In “modeling with linear equations” how do i solve -11-8x=-3x+19

Mathematics
1 answer:
user100 [1]3 years ago
5 0

Answer:

x = -6

Step-by-step explanation:

-11 - 8x = -3x + 19 (Move constants to right side)

-8x = -3x + 19 + 11 (Move x to left side)

3x - 8x = 30 (simplify)

-5x = 30 (divide both sides by -5)

x = -6

kathy uses a 1/2 cup of milk with every bowl of her favorite cereal if there are only 3 3/5 cups of milk left, then how many bow
Murrr4er [49]

Taking a quotient, we will see that she can make 7 bowls of cereal (and some leftover milk).

<h3>How many bowls of cereal would kathy have?</h3>

We know that for each bowl, she needs 1/2 cups of milk.

And we also know that she has a total of (3 + 3/5) cups of milk.

To know how many bowls she can make, we need to take the quotient between the total that she has and the amount that she needs for each bowl:

(3 + 3/5)/(1/2)

We can rewrite the total as:

3 + 3/5 = 15/5 + 3/5 = 18/5

Then the quotient becomes:

(18/5)/(1/2) = (18/5)*2 = 36/5 = 35/5 + 1/5 = 7 + 1/5

So she can make 7 bowls of cereal (and some leftover milk).
