Answer:
B
the measure of angle A: 18.6°
measure of angle B: 55.8°
measure of angle C: 105.6°
Step-by-step explanation:
6x - 6 + 3x + x = 180
10x - 6 = 180
10x (- 6 + 6) = 180 + 6
10x = 186
10x/10 = 186/10
x = 18.6
18.6 + 3(18.6) + [6(18.6) - 6] = 180
18.6 + 55.8 + 105.6 = 180
180 = 180

3 1/2r=28
3.5r=28
cross of 3.5 and r remains
divide 28 and 3.5
and r=8
r=8
Answer:
D does not show an equivalent rate
Step-by-step explanation:
we first need to find out how many words typed per minute so we divide 75 by 3 (3 divided by 3 is 1 and what we do to one side must be done to the other)
75 ÷ 3 = 25
25 word per 1 minute
now we need to multiply the minute by 25 to get the number of words typed
25(words) x 1(minute) = 25 words in 1 minute(so A is correct)
25(words) x 2(minute) = 50 words in 2 minutes(so B is correct)
25(words) x 4(minute) = 100 words in 4 minutes (so C is correct)
25(words) x 5(minute) = 125 words in 5 minutes(so D is incorrect)
