Answer:

∠x = 80°

∠y = 140°

∠z = 20°

Step-by-step explanation:

  • the sum of the interior angles of a triangle is 180°
  • the measure of third angle = the sum of the interior angles - the sum of two angles

x = 180 - (60 + 40) = 80

∠x = 80°

  • the measure of 40 and ∠y are on the straight line and they are both equal 180°

then to find the value of y = 180 - 40

y = 180 - 40 = 140

∠y = 140°

z = 180 - (140 + 20) = 20

∠z = 20°

Use associative property of addition to find the total of 1, 10, and 18 in two different ways
allochka39001 [22]
1 + 10 + 18 = (1 + 10) + 18

1 + 10 + 18 = 11 + 18 

1 + 10 + 18 =  29

OR

1 + 10 + 18 =  1 + (10 + 18)

1 + 10 + 18 = 1 + 28

1 + 10 + 18 = 29

Which expression represents a simplified form of the expression:
Elden [556K]
<span>2+3(x-3)+1-5(2-x)

The first thing we must do is distribute...

2 + 3x - 9 + 1 - 10 + 5x

Then we must combine like terms. We can combine terms with an x together and we can combine terms without an x together.

2 - 9 + 1 - 10 = -16
3x + 5x = 8x

So our simplified expression is C. 8x - 16</span>

On the following number line, two rational numbers are graphed.Represent the two numbers as fractions (or mixed numbers) in lowe
nordsb [41]
The first graphed rational number is at the middle of -2 and -1, thus the number represented is -1 \frac{1}{2}

The second graphed number is five out of six places from from 0 to 1, thus the number graphed is 0+ \frac{5}{6} = \frac{5}{6}

The difference between the two numbers can be represented as
-1 \frac{1}{2} - \frac{5}{6}
or
\frac{5}{6} -(-1 \frac{1}{2} )= \frac{5}{6} +1 \frac{1}{2}

To find the difference,

-1 \frac{1}{2} - \frac{5}{6} \\ \\ =-1 \frac{3+5}{6}  \\  \\ =-1 \frac{8}{6} =-2 \frac{2}{6}  \\  \\ =-2 \frac{1}{3}

Also,

\frac{5}{6} +1 \frac{1}{2} \\  \\ =1 \frac{5+3}{6}  \\  \\ =1 \frac{8}{6} =2 \frac{2}{6}  \\  \\ =2 \frac{1}{6}
