The true statement about an exterior angle of a triangle is C; It forms a linear pair with one of the interiior angles of the triangle .
An exterior angle of a triangle is equal to the sum of the opposite interior angles.
We know that the exterior angles are out of the triangle at all times and it adds up to make 180 with anyone of the inside angle of the triangle.
The pair also rests on the same straight line and that makes a pairs.
Therefore we can say that it is formed by a linear pair with one of the interior angles of the triangle.
So, the correct answer would be C.

Answer:
D
Step-by-step explanation:
The exterior angles are out of the triangle at all times and it adds up to make 180 with anyone of the inside angle of the triangle.
The pair also rests on the same flat/straight line and that makes a pair.
Therefore we can say that it is formed by a linear pair/group with one of the interior/inside angles of the triangle.
So, the correct answer would be D.

Answer:
$590
Step-by-step explanation:
The account balance is given by ...
A = P(1 +rt) . . . . simple interest rate r for t years
A = $500(1 +0.06×3) = $590
There will be $590 in the account after 3 years.
Answer:
= $90
Step-by-step explanation:
I = prt
I = 500 x 0.06 x 3
I = $90
x^2 + 2x = 42
x^2 + x + 42 = 0
x^2 + 2x + 42 = 0
Answer:
The correct answer is x^2 + x = 42.
Step-by-step explanation:
First, we need to declare the unknown, as usual we will use x for the number. Then, the square of the number will be x^2. Following the order of the statement we have that x + x^2 =42. Here we have ‘‘translated’’ the term the sum in the mathematical operation of addition. Moreover, we convert the fact that the sum of a number and its square is 42 in a equality. This is the explanation of the equation x + x^2 =42.
Finally, using that the addition is commutative we have that x^2+x=42.
The 6 in the tenths place in the number 51.66 is ten times greater in value than the 6 in the hundredths place, due to positional values in decimal numbers.
In the decimal number 51.66, the value of the 6 in the tenths place is indeed ten times the value of the 6 in the hundredths place. This is because each place to the right of the decimal point is ten times smaller than the place to its immediate left. Therefore, although both of these digits are 6, the 6 in the tenths place represents a value of 0.6 (or 6/10), whereas the 6 in the hundredths place represents a value of 0.06 (or 6/100). So, when you divide 0.6 by 0.06, you get 10, showing that the 6 in the tenths place is ten times the value of the 6 in the hundredths place.
