Answer: j = 8
Step-by-step explanation: To solve for <em>j</em> in this equation, we want to get <em>j</em> by itself on the left side of the equation. Since <em>j</em> is being multiplied by 5, to get <em>j</em> by itself, we need to divide by 5 on the left side of the equation. Since we divided by 5 on the left side, we must also divide by 5 on the right side.
On the left side, notice that the 5's cancel out so we are simply left with <em>j</em>. On the right side, we have 40 divided by 5 which gives us 8 so we have j = 8.
Finally, remember to check your answer by substituting an 8 back into the original equation. So we have 5 (8) = 40 which is a true statement so our answer checks. Remember to show all your work when solving equations.

hope it helps!
btw that my actual answer. it really long.
Answer:
Total of 9 lengths of 4 inches can be taken out from a board of 3 feet
Step-by-step explanation:
length of board in feet = 3 ft
As
1 ft = 12 inches
So
Length of board in inch = 
= 36 inches
Let no of 4 inches length be = x
The equation become
Total of 9 lengths of 4 inches can be taken out from a board of 3 feet
Answer:
Part A: a coefficient is either 20 or 35, both work. A variable is c or w, again either work. The constant is 23.50.
Part B: He will have $503.50
Part C: The coefficient would change, because the amount per car changes, not the amount of cars.
Step-by-step explanation:
A coefficient goes in front of the variable (which is the letter, usually shown as x). The constant is a number with no variable attached.
We replace c with 20, and w with 12, giving us 20(3)+35(12)+23.50 for our equation. After multiplying, we come up with 60+420+23.50, which equals 503.50.
