4x+8=7.2+5x

Subtract 4x from both sides:
8=7.2+x

Subtract 7.2 from both sides:
0.8=x

x=0.8

4x+8=7.2+5x
subtract 7.2 from 8 and you get .8
subtract 5x-4x and you get 1x
therefore your answer is...
.8=x

Solve for y. 3(3y - 6) = 18

AveGali [126]

Answer:

y=4

Step-by-step explanation:

first you that the number outside of the parenthesis and multiply it by the numbers inside 3x3y (ignore the y for right now) and 6x3 now we have 9y-18=18 now we move the 18 so the y is by itself now we have 9y=36 divide both by 9 and you get your answer y=4

Y=-6x^2+100x-180

Hunter-Best [27]

In the figure we have the graphic of this equation. So, the vertex is the maximum of this function. This point means that the maximum daily profit from soccer balls is:

 $y = 236.67$

And this happens when the selling price of each soccer ball is:

 $x = 8.33$

So if you want to get the best daily profit, this is the price you must sell each soccer ball.

The transitive property holds true for similar figures. Always Sometimes Never

liubo4ka [24]

Answer: Always.

Step-by-step explanation:

The transitive property holds true for similar figures always because similar figures have similar shapes, the same angles and dimensions are proportional.

For example:- If figure 1 is similar to figure 2 then both have same shape and same angles and dimensions are proportional .

If figure 2 is similar to figure 3 then both have same shape and same angles and dimensions are proportional .

⇒ figure 1 is similar to figure 3 the both have same shape and same angles and dimensions are proportional as the figure 2 .

Thus the transitive property holds true for similar figures always.

The following are questions from a self-quiz.According to some study, the height for Northern European adult males is normally d

lara [203]

Answer:

a) 0.064

b) 0.109

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 181 centimeter

Standard Deviation, σ = 7.3 centimeter

We are given that the distribution of height for Northern European adult males is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

a) P(person is between 160 and 170 centimeters)

$P(160 \leq x \leq 170) = P(\displaystyle\frac{160 - 181}{7.3} \leq z \leq \displaystyle\frac{170-181}{7.3}) = P(-2.8767 \leq z \leq -1.506)\\\\= P(z \leq -1.506) - P(z < -2.8767)\\= 0.066 -0.002 = 0.064 = 6.4\%$

b) P(person is higher than 190 centimeter)

P(x > 190)

$P( x > 190) = P( z > \displaystyle\frac{190 - 181}{7.3}) = P(z > 1.2328)$

$= 1 - P(z \leq 1.2328)$

Calculation the value from standard normal z table, we have,

$P(x > 190) = 1 - 0.891 = 0.109 = 10.9\%$
