These two lines create vertical angles, which are congruent. That means angle z = 60 degrees. Since angle z and the angle represented by the expression 6x + 60 are supplementary (they are adjacent angles that add to equal 180 degrees), you can set up the following equation to find x:
6x + 60 + 60 = 180
6x + 120 = 180
6x = 60
x = 10
Answers:
x = 10
z = 60
Answer:
he would have a 20% chance he will pick a history book, so in decimal form it would be .2
Step-by-step explanation:
7+6+4+3=20
20*5=100
5*4=20
We can't use P = 2L + 2W because the sides have different lengths.
P = a + b + c + d
a = x
b = 2x
c = 2x - 2
d = x + 5
P = x + 2x + (2x - 2) + (x + 5)
P = <u>x + 2x + 2x</u> - 2 <u>+ x</u> + 5
P = 6x + 3
if x = 4:
P = 6 · 4 + 3
P = 24 + 3
P = 27
Answer:
See below.
Step-by-step explanation:
The 4 might be:
-1.9 - 3/2 , -1.8 and - 9/8.
Answer:
INFINITE
Step-by-step explanation:
-3(x-14)+9x=6x+42
-3x+<u>42</u>+9x=6x+42
the underlined 42 is -3 times -14.Neg*neg=positive and 3*14=42
6x+42=6x+42
