I need help with this problem down below
Misha Larkins [42]

Answer:

y = 4

Step-by-step explanation:

Given:

y = \frac{7x + 1}{3x - 6},

To find the value of y, let's find x by solving 3x = 15.

3x = 15

Divide both sides by 3

x = 15/3

x = 5

Plug in the value of x into y = \frac{7x + 1}{3x - 6}

y = \frac{7(5) + 1}{3(5) - 6}

y = \frac{35 + 1}{15 - 6}

y = \frac{36}{9}

y = 4

A picture is x+20 cm in width and 2x-10 cm in length. The frame is a
Jobisdone [24]

Answer:

A = 1100cm^2

Step by step Explanation:

given the dimensions of width and length of the picture are x+20 by 2x-10 and the frame is a constant 5 cm wider from the edge of the picture to the frame, than the area of the frame is defined as (x+30)(2x)-(x+20)(2x-10) = 30x+200.

If the width is equal to the length which I assume is true if the width is constant.

than x+30=2x, which means x = 30.

if this is true than 30(30)+200 = 1100cm^2
