a=7.75

Step-by-step explanation:

19 = 4a − 12. 19+12=31. 31/4=7.75

Answer:

7.75

Step-by-step explanation:

19 = 4a - 12

add 12 to both sides

31 = 4a

divide by 4 to isolate the variable

7.75 = a

The system of Equations:

4x + 3y = 42

x + 7y = 44

Step-by-step explanation:

Let the price in dollars of

each pair of pants = x

each shirt = y

A customer at a store paid $42 for 4 pairs of pants and 3 shirts.

Hence:

4 × x + 3 × y = $42

4x + 3y = 42

At the same store, a second customer paid $2 more for 1 pair of pants and 7 shirts.

This means he, paid $42 +$2 = $44

Hence:

1 × x + 7 × y = 44

x + 7y = 44

The system of equations can be used to find the price in dollars of each pair of pants, x, and each shirt, y is

4x + 3y = 42.... Equation 1

x + 7y = 44..... Equation 2

The value of t is 7 and the coordinate is (5, 7). Therefore, option D is the correct answer.

Given that, in an xy-coordinate system, line l has a slope of -3. If the points (2, 16) and (5, t) are on line l.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The formula to find the slope of a line is slope = (y2-y1)/(x2-x1)

Now, substitute m=-3, (x1, y1)=(2, 16) and (x2, y2)=(5, t) in slope formula, we get

-3 =(t-16)/(5-2)

⇒ -3 =(t-16)/3

⇒ t-16=-9

⇒ t=7

The value of t is 7 and the coordinate is (5, 7). Therefore, option D is the correct answer.

Answer:

w=6 in

l=3 in

Step-by-step explanation:

let w = width and length be 'w-3'

Two sides of w and two sides of (w-3) equal 18 sq in

18=2(w)+2(w-3)

18=2w+2w-6

4w=24

w=6

The width of rectangle is, 6 in.

And, Length of rectangle is 3 in.

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

The length of a rectangle is 3 inches less than its width

And, the area of the rectangle is 18 in.²

Now, We know that;

Area of rectangle = Length × Width

Let the width of rectangle = x

Hence, Length of rectangle = x - 3

Thus, We get;

Area of rectangle = Length × Width

18 = x (x - 3)

18 = x² - 3x

x² - 3x - 18 = 0

x² - (6 - 3)x - 18 = 0

x² - 6x + 3x -18 = 0

x(x - 6) + 3 (x - 6) = 0

(x - 6) (x + 3) = 0

x = 6 , x = - 3

But dimensions are not negative.

Hence, We get;

x = 6

Thus, the width of rectangle = 6 in.

Hence, Length of rectangle = x - 3

                                           = 6 - 3 = 3 in.

Answer:

10 i believe

Step-by-step explanation:

Answer:

The solution set is (2,4).

Step-by-step explanation:

Given that:

−2x + 2y =4         Eqn 1

−4x + 8y =24      Eqn 2

Multiplying Eqn 1 by -2

-2(-2x+2y=4)

4x-4y= -8     Eqn 3

Adding Eqn 2 and 3

(-4x+8y)+(4x-4y)=24-8

-4x+8y+4x-4y=16

4y=16

Dividing both sides by 4

[tex]\frac{4y}{4}=\frac{16}{4}\\y=4[/tex]

Putting y=4 in Eqn 1

-2x+2(4)=4

-2x+8=4

-2x=4-8

-2x=-4

Dividing both sides by -2

[tex]\frac{-2x}{-2}=\frac{-4}{-2}\\x=2[/tex]

Hence,

The solution set is (2,4).

Parallel lines are those lines that are always the same distance apart and parallel lines do not intersect or meet each other.

The street that is parallel to 1st Ave is 2nd Ave.

Parallel lines are those lines that are always the same distance apart and parallel lines do not intersect or meet each other.

Example:

Line A and Line B have an angle of zero between each other.

This means Line A and Line B are parallel to each other.

We have,

Five streets:

1st ave

2nd ave

Central ave

D steet

Main road

Now,

Central Ave and the main road are parallel to each other.

1st Ave and 2nd Ave are parallel to each other.

D Street is perpendicular to 1st Ave and 2nd Ave.

Central Ave and Main Road are also perpendicular to 1st Ave and 2nd Ave.

We see that,

The street that is parallel to 1st Ave is 2nd Ave.

Thus,

The street that is parallel to 1st Ave is 2nd Ave.
