Add the zeros on to 7.5 to which you would move the decimal and it should be like this 750.0 or 750
Answer:
Step-by-step explanation:
The third, fifth and sixth expressions (from the top) are NOT polynomials, and the reason in each case is that the expression has one or more negative powers of x in it.
Let the first and smaller number be x. Since the second number is 5 times the first, the second number is 5x. We also know both of these numbers must add to 50; thus, we can create the following equation.

Combine like terms

Divide both sides by 6

This is the value of the first number. The number you're looking for isn't specified in the question description, so I'll just provide the value of the second number. The second number has to be 5 times the first.
Thus, we just multiply 5 to x.

That's the value of the second number.
Answer:
100°
Step-by-step explanation:
Total angle in a triangle is 180
∠C = 180 - 20 - 60
= 180 - 80
= 100
