Answer:

b) -1.

Step-by-step explanation:

We are asked to find the value of the expression (\frac{9}{3})+4(6-7).

We will use order of operations (PEMDAS) to solve our given problem.

P: Parenthesis,

E : Exponent,

M/D : Multiply/Divide (From left to right)

A/S : Add/Subtract (From left to right)

First of all, we will remove parenthesis as:

3+4(-1)

3-4

-1

Therefore, the value of our given expression is -1.

Answer:

27 degrees

Step-by-step explanation:

We are given that Angle AEF is 63. We can also see that EAF is a right angle. Since angles in a triangle add up to 180, we can use this to solve for AFE:

Angle AEF + EAF + AFE = 180

63 + 90 + AFE = 180

153 + AFE = 180

AFE = 27

<em>Or we can solve it another way</em>

Since EAF is a right angle, the other angles are complementary (they add up to 90) so...

Angle AEF + AFE = 90

63 + AFE = 90

AFE = 27
