Answer: x = 3.5

Step-by-step explanation:

We can start by subtracting 5 from both sides:

2x - 5 = 12 - 5      Which will come out to: 2x = 7

Then we divide both sides by 2 so that we can isolate the variable:

2x/2 = 7/2       Which will come out to: x = 3.5

Answer: 128 degrees

Step-by-step explanation:

If m1 = 27° and m2 = 25°, what is m3?

27+25=52

180-52=128

that's the simplest way to do it

The measure of m₃ will be;

⇒ m₃ = 128°

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

In a triangle;

⇒ m₁ = 27°

⇒ m₂ = 25°

Now,

We know that;

In a triangle, The sum of all interior angle is equal to 180°

Hence, We get;

⇒ m₁ + m₂ + m₃ = 180°

⇒ 27° + 25° + m₃ = 180°

⇒ m₃ = 180 - 52°

⇒ m₃ = 128°

Thus, We get;

⇒ m₃ = 128°

Seven subtracted by a number

Step-by-step explanation:

A verbal expression is a mathematical statement that is expressed in words.

Answer:

∠AMC = 76°

Step-by-step explanation:

1) Because ∠YMC = 170°, you need to add 5x+19 (∠YMA) and 5x+1 (∠AMC) to equal the length of ∠YMC:

170 = 5x + 19 + 5x + 1

2) Combine like terms:

170 = 10x + 20

3) Subtract 20 from both sides:

150 = 10x

4) Divide by 10:

x =15

5) Replace x in ∠AMC with 15:

5(15) + 1

6) Multiply:

∠AMC = 76°

The measure of ∠AMC is 76°.

Given that, m∠YMC=170°, m∠YMA=(5x+19)° and m∠AMC=(5x+1)°.

We need to find the value of m∠AMC.

The two angles are said to be adjacent angles when they share the common vertex and side. The endpoint of the rays, forming the sides of an angle, is called the vertex of an angle. Adjacent angles can be complementary angles or supplementary angles when they share the common vertex and side.

Now, m∠YMA+m∠AMC=m∠YMC

⇒(5x+19)° + (5x+1)°=170°

⇒10x+20=170

⇒10x=150

⇒x=15

So, m∠AMC=5x+1=76°

Therefore, the measure of ∠AMC is 76°.

$354.19

Step-by-step explanation:

The total payment was $380.75 plus 7.5% of that, which can be represented by

(1 + 0.075)r = $380.75, where r is the repair bill before taxes.  Then:

1.075r = $380.75, and r = $354.19 (rounded to the nearest cent)

Answer:

Function A has  

✔ no slope

.

The equation of line A is  

✔ x = -5

.

Function B has  

✔ a slope of 0

.

The equation of line B is y= -5

Step-by-step explanation:

i did the online assighnment

The true expressions about functions A and B from the options given are :

Function A :

Points: (–5, –2), (–5, 7)

Slope = (7 - (-2)) ÷ (-5 - (-5)) = 9 ÷ 0 = 0

From :

We can obtain c, thus ;

-2 = 0(-5) + c

-2 = c

y = - 2

Function B :

Points:(7, –5), (–2, –5)

Slope = (-5 - (-5)) ÷ (-2 - 7) = 0 ÷ - 9= 0

From :

b = slope ; c = intercept

We can obtain c, thus ;

-5 = 0(7) + c

-5 = c

y = -5

Answer:

b = -1

Step-by-step explanation:

use distributive property to multiply the -2 with the numbers in the parentheses

3 - 2b + 4 = 2 - 7b

7 - 2b = 2 - 7b

add 2b to both sides

7 = 2- 5b

subtract 2 from both sides

5 = -5b

divide by -5

b = -1

The solution for b is -1.

Let's solve the equation step by step to isolate the variable b:

3 - 2(b - 2) = 2 - 7b

First, simplify the expression inside the parentheses:

3 - 2b + 4 = 2 - 7b

Combine like terms:

7 - 2b = 2 - 7b

Next, let's isolate the terms with b on one side. We can do this by adding 7b to both sides:

7 - 2b + 7b = 2 - 7b + 7b

Simplifying:

7 - 2b + 7b = 2

Combine like terms:

7 + 5b = 2

Now, let's isolate the term with b by subtracting 7 from both sides:

7 + 5b - 7 = 2 - 7

Simplifying:

5b = -5

Finally, solve for b by dividing both sides by 5:

(5b) / 5 = (-5) / 5

Simplifying:

b = -1
