The answer would be x = -7.
Hope this helps!
Its simple what you do is you subtract not divide because if you where dividing you would be putting something into groups equally and not Addison because your not trying to find how much in all so it would be Subtraction another way is to see if there is how many more or How much more so if you see that then you know that its Subtraction! Hope this helps!:)
Answer:
= 115°
Step-by-step explanation:
Intersecting chord theorem,
"When two chords intersect inside a circle, then the measure of each angle is one half the sum of the measures of the arcs intercepted by the angle and its vertical angle."
By this theorem.
=
---------(1)
= 40°

= 100° + 60° + 30°
= 190°
By substituting these values in the expression (1)
= ![\frac{1}{2}[40+190]](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5B40%2B190%5D)
= 115°
Therefore,
= 115°
Answer:
x=-7
y=6
Step-by-step explanation:
7x+10y=11
4x+3y=-10
-3(7x+10y=11
10(4x+3y=-10
-21x-30y=-33
40x+30y=-100
19x = -133 (divide 19 on both sides)
x= -7
Now put the x in one of the original questions.
7(-7)+10y=11
-49+10y=11 (Add 49 to both sides)
10y=60 (Divide 10 on both sides)
y=6
99 16/25 or 2491/25
100-9/25= 99.64
99.64 as a mixed number is 99 16/25 or 2491/25 as an improper fraction
