Answer:

-3=x

Step-by-step explanation:

First you must add the X's on each side which gives you: 1x-2= -x - 4 - 4

Next you must add the first number 4 to the - 2 on the other side.

Then you do the exact same thing with the other number 4.

After that you get 1x+6=-x, then you subtract the 1 x with the -x to get 6= -2x.

Finally divide  both sides by 2 and your final answer is -3 = x

Guys help me with a) and b) tasks<br>ANSWER:<br>a) 40<br>b) 25<br>Thanks&lt;3​
umka21 [38]

Step-by-step explanation:

there are 2 similar triangles : ABE and DCE

that means they have the same angles, and the scaling factor from one triangle to the other is the same for every side.

and that means that

DE/AE = EC/BE (= DC/AB)

we know that

AE = AD + DE

BE = BC + EC

a.

so, we have actually

DE/(AD+DE) = EC/(BC+EC)

DE/(10+DE) = 8/(2+8) = 8/10 = 4/5

DE = 4(10+DE)/5

5DE = 4(10+DE) = 40 + 4DE

DE = 40 cm

b.

AD/DE = 3/5

BC/EC must be 3/5 too.

15/EC = 3/5

15 = 3EC/5

75 = 3EC

EC = 25 cm

The exterior angle of a regular polygon is 15 degrees how many sides does it have
Komok [63]
The formula to use is
n = 360/E
where 
n = number of sides
E = measure of exterior angle

In our case, E = 15 so 
n = 360/E
n = 360/15
n = 24

This regular polygon has 24 sides

The difference of a number times
Hunter-Best [27]
7 x  - 5 = 8 
7 x = 8 + 5
7 x = 13
x = 13/7 


7 ( 13/7) - 5 = 8 
91/7 - 35/7 = 56/7
56/7 = 56/7 = 8
