10(1 + 4a) - 7a = -6a + 5(1 + 8a)

yulyashka [42]

10(1 + 4a) - 7a = -6a + 5(1 + 8a)

10 + 40a - 7a = -6a + 5 + 40a
-40. -40

10 - 7a = -6a + 5
-7a + 6a = 5 - 10
-a = -5
5 = a

Please help me ......................

jekas [21]

Answer:

n = 18

Step-by-step explanation:

The formula for angle sum of a polygon is S = 180 (n - 2), where S is the sum and n is the sides.

We are given that the sum is 2880, and are trying to find n.

Simply sub in S = 2880,

2880 = 180 (n - 2)

Divide by 180 to get (n - 2) by themselves on the right side,

16 = n - 2

Now add 2 to the other side to get n by itself

18 = n

n = 18

Hope this helped!! Please feel free to ask me if there's anything you don't understand from this working

It is about :<br>Length of line segment in the rectangular coordinate system

ella [17]

If a segment is horizontal, its length is the difference between its x coordinates. If the result is negative, you need to consider the absolute value (or just pick the coordinates in the correct order, i.e. the bigger minus the smaller).

So, we have

$CD = D_x-C_x=6-1=5$

$EF = F_x-E_x=-2-(-8)=-2+8=6$

Answer:

x = -3

Step-by-step explanation:

(x - 2)^3 + 13 = -112

Subtract 13 from both sides

(x - 2)^3 = -125

Take the cube root of both sides

x - 2 = -5

Add 2 to both sides

x = -3

Complete the remainder of the

N76 [4]

Answer: 2, 4, 6, 8

Step-by-step explanation:

Just plug x into the equation for each one.

x = -3

$y=\frac{2(-3)}{3} +4\\y=\frac{-6}{3} +4\\y=2$

With this one, you can see it is a linear equation and for every increase of 3 on x, y in increased by 2.

x -6 -3 0 3 6

y 0 2 4 6 8
