Answer:

x=-10

Step-by-step explanation:

2(x-3)+7-3x=11

2\left(x-3\right)+7-3x-7=11-7

2\left(x-3\right)-3x=4

-x-6=4

-x-6+6=4+6

-x=10

\cfrac{-x}{-1}=\cfrac{10}{-1}

x=-10

Angle 1 and angle 2 form a linear pair.if m angle =5x+9 and m angle 2=3x+11,find the measures of both angels.
lbvjy [14]

Answer: ∠1 = 109°    ∠2 = 71°

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

If the two angles form a linear pair, then their sum is 180°

  ∠1      +     ∠2     = 180°

(5x + 9) + (3x + 11) = 180

              8x + 20  = 180

              8x          = 160

                x          = 20

∠1 = 5x + 9

    = 5(20) + 9

    = 100   + 9

    = 109

∠2 = 3x + 11

     = 3(20) + 11

     =    60  + 11

     =         71

  <u> CHECK:</u>

∠1   + ∠2 = 180°

109° + 71° = 180°

     180°   = 180°  \checkmark

IM GIVING OUT BRAINLIEST!!!<br><br> 9*8+2+4=_______
inn [45]

We use the Order of Operations here.

Parentheses

Exponents

Multiplying

Adding

Dividing

Subtracting (PEMDAS)

And if both are there, we work left to right.

In the process we multiply first, then add left to right..

So,

9 * 8 + 2 + 4

= 72 + 2 + 4

= 74 + 4

= 78.
