3х — 7y = 21

Mathematics
1 answer:
Zolol [24]3 years ago
7 0
Answer:

Explanation:

3x - 7y = 21

6x = 14y + 42
Or 6x - 14y = 42

3x - 7y = 21 (1)
6x - 14y = 42 (2)
———————
-2(3x - 7y = 21)
6x - 14y = 42
———————
-6x + 14y = -42
6x - 14y = 42
———————
0x + 0y = 0

So I think in this case x and y has infinitely many solution

Kiara has a ribbon that measures 1/4 of an inch and Jillian has a ribbon that measures 2/3 of an inch. Jillian says their ribbon
fenix001 [56]

Answer:

Jillian is Incorrect as fraction can never be balanced based on numerator or denominator.

Step-by-step explanation:

Given:

Measure of ribbon Kiara has = \frac{1}{4} \ inch

Measure of ribbon Jillian has = \frac{2}{3} \ inch

Now given:

Jillian says their ribbons are equal in length because her numerator is one more than kiara's and her denominator is one less, therefore balancing the two fractions.

we need to find whether statement is correct or not.

First we will find the decimal value of the given fraction's

\frac{1}{4} \ inch can rewritten as 0.25\ inch

Measure of ribbon Kiara has = 0.25 inch

\frac{2}{3} \ inch can be Rewritten as 0.67\ inch

Measure of  ribbon Jillian has = 0.67 inch

Now we can see that;

0.67 inch is greater than 0.25 inch.

Hence we can say that ribbons are not in equal length.

Also the fraction can never be balanced by decreasing or increasing the numerator or denominator.
