Maria stated that 5/6 is between 4/5 and 6/7<br> Do you agree? Give reasons for your answer.

ira [324]

Answer:

Yes, because look at the below work.

Step-by-step explanation:

Step 1: Find the Common Denominator

The common denominator is 210

5/6 * 35/35 = 175/210

4/5 * 42/42 = 168/210

6/7 * 30/30 = 180/210

5/6 is between 4/5 and 6/7 because 4/5 = 168/210 which is less than 5/6 which is 175/210 and 5/6 is less than 6/7 which is 180/210.

So, yes I agree with Maria

(x + 1)^2 = 3x – 1 solving Quadratics ?

Deffense [45]

Step-by-step explanation:

$(x + 1)^{2} = 3x - 1 \\ \\ \therefore \: {x }^{2} + 2x + 1 = 3x - 1 \\ \\ \therefore \: {x }^{2} + 2x + 1 - 3x + 1 = 0\\ \\ \therefore \: {x }^{2} + 2x - 3x + 1 - 1 = 0 \\ \\ \therefore \: {x }^{2} - x = 0 \\ \\ \therefore \: x(x - 1) = 0 \\ \\ \therefore \: x = 0 \: \: or \: \: x - 1 = 0 \\ \\ \therefore \: x = 0 \: \: or \: \: x = 1 \\ \\ \huge{ \red{ \boxed{\therefore \: x = \{0, \: \: 1 \}}}}$
