For this case we have that the variable "x" represents the number of hours that Leticia uses to take care of children on Saturday.
IF on Friday I use 4 hours ($ 8 each) and on Saturday "x" hours ($ 8 each) obtaining a profit of $ 72, we have the following equation:

We apply distributive property:

So, on Saturday she spent 5 hours.
Answer:

It is not too difficult. Just do this
50-15
5(10-3)
The answer is 5(10-3)
Answer:
C
Step-by-step explanation:
original formula is: y - y1 = m (x - x1) ordinates= (x1, y1)
insert the a corresponding x and y coordinate:
y + 3 = -2 (x + 9)
Don't forget to change the signs depending on whether their positive or negative:
(3, -9) since 3 is positive but there is a minus in the formula it would be -3
since -9 is negative and in the equation there's a minus sign you would change it to positive. (negative times a negative equals a positive)
Answer:
Cube root of 1446
Step-by-step explanation:
The formula for the volume of a sphere is
. Therefore, if we divide 1928pi by 4/3pi and then take the cube root, you will find the radius. In this case, 1928pi/(4pi/3)=1446, meaning that the radius is the cube root of 1446. Hope this helps!
