Ellen has a pencil 2x+15cm long. Tom has a pencil5x+25cm long. How much longer is Tom's pencil than Ellen's?

Pachacha [2.7K]

Answer:

3x + 10cm

Step-by-step explanation:

This is calculated as:

Length of Tom's pencil - Length is Ellen's pencil

Length of Tom's pencil: 5x+25cm long.

Length of Ellen's pencil : 2x+15cm long.

(5x + 25)cm - (2x + 15)cm

5x + 25 - 2x - 15

5x - 2x + 25 - 15

3x + 10 cm

Therefore, Tom's pencil is 3x + 10cm longer is than Ellen's.

Help Please.. 1 /2x + y = 4 What is the x-intercept? What is the y-intercept?

IgorC [24]

Answer:

x - intercept = 8

y - intercept = 4

Step-by-step explanation:

In order to to find x- intercept, plug y = 0, in the given equation of line.

$\frac{1} {2} x+y = 4\\\\\frac{1} {2} x+0 = 4..(plug \: y = 0)\\\frac{1} {2} x = 4\\x = 2\times 4\\x = 8\\\huge \red {\boxed {\therefore x-intercept = 8}}$

In order to to find y- intercept, plug x = 0, in the given equation of line.

$\frac{1} {2} x+y = 4\\\\\frac{1} {2} \times 0+y = 4..(plug \: x = 0)\\0+y = 4\\y = 4\\\huge \purple {\boxed {\therefore y-intercept = 4}}$
