Question

7,4х+2,7у+6,3у_9,6х при х=_5 у=2

Answer 1

7,4*(-5)+2,7*2+6,3*2-9,6*(-5)=-37+5,4+12,6+48=29

Answer 2

To evaluate this expression, we can substitute the given values of x and y into the expression and then simplify it.

So, when x = 5 and y = 2, we have:

7.4x + 2.7y + 6.3y - 9.6x

= 7.4(5) + 2.7(2) + 6.3(2) - 9.6(5) (substituting x = 5 and y = 2)

= 37 + 5.4 + 12.6 - 48 (simplifying)

= 7 (simplifying further)

Therefore, when x = 5 and y = 2, the value of the expression 7.4x + 2.7y + 6.3y - 9.6x is 7.
