I need the answer plz

brilliants [131]

Answer:

89

Step-by-step explanation:

1. She spent a total of 23 + 30 + 16 = 69 dollars.

2. That means she had at least 69 dollars to spend. But if it were 69 dollars, that would mean she had 0 remaining dollars because she spent it all.

3. But she had 20 dollars left after she spent the 69 dollars.

4. So that means she had 89 dollars before making the purchase

I will give BRAINLIEST PLS HELP y = x + 1/2 and z = 2x - 3, which of the following is equivalent to y + yz? PLS HELP

STALIN [3.7K]

Answer:

y+yz is: $2x^2-2x-1$

Step-by-step explanation:

Given expressions are:

$y = x+\frac{1}{2}\\z = 2x-3$

The given expressions are polynomials and we have to find the value of y+yz

First of all, we will find the product of y and z

We will use the distribution to find the product.

$yz = (x+\frac{1}{2})(2x-3)\\= x(2x-3)+\frac{1}{2}(2x-3)\\= 2x^2-3x+x-\frac{3}{2}\\=2x^2-2x- \frac{3}{2}$

The next step is to add y and yz

$y+yz = (x+\frac{1}{2})+(2x^2-3x-\frac{3}{2})\\Combining\ like\ terms\\= 2x^2+x-3x+\frac{1}{2} -\frac{3}{2}\\=2x^2-2x + \frac{1-3}{2}\\=2x^2-2x+\frac{-2}{2}\\=2x^2-2x-1$

The answer is not one of the options which i assume might be a typing mistake.

Hence,

y+yz is: $2x^2-2x-1$
