Sorry for the drawing but what you do is add the boxes dont multiply so it will be t plus 5 plus 5 equal your answer
or 3 plus 3 plus 3 plus 3 plus 3 equals your answer
You take the x and change it to the other side to leave y by itself and then divide by 2 = Y=-3-x
Answer:145
Step-by-step explanation:x-5+3x+25=180
4x+20=180 4x=160 x=40. <k=120+25=145

3/12 =0.25
0.25 = 1/4
Answer:
D.3.5
Step-by-step explanation:
4x+2y=10(given)
2x+y=5
y=5-2x-----(1)
y=2x-1------(2)(given)
Since the left side of the equations are the the same,
5-2x=2x-1
4x=6
x=1.5
Sub x=1.5 into eq(1),
y = 5-2(1.5) = 5-3 = 2
so, x+y = 1.5+2 = 3.5
