Well first just multiply the things in the parenthesis by 3 and get -15c + 12d and then subtract 15 from 11 (because of the c) and get -4c +12d
0.625
fraction = 5/8
percent = 62.5%
Perimeter = 2πr
2(3.14)1.5 = 9.42
Perimeter = 9.42
Answer:
Step-by-step explanation:
28 -22 38 30 -4
-26 -8 -34 20 -16
-6 -34 -24 -20 24
38 -32 36 -34 32
Answer:
a+ 3c = 26
ab - c = - 14
1/2( c + b)= 2.5or 2 and 1/2
1/2c + b = 1
4c - b = 35
