Answer:52
Step-by-step explanation:
180-56-72=x so x is 52
D, it would have to be D, -7 + (-7) = -14, 11 * 11 = 121, x * x = x^2 0r x2 hope it helps
Answer:
I don't really know about this sorry sorry
In the step after -6x+10=4x+20, he moved the terms incorrectly. you have to add 6x to both sides so it would be 10=4x+6x+20 which simplifies to 10=10x+20. subtract 20 from both sides to get -10=10x. divide both sides by 10. the answer is x=-1
Answer:
p + q = (-2) --------(1)
p - q = 8 ----------(2)
<em><u>on</u></em><em><u> </u></em><em><u>s</u></em><em><u>i</u></em><em><u>m</u></em><em><u>p</u></em><em><u>l</u></em><em><u>i</u></em><em><u>f</u></em><em><u>y</u></em><em><u>i</u></em><em><u>n</u></em><em><u>g</u></em><em><u> </u></em><em><u>both</u></em><em><u> </u></em><em><u>equati</u></em>
8 + q = (-2)-q
q + q = (-2) -8
2q = (-10)
q = (-10)/2
q = (-5)
putting the value of q = (-5) in the equation
p + (-5) = (-2)
p = (-2)+5
p = 3
hence, p = 3 , q = (-5)
