The equation you describe can be written as: 5 = 6 * q - 5 - 19 This is assuming that there are no parentheses. Adding those in would change the order in which you would do the math. I will continue with the assumption that there are none. To solve the equation you should combine like terms: 5 = 6 * q - 24 Add 24 to both sides 29 = 6 * q Divide both sides by 6 29/6 = q
3/p = 6 p = 3/6 = 1/2 3/q = 15 q = 3/15 = 1/5 p - q = 1/2 - 1/5 p - q = 5/10-2/10 = 3/10
The algebraic expression is 4q-3
3.5 gallons = 3 gallons and 2 quarts-------------------Solution Method:-------------------1 gallon = 4 quartsTherefore:6 g + 1 q = 6 * 4 + 1 = 24 + 1 = 25 q2 g + 3 q = 2 * 4 + 3 = 8 + 3 = 11 q25 q - 11 q = 14 q14 q * (1 g / 4 q) = 3.5 g = 3 gallons + 2 quarts

x2 + 13x + 4 = (x + 6½ + √38¼)(x + 6½ - √38¼). To find this, we need to find p and q, where p + q = 13, pq = 4. 4 = 42¼ - 38¼ = (6½ + √38¼)(6½ - √38¼); thus, p = (6½ + √38¼), q = (6½ - √38¼).

To solve an equation, the goal is to get the variable by itself. In this case the variable is q. -6=8q-4 first you want to get 8q by itself because the 8 and the q are together right now. So add 4 to each side to cancel it out on the side that has a -4. -6+4=8q simplify. -2=8q then to get rid of the 8, you have to divide both sides by 8 and then you get q by itself. -2/8=q simplify again. -1/4=q q=-1/4 :)
