Answer: x = 11

Step-by-step explanation:

same as the last question, set them as equal and solve. here's my work:

<em>5x - 1 = 4x + 10</em>

<em>5x - 1 (+ 1) = 4x + 10 (+ 1)</em>

<em>5x = 4x + 11</em>

<em>5x (- 4x) = 4x (- 4x) + 11</em>

x = 11

Solve for n: -16 + 3n = -(8 +5n)
umka21 [38]

-16 + 3n = -(8 + 5n)

The - sign outside the parentheses acts as a -1, and so it is distributed to each term in the parentheses.

-16 + 3n = -8 - 5n

+16

3n = 8 - 5n

+5n

8n = 8

/8

n = 1

HELPP PLEASE What is the value of x in the diagram below?
Westkost [7]

Answer:

x = 3

Step-by-step explanation:

The triangles are similar, using ratios

x            8

------ = -----------

18              48

We can use cross products to solve

48x  = 8*18

48x = 144

Divide each side by 48

48x/48 = 144/48

x =3
