Answer:
x = 5
Step-by-step explanation:
32/4 = 8
40/8 = x
x = 5
Your subtracting 3x from 5x: 5x-3x
This is so you only have a variable on one side
Answer:
y=-5/2x+4
Step-by-step explanation:
5x+2y=8
2y=8-5x
2y=-5x+8
y=-5/2x+8/2
y=-5/2x+4
Answer:
<u> </u><u>The</u><u> </u><u>value</u><u> </u><u>of</u><u> </u><u>x</u><u> </u><u>is</u><u> </u><u>7</u><u>0</u><u>°</u><u>.</u>
Step-by-step explanation:
Let's name the angle to the right of 125° as 'y'.
y = 180 - 125 (linear pair)
<u>y = 55</u>°
Now, we know that all the angles in a triangle sum up to 180°. (Angle Sum Property)
x = 180 - (55+55)
x = 180 - 110
<u>x</u><u> </u><u>=</u><u> </u><u>7</u><u>0</u><u>°</u>
