Answer:
126
Step-by-step explanation:
since b is 54 just subtract 54 from 180 to get a as they are in a sttaight line
Answer:
Two terms
Step-by-step explanation:
First, we have to simplify reducing the number of terms, since there are like terms
x-5+16x+4-2x-3
Eventually, you'll get 15x-4, thus there are two terms.
Please correct me if I'm incorrect, and I'll change the answer, but I hope I helped :)
A graph shows the solutions to be
(x, y) = (-6, 312) or (6, 312)To solve algebraically, remove a factor of 2 from the second equation and use that expression to substitute for y in the first equation.
10x^2 -(8x^2 +24) = 48
2x^2 = 72
x = ±√(72/2) = ±6
y = 8*36 +24 = 312
Answer:
C)
Step-by-step explanation:
(-2x -1) - (x - 7)
distribute the negative through the second set of parenthesis
-2x - 1 - x + 7
- 3x + 6
