If R is the midpoint of QS, find QS. QR=5x-3 RS=21-x

Mathematics
1 answer:
steposvetlana [31]3 years ago
4 0

Answer:

QS = 34

Step-by-step explanation:

if R is the midpoint, then the two divided segments are equal to each other.

5x - 3 = 21 - x

Add x

6x - 3 = 21

Add 3.

6x = 24

Divide 6.

x = 4

Substitute this x value into any equation.

5(4) - 3 = 20 - 3 = 17

So half of QS is 17.

QS = 17 * 2 = 34

Can someone please how to do fractions in the lowest terms
VikaD [51]

Answer:

In order to out a fraction in lowest terms, you must divide by the Greatest Common Factor, or GCM, of the numerator and denominator in the fraction. Let's say we have the fraction 25/100. We know that the greastest common factor of 25 and 100 is 25, as 25 ÷ 25 = 1 and 100 ÷ 25 = 4 so 25/100 in lowest terms is 1/4:

25        25       1

___  ÷ ___ = ___

100      25       4

If the GCM of a fraction equals 1, the fraction is simplified. Because the only common factor of 1 and 4 is 1, we know this fraction is simplified.

1        1         1

__ ÷ ___ = ___

4        1        4

Hope this helps <3 Please contact me if your still confused
