If we add the equations it looks like
-5y + 8x + 5y + 2x = -18+58
so 10x=40
so x=40/10=4
now let's replace x by 4 in the second equation
5y +2*4=58
5y=58-2*4=58-8=50
so y=50/5=10
so (x, y) = (2, 10)
Answer:
x=1/2
Step-by-step explanation:
Distribute the 10. it will be 20x-40=100x. Subtract 20x from both sides. it will be 40=80x. Divide by 80 to leave the x by itself. x=40/80...in simplify form....its 1/2
3.5 feet converted to inches is 42 inches. 42"-14"=28"
28" divided by 2 sides is 28/2 = 14" on either side if the poster remaining
Answer:
5, 2x2 and 4
Step-by-step explanation:
Terms are expressions or characters that are separated by a plus or minus sign.
therefore, the terms are 3x, 5, 2x2 and 4
like terms have the same have the same variables or no variables attached to them.
like terms = 5, 2x2, and 4
Note: 2x2 = 4
