[ Answer ]

\boxed{X \ = \ 57}

[ Explanation ]

\frac{1}{3}(3x + 9) = 60

Multiply Both Sides By 3:

3 · \frac{1}{3}(3x + 9) = 60 · 3

Simplify:

3x + 9 = 180

Subtract 9 From Both Sides:

3x + 9 - 9 = 180 - 9

Simplify:

3x = 171

Divide Both Sides by 3:

\frac{3x}{3} \ = \ \frac{171}{3}

Simplify:

X = 57

\boxed{[ \ Eclipsed \ ]}

dlinn [17]

Answer:

New value =

39 - Percentage decrease =

39 - (3% × 39) =

39 - 3% × 39 =

(1 - 3%) × 39 =

(100% - 3%) × 39 =

97% × 39 =

97 ÷ 100 × 39 =

97 × 39 ÷ 100 =

A teacher summarizes grades on an exam by,Min = 26, Q1 = 67, Q2 = 80, Q3 = 87, Max = 100, Mean = 76, Mode = 100, Standard deviat
chubhunter [2.5K]

we have

Min=26

Q1=67

Q2=80

Q3=87

Max=100

Mean=76

Mode=100

standard deviation=76

IQR=20

so

In this problem

the mean is equal to the standard deviation

therefore

<h2>The standard deviation is incorrectly</h2>

Umnica [9.8K]

Answer:

Julio debe $ 41225 al banco por concepto del préstamo para invertir en su casa.

Step-by-step explanation:

Dada la falta de información, asumimos que el préstamo fue realizado sin tasa de interés, de modo que la deuda solo sea el monto inicial menos las cuotas pagadas por quien recibe el préstamo, la cantidad de dinero que adeuda al banco es:

x = \$\,100000 - \$\,32950 - \$\,25825

x = \$ \,41225

Julio debe $ 41225 al banco por concepto del préstamo para invertir en su casa.

Find the value of x that maximized the volume of the following:
Shtirlitz [24]

Check the picture below.

as you can see, the graph of the volume function comes from below goes up up up, reaches a U-turn then goes down down, U-turns again then back up to infinity.

the maximum is reached at the close up you see in the picture on the right-side.

Why we don't use a higher value from the graph since it's going to infinity?

well, "x" is constrained by the lengths of the box, specifically by the length of the smaller side, namely 5 - 2x, so whatever "x" is, it can't never zero out the smaller side, and that'd happen when x = 2.5, how so? well 5 - 2(2.5) = 0, so "x" whatever value is may be, must be less than 2.5, but more than 0, and within those constraints the maximum you see in the picture is obtained.

Factor out the greatest common factor. 10a3b−6a2b2
podryga [215]

Answer:

2a^2b(5a-3b)

If not then the other way is

5a-3b

Step-by-step explanation:

The GCF of 10a^3b and -6a^2b^2 is 2a^2b

So divide by that you will get

2a^2b(5a-3b)
