Answer:
a) 148.52
Step-by-step explanation:
If sum of two angles is 180, then they are supplementary
Ratio = 10 : 47
Smaller angle = 10x
Larger angle = 47x
10x + 47x = 180
57x = 180
Divide both sides by 57
x = 180/57
x = 3.16
Larger angle = 47x = 47 * 3.16 = 148.52
Answer:
1/2
Step-by-step explanation:
1/3 + 1/6
LCM of 3 and 6 is 6.
therefore, multiple the fraction that doesn't have 6 as denominator with a fraction that makes the denominator equal to the LCM.
1/3 × 2/2 = 2/6
(we have used 2/2 because 3×2= 6)
so,
2/6+1/6 = 2+1/6
(2 + 1 whole divided by 6)
therefore we get,
3/6
on simplification,
3/6 = 1/2 = 0.5
hope it helps!!

Answer:
- Melissa: 30
- Ryan: 23
- Chau: 69
Step-by-step explanation:
Let r represent the number of messages Ryan sent. Then Chau sent 3r and Melissa sent r+7. Their total was ...
(r+7) +(r) +(3r) = 122
5r +7 = 122 . . . . . collect terms
5r = 115 . . . . . . . . subtract 7
r = 23 . . . . . . . . . . divide by 5
Ryan sent 23, Melissa sent 30, and Chau sent 69 text messages.
