Answer:
f = 65
Step-by-step explanation:
6.50*21+f=201.50
We need to isolate f
1. multiply 6.50 by 21. 6.50 * 21 = 136.5
136.5+f= 201.50
2. Since 136.5 is positive and not being subtracted we will...
Subtract 136.5 from both sides
136.5-136.5=0+f
201.50-136.50 = 65
thus leaving f = 65
Answer:
14
Step-by-step explanation:
6 (1) + 4(-3) + -1 = -7
A = 1
B = -3
C = -1
------------------
Plugged it in:
-2(-1) - 12(1) - 8(-3) = 14
******
2 + -12 + 24 = 14
-1 (5x 11) i hope that helps
