Answer:
∠ 3 = 63°
Step-by-step explanation:
∠ 2 and ∠ 3 are adjacent angles and supplementary, thus
∠ 2 + ∠ 3 = 180°, that is
117° + ∠ 3 = 180° ( subtract 117° from both sides )
∠ 3 = 63°

Answer: 8
Step-by-step explanation: Substituting x for 2 since we know the value, 4(2) is 8.
Answer:
Step-by-step explanation:
Start by removing the brackets.
Left Brackets
30(1/2 x - 2)
30*1/2 x - 30*2
15x - 60
Right Bracket
40(3/4 y - 4)
40*3/4 y - 4*40
10*3 y - 160
30y - 160
Now put these 2 results together.
15x - 60 + 30y - 160 Combine the like terms.
15x + 30y - 220 That's one answer Others are possible.
5(3x + 6y - 44)
Answer:
7/10 can't be simplified, 2/10->1/5
Step-by-step explanation:
7/10 cannot be simplified as 7 and 10 don't have any common factors other than 1
2/10 can be simplified by a factor of 2 to get 1/5
