Alice is correct. If she multiplies the dividend and divisor by 4, the divisor becomes 1.
That one is true because if you multiply the divisor by 4, it becomes 0.25*4 = 1.
Of course, you can't multiply the divisor without multiplying the dividend.
So 15.5 / 0.25 = (15.5 * 4) / (0.25 * 4) = 62 / 1
And we know that if you divide a number by 1, the answer is that number.
so 62/1 = 62.
Which means that Alice found the quotient without even dividing based on Answer C.
Hope this helps! :)
Answer:
The equation of a line that is parallel to line a is y=½x + 2, or what is the same -½x+y-2=0
Step-by-step explanation:
A line is a polynomial function of the first degree that has the following form:
y = m * x + b
where m is the slope of the line and b is the intercept with the Y axis. The slope is the inclination of the line with respect to the abscissa axis.
In this case you know that the slope of line a is ½.
Parallel lines are two or more lines in a plane that never intersect. Two lines are parallel if they have the same slope and different y-intercepts.
You have:
- y+½x=2 → y= -½x +2
- -2x+y+2=0 → y=2x -2
- 2x-2=y
The line that has the same slope as line a is the last one, so <u><em>the equation of a line that is parallel to line a is y=½x + 2, or what is the same -½x+y-2=0</em></u>
If theres on at all then ~ C 6-8 however it seems that theres not one tbh
The answer is 10.8. You turn 10 4/5 into 54/5. Then you divide 54 by 5.
