hol up
Step-by-step explanation:
Answer:
We have the equation
we leave the terms with x on the left side of the equation and the independent terms on the right side.
resolving for x we have that
Since we need that the equation doesn't have solution, then it is necessary that the denominator of x be 0 and this occur when
Then, for the equation hasn't solution
Answer:
175
Step-by-step explanation:
A glass and a half is 1+1/2 = 3/2 glasses.
2 1/2 glasses is 2/2 glasses more than that, or 5/2 glasses.
5/2 glasses is 5/3 times the size of 3/2 glasses, so there will be 5/3 the number of calories:
... (105 calories) × (5/3) = 175 calories

Answer:
1.98 × 10^10
Step-by-step explanation:
First solve for how many text messages were sent out per one month:
22,000,000 × 900
19,800,000,000
Convert into scientific notation:
1.98 × 10^10
In scientific notation, there can only be one number before the decimal. The rest of the numbers must be after the decimal; hence, why I put the numbers 9 and 8 after the decimal. If the rest of the numbers are zeros, you do not have to add them after the decimal. Instead, starting from right to left, count the number places until you reach your decimal. The number you have counted will be your exponent. I counted nine 0's, one 8, and one 9 which made this exponent 10 as there were 10 decimal placements.
