Answer:

6/5t + 4/15s - 3

Step-by-step explanation:

(-4/5t + 5/3s) + (-3 -7/5s + 2t)

You can only add like terms together so convert like terms to have the same denominator:

(-4/5t + 25/15s) + (-3 - 21/15s + 10/5t)

Get rid of the parentheses:

-4/5t + 25/15s - 3 - 21/15s + 10/5t

Combine like terms:

6/5t + 4/15s - 3

8) <br> Solve using the Quadratic Formula.<br><br> x2 + 3x - 5 = 0
maks197457 [2]

Step-by-step explanation:

x^{2} + 3x - 5

For any quadratic equation ax^{2} + bx + c = 0, the quadratic formula is as follows:

\frac{-b \pm \sqrt{b^{2} - 4ac}}{2a}

From the given quadratic equation, we know that a = 1, b = 3 and c = -5. Plugging in these values into the quadratic formula gives us the following:

\frac{-(-3) \pm \sqrt{(3)^{2} - 4(1)(-5)}}{2(1)}

\frac{3 \pm \sqrt{9 + 20}}{2}

\frac{3 \pm \sqrt{29}}{2}

Clay is filling 6.5 bottle of salsa, He was able to fill 7.5 bottles. How many ounce of salsa did he have? Draw an area model to
VMariaS [17]

Answer: He had 48.75 oz of salsa.

Step-by-step explanation:

I guess that Clay is filling 6.5 oz bottles of salsa.

And we know that he was able to fill 7.5 of these bottles, then if each bottle has 6.5 oz, 7.5 of them have a total mass of salsa will be equal to 7.5 times 6.5 ounces, this is:

M = 7.5*6.5 oz = 48.75 oz

This means that Clay had 48.75 ounces of Salsa

A drawn model to show this is seen below.

Each big square represents 0.5 oz, and the area black delimited area represents a total amount of 6.5 oz, we have 7 of them, then you can draw that 7 times, and count the squares, and then you will find the total ounces of salsa that Clay had, which is equivalent to the multiplication we did above.
