Question

Упростите выражения 1,5х + 3*(х+0,83) 1,2*(у+5)-1,7

Answer 1

1) 1,5x+3*(x+0,83)=1,5x+3x+2,49=4,5x+2,49 2) 1,2*(y+5)-1,7=1,2y+6-1,7=1,2y-4,3

Answer 2

I can help you with math problems. To simplify the expression 1.5x + 3(x + 0.83) + 1.2(y + 5) - 1.7, we need to apply the distributive property and combine like terms. The distributive property states that a(b + c) = ab + ac. Using this, we can rewrite the expression as:

$$ 1.5x + 3x + 2.49 + 1.2y + 6 - 1.7 $$

Next, we can combine the terms that have the same variable or are constants. We have 1.5x and 3x, which are both terms with x. We can add them together to get 4.5x. We also have 2.49, 6, and -1.7, which are all constants. We can add them together to get 6.79. The term 1.2y does not have any other term with y, so we leave it as it is. The simplified expression is:

$$ 4.5x + 1.2y + 6.79 $$

This is the final answer. I hope this helps.Ответь+подробно.+Упростите+выражения++1,5х+++3*(х+0,83)+1,2*(у+5)-1,7
