Let x=the number
2x=double the number
2x+5=the doubled number increased by 5
And we are told that this equals -47
sooooo
2x+5=-47 subtract 5 from each side2x=-47-5=-52
2x=-52
x=-26------the number
CK
2*(-26)=-52
-52 increased by 5=-52+5=-47
-47=-47

Answer:
width = 9 cm
Step-by-step explanation:
the area of a 12cm square is 144
16w = 144
x = 9
Since there is 16 cups in a US gallon, and there is 7 days in a week. First, you would multiply 1.5 times 7 getting 10.5 cups. But since that is not enough cups to be a gallon the division equation would look like this, 10.5/16 = ?. You can simplify it down to 5.25/8. Then, you get your answer of 0.65625 gallons.
The answer to that would be 39 x 4 = 156
