1) <span>B)3x+6y=22
6x+12y=44
because the equations are equivalent to each other
2*(3x+6y=22) -----> 6x+12y=44
2) </span><span>5x+10y=15 should be multiplied by -2, to get 5x*(-2)=-10x, and x then can be eliminated
</span><span>A)-2</span>
Answer:
Step-by-step explanation:
with a 45-45-90 triangle the hypotenuse is equal to the length of one of the legs times the square root of 2.
if one of the legs is 1.2 than the hypotenuse of this triangle should be
1.2* sqrt(2) = about 1.7

Answer:
40%
Step-by-step explanation:
Our fraction would be 22/55. You can divide and then multiply by 100 to get your percentage.
The answer is very simple:
$50 multiplied by 2 (Cause it's 200%) equals to $100
$50 multiplied by 1,2 (Cause it's 120%) equals to $60
Then, you just do the substractions, so you get $40.
