Answers

Answer 1

Answer:

Step-by-step explanation:

3x + y = 11

5x - y = 21

8x = 32

x = 4

3(4) + y = 11

12 + y = 11

y = -1

If m∠PTQ = 3y –10 and m∠QTR = y, find the value of y so that ∠PTR is a right angle

Answers

Answer:

y = 25

Step-by-step explanation:

Given that,

m∠PTQ = 3y –10 and m∠QTR = y

We need to find the value of y so that ∠PTR is a right angle.

For a right angle, one of the angle is 90 degrees. The sum of the angle of a triangle is equal to 180 degrees. So,

3y –10 + y + 90 = 180

Taking like terms together

3y+y = 180 -90 +10

4y = 100

y = 25

So, the value of y is 25.

If DE bisects <ABC.find the value of x if m<ABC=7x+29 and m<DBC=99°​

Answers

Answer:

19

Step-by-step explanation:

If DE bisects  <ABC, this means that <ABE = <EBC

Also <DBC+<EBC = 180

99+<EBC = 180

<EBC = 180-99

<EBC = 81

Also <ABC =<ABE+<EBC

<ABC =<EBC+<EBC

7x+29 = 81+81

7x = 162-29

7x = 133

x = 133/7

x = 19°

Hence the value of x is 19°

Answers

Answer: C. x=-8,14

Step-by-step explanation:

C

Answer:

              x = 14,  –8

Step-by-step explanation:

                 |x – 3| = 11

(x - 3) = 11                         - (x - 3) = 11

x - 3 = 11                           - x + 3 = 11

 x = 11 + 3                          -x  = 11 - 3

 x = 14                                  -x = 8

Answers

Answer:

9t²+(t²+2)

Step-by-step explanation:

The product of 9 and t squared is expressed as 9×t² (product means multiplication)

9×t² = 9t²

Also, sum of the square of t and 2" is expressed as t² + 2 (sum means addition)

Finally, if the product of 9 and t squared, increased by the sum of the square of t and 2", the final expression will be the sum of the two expressions gotten. {Increment also means addition} i.e 9t²+(t²+2)

The algebraic expression is 9t²+(t²+2)
