Answer:

a = -6

7 -6a = -5 -8a

- 6a = - 5 - 8a - 7

- 6a + 8a = - 5 - 7

2a = - 12

2a/2 = - 12/2

a = -6

What value of x makes 1/2 (3x+4) =1/2

Sever21 [200]

Answer:

x = -1

Step-by-step explanation:

1/2 (3x +4 ) = 1/2

1/2 x 3x + 1/2 x 4 = 1/2

1.5 x + 2 = 1/2

1.5x = 1/2 -2

1.5x = -1.5

1.5x /1.5 = -1.5/1.5

x = -1

What is the value of x? Enter your answer in the box. °

pashok25 [27]

Answer:

x = 127 degrees

Step-by-step explanation:

The sum of the interior angles is (n-2)180, so in this case it would be

(6-2)180

(4)180

720

Then you can substitute the given angle measurements to get the equation:

112+133+128+100+120+x = 720

593+x = 720

x = 127

Help me please ;-;!!!!! Use a coordinate grid to create a map of a town with at least five different locations, such as a house,

Sholpan [36]

A. Our diagram have six location: my house (2,1), a movie theater (5,3), the school (6,6), the police station (3,-2), the airport (-3,3), and the mall (-2,-3)

B. Distance between my house and the movie theater:
To calculate the distance we are going to use the points (2,1) and (5,3) to create a right triangle with tow legs of measures 3 and 2; the hypotenuse of the right triangle will be the distance between my house and the movie theater.
Using the Pythagorean theorem:
$d^2=3^2+2^2$
$d^2=9+4$
$d^2=13$
$d= \sqrt{13}$
We can conclude that the distance between my house and the movie theater is $\sqrt{13}$

Our second distance is the distance between the police station and the airport:
This time we are using the points (3,-2) and (-3,3) to create a right triangle with legs of measures 6 and 5; the hypotenuse of our triangle will be the the distance between our points:
$d^2=6^2+5^2$
$d^2=36+25$
$d^2=61$
$d= \sqrt{61}$
We can conclude that the distance between the police station and the airport is $\sqrt{61}$

C. Distance form the park to the Fire Station:
$d^2=3^2+1^2$
$d^2=9+1$
$d^2=10$
$d= \sqrt{10}$
We can conclude that the distance from the park to the Fire Station is $\sqrt{10}$

Distance from the stadium to the mall:
$d^2=2^2+1^2$
$d^2=4+1$
$d^2=5$
$d= \sqrt{5}$
We can conclude that the distance from the stadium to the mall is $\sqrt{5}$

D. What is the distance between your house and the mall?
Answer:
$d^2=4^2+4^2$
$d^2=16+16$
$d^2=32$
$d= \sqrt{32}$
$d=4 \sqrt{2}$
We can conclude that the distance between my house and the mall is $4 \sqrt{2}$

What is the distance between the movie theater and the school?
answer:
$d^2=3^2+1^2$
$d^2=9+1$
$d^2=10$
$d= \sqrt{10}$
We can conclude that the distance between the movie theater and the school is $\sqrt{10}$
