(Y+40)+(x+2y)=180
3y+x=140
2x+(y+20)=180
2x+y=160
Simultaneous equation
3y+x=140
Y+2x=160
Solve for y
Y=24
3(24)+x=140
X=140-72=68

Answer:
Step-by-step explanation:
To find the LCM of two numbers, factorize both these numbers:
These two numbers have the common factor of 
Now multiply this common factor by the remaining factors:
Therefore, the LCM is 952.
Answer:
a) there is s such that <u>r>s</u> and s is <u>positive</u>
b) For any <u>r>0</u> , <u>there exists s>0</u> such that s<r
Step-by-step explanation:
a) We are given a positive real number r. We need to wite that there is a positive real number that is smaller. Call that number s. Then r>s (this is equivalent to s<r, s is smaller than r) and s is positive (or s>0 if you prefer). We fill in the blanks using the bold words.
b) The last part claims that s<r, that is, s is smaller than r. We know that this must happen for all posirive real numbers r, that is, for any r>0, there is some positive s such that s<r. In other words, there exists s>0 such that s<r.
