1/5x+ 1/3y would be the correct response.
Answer:
Step-by-step explanation:Perhaps somebody's asked this already, but I can't see it. Suppose I have a square that is 7 feet by 7 feet. I want to calculate the area. I multiply 7 feet by 7 feet and get 49 square feet, but since the lowest number of sig figs in one of my operands is one, my answer can only have one sig fig. This forces my answer to be 50 square feet, and I have now lost precision. Can somebody explain this?
2.3+8(1.3x-4.75)=629.9
2.3+10.4x-38=629.9
-35.7+10.4x=629.9
10.4x=665.6
x=64
The last step was --> D. Divide both sides of the equation by 10.4
It seems as though when the x value is multiplied by 7, you result in the y values (ex. 1*7 = 7). So you could say y = 7x.
Answer:
The answer is six.
Step-by-step explanation:
For a number to be divisible by nine means that the sum of the digits must be equivalent to a multiple of nine.
