Answer:

x = 65.4

Step-by-step explanation:

Formula For Cos: cos (x°) = adjacent/hypotenuse

Adjacent = 5

Hypotenuse = 12

cos (x) = adjacent/hypotenuse

cos (x) = 5/12

x = cos⁻¹ (5/12)

x = = 65.3756816478359

x = 65.4 (rounded)

Tip: cos⁻¹ is inverse of cos.

Therefore, x = 65.4

16d + 5 = -10
what is d?

Answers

Answer:

d  = -15/16

Step-by-step explanation:

To solve for D, you have to get D alone on one side of the equation (one side of the equal sign).

So get rid of the other numbers that are being added or subtracted to d first. To do that, you have to do the opposite of what is being done.

So u have +5 on the left, you have to minus it to get rid of it. Whatever you do on one side of the equation, you have to do to the other side

so 16d +5 minus 5 = -10  minus 5

the 5 cancels out on the left   and -10 - 5 = -15

now you have 16d = -15

Now you have to get rid of the 16. It's being multiplied to d so to do opposite is to divide it by 16. And whatever you do on one side, u have to do on the other.

16d divided by 16 = -15 divided by 16

16d/16 = d       -15/16  

So d = -15/16

For the expression, value of d is,

⇒ d = - 15/16

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ 16d + 5 = - 10

Now, We can solve the expression as;

⇒ 16d + 5 = - 10

Subtract 5 from both side;

⇒ 16d + 5 - 5 = - 10 - 5

⇒ 16d = - 15

Divide by 16 both side;

⇒ d = - 15/16

Therefore, For the expression, value of d is,

⇒ d = - 15/16

Step-by-step explanation:

what is 4855/200 simplified

Answers

Answer:

The answer is 2427.5

Step-by-step explanation:

The fraction consists of two numbers and a fraction bar: 4,855/200

The number above the bar is called numerator: 4,855

The number below the bar is called denominator: 200

The fraction bar means that the two numbers are dividing themselves.

To get fraction's value divide the numerator by the denominator:

Value = 4,855 ÷ 200

To calculate the greatest common factor, GCF:

1. Build the prime factorizations of the numerator and denominator.

2. Multiply all the common prime factors, by the lowest exponents.

Factor both the numerator and denominator, break them down to prime factors:

Prime Factorization of a number: finding the prime numbers that multiply together to make that number.

4,855 = 5 × 971;

4,855 is a composite number;

In exponential notation:

X = -7
4x - 4y = 12
Submit

Answers

Answer:

Point Form:

( − 7 , − 10 )

Equation Form:

x = − 7, y = − 10

Step-by-step explanation:

Solve for the first variable in one of the equations, then substitute the result into the other equation.

Answer:

y = -10

Step-by-step explanation:

4x - 4y = 12

Substitute the x with -7, since it has been given.

4(-7) - 4y = 12

-28 - 4y = 12

Add 28 onto both sides

-28 + 28 - 4y = 12 + 28

-4y = 40

Divide by -4 to isolate the variable

-4y/-4 = 40/-4

y = - 10

Check:

Substitute the y and x

4x - 4y = 12

4(-7) - 4 ( -10 ) = 12

-28 + 40 = 12

12 = 12

or.....

try to see if x stays as -7

4x - 4y = 12

4x - 4 (-10) = 12

4x + 40 = 12

Subtract 40 onto both sides

4x + 40 - 40 = 12 - 40

4x = -28

Divide by 4 onto both sides to isolate the variable

4x/4 = -28/4

x = -7

And it's correct

Hope this helped!

Answers

Answer:

x = 52

m<ACD = 159

m<ACB = 21

Step-by-step explanation:

1) Set up an equation.

2x + 55 = 3x + 3 (the two interior angles on the opposite of the triangle and the exterior angle are equal to the exterior angle)

2) Solve for x.

2x + 55 = 3x + 3

-x + 55 = 3

-x = -52

x = 52

3) Substitute 'x' into each angle required to find m<ACD and m<ACB.

m<ACD = 3(52) + 3

= 156 + 3

= 159

CHECK:

2(52) + 55 = 159

104 + 55 = 159

159 = 159

m<ACB + m<ACD = 180

m<ACB + 159 = 180

m<ACB = 21
