Answers

Answer 1

Answer:

B: m∠1 + m∠3 = m∠2

Step-by-step explanation:

The sum of a triangle is 180° so all of the angles in the triangle are equal to 180°. It is not possible for 2 of the angles in a triangle to be equal to the other angle in the triangle.

Hope This Helps :)

Answer 2

Answer:

[tex]\huge\boxed{B}[/tex]

Explanation:

Hi there!

A) [tex]m\angle1 + m\angle3 = m\angle6\\[/tex]

B) [tex]m\angle1+m\angle3=m\angle2[/tex]

C) [tex]m\angle2+m\angle3=m\angle5[/tex]

D) [tex]m\angle1 + m\angle2 = m\angle4[/tex]

Let's start with a

How would [tex]m\angle1 + m\angle3 = m\angle6\\[/tex] ?

Well, [tex]m\angle1[/tex] and [tex]m\angle3[/tex] are inside the triangle, and [tex]m\angle6[/tex] is right across from it (see image provided with question), which means they are remote interior angles, meaning this statement is correct. A is not the answer.

How would [tex]m\angle1+m\angle3=m\angle2[/tex]?

There is no rule that 2 angles in a triangle have to add up to the other one, so this statement is incorrect. B is the answer. Let's make sure none of the others are incorrect as well.

How would [tex]m\angle2+m\angle3=m\angle5[/tex]?

Just like A, this is another case of remote interior angles, where [tex]m\angle2+m\angle3=m\angle5[/tex].  This option is correct due to this proof.

How would [tex]m\angle1+m\angle2=m\angle4[/tex]?

Another case of remote interior angles as you can see from the image, which means that this equation is correct.

The correct answer is B, as that is the only statement that is false.

plz tell me what y + 4 = ½ (x – 4) is in standard form of a linear equation this is my 3rd question about it i need it plz

Answers

Answer:

1/2x - y = 6

Step-by-step explanation:

First, distribute 1/2 to the parentheses:

y + 4 = ½ (x – 4)

y + 4 = 1/2x - 2

Then, subtract y from both sides:

4 = 1/2x - y - 2

Add 2 to both sides:

6 = 1/2x - y

Reorder the equation:

1/2x - y = 6 is the standard form of the equation

The first side of a triangle is 7 cm shorter than twice the second side. The third side is 4 cm longer than the first side. The perimeter is 90 cm. Find the length of all three sides.

Please answer! Im giving half of all my points!!

Answers

Answer:

first side = 33

second side = 20

third side = 37

Step-by-step explanation:

first side = 2x-7

second side = x

third side = (2x-7)+4

(2x - 7) + x + (2x - 7) + 4 = 90

5x - 14 + 4 = 90

5x - 10 = 90

     +10  +10

5x = 100

x = 20

first side:

2(20)-7

40 - 7 = 33

second side: 20

third side:

(2(20) - 7) + 4

(40 - 7) + 4

33 + 4 = 37

Step-by-step explanation:

Let's solve your equation step-by-step.

(0.6x)=

4

21

(0.25)

Step 1: Simplify both sides of the equation.

1.885714x=

21

Step 2: Divide both sides by 1.885714.

1.885714x

1.885714

21

1.885714

x=0.025253

The value of x from the given ratios 2 2/7 :(0.6x)= 4/21 :0.25 will be 5.

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

[tex]2 \frac{2}{7}[/tex] :(0.6x) = 4/21 :0.25

Therefore, solve the mixed fraction, we get

16/7 :(0.6x) = 4/21 :0.25

Step 1: Simplify both sides of the equation.

16/7 :(0.6x) = 4/21 :0.25

(16/7) / (0.6x) = (4/21 ) / (0.25 )

Step 2: Divide both sides

(16/7) / (0.6x) = (4/21 ) / (0.25 )

Cross multiply:

(16/7) x (0.25 )= (4/21 ) x (0.6x)

4/7 = 2.4x /21

84 = 16.8x

Divide both sides by 16.8:

x = 5

The sale price of an item is $160 after a 20% discount. What was the original price of the item?

Answers

Answer:

Answer:

The original price of the item is $200.

Step-by-step explanation:

Let the original price be 'x'.

The sale price of an item is $160 after a 20% discount.

i.e. original price - 20% of original price = $160

x-20/100x=160

x-0.2x=160

0.8x=160

x=160/0.8

x=200

Therefore, the original price of the item is $200.
