We can do the elimination method to find the solution for this problem. The elimination method involves adding the two equations together to get rid of a like term.
x + 2y = 7
+ x - 2y = -1
—————————
2x = 6
Now that we eliminated 2y because they cancel out, we are left with 2x = 6. Divide both sides by 2 in order to get x.
The answer is: x = 3.
Now that we know the numerical value of x, all we have to do is plug x into either system of equation in order to find the numerical value of y.
x + 2y = 7
3 + 2y = 7
2y = 4
y = 2
The solution to the problem is (3, 2).
Answer:
x = 2.4
Step-by-step explanation:
For this equation, you need to use trigonometry. we only need to use one of the two angles given and for this example i'm going to use the 60° angle. as we know the adjacent side and want to know the opposite side, we need to use the trig ratio tan
in this case, we will replace the adjacent side with
the square root of 2.
= 
as the side we know is on the bottom of the ratio, we need to multiply it by the ratio (tan) then the angle (in case you don't know, * means multiply)
round to 1 decimal place
x = 2.4
Hope this was helpful :-)
I'm sorry if this was confusing, trigonometry is very hard to explain.
Answer:
you keep multiplying by five
Step-by-step explanation:
So 1 x 5 is five, 5 x 5 is 25, 25 x 5 is 125, so on and so forth.

Answer:
its B
Step-by-step explanation: its the only "division" thing. and 15-14 is 1 not 2 so its B
