Answer:
5 hours
Step-by-step explanation:
Step one:'
given data
Angelo charges a one time fee of $50 plus $15 per hour
let the total charge be y
and the number of hours be x
y= 50+15x----------------1
Deborah charges a one time fee of $25 plus $20 per hour
y= 25+20x----------------2
equate 1 and 2 to find x
50+15x=25+20x
collect like terms
50-25= 20x-15x
25= 5x
divide both sides by 5
x= 25/5
x= 5 hours
Answer:
x > - 
Step-by-step explanation:
Given
6(x + 1) > 2x - 1 ← distribute parenthesis on left side
6x + 6 > 2x - 1 ( subtract 2x from both sides )
4x + 6 > - 1 ( subtract 6 from both sides )
4x > - 7 ( divide both sides by 4 )
x > -
Change the equation, x - y = -3, to isolate x or y and plug that new equation into the equation 2x + 3y = 4
I changed it to: x = y - 3
so
2(y - 3) + 3y = 4
2y - 6 + 3y = 4
5y - 6 = 4
5y = 4 + 6
5y = 10
y = 10/5
y = 2
then you plug that 2 into the equation x = y - 3 to get the value of x
x = (2) - 3
x = -1
you can check this by plugging the x and y values into the equation 2x + 3y = 4
2(-1) + 3(2) = 4
-2 + 6 = 4
4 = 4
hope this helps :)
You shouldn’t need radius but the area is 46
you make the thing hanging of a square and the other big shape a triangle then 2x3 is 6 and 8x10 decided by 2 is 40 and 40+6 is 46
