Think of this as a fraction. Lets think the fraction is based off of the number "4"  4,8,12,16  Makes the fraction 1\4 (because there's 4 numbers total)  then lets add the extra 2 numbers of 4+4.....4,8,12,16,20 ,24 .    that makes 1\6.  so now all you do is convert the fraction into a percentage.

A formula is given as J = 10V/11 + 143
Nadusha1986 [10]

Answer:

11j - 1573/10

Step-by-step explanation:

J = 10v /11 +143

collect terms

J - 143 =10v /11

11 (J -143) = 10v

Divide both sides by 10

11(J - 143)/10 = v

v = 11J - 1573/10

Hope this helps!

The sum of 3 times a number and 9 equals 4 use the variable b for the unknown number write in an equation​
Flauer [41]

Answer: b= -5 over 3

Step-by-step explanation:

create the equation 3b + 9 = 4

subtract 9 from each side to isolate the variable

we are left with 3b = -5

to further isolate the variable divide by 3

3b/3 = -5/3

3b divided by 3 is b, which is equal to -5 divided by 3; -5/3

b = -5/3 is your answer
