the number set to get a number set for your y.

When the domain is -2:

f(-2) = 2(-2) + 4

f(-2) = -4 + 4

f(-2) = 0

When the domain is -2, the range is 0.

(-2 , 0)

When the domain is 0:

f(0) = 2(0) + 4

f(0) = 0 + 4

f(0) = 4

When the domain is 0, the range is 4.

(0 , 4)

When the domain is 3:

f(3) = 2(3) + 4

f(3) = 6 + 4

f(3) = 10

When the domain is 3, the range is 10.

(3 , 10)

Answer:  The first option with sss as part of the proof

Step-by-step explanation:

The lengths of the arcs drawn in the constructions are the same, so when the line is drawn, the lengths of the sides will all be the same.  SSS is proof of congruence.

CPCTC is an acronym for "corresponding parts of congruent triangles are congruent."
