4/12 or 1/3 because there is 12 fractions of a clock and 5x4=20

I do not need an explanation, just a simple angle number!

Murljashka [212]

Answer:

Step-by-step explanation:

a + 143 = 180 {Linear pair}

a = 180 - 143

a = 37

37 + 93 + b = 180 {Angle sum property of triangle}

130 + b = 180

b = 180 - 130

b = 40

c + b = 90

c + 40 = 90

c = 90 - 40

c = 50

d + 120 = 180 {Linear pair}

d = 180 - 120

d = 60

? = 60 + 40 {Exterior angle property of triangle}

? = 100

Which of the expressions below have exactly 3 terms? Select all that apply.

Fynjy0 [20]

Answer:

C. 6x + 9 - 3x^2

Step-by-step explanation:

We have 4 expressions and are being asked which has 3 terms.

When it comes to terms, terms are numbers that are different, it could be separated through a variable, square root, symbol, e.t.c.

So when looking for an answer, we need 3 numbers with different variables or symbols, let's look

A. only has two, 10x and 8. Therefore it is wrong.

B. has 4 terms, 3x^3, 6x^2, 9x, and 12. Therefore it is wrong.

C. is correct because it has 3 terms, 6x, 9, and 3x^2.

D. has 2 terms, 833 and 12x, though 16 is there, it is the same as 833, therefore not counting it as its own term.
