Find the value of the unknown angle

Answer:

25

Step-by-step explanation:

4a +12 -2c + c

4( ) + 12 - 2( ) + ( )

4(4) + 12 - 2(3) + 3

16 + 12 - 6 + 3

28 - 6 + 3

22 + 3

25

Helping in the name of Jesus.

Therefore,  4a  +   12   -   2c   +   c  =   25

       a  =   4  

       c  =   3

        4a  +   12   -   2c   +   c

       (4)(4)  +  12  -     (2)(3)   +    3

         16     +   12   -   (2)(3)   +    3

         28      -            (2)(3)    +    3

         28     -   6     +     3

         22    +      3   =   25

Draw a conclusion:

     4a  +   12   -   2c   +   c   =  25

Answer:

B 5

Step-by-step explanation:

6x + 60 = 90 (right angle)

6x = 30

x = 5

Answer:

B.  5

Step-by-step explanation:

We can see that the two angles sum to 90°

⇒ 6x° + 60° = 90°

Subtract 60° from both sides:

⇒ 6x° + 60° - 60° = 90° - 60°

⇒ 6x° = 30°

Divide both sides by 6:

⇒ 6x° ÷ 6 = 30° ÷ 6

⇒ x = 5

Answer:

for the second one x = 34

Step-by-step explanation:

x + 23 = 57

subtract 23 on both sides

x + 23 - 23 = 57 - 23

x = 34

Answer:

c) 30%

Step-by-step explanation:

By dividing 20 up into 10, we get 2. Therefore, 10% of 20 is 2.

The price went from $20 to $14, a decrease of $6. Since 10% = $2, 30% would be $6.

So it was decreased by 30%

Answer:I think 30%

Answer:

0

Step-by-step explanation:

-2(4)/2 + 4

-2 * 4 = -8

-8/2 = -4

4 - 4 = 0

Answer:

$9.10

Step-by-step explanation:

you just need to multiply 6.50 by 2 and then take 30% off of it which is 9.10

Answer:

x = 36

Step-by-step explanation:

180 - 109 = 71 degrees

other angle is 39 degrees

39 + 71 = 110

180 - 110 = 70

70 - 34 = 36

x = 36

The angles of the triangle are (36+34) 70, 39, and 71 degrees, adding up to 180 degrees, which is correct.

The function for the points are  y = -15x - 5

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

y = -15x - 5.

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get

\(a=-15b-5\)

Answer:

To solve the equation -(x + 3) = 2(x - 3) for x, we can follow these steps:

Step 1: Distribute the negative sign on the left side of the equation:

-(x + 3) = 2(x - 3)

=> -x - 3 = 2(x - 3) (using the distributive property)

Step 2: Expand the right side of the equation:

-x - 3 = 2x - 6

Step 3: Add x to both sides of the equation to isolate the x term on one side:

-x + x - 3 = 2x + x - 6

=> -3 = 3x - 6

Step 4: Add 6 to both sides of the equation:

-3 + 6 = 3x - 6 + 6

=> 3 = 3x

Step 5: Divide both sides of the equation by 3 to solve for x:

3/3 = 3x/3

=> 1 = x

So, the correct value of x that makes the equation true is B. 1.

PLEASE MARK BRAILYISTT :D

Answer:

B, one

Step-by-step explanation:

In order to solve this, you can solve the equation. First, you can use the distributive property to get -x-3=2x-6. If you make the variables on one side and the constants on the other, you will get -3x-3=-6. This can further simplify to -3x=-6. Divide both sides by -3 to get that x=1. Then, the correct answer is B.

Answer: 76°

Step-by-step explanation:

Parallelograms have parallel sides.

That means AB || DC and AD || BC

We know ∠DAC is equal to 76° and by Alternate Interior Angles, ∠DAC ≅ ∠5.

Answer:

A/m=-2. since x goes up by 2 on the table, y decreases by 4 on the table, but if the next part of x on the table was 6, then y would be -2.

Irrational means it cannot be written as a fraction of two integers.

1/6 is a fraction, so that's out.

0.060606... can be written as a fraction because it's a repeating decimal, so that's out.

\(\sqrt{49}=7\) and 7 can be writen as the fraction 7/1, so that's out.

The answer is \(\sqrt{17}\).

Answer: 10 gallons

Step-by-step explanation: 40 divided by 4 is 10, apply same knowledge

Answer:

10 gallons of gas

Step-by-step explanation:

If John's car can travel 40 miles on 4 gallons of gas, then it can travel 10 miles on 1 gallon of gas.

To travel 100 miles, the car would need 100/10 = 10 gallons of gas.

Since it cost $30 for 4 gallons of gas, 1 gallon of gas would cost $30/4 = $7.50.

Therefore, it would cost 10 x $7.50 = $75 for the car to travel 100 miles.
