<span>4.5
If you are told that two-thirds a number plus 4 is 7 and you wish to figure the number you can make an algebra formula: (2/3)X + 4 = 7
To simplify the formula you want to get the X alone. Begin by subtracting 4 from each side. (2/3)X + 4 - 4 = 7 - 4, so you now have (2/3)X = 3. To get the (2/3)X to be just 1X multiply each side by 3/2, so ((2/3)X)x(3/2) = 3x(3/2) giving you X=4.5</span>
Answer:
4(2-2c)
Step-by-step explanation:
because you switch it around
Neither! but if you round it , it will equal 8 and then it will be even
A² + b² = c²
11² + 9² = c²
121 + 81 = c²
202 = c²
√202 = c
14.2126704035518955 = c
Rounded 14.2126704035518955 ≈ 14.2
I hope this helps. (:
If half a gallon of milk is 3 dollars then you should be able to buy one gallon for 6 dollars. Therefore 5 dollars can buy 5/6 gallons of milk.
