It is: 7+w
100 7*w = number of days in w weeks.
n+7/6
x/4+7=-31
n+7 or X+7
2x + 7 = 15 Subtract 7 from both sides: 2x = 8 Divide both sides by 2: x = 4
2x + w = -w
100 7*w = number of days in w weeks.
w + 2.5 = 3.8
The number W
n+7/6
x/4+7=-31
n+7 or X+7
Call the number I am thinking of W ( for WikiAnswers) 2W+12=30 So 2W=18 W is 9 The number is 9
11
( 1 + 7x )
"4 times a number increased by 7" means you first take a number (let's call it ( x )), multiply it by 4, and then add 7 to the result. In mathematical terms, this can be expressed as ( 4x + 7 ). Essentially, you are scaling the number by 4 and then adding 7 to that scaled value.
The "answer" is usually the number that you can put in place of 'W'that will make the statement true.- 7/2 W = 20Multiply each side of the equation by 2:-7 W = 40Divide each side by -7 :W = - 40/7
