Answer: 63 nurses and 14 doctors
so you know the ratio is 9:2. that means for every 9 nurses there are 2 doctors. i didn't make an equation but i counted it.
if theres 9 (9*1) nurses theres 2 (2*1) doctors
if theres 18 (9*2) nurses theres 4 (2*2) doctors
if theres 27 (9*3) nurses theres 6 (2*3) doctors
you get the point so i multiplied 7 to 9 and 7 to 2, which means:
if theres 63 (9*7) nurses theres 14 (2*7) doctors
i hope this helps :)
Answer:
X = 70, y = 21
Step-by-step explanation:
53 + 6y + 1 = 6y + 54
6y + 54 = 180
180 - 54 = 126
6y = 126
126 ÷ 6 = 21
Y = 21
21 × 6 + 1 = 127
127 = 2x - 13
127 + 13 = 140
140 ÷ 2 = 70
X = 70
Opposite angles are congruent and consecutive angles are supplementary.
