Answer: 135°

Step-by-step explanation:

The sum of the interiors angles of the hexagone is (6-2)*180°=720°

Two angles are right: 2*90°=180°

The sum of the four angles is 720°-180°=540°

Each angle is  540°/4= 135°

Answer:

Answer:

Present age = 10

Step-by-step explanation:

Let us assume that,

→ Present age = x

Forming the equation,

→ x + 10 = 4(x - 5)

Now the value of x will be,

→ x + 10 = 4(x - 5)

→ x + 10 = 4x - 20

→ x - 4x = -20 - 10

→ -3x = -30

→ x = -30/-3

→ x = 30/3

→ [ x = 10 ]

Hence, the boy's age is 10.

Answer:

Is this a true or false question? Because nothing further can be done with the equation above. If so, the equation above is false.

Step-by-step explanation:

The area of any 2-d quadrilateral is equal to the base of the shape times the height, though we can just sub in length and width here. The key bits of information here is the aspect ratio (4:3) and the given area (300 in^2).

So far this gives us L∗W=300in2

Now, the aspect ratio given implies for every 4 inches in length, there will be 3 inches in width. This allows us to factor out a 4 and a 3 from the Length and Width respectively and give them the same constant variable, like so:

4x∗3x=300in2

Now, some might be tempted to go ahead with 12x here, but let’s expand the left side out to see what’s really going on:

4∗x∗3∗x=300in2

From here, let’s resolve like terms Our constants will multiply together and give us 12, and x * x of course gives us x^2 to give us the following:

12x2=300in2

From here, simply divide through by 12 to isolate x on one side,x2=25

And finally take the square root of both sides to work out what your common factor is,

x=5

Now that we have out common factor, let’s plug it back into our original formula to find our Length and Width, like so.

(4∗5)in∗(3∗5)in=300in2

20in∗15in=300in2

Therefore, the Length of our rectangle is 20in, and the Width of our rectangle is 15in

Answer:

Tessa's expression is false because -7 times -4 is positive 28, not -28.

Bernette's expressionis false because you must distribute the -7 before subtracting 7 from 2 (peMdas)

Lucy's expression is true because she correctly distributed the -7 to each of the terms in the parentheses and used PEMDAS.

2-21x+28

The equivalent expression for the given expression is 2-21x+28.

Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.

Tessa:

2-7(3x-4)=2-21x-28

Tessa's equivalent expression is wrong. Because -7×(-4)=28 not -28.

Bernette:

2-7(3x-4)=-5(3x-4)

Bernette's equivalent expression is wrong. Because, you can not 2 and 7, since 7 is multiplied to the term 3x-4

Lucy:

2-7(3x-4)=2-21x+28

Lucy's equivalent expression is correct.

Therefore, the equivalent expression is 2-21x+28.

Answer:

The answer is in the image! The interval notation is [-5,4)

Step-by-step explanation:

Notice that on the linee graph it shows a open circle on 4 and a closed dot on -5... This is because the number can be greater than -5 or equal to(this is represented by the brackets) and on 4 it can only be less than 4 and not equal to it (Represented by parenthesis)...

To solve for the inequality you must solve for x. The easiest way to do this is to multiply each component in the middlee by 3, the add two on both sides, then divide by 9 on both sides. This gives you the simplest inequality at -5<= x <4!

Answer: x=6+y/3

Step-by-step explanation:

3x=6+y

x=6+y/3

Equation of line is y = mx +b

Passing through (-3,7 )

X= -3, y= 7

plug in these

7 = -3m + b ... .Eq1

Also X = 4 , y= 10

10 = 4m + b ............... Eq 2

Solve Eq 1 and Eq 2 for m and b

m= 3/7

b= 58/7

Thus y =( 3/7) X + 58/7 is equation of line

0r 7y = 3X +58

Answer:

 x=17 degrees

m1=97 degrees

Step-by-step explanation:

     6x-19=3x+32(vertically opposite angles)

6x-19-3x=32

        3x =32+19

        3x=51

         x=17 degrees

   6x-19=83

   3x+32=83

if 1=y

83+83+Y+Y=360(points around a point is 360 degrees)

166+2Y       =360

      2Y       =360-166

              2Y=194

                Y=97

Therefore 1=97 degrees
