Yes, substitute a=2.
14 - 4 + 6 - 6 = -2
8 - 10 = -2
Answer:
The answer is D
Step-by-step explanation:
I took the test and it was 1 inch equals 4 feet :)
270=2b + a
420=2a + 3c (you have to use trial and error for this)
B = 120
A = 30
C = 120
Just to check
270 = (2x120) + 30
420 = (2x30) + (3x120)
Answer:
(3/10)*15= 9/2= 4.5 hours practicing warm up routines
