6x - 2x = 16
4x = 16 |divide both sides by 4
<h3>x = 4</h3>
Answer:

Step-by-step explanation:
in powers:
when there is x to the power of 6 to the power of 6 as an example you should multiply 6x6=36
so in this one try to do it like the one up there
6*
=3 so it is 
Answer:
x = -2/5
x = 1
Step-by-step explanation:
5x² - 3x - 2 = 0
(5x + 2)(x - 1) = 0
⇒ 5x + 2 = 0
⇒ 5x = -2
⇒ x = -2/5
⇒ x - 1 = 0
⇒ x = 1
W=2L
P=300=2(L+W)
so
300=2(L+W)
divide by 2
150=L+W
W=2L
subsitute
150=L+2L
150=3L
divide by 3
50=L
sub back
W=2L
W=2(50)
W=100
the field is 100yd wide by 50yd long
Cost depends on the class size , so
cost is the dependent variable and class size is the independent.
