Answer:
x = 40
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
126° is an exterior angle of the triangle, then
x + 2x + 6 = 126
3x + 6 = 126 ( subtract 6 from both sides )
3x = 120 ( divide both sides by 3 )
x = 40

Explanation:
The basic steps are to factor the radicand such that we pull out the -1 and we also pull out the largest perfect square factor. That way we can then apply the rule
to break up the root and simplify.
So here is how you'll get the answer.
Let x be the number of quarters in the jar.
Then 53-x is the number of nickels in the jar.
<span>We also know .25x + 0.05 (53-x) = 10.25
</span>So next, we solve for x.
.25x + 2.65 - 0.05x = 10.25
0.2x +2.65 = 10.25
0.2x = 10.25 -2.65
0.2x = 7.40
x =37
Therefore, there are 37 quarters in the jar.
53-37 is 16. So there are 16 nickels in the jar.
Hope this answer helps.
9 - 22 is -13 then add 12 yards equals -1 so they just lost one years from where they started so the answer is -1
1. y= 6
2. y= 12
3. y=18
4. y= 24
