(0.35x + 0.14 * 18) / y = 0.23
x + 18 = y
Answer:
Step-by-step explanation:
23). By applying triangle sum theorem in the given triangle,
(x + 83)° + (x + 48)° + 65° = 180°
2x + 196 = 180
2x = -16
x = -8
Measure of angle A = x + 48
= -8 + 48
= 40°
Therefore, Option A is the answer.
24). By triangle sum theorem,
(3x + 14)° + 90° + (4 + 3x)° = 180°
6x + 108 = 180
6x = 72
x = 12
Measure of angle A = (4 + 3x)
= 4 + 3(12)
= 40°
Therefore, Option A is the answer.

Place a dot on the 2nd line (4:05) on the timeline. Next, count each line by 5 as you leave until you count to 60 (by 5s), place a dot at 5:05 (one hour or 60 minutes). Now, count by 5s until you count to 45 and place a dot on 5:50. Thus, the answer is 1 hour and 45 minutes.
Answer: 1 hour and 45 minute
Yes, this is reasonable because he started at 4:05 pm and ended at 5:50 pm which is exactly 1 hour and 45 minutes later during the evening.
b) He finished in 1 hour and 45 minutes. One hour equals 60 minutes, thus, 60 minutes + 45 minutes = 105 minutes.
Answer: 105 minutes
{hint: start counting as you leave each dot do not count the dot which you start at)
