120-95=c is the best way

Hey there!

<h2>ANSWER: $x=2$ </h2><h2>EXPLANATION:</h2>

$5x-3x=6x-8$

Combine like terms.

$(5x+-3x)=6x-8\\2x=6x-8$

Subtract 6x from both sides of the equation.

$2x-6x=6x-8-6x\\-4x=-8$

In the last step, we will divide both sides by -4.

$\frac{-4x}{-4} =\frac{-8}{-4} \\x=2(ANSWER)$

Hope this helps and have a great weekend!

Dvinal [7]

Step-by-step explanation:

Since m∠ACM = 90°, then by angle addition, m∠ACP + m∠PCM = 90°.
Since CP⊥ AM, then by definition of perpendicular, m∠APC = 90°. Since angles of a triangle add up to 180°, that means m∠PAC + m∠ACP = 90°.
By substitution, m∠PCM = m∠PAC.
Since m∠PCM + m∠CMP = 90°, then by substitution, m∠CMP = m∠PAC.
Therefore, by AAA, △ACP and △CMP are similar.

Having proven that the triangles are similar, we can write the proportion:

AP / CP = CP / MP

9 / CP = CP / 16

CP² = 144

CP = 12

Now, we can simply use Pythagorean theorem to find the other sides.

AC² = AP² + CP²

AC² = 9² + 12²

AC = 15

CM² = CP² + PM²

CM² = 12² + 16²

CM = 20

The line representing a proportional relationship always goes through the point (0,0). If x is zero, multiplying x by the consta

Sidana [21]

Answer:

B (2, 4)

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $k=\frac{y}{x}$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

In this problem the constant of proportionality k is given and is equal to

$k=2$

so

The linear equation is given by

$y=2x$

That means ----> the y-coordinate is two times the x-coordinate

therefore

The other point is B(2.4)

Because

For x=2, y=4

the y-coordinate is two times the x-coordinate

$4=2(2)\\4=4$

Jack's last six scores are 75,78,83,80,79,84. If he scores a 90 on the next test, by how much will his mean test score increase?

kondaur [170]

Answer:

1.46

Step-by-step explanation:

First find the the mean score before he made a 90.

$\frac{75+78+83+80+79+84}{6} = 79.83$

Now add the score of 90 and calculate.

$\frac{75+78+83+80+79+84+ 90}{7} = 81.29$

Subtract the two scores.

$81.29-79.83 = 1.46$

His mean test score increased by 1.46.
