How do I solve this equation 144=-12(x+5)

1 answer:

6 0

First you distribute the -12 to the (x+5) getting 144=-12x-60.

Next you add 60 to each side getting 204=-12x

Then you divide each side by -12 getting -17=x, which is the answer.<span />

Fernando will divide 0.24 by 4 to help him solve a math problem. Which model below could represent this math problem

balandron [24]

Answer:

So the model should represent either $\frac{6}{100}$ or $\frac{3}{50}$ (its equivalent and simplified form.

Step-by-step explanation:

1) Originally the question wants to represent this quotient as tiles.

So, $\frac{\frac{24}{100}}{4} =\frac{24}{100} *\frac{1}{4} =\frac{6}{100}=$

We can still simplify it, but since we're dealing with 100 x 100 squares let's keep it this way

2) So the model should represent either $\frac{6}{100}$ or $\frac{3}{50}$ (its equivalent and simplified form.

Solve x-5y=-30, 3x+5y=10 show your work

marin [14]

1) x = 5y - 30

2) x = - 1.6y + 3.3

<em>im assuming these are 2 different questions</em>

<h3>Explanation:</h3><h3>1)</h3>

Start with the equation:

x - 5y= -30

add 5y to both sides:

x = 5y - 30

Your answer is x = 5y - 30

Start with the equation:

3x+5y=10

subtract 5y from both sides:

3x = -5y + 10

divide by 3 to get x singular

x = - 1.6y + 3.3

Your answer is x = - 1.6y + 3.3

Hope this helps :)
