Answer:
(C)SA = (1/2)(5)(12) + (1/2)(5)(12) + (5)(2) + (12)(2) + (13)(2)

2x - 4 = 40 so I put 4 under both of them and crossed it out
2x = 44 I got rid of the -4 on the left side
X=22 I got rid of the 2 on the left side by dividing it and making the answer for 1 x be simple and x=22
Answer:
y = 15
x = 43
Step-by-step explanation:
this is giving us a system of equations because we know two things:
x + y = 58
x - y = 28
take the second equation and format it where you have simplified it for one variable:
x = 28 + y
(we did this by adding y to both sides)
now substitute this new value of x into the <em>first </em>equation:
28 + y + y = 58
simplify this to get 2y = 30
divide both sides by 2: y = 15
now substitute your new value of y into the <em>second </em>equation:
x = 28 + 15
x = 43
Answer:
-¼x + y = -2
Step-by-step explanation:
First, convert to Slope-Intercept Form by moving "1" to the other side of the equivalence symbol to get <em>y</em><em> </em><em>=</em><em> </em><em>¼x</em><em> </em><em>-</em><em> </em>2, then finally convert to Standard Form by moving "-¼x" to the other side of the equivalence symbol to end up with <em>-¼x + y = -</em>2.
