Answer:

A. N and Q

Step-by-step explanation:

Look at the order of the triangles: MNL and PQR

MNL and PQR

They are both ordered in the middle, whereas others like M and Q are not. For example, M is ordered first and Q is middle.

N and Q match - The correct letters will always align in the order

Answer:

a. ∠N and ∠Q

Step-by-step explanation:

∠N and ∠Q are the pair of angle which are corresponding congruent angles as they have the same angles and matches with each other.

Answer:

1

Step-by-step explanation:

Given that both equations are equal, solve the distributive property and then just solve for X:

2x + 2(3x-1) = 3(x+1)
2x + 6x - 2 = 3x + 3
5x = 5
x = 1

Therefore, the value of X is 1.

To know the perimeter of the triangle, we apply the value of X to solve the equation.
3(x + 1)
3(1 + 1)
3 + 3 = 6.

Therefore, each figure's perimeter is 6, as both are equal.

x=-1

It has one solution, when y=0, x is - 1.

Eg. when, we substitute x= - 1 into the equation y=1x+1, y = 0

(1 x - 1 + 1 =0)

The solution on a graph will be at the point (-1,0)

Hope it helps ~

Step-by-step explanation:

Given that:

5(9 - x) + 3 = 23

Multiply the number outside of the bracket with numbers in the bracket on LHS.

⇛45 - 5x + 3 = 23

Shift constants from LHS to RHS, changing it's sign.

⇛-5x = 23 - 45 - 3

⇛-5x = 23 - 42

⇛-5x = -19

Shift the number 5 from LHS to RHS.

⇛x = -19/-5

Therefore, x = 19/5

Answer:

120

Step-by-step explanation:

the angle.of all of these is 180 and 35+25+X=180..

60+X=180...... X=120

The measure of angle D is equivalent to 120 degrees.

A triangle is a two - dimensional figure with three sides and three angles.

The sum of the angles of the triangle is equal to 180 degrees.

∠A + ∠B + ∠C = 180°

Given is that the measure of angle B is 25° and the measure of angle C is 35°.

For the triangle, we can write the measure of angle D as -

∠B + ∠C + ∠D = 180°

25° + 35° + ∠D = 180°

∠D = 180° - 60°

∠D = 120°

Therefore, the measure of angle D is equivalent to 120 degrees.

Answer:

65%

Step-by-step explanation:

Percent = (new price ÷ original price) x 100

             =  (48.75 ÷ 75) x 100

             = 65%

Therefore, $48.75 is 65% of the original price of $75.

The area of the triangle ABC is 81. 33 square units.

We have to determine

What is the area of triangle ABC?

The area of the triangle is determined by;

[tex]\rm Area \ of \ triangle = s\sqrt{s(s-a)(s-b)(s-c)}[/tex]

Where the value of s is = a + b + c= 12 + 14 + 16 = 42

Substitute all the values in the formula;

[tex]\rm Area \ of \ triangle = \sqrt{s(s-a)(s-b)(s-c)}\\\\\rm Area \ of \ triangle = \sqrt{21(21-12)(21-14)(21-16)}\\\\\rm Area \ of \ triangle = \sqrt{(21 \times 9 \times 7 \times 5)}\\\\Area \ of \ triangle =\sqrt{6,615}\\\\Area \ of \ triangle = 81.33[/tex]

Hence, the area of the triangle ABC is 81. 33 square units.

Answer:

$97.20

Step-by-step explanation:

he pays 90 dollars for the jacket

sales tax is 8% of the 90 dollars that he payed

so we can convert 8% to a decimal by moving the decimal 2 to the left. 8% to 0.08

now multiply 90*0.08 to find the sales taxes

90*0.08= 7.20

so we just add $7.20 to $90

and we get $97.20

we have: SM = TM

So: 2x + 3 = 4x - 7

=> 2x - 4x = -7 - 3

=> - 2x = - 10

=> x = (-10) / (-2) = 5

=> SM = 2 × 5 + 3 = 10 + 3 = 13
