Answer:
a = 12.93
Step-by-step explanation:
Convert to decimal: 12 1/3 = 12.3
Pythagoras (a^2 = b^2 + c^2):
4^2 = 16
12.3^2 = 151.29
16+151.29 = 167.29
a = √167.29
a = 12.93 (rounded to two decimal places)
21$
24+x=45
-24 -24
x=21$
x = -2.9
y = 2.6
x+y = -2.9+2.6
= -0.3
78 is 7 divided by 8, which equals 0.875. So an equivalent fraction is another fraction that also equals 0.875.
