If x = 4, solve this equation: 3x = ______? *

A. 14
B. 8
C. 16
D. 12

Answer:

AA ≅ AA postulate

Step-by-step explanation:

Given

[tex]A=(1,2)[/tex]

[tex]B = (3,5)[/tex]

[tex]C = (4,3)[/tex]

[tex]k = 3[/tex] --- scale factor

Required

Determine which statement that justifies the similarities between ABC and A'B'C'

When ABC is dilated by a scale factor of 3 to form A'B'C', the sides A'B'C are 3 times as large as the sides of ABC.

However, all three angles of both triangles remain the same. This is so, because dilation do not affect angles.

So, a statement that can be used to justify the similarities is:  AA ≅ AA

Answer:

i think y=3/4x-4.2

Step-by-step explanation:

Answer: 4x +10

Step-by-step explanation:

you just need to multiply the inside of the brackets by the outside so 2x x 2 = 4x and 5 x 2 = 10

Answer:

10 units

Step-by-step explanation:

Of course you have to graph the two points to find out the answer.

Then you count the units or squares to find out how far they are.

So it was basically 6 units to the right and 4 units up :)

x=2 3

x=8

Answer: the equation would be 5n=1,500

Step-by-step explanation:

5 dollars per N (student) they need to make 1,500 so you need to find n

( to find N do 1,500 divided by 5 = 300

Answer:

we thus have enough informnation to prove that the two triangles are congruent. Because of thism, one side of the triangles, Pm which is the congruent side to that of PQ must be equal as well and

PM = QM

Step-by-step explanation:

because it's a parrallelogram, Ad = BC and AB = DC.

P passes through both  AB and DC on a diagonal, angles created by P have oppoiste exterior angles of eachother.

the diagonals of AC create congruent angles at DMC and AMB and because P is cutting through them, the angles P cuts at DMQ and QMC are equal to that of AMP and PMB

that being said, we now see that the angles of APM triangle and AMC triangol are equal and because the diagonal of BD is is being cut by AC, which AD is parralel to BC  and AB to Dc, we know now that lines AM and MC are congruent

we thus have enough informnation to prove that the two triangles are congruent. Because of thism, one side of the triangles, Pm which is the congruent side to that of PQ must be equal as well and

thus PM = QM

The alternate interior angles formed by the parallel sides and a common

transversal are equal, such that ΔPBM and ΔQDM are congruent.

Step-by-step explanation:

formula for circle is pie X radius^2

Answer:

35.34

Step-by-step explanation:

The formula for arc length is 2rФπ/360

2(15)(135)=4050

4050/360·π=35.34

Step 1: Our output value is 350.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$350=100\%$.

Step 4: Similarly, $x=25\%$.

Step 5: This results in a pair of simple equations:

$350=100\%(1)$.

$x=25\%(2)$.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

$\frac{350}{x}=\frac{100\%}{25\%}$

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{350}=\frac{25}{100}$

$\⇒x=87.5$

Therefore, $25\%$ of $350$ is $87.5$

12x - 9y

Step-by-step explanation:

According to the distributive property:

3(4x - 3y) =

3*4x - 3*3y =

12x - 9y

Answer:

12x - 9y you can't subtract different variables so multiply by them both by the left over constant and get the expression of 12x - 9y

Step-by-step explanation:

50+(50/2)=

50+25= 75

(1/2 of 50 is 25)

Answer:

75 gallons

Step-by-step explanation:

Soooooo

they drank 50 gallons and then they drank half as much as they just drank

50/2 =25     -to get half of what they just drank

50 + 25 =75    - the original 50 gallons + half of that.
