Hey there, we need to find a red marble, there are three red marbles, so we need to make a fraction, 3 is the denominator. Now, we need to add up all of the marbles and that will be our numerator, 4+3+3=10. So, the fraction would be 3/10, Therefore, the answer is D. 3/10
Eloise made these steps well:
Square root of negative 2x plus 1 - 3 = x
Square root of negative 2x plus 1 - 3 + 3 = x + 3
The error comes in the next step:
Square root of negative 2x plus 1 = x + 3
Square root of negative 2x plus 1 -1 = x + 3 - 1
Square root of negative 2x = x + 2
the number one is inside the root, therefore they can not be subtracted.
answer
error in the step:
Square root of negative 2x = x + 2
Option one for the first question would be best because it is 2500 greater. Option 1 is 80000 while option 2 is only 77500.
2x=y where 2 is dollars per tomatoe, x is amount of pounds of tomatoes, and y is amount of money spent in total. say you got 3 pounds of tomatoes; the equation would be 2(3)=y. y=6. Hope I helped!
