Answer: z = 247.5

Step-by-step explanation:

4.8/2z+15=0.2/5 To eliminate the denominators, multiply both sides by their reciprocals.

2z(5)(4.8/2z+15)=2z(5)(0.2/5) Denominators "cancel." Distribute 5(4.8 + 15)

24 + 75 = 2z(0.2) Simplify: Add 24+75=99 and Multiply 2z×0.2= 0.4z

99 = 0.4z . Divide both sides by 0.4

99/0.4 = 0.4z/0.4 . 0.4 "cancels" on the right. dividing by a decimal is like multiplying by its reciprocal, 10/4 × 99

247.5 = z

Let x and y be two positive numbers whose sum is 175 and (x+3)(y+4) is a maximum

Vaselesa [24]

Answer:

Step-by-step explanation:

x+y = 175

y = 175 - x

f(x) = (x+3)(y+4)

= x(175-x) + 3(175-x) + 4x + 12

= 175x - x² + 525 - 3x + 4x + 12

= -x² +176x + 537

f'(x) = -2x + 176

maximum when x = 88

y = 175-x = 87

patriot [66]

Step-by-step explanation:

3 + 4 + 5 + 6 + 6 + 7 + 8 + 8 + 9 + 9 / total of numbers or 10 = 65 ÷ 10 = 6.5 This is the mean.

3 - 6.5 = 3.5

4 - 6.5 = 2.5

5 - 6.5 = 1.5

6 - 6.5 = 0.5

7 - 6.5 = 0.5

8 - 0.5 = 7.5

9 - 0.5 = 8.5
