Answer:
x = 3
Step-by-step explanation:
6x + 2x - 5= 19
8X -5 = 19
8x = 24
x = 3
Step-by-step explanation:

The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
Answer:
c. sin 8x + sin 2x
Step-by-step explanation:
1. Convert the product into sum or differences: 2 sin 5x cos 3x
Solution:
2 sin 5x cos 3x = sin (5x + 3x) + sin (5x -3x), [Since 2 sin A cos B = sin (A + B) + sin (A - B)]
= sin 8x + sin 2x
12/30 is the fraction 0.4 is the decimal all you do is put the fraction of kids who can stay in the numerator (top) and the kids who can't stay in the denominator (bottom) hope this helps hope i am brainliest i need one more
