Ireally need an a and i'm horrible at math ): 1. solve the following equation algebraically, show your work 6 = x+2 over 3 2.solve the following equation algebraically, show your work 13 + w over 7 = - 18 3. solve the following equation algebraically, show your work 17 = -13 - 8x example: 1 over 5 would mean a fraction i just don't want anyone confused

See the attached picture for 2 options for question 1 and 2 depending on how the fractions are written.

Question #3:

17 = -13 - 8x

Add 13 to each side:

30 = -8x

Divide both sides by -8:

X = 30 / -8

X = -3 3/4

300 bags of 20 kg  of premixed are required.

Step-by-step explanation:

Given:

diameter of pond 'd'= 7 m (given)

radius of inner border of pond 'r'= d/2= 7/2 m

The radius of outer circular border 'R'= r+2= 7/2+2= 11/2m

Area of concrete border around the circular pond= area of outer circle- area of inner circle

So,

=> 22/7 x ((11/2)²-(7/2)²)

=> 22/7 x (121/4-49/4)

=>

=> 56.57 m²

volume of concrete needed= area x height= 56.57 x 0.05= 2.8285 cubic meter

Since 1 cube meter requires 106 x 20 kg bags,

2.8285 cubic meters require bags= 2.8285x106x20 kg

20 kg bags of premixed concrete required= 2.8285x106x20/20

=> 2.8285x106

=> 299.821 or 300 approximately
