How to solve for<br> LN and what are the variables

Lesechka [4]

Answer:

v See below. v

Step-by-step explanation:

LM = MN

11x - 21 = 8x + 15

$3x-21=15\\3x=36\\$

x = 12

LM = 11(12) - 21 = 132 - 21 = 111

MN = 8(12) + 15 = 96 + 15 = 111

LN = 111 + 111 = 222

Find the missing terms of the arithmetic sequence

Pavel [41]

Answer:

missing terms are -2,3,8

Step-by-step explanation:

-7, ?, ?, ?, 13

To find missing terms we add last two term and divide it by 2

so that we will get middle term

$\frac{-7+13}{2} = \frac{6}{2} =3$

so sequence becomes

-7, ?, 3, ?, 13

Again we add -7 and 3 and then divide it by 2 to get middle number

$\frac{-7+3}{2} = \frac{-4}{2} =-2$

so sequence becomes

-7, -2, 3, ?, 13

Again we add 3 and 13 and then divide it by 2 to get middle number

$\frac{3+13}{2} = \frac{16}{2} =8$

-7, -2, 3, 8, 13

So, missing terms are -2,3,8

Allushta [10]

Answer:

Distance between Gas Station and House = 7.81 miles.

Step-by-step explanation:

Given: House location ( 4, 3 ) and Gas station location ( 10, 8)

On graph 1 unit = 1 mile.

To find: Distance between Gas Station and House

We use the Distance formula to find the distance between two points $(x_1,y_1)\:and\:(x_2,y_2)$

$Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

From given points and formula,

$Distance\:between\:house\:and\:gas\:station=\sqrt{(10-4)^2+(8-3)^2}$

= $\sqrt{(6)^2+(5)^2}$

= $\sqrt{36+25}$

= $\sqrt{61}$ units

Since, 1 unit = 1 mile

⇒ $\sqrt{61}\:unit=\sqrt{61}miles=7.81 miles$

Therefore, Distance between Gas Station and House = 7.81 miles.
