a. 7x + 52 (2x + 5x) (40 + 12)
b. 13x + 142 (2x+5x+6x) (40 + 12 - 10)
c. 246 (16 + 40 + 40 + 100 + 12 + 48 - 10)
X=7, y=3
because it is an algebraic method you have to solve for an x or y in either equation, and then plug that into the other equation. it’s helpful for these problems to check your work and plug the numbers back into the equations and the end for future reference !
Answer:
-1
Step-by-step explanation:
because when y is 2, x is -1
4 rows because 4 times 8 equals 32, so then there are only 32 singers left. 64-32=32, and once again 4 times 8 equals 32.
P = 300/V
Because in order to isolate P, you have to divide V on both sides.
