Answer:
m∠2=35°, m∠1=35°
Step-by-step explanation:
∠2 and ∠4 equal 180° when added, so 180-145=35
all angles of a triangle equal 180°, so 180-∠3-∠2=∠1
180-110-35= 35
Answer:
a: 162
b: 142
Step-by-step explanation:
a: december 1=2
a: december 2=6
a: december 3 = 6 x 3 = 18
a: december 4 = 18 x 3 =54
a: december 5 = 54 x 3 =162
~ triples the number of newspapers means "x3" ~
so on the last day, 162 newspapers
B: sum up all the newspapers:
2 + 6 + 18 + 54 + 162
= 8 + 18 + 54 + 162
= 26 + 54 + 162
= 80 + 162
= 242 all in total newspapers
Friday - 185
Saturday - 185 x 2
= 370
Sunday - 370 - 50
= 320
Answer:
C
Step-by-step explanation:
3/4 + 6/10
Find a common denominator and find what you multiply to each denominator to get that number and multiply the numerator by the same amount
(3/4 * 5/5) + (6/10 * 2/2)=
15/20 + 12/20
Then add
15/20 + 12/20= 27/20
Then finally convert to mixed number
27/20 = 1 7/20
