=============================================================

Explanation:

Let's say x is the measure of angle 1, aka angle ABC. We'll also say the variable y is equal to angle 2, aka angle CBD.

Angles x and y add to angle ABD, which is 95 degrees

x+y = 95

Since angle 2 is four times that of angle 1, we also know that,

y = 4x

----------------

Let's apply substitution to solve for x

x+y = 95

x+4x = 95 ... replace y with 4x

5x = 95

x = 95/5

x = 19 which is the measure of angle 1

y = 4x = 4*19 = 76

x+y = 19+76 = 95 which helps confirm the correct answer.

The number 18 in the form of complex numbers will be written as 18 + 0i.

Every complex number may be represented in the form a + bi, where a and b are real numbers. A complex number is an element of a number system that extends the real numbers with a specific element labeled I sometimes known as the imaginary unit, and satisfies the equation i² = 1.

The given number is 18. The number in the form of a complex number can be written as:-

Complex number =  a + bi

Complex number =  18 + 0i

Therefore, the number 18 in the form of complex numbers will be written as 18 + 0i.

Answer:

3 miles per hour

Step-by-step explanation:

Well, what we do in these situations is simple. We divide.

So this George guy, he walks six miles in 2 hours.

I think to myself, "Okay, so that's 6 divided by 2."

So, we get 3.

#It'sNotRocketScience

if George walked 6 miles in 2 hours. Then his average walking rate in miles per hour is 3 miles per hour

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Given,

George walked 6 miles in 2 hours.

We need to find his average walking rate in miles per hour

Let x be the average walking rate in miles per hour

Let us form an equation

miles/hour----->6/2=x/1

3=x

So the value of x is 3

Hence if George walked 6 miles in 2 hours. Then his average walking rate in miles per hour is 3 miles per hour

Step-by-step explanation:

2(x+6)=4

2x+12=4

2x=4-12

2x=-8

x=-4

Answer:

x = -4

Step-by-step explanation:

First distribute 2 among everything in the parentheses. So now you'll have 2x + 12 = 4

Next subtract 12 on both sides to get -8.

Lastly divide 2 on both sides to get x = -4

Answer:

11

Step-by-step explanation:

44 dollars after 4 days so 44 divided by 4 = 11

Replace all occurrences of x with y + 3 in each equation.

Replace all occurences of x in 6x - 5y = 15 with y + 3.

6 (y+3) -5y = 15

x = y + 3

Simplify 6 (y + 3) - 5y.

Simplify each term.

Apply the distributive property.

6y + 6 · 3 - 5y = 15

x = y + 3

Multiply 6 by 3.

6y + 18 - 5y = 15

x = y + 3

Subtract 5y from 6y.

y + 18 = 15

x = y + 3

Move all terms not containing y to the right side of the equation.

Subtract 18 from both sides of the equation.

y = 15 - 18

x = y + 3

Subtract 18 from 15.

y = -3

x = y + 3

Replace all occurences with y with -3 in each equation.

Replace all occurences of y in x = y + 3 with -3.

x = (-3) + 3

y = -3

Add -3 and 3.

x = 0

y = -3

Answer: y=1/4x+4

Step-by-step explanation:

Parallel means the new equation will have the same slope.

y= 1/4x+b

We don't know the b value yet but we can plug in coordinates to solve. We can use the one provided since it has to be a value of this equation.

1= 1/4(-12)+b

1= -3+b

b= 4

Step-by-step explanation:

Uhh parallel lines are basically lines that have the same slope.

There are only three lines, lines m, n, and t

It can't be t because it's traversing lines m and n

so it has to be lines m and n

Answer:

y = 3x + 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x - 2 ← is in slope- intercept form

with slope m = 3

Parallel lines have equal slopes , then

y = 3x + c ← is the partial equation

To find c substitute (1, 5 ) into the partial equation

5 = 3 + c ⇒ c = 5 - 3 = 2

y = 3x + 2 ← equation of parallel line

Answer:

1.95

Step-by-step explanation:

We can use basic arithmetic to find the answer of your question through long division.

8.19/4.2 is basically 819/420, just multiplying both sides by 100 to get rid of the decimal point.

Using long division, we can subtract 420 from 819 to add 1 to the quotient and work with 399. Currently, our quotient is 1 with a remainder of 399

Since we can not get a positive number from 420-399, we must add a 0 to 3990 along with adding a decimal point to behind the 1. 420 can fit into 3990 9 times, so we add 9 after the decimal's point, and subtract 420*9=3780 from 3990, which is 210. Right now, our quotient is 1.9 with a remainder of 210.

Because we can not subtract 420 from 210 to get a positive number, we must add another 0 to 210 to get 2100. 420 can fit into 2100 5 times, so we remove 2100 from 2100, leaving no remainder. We also add 5 to the quotient, behind the 9. Now, our quotient is 1.95, the answer.
