4\left(1.75y-3.5\right)+1.25y

Answer 1

7y - 14 + 1.25y

= 8.25y - 14

Answer 2

{-\dfrac{4}{7}p+(-\dfrac{2}7p)+\dfrac{1}7}

Answer 3

First, simplify the expression by combining like terms:

= -\frac{4}{7}p - \frac{2}{7}p + \frac{1}{7}

Now, add the two terms with p:

= -\frac{4}{7}p - \frac{2}{7}p + \frac{1}{7}
= -\frac{6}{7}p + \frac{1}{7}

Answer 4

{1.17-0.07a+(-3.92a)}

Answer 5

First, simplify the expression by combining like terms:

= 1.17 - 0.07a - 3.92a

Now, combine the terms with 'a':

= 1.17 - 0.07a - 3.92a
= 1.17 - 4.99a

Answer 6

-2.5\left(4x-3\right)

Answer 7

To simplify the expression, distribute the -2.5 to both terms inside the parentheses:

-2.5(4x - 3)
= -2.5(4x) - (-2.5)(3)
= -10x + 7.5

So, -2.5(4x - 3) simplifies to -10x + 7.5.
