Answer:

Line s and Line t are parallel.

Step-by-step explanation:

Now, we know that angles 1 and 2 are congruent, because they have the same angle measures. Now, looking at their positions, we can see that they are alternate exterior angles.

By the converse of the Alternate Exterior Angle, (I do not remember exactly how the theorem went) if two lines are cut by a transversal and have congruent alternate exterior angles, then the lines are parallel. Using this theorem, we can find that lines s and t are parallel, because they are cut by a transversal and their alternate exterior angles are congruent.

Step-by-step explanation:

Answer:

y = -1/4x + 4

Step-by-step explanation:

x+4y=28

4y = -x + 28

y = -1/4x + 7

slope m = -1/4

Parallel lines have similar slope so we'll use -1/4 from above and given point (8,2) to find y-intercept.

y = mx +b

2 = -1/4(8) + b

2 = -2 + b

b = 4

Using m and b from above we can now form the new equation of line that is parallel to y = -1/4x + 7.

y = mx + b

y = -1/4x + 4

Answer:

$0.15

Step-by-step explanation:

Given problem:

What is the value of x = ?

 Solution:

Angle on a straight line is 180°

Sum of angles in a triangle  = 180°

Now to solve the problem, we need to find the two internal angles first;

  For the first one;

      let us say it is y;

              163 + y  = 180

                        y  = 180 - 163 = 17°

    For the second, assume it is z;

            69 + z = 180

                    z = 180 -69  = 111°

The sum of the internal angles of the triangle;

    y + z + 2x   =  180

     17 + 111 + 2x  = 180

                    2x  = 180 - 128

                     2x  = 52

                       x = [tex]\frac{52}{2}[/tex]   = 26

The value of x is 26

Answer:

4 [tex]\frac{1}{6}[/tex]

Step-by-step explanation:

When adding fractions, you want to make the denominators of the fraction the same. To do this, we can multiply both the numerator and denominator of 3/4 by 3. When changing either a denominator or numerator in a fraction, you must do the same thing to the numerator as the denominator.

Now we have [tex]\frac{3\cdot3}{4\cdot3} = \frac{9}{12}[/tex]. To add 9/12 and 5/12, we keep the denominator the same, and add the numerators, getting [tex]\frac{9+5}{12} =\frac{14}{12}[/tex]. This is greater than 1, so we can take 12/12 from 14/12, and make it [tex]1 \frac{2}{12}[/tex]. If we then add 3, we get [tex]4 \frac{2}{12}[/tex], which simplifies to [tex]4 \frac{1}{6}[/tex]

Answer:

Step-by-step explanation:

Note: Perimeter = sum of all the lengths of the shape.

In the case of a square, since all the sides are equal.

This means that if one side = 8x + 4, the perimeter would be 4 times 8x+4 since there are 4 equal sides in a square.

Perimeter = 4 ( 8x + 4)

Perimeter = 32x + 16

We also get told in the question that the perimeter = 80 inches.

Meaning that:

32x + 16 = 80

From here we can solve for x.

Subtract 16 from both sides:

32x = 80 - 16

32x = 64

Divide both sides by 32 to solve for x.

x = 64/32 = 2

Answer:

A senior citizen will pay $4.97

Step-by-step explanation:

Mathematically, discount = discount percentage * marked price

Sales price = marked price - discount

In the question, marked price = $6

First, we have a discount of 10%, so therefore , the sales price will be;

$6 - (10/100 * $6 ) = $6 - $0.6 = $5.4

Now, a further 8% discount was given to senior citizens,

The extra discount for senior citizens is thus;

8/100 * 5.4 = $0.432

Amount to be paid by senior citizens = $5.4 - $0.432 = $4.968. which is $4.97 to the nearest cent

Answer:

the answer is $4.97.

Step-by-step explanation:

157 = .166 x

157/0.166 = x

945.78313253 = x

157 is 16.6% of 945.78313253, which rounds to 946.

The 157 is approximately 16.6% of 945.78313253012 rounded to the nearest decimal place.

To find the number that 157 is 16.6% of,  set up the following equation:

16.6% = 0.166 (since percentages expressed as decimals)

0.166 × x = 157

To isolate x, we divide both sides of the equation by 0.166:

x = 157 / 0.166

Simplifying the division:

x ≈ 945.78313253012
