Answer:

Step-by-step explanation:

4x + 15 = 3

Subtract 15 from both sides

4x + 15 - 15 = 3 - 15

4x = -12

Divide both sides by 4

4x/4 = -12/4

x = -3

Check:

substitute x = -3 in the LHS of the  equation,

4*(-3) + 15 = -12 + 15

                 = 3 = RHS

The variable z is directly proportional to x, and inversely proportional to y. when x is 16 and y is 17, z has the value 11.2941
Tresset [83]

Lets suppose k is the constant of proportionality.

z = k * x / y

when x is 16 and y is 17, z has the value 11.294117647059

11.294117647059 = k * 16/17

Multiplying 17 on both sides

11.294117647059 * 17 = k * 16

192 = k * 16

Dividing 16 on both sides

192/16 = k

k = 12

Now when x= 22, and y= 26

z = k * x/y

z = 12 * 22 / 26

z = 10.1538461538 : Answer

Hope it will help :)

P=s1+s2+s3 solve for s3
tresset_1 [31]

P=s1+s2+s3

Move +s1 to the other side. Sign changes from +s1 to -s1

P-s1=s1-s1+s2+s3

p-s1=s2+s3

Move s2 to the other side. Sign changes from s2 to -s2

p-s1-s2=s2-s2+s3

p-s1-s2=s3

Answer: p-s1-s2=s3
