-1210
Basically you have two equations: xy = -1200 x + y = -10 Step 1: Solve one of these equations, for one of the variables (I suggest the first): xy = -1200 (xy)/x = (-1200)/x Divide both sides by x to get y by itself. y = -1200/x Step 2: Substitute the value of that variable into the other equation so that you are only dealing with one variable. x + -1200/x = -10 Step 3: Solve for X. x ( x - 1200/x) = (-10)x Multiply both sides by x to get rid of the fraction. x2 - 1200 = -10x x2 + 10x - 1200 = 0 Because this is a quadratic equation put all value on one side. (x + 40)(x - 30) = 0 Factor out the quadratic. x = - 40 or x = 30 Step 4: Plug this value(s) back into either original equations. x + y = -10 -40 + y = -10 y = 30 Step 5: If there is a second potential value, plug that back into the original equation. x + y = -10 30 + y = -10 y = -40 (This is the same answer as before just with x and y reversed so we can ignore) Step 6: Test answer. xy = -1200 (-40)(30) = 1200 TRUE x + y = -10 -40 + 30 = -10 TRUE -40 and 30 is the answer.
1 and 1200 2 and 600 3 and 400 5 and 240 6 and 200 8 and 150 10 and 120 12 and 100 15 and 80 16 and 75 20 and 60 24 and 50 25 and 48 30 and 40
For starters you have 120*5*2. There are a lot that I cannot mention them all
1200
That would be 0.98 x 1200 = 1176
1200
1200 is the only number that equals 1200.
12 and 100
1,000 milligrams equal 1 gram. Multiply 1200 grams by 1000. 1200 x 1000 = 1,200,000 mg
-1200 and -800, I thought at first, but I cannot think of 2 numbers possible. if 1200 is positive, 960000 has to be negative
To find 35 percent of a number, multiply the number by 0.35. In this instance, 0.35 x 1200 = 420. therefore, 35 percent of 1200 is equal to 420.
To find 29 percent of a number, multiply the number by 0.29. In this instance, 0.29 x 1200 = 348. Therefore, 29 percent of 1200 is equal to 348.
Multiply 600 by 2/3. 600 x 2/3, 600 x 2 = 1200, 1200/3 = 400.
To find 30 percent of a number, multiply the number by 0.3. In this instance, 4000 x 0.3 = 1200. Therefore, 30 percent of $4000 is equal to $1200.
To find 45 percent of a number, multiply the number by 0.45. In this instance, 0.45 x 1200 = 540. Therefore, 45 percent of 1200 is equal to 540.
To find 8 percent of a number, multiply the number by 0.08. In this instance, 0.08 x 15000 = 1200. Therefore, 8 percent of 15000 is equal to 1200.
1 and 1200 2 and 600 3 and 400 5 and 240 6 and 200 8 and 150 10 and 120 12 and 100 15 and 80 16 and 75 20 and 60 24 and 50 25 and 48 30 and 40
To find 8 percent of a number, multiply the number by 0.08. In this instance, 0.08 x 15000 = 1200. Therefore, 8 percent of 15000 is equal to 1200.
