The answer is 78 for that question

If triangle MNP is congruent to triangle QST, that means that M and Q are congruent, N and S, and P and T, as they are in order, respectively.  This means that the measure of angle S is the same as the measure of angle N, which is 78º.  Therefore, the measure of angle S is 78º.  

Hope this helps!

9. Factorize: 6x2 - 19x + 14.​
Stella [2.4K]

Answer:

Step-by-step explanation:

Here, we want to factor the given polynomial

We have this as;

6x^2 - 19x + 14

= 6x^2 -12x-7x + 14

= 6x(x-2) -7(x-2)

= (6x-7)(x-2)

6x^2-19x + 14 = (6x-7)(x-2)

Which statement is sometimes true:
Lelu [443]

Answer:

4. A rectangle is a square

Step-by-step explanation:

A rectangle can be a square, but not always. A rectangle has 2 pairs of parallel sides, 2 pairs of congruent sides, and 4 right angles. Squares have 2 pairs of parallel sides, 4 congruent sides, and 4 right angles. So, the difference between the two is that adjacent sides are not necessarily congruent in rectangles, but they are in squares. This means that some rectangles can be a square. If a rectangle has all congruent sides, then it is a square. On the other hand, some rectangles do not have all congruent sides, and thus are not squares.

Students are given 3 minutes to complete each multiple-choice question on a test and 8 minutes for each free-response question.
SpyIntel [72]

Let

x------> the number of multiple choice question

y------> the number of free response question

we know that

3x+8y=55 -----> equation A

x+y=15

x=15-y -----> equation B

Substitute equation B in equation A

3[15-y]+8y=55

45-3y+8y=55

5y=55-45

5y=10

y=2

Find the value of x

x=15-y

x=15-2=13

therefore

<u>the answer is</u>

the number of multiple choice question are 13

the number of free response question are 2

A store sells televisions for $360 and DVD burners for $270. The entire stock is worth $52,920 and there are a total of 164 tele
bogdanovich [222]

Answer:  96 Televisions, 68 DVD burners

<u>Step-by-step explanation:</u>

Let T represent the quantity of televisions

Let D represent the quantity of DVD burners

<u>Given:</u>

value of television (T) = 360

value of DVD burners (D) = 270

Total value = 52,920

<u>Equations:</u>

Value: 360T + 270D = 52,920

Quantity:   T + D = 164

We can solve the system of equations using the Elimination Method:

-1(360T + 270D = 52,920) →  -360T - 270D = -52,920

  360(T + D = 164) →                <u>360T + 360D</u> = <u>59,040 </u>

                                                                90D = 6,120

                                                              <u> ÷90   </u>  <u> ÷90    </u>

                                                                     D = 68

Input the value of D into one of the equations to solve for T

T + D = 164

T + 68 = 164

      T   = 96
