So for example we have
1/2 divided by 1/6
What we will do it’s
Leave the first one As it is
Turn the second fraction (the one you want to divide by) upside down
The change the divide to multiply
Multiply the first fraction by that reciprocal
Simplify the fraction (if needed)
So it’s will be like this
1/2 x 6/1 = 6/2
Simplify it
6/2 =3
I hope it’s will help u ✨
Answer:

Step-by-step explanation:
The scientific notation:

We have:

Slope = (y2 - y1)/(x2 - x1) = (1 - 3)/(-2 - (-5)) = -2/(-2 + 5) = -2/3
For perpendicular lines, m2 = -1/m1 = -1/(3/8) = -8/3
A line passing through point (-4, 0) and parallel to the y-axis is x = -4

radius = diameter/2 = 10/2 = 5
center of circle = midpoint of diameter = ((-3 + 5)/2, (1 + 7)/2) = (2/2, 8/2) = (1, 4)
Required equation is (x - 1)^2 + (y - 4)^2 = 5^2
(x - 1)^2 + (y - 4)^2 = 25
10 * 10^2 - 7.79* 10^3
they have to be to the same power to add or subtract
change 10*10^2 to proper scientific notation (only 1 number before the decimal) 1*10^3
1*10^3 - 7.79*10^3 = (1-7.79) * 10^3=-6.79*10^3
Answer:
a. x=600
b. y=60
c. x = 150 and y = 45
Step-by-step explanation:
0.25x+2.50y=150
