Answer:

30

Step-by-step explanation:

Right angle = 90 degrees

180-90 = 90, hence the right side of the equation.

x+37+x+67 = 90

2x + 104 = 90

2x = -14

x = -7

Plug in x.

-7+37 = 30 (angle a)

Angle a  = 30

Answer:

angle A = 30 degrees

Step-by-step explanation:

*All triangles have an interior angle that adds up to 180 degrees

The triangle is the picture is a right triangle so one of the angles is 90 degrees.

First, we must figure out what "x" is:

⇒ 180 = 90 + x + 37 + x + 67

Combine like terms:

⇒ 180 = 2x + 194

Subtract 231 from both sides:

⇒ 180 - 194 = 2x + 149- 194

⇒ -14 = 2x

The divide both sides by 2:

⇒ [tex]\frac{-14}{2} + \frac{2x}{2}[/tex]

⇒ -7 = x

Now, we can figure out what angle A is by taking the equation "x + 37" and subtituting x by -7:

⇒ x + 37

⇒ -7 + 37

⇒ 30

To check out answers, take all of the eqautions in the picture and subtitute x by -7, (remember that it must add up to 180):

⇒ 90 + x + 37 + x + 67 = 180

⇒ 90 + (-7) + 37 + (-7) + 67 = 180

⇒ 180 = 180

Answer:

Length=2(x-1)

Width=5

Area=length*width = (2(x-1))(5) = (2x-2)(5) = 10x-10

29

His reasoning is illogical because whether or not an expression has a term that is being subtracted isn't relevant; technically there are an infinite amount of ways to represent a value. Plus you can just compute the expressions and see that they're equal:

6x-2x+4 = 4x+4

4(x-1) = 4x+4

30

The two expressions are equal because when you compute the expression 4(n+3)-(3+n) , you get 3n+9:

4(n+3)-(3+n) = 4n+12-3-n = 3n+9

31

The two expressions are equal because when you compute the expression 2(2n-1), you get 4n-2.

2(2n-1) = (2)(2n)+(2)(-1)=4n-2

32

5(g+14)=(5)(g)+(5)(14)=5g+70

The expressions aren't equal as 5(g+14) equates to 5g+70 and 5g+70≠5g+14.

Answer:

$27.2

Step-by-step explanation:

A cake that costs $32 is on sale for 15% off and there are no taxes. Explain why the expression (0.85).32 represents the final price of the cake in dollars.

This is explained in the calculation below

= A cake that costs $32 is on sale for 15% off

The amount off the cake is calculated as

= 15% of $32

= 15/100 × 32

= $4.8

The amount he is paying for the cake =>$32 - $4.8

= $27.2

The above expression is obtained as

(0.85).32

= (100% - 15%) × 32

=( 1 - 0.15) × 32

= 0.85 × 32

= $27.2

The final price of the cake = $27.2

Answer: 50°

Step-by-step explanation:

Since angle 3 is in a right triangle we can assume one angle is 90° and then the other missing angle will be 40°

Because you take 180°-140°(the angle next to it) which will equal 40°

Now every triangle must add up to 180°

so lets take the angles we have now

90° +40°=130°

now take that 130°

180°-130°=50°

Now check your work

90°+40°+50°=180°

Angle 3 is 50°

Answer:108

Step-by-step explanation:

Answer:

she walks about 145.7 meters in 5 minutes

Step-by-step explanation:

Hey There!

so first we want to find the meters per second rate

to do this we do

[tex]\frac{12}{24.7} = 0.48582995951[/tex]

so the meters per second is 0.4858299591

Then we want to find how many seconds are in a 5 minutes

to do this we multiply 5 and 60

5x60=300

then we want to multiply that by the meters per second

300x 0.4858299591=145.748987854

so she walks about 145.7 meters in 5 minutes

Answer:

$1,560

Step-by-step explanation:

6% of $750 = $45

$45 times 18 = $810

$810 + $750 = $1,560

So we're going to debunk this phrase.

4 more means we're adding 4 somewhere. product is the answer to a multiplication problem, so we have to multiply 8 and n. Because n is a variable, we're going to write it as 8n.

So the expression would be 8n+4.

Answer:

250 in.

Step-by-step explanation:

SA= 2(LW+LH+WH)

= 2(10*5+10*5+5*5)

Answer:

23.7°

Step-by-step explanation:

To obtain the value of AB ; Use the cosine rule ;

Recall:

c² = a² + b² - 2ab Cos C

c² = 24² + 11² - 2*24*11 Cos75

c² = 576 + 121 - 528 * 0.2588190

c² = 697 - 136.656432

c² = 560.343568

c = sqrt(560.343568)

c = 23.6715

Hence, c = AB = 23.7°
