The equation is 18+2.50h=12+3.75h
The total cost of the services will be equal at 4.8 Hours
Set up a proportionality and simplify the fraction...hope this helps :)
Solve Let's solve your equation step-by-step.5+3.9x−8.15x25x=0
Step 1: Simplify both sides of the equation.−0.326x2+3.9x+5=0
Step 2: Use quadratic formula with a=-0.326, b=3.9, c=5.x=−b±sqrt(b2−4ac)2ax=−(3.9)±sqrt((3.9)2−4(−0.326)(5))2(−0.326)x=−3.9±sqrt(21.73)−0.652x=−1.1680135096973403,13.131203693746418Answer:<span>x=

Answer:
A.
Step-by-step explanation:
(The symbol with the two lines and the curved line over them means congruent.)
Answer:
B
Step-by-step explanation:
Each histogram section represents all values from the left value, to the right value of each section (i.e the section after 10 represents all values from 10 to 20).
If we break all the weights into categories by this principle, with frequencies in parenthesis, we get;
0-10: (0)
10-20: (0)
20-30: 21, 24 (2)
30-40: (0)
40-50: 42, 47 (2)
50-60: 54, 56 (2)
60-70: 65 (1)
70-80: 72 (1)
80-90: 83, 86 (2)
90-100: (0)
with these numbers, we know for certain that the correct answer is B
