Answer:

4 ÷ 6/9 is also equal to 4 x 9/6. This is because when you divide by a fraction, you change the division sign to multiply and reverse the numerator and the denominator of the fraction. For example, if x/y was a fraction, it would become y/x. THIS IS ONLY DURING DIVISION!

So, we now that 4 ÷ 6/9 is equal to 4 x 9/6. 4 x 9/6 = (4x9)/6 = 36/6 = 6.

g(x) = -X – 1

g(x) = 3

3 = -x-1

Add 1 to each side

3+1 = -x-1+1

4 = -x

Multiply by -1

-4 = x

Can someone please help me with this?? Thanks :)
larisa [96]

Answer:

m<2=60

m<1=120

m<3=120

Step-by-step explanation:

Since m<4=60 that transfers to m<2 also because they are equal. To find the other to angles you have to subtract 60 from 180 because m<1 and m<4 create a straight line that equals 180. That then also transfers to m<3.

Thank you have an amazing day.
