Add up the same sides of both equations to eliminate <em>x</em> :
(<em>x</em> - 2<em>y</em>) + (-<em>x</em> + 3<em>y</em>) = 8 + (-5)
(<em>x</em> - <em>x</em>) + (-2<em>y</em> + 3<em>y</em>) = 8 - 5
<em>y</em> = 3
Then
<em>x</em> - 2<em>y</em> = <em>x</em> - 6 = 8 → <em>x</em> = 14
Therefore, half of 1/4 is 1/8. 1/4 means 0.25 if you devide it by 2 you will get 0.125 so 1/8 is half of 1/4.
Answer:
x = 5
m∡B = 66°
Step-by-step explanation:
these two angles are same-side interior angles, which are supplementary
8x + 74 + 2x + 56 = 180
10x + 130 = 180
10x = 50
x = 5
m∡B = 2(5) + 56 = 66°
0.91÷-0.13
=-7
hope this helps!
Answer:
yes because 6(-2x) its 6 time -2 so its 13
