Answer:
118 degrees; 30 degrees
Step-by-step explanation:
2x+14=1/2((6+14x)-58)
2x+14=1/2(-52+14x)
2x+14=-26+7x
40=5x
x=8
6+14(8)=6+112=118
2(8)+14=16+14=30
If you were to buy 5 yards at $14 a yard, your first cost would be at $70. But with 14 being 20% of 70, you would subtract 14 out of the $70, which would leave your final cost at $56.
Answer:
64 ounces
Step-by-step explanation:
We will use the substitution:
t = x² ;
t² + 21 x - 100 = 0
t² + 25 t - 4 t - 100 = 0
t ( t + 25 ) - 4 ( t + 25 ) = 0
( t + 25 ) ( t - 4 ) = 0
t 1 = - 25, t 2 = 4
x = √t
Answer:
The roots are:
x 1 = 5 i
x 2 = - 5 i
x 3 = - 2
x 4 = 2
Just imagine having 6 one blocks. Then you have 7 groups of those 6 one blocks. Then that's it!
