2/5x + 1/8x + x
If y=3 find 2 1/9-3y + 2
(2/5)x + (1/8)x + x.
2x/5 + x/8 +x = 16x/40 + 5x/40 + 40x/40 = 61x/40.
Y = 3.
2 1/9 - 3y + 2 = 19/9 - 3*3 + 2 = 19/9 - 81/9 + 18/9 = -44/9.
To simplify the expression 2/5x + 1/8x + x, we need to first find a common denominator for the fractions involving x. The common denominator for 5x and 8x would be 40x.
Let's rewrite the expression with a common denominator:
(2/5)*40x + (1/8)*40x + 40x
Now we can simplify:
(2/5)*40x can be rewritten as (2*40)/(5*1)*x, which equals 80x/5x or 16x.
(1/8)*40x can be rewritten as (1*40)/(8*1)*x, which equals 40x/8x or 5x.
Plugging these simplified expressions back into the original expression:
16x + 5x + 40x
Now we can combine the like terms by adding the coefficients of the 'x' term:
(16 + 5 + 40)x
Simplifying further, we get:
61x
So, the simplified expression is 61x.
