There is a number such that three times that this number minus 6 is equal to 45

Let "the number" = x

3x - 6 = 45 is your equation

Solve for x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

Isolate the x. First, add 6 to both sides

3x - 6 (+6) = 45 (+6)

3x = 51

Isolate the x. Divide 3 from both sides

3x/3 = 51/3

x = 51/3

x = 17

17 is your answer for "a number".

hope this helps

i believe the answer is 68cm

step-by-step explanation:

i just took 34 x 2 because the space between v and y is the same as y to k.

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
