What is the answer to 6(1+8n)=-39+3n

MissTica

For this case we must simplify the following expression:

$6 (1 + 8n) = - 39 + 3n$

We apply distributive property on the left side of the equation:

$6 * 1 + 6 * 8n = -39 + 3n\\6 + 48n = -39 + 3n$

We subtract 3n from both sides of the equation:

$6 + 48n-3n = -39\\6 + 45n = -39$

We subtract 6 from both sides of the equation:

$45n = -39-6\\45n = -45$

We divide between 45 on both sides of the equation:

$n = \frac {-45} {45}\\n = -1$

Answer:

$n = -1$

The question is in the picture. Plz helppp it is due tonight

Mkey [24]

Answer:

Step-by-step explanation:

We're given one equation, we have to find the other equation and solve each for 200, and whichever has the lower x is the winner

for Jayden we are given

$(0, 48), (1, 56), (2, 64), (3, 72), (4, 80)$

This looks to be a line. The y values are each separated by a common difference

We can use two points to describe the line

$m = \frac{y_2-y_1}{x_2-x_1} = \frac{80-48}{4-0} = \frac{32}{4} = 8\\ K = 8m + b\\48 = 8(0) + b\\b = 48\\so\\K = 8m + 48$

Now we can set both $K = 8m + 48$ and $K = m^2 + 10$ equal to 200

$200 = 8m + 48\\152 = 8m \\m = \frac{152}{8} = 19$

$200 = m^2 + 10\\m^2 = 190\\m = \sqrt{190} = 13.784$
