5 I think ................................................
I believe the answer is 2.4, because 24/10= 2.4. To check this answer, multiply 10 by 2.4. :)
Answer:
1) x = 3
y = 42
2) x = 50
y = 70
Step-by-step explanation:
1) 12x + 6 = 14x
6 = 2x
x = 3
14(3) = y
42 = y
2) 2x + 10 + x + 20 = 180
3x + 30 =180
3x= 150
x=50
2(50)+10=110
110-180
y=70
Question:<u /> <em>Simplify the trigonometric expression sec</em><span><em>Өcos</em></span><span><em>Ө.</em></span>
For each of the three basic trig functions, (sin, cos, tan) there are three more which act as their reciprocals. (csc, sec, and cot respectively)
Reciprocals, of course, are flipped fractions. If you have some number x, the reciprocal can be expressed as
.
An important property of reciprocals is that if you mutliply them together they will cancel out--take
for example.
