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
w + 2.5 = 3.8
100 7*w = number of days in w weeks.
The number W
n+7/6
x/4+7=-31
n+7 or X+7
( 1 + 7x )
11
Call the number I am thinking of W ( for WikiAnswers) 2W+12=30 So 2W=18 W is 9 The number is 9
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
To express "7 times a number increased by 4" mathematically, you would write it as 7x + 4, where x represents the unknown number. This expression indicates that you multiply the number by 7 and then add 4 to the result. So, if the number is 5, the expression would be 7(5) + 4 = 35 + 4 = 39.
