Move the -4 to the right (+4 on both sides). now you have 4y=20. divide both sides by 4. y=5
Decimal form: 2.03 (rounded)
If you want to keep the fraction form, it is simplified to the farthest point without taking it out of the improper form
Number 5 is 135 because angle 3 is congruent to 7 and 7 is 135
Note that (a^b)^c=a^(bc) so in this case we have:
(27^(1/3))^2 the cube root of 27=±3
(±3)^2 and ±3^2=9
So the equivalent expression is 9 or if you need an exponent 9^1 :)
I am assuming that you meant 27^(2/3)
2 goes into both numbers, so divide both by 2;
10 ÷ 2 = 5
42 ÷ 2 = 21
so 10/42 in simplest form is: 5/21
