Answer:
z=40 degrees
Step-by-step explanation:
a triangle is 180 degrees
<ACB=50 (180-130=50)
50+90=140
180-140=40
<span>First, you would need to simplify both sides of the equal sign. (It is already simplified as much as possible).
-2y + 1 = y - 5
</span>
Now, you would need to combine like terms on both sides of the equation. Remember, y = 1y.
-2y + 1 = y - 5
-3y = -6
Now, all you would have to do is isolate the x. To do this, you would divide both sides by -3.
-3y = -6
y = 2
I hope this helps!
Lets write an equation for each guy's shots and score:
4A + 2B = 18
3A + 3B = 21
To solve we multiply the first equation by -3 and the second by 2:
-12A - 6B = -54
6A + 6B = 42
--------------------
-12A + 0 = -12
A = 1
to find B we substitute in the first equation:
<span>4A + 2B = 18
</span><span>4(1) + 2B = 18
</span><span>4 + 2B = 18
</span>2B = 14
B = 7
therefore there were given 7 points in an arrow in B
