there's really no given answer. this kind of problem is usually answered by 'all whole numbers' or something like that because 'x' directly infulences the 'y' so, as i stated …before, no real given answer. (MORE)

Add 4x to each side: 2y = 4x + 8 Divide each side by 2: y = 2x + 4

The answer is 25. 5 x 25=125 Think about money. 125 cents = 5 quarters 1 quarter = 25 cents 5 x 25 = 125

y=3x is a direct variation in that y varies directly with x by a factor of 3. Any linear equation (a polynomial of degree 1, which is a polynomial equation with a highest expo…nent of 1), is a direct variation of y to x by some constant, and this constant is simply the coefficient of the "x" term. Other examples: y=(1/2)x is a direct variation, and the constant of variation is 1/2 y=-9x is a direct variation, and the constant of variation is -9 (MORE)

Use a calculator, and guess 2 numbers to see if it equals 125, if that doesn't work, use a sheet of paper, write down a math problem. For example: write 2 numbers and put …them the way you do to carry ones and all that. If that doesn't work either, ask an older brother or sister thats in highschool or college to ask them what equals 125. (MORE)

5c + 15= 30 - 15 -15 5c = 15 If your solving for just c..... 5c/5 = 30/5 c= 3 Hope this helps adding further your… question is incomplete you must ask for the value of C, since its a arithmetic equation. (MORE)

Figure out exactly what the equation means. 2x is the mathematical representation of "two times some unknown value" 2x + 3 = 17 means that "if you add 'two times some unkn…own value' and three, you get seventeen." To make a word problem for this equation, just represent that situation. For example: Jenny has twice as many shirts as Kendra does. When Jenny gets three more shirts for her birthday, she will have 17 shirts. How many shirts does Kendra have? (MORE)

125 + 125 + 125 + 125 + 125 + 125 = 125 * 6 = (100 * 6) + (20 * 6) + (5 * 6) = 600 + 120 + 30 = 600 + 100 + 20 + 30 = 700 + 50 = 750

So we have a statement that 3x + y = 7x = 2y. Can we find some values for x and y that will satisfy the statement? Suppose the statement is true, then we have 3x + y = 7x,… which yields y = 4x. or 3x + y = 2y, which yields y = 3x. Thus, 4x = 3x, if and only if x = 0, which also yields y = 0. Therefore, the given statement is true only for x = 0 and y = 0. For other values of x and y, it is a false statement. If there are two equations such as 3x + y = 7 and x = 2y, then substitute 2y for x into the first equation. 3(2y) + y = 7 6y + y = 7 7y = 7 y = 1, thus x = 2y = 2(1) = 2. Therefore the solution point is (2, 1), (MORE)
