Answer:
4. 3x+1.8y
Step-by-step explanation:
(-3x+6.2y)-(-6x+4.4y)=-3x+6.2y+6x-4.4y=3x+1.8y
Answer:
49π
Step-by-step explanation:
Are of the circle equal π (where π is pi and "r" is the radius). Radius equals the diameter divided by 2. Therefore the area of this circle equals...
π = π = 49π
A/b times b/c is = ab/bc
which can be written as a/c times b/b
anything over itself is 1 so b/b is one
a/b times b/c = a/c
Answer:
She will get 1.52 back in change

She will get 1.52 back in change
A slope of zero means that the line is flat. In other words, change in "y" is equal to zero. Such an equation, using general representation of linear equation, is written as
y=mx+b but m=0
then, y=b
In the current scenario, b=-8
Therefore, the line equation is
y=-8
