Answer:

x = 29

(x + 3)° = 32°

(x - 1)° = 28°

(x + 1)° = 30°

Step-by-step explanation:

  • (x + 3)° + (x - 1)° + (x + 1)° = 90°

  • -> (x + x + x +3 -1 + 1)° = 90°

  • -> (3x + 3)° = 90°

  • -> 3x + 3= 90

  • -> 3x = 90 - 3

  • -> 3x = 87

  • -> x = 87/3

  • -> x = 29

  • -> (x + 3)° = (29 + 3)° = 32°

  • -> (x - 1)° = (29 - 1)° = 28°

  • -> (x + 1)° = (29 + 1)° = 30°

Answer:

x=29

Step-by-step explanation:

The square notation indicates 90 degrees.

90=(x+3)+(x-1)+(x+1)

90=3x+3

87=3x

x=29

vovikov84 [41]

Answer:

Brandon is correct.

Step-by-step explanation:

Initially, there id 4 pints of green paint in the bucket.

As the green paint is made from equal amounts of yellow paint and blue paint, so, the initial amount of yellow and blue paint in the bucket  is 2 pint each.

Let x pints of yellow paint to be added to the bucket to make the desired shade.

Total amount of the paint in the bucket, after addition of x pints of yellow color become 4 + x pint, in which the ampunt of yellow color is 2+x pints.

As, the ampunt of yellow color is 80% of the total amount of the mixture, so

(4+x)\times 80\%=2+x

\Rightarrow (4+x)\times \frac{80}{100}=2+x

\Rightarrow 4(4+x)=5(2+x)

\Rightarrow x=6

So, 6 pints of yellow paint to be added to the bucket to make the desired shade.

Hence, Brandon is correct.

Answer:  c) 3

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

Plug in y = -9 and the given x-value to see if it makes a true statement.

a) -4.5 falls in the piecewise function x < -3  --> y = -x

y = -x

-9 = -(-4.5)

-9 = 4.5    FALSE

b) -3 falls in the piecewise function -3 ≤ x ≤ -2  --> y = 2x

y = 2x

-9 = 2(-3)

-9 = -6    FALSE

c) 3 falls in the piecewise function x > -2 --> y = -x²

y = -x²

-9 = -(-3)²

-9 = -9   TRUE

d) 9 falls in the piecewise function x > -2 --> y = -x²

y = -x²

-9 = -(9)²

-9 = -81   FALSE

Find the value of x, y, and z in the figure below:<br> ہ<br> 2y<br> IN<br> 2x<br> 90°<br> t
natima [27]

Answer:

x=30°

y=15°

z=150°

Step-by-step explanation:

2x+90+x=180°

2x=180°-90°

x=90/3

x=30

2y=x

y= 30/2

y=15°

2y°+z°=180°

2(15°)+z°=180°

z=180°-30°

z=150°

Hope it helps! :)
