Step-by-step explanation:
vertical angles or line pairs
c=60
180-120=60
180-131=49
60+49=109
180-109=71
Answer:
13 feet is remaining because
Step-by-step explanation:
12 1/4-3 1/3 (12*4=48+1=49)(3*3=9+1=10)
49/4-10/3
196-40/12

Answer:
adults=31, children = 108
Step-by-step explanation:
a + c = 139 equation 1
10a + 8c = 1174 equation 2
a=139-c isolate a from equation 1
10(139-c) + 8c = 1174 substitute a value into equation 2
1390-10c + 8c = 1174
-2c = -216
c = 108
use value of c in either equation to find value of a
a + c = 139
a + 108 =139
a = 31
Answer:
105 km
Step-by-step explanation:
Written as a proportion, the ratio of km to cm will be the same for both distances:
(x km)/(17.5 cm) = (15 km)/(2.5 cm)
x km = (15 km)(17.5/2.5) = 105 km
105 actual kilometers are represented by 17.5 cm on the map.
