Answer:
x = - 3 3/8
Its negative 3 3/8
Step-by-step explanation:
13x + 7 = 5x - 20
Subtract 5x from both sides
8x + 7 = -20
Subtract 7 from both sides
8x = -27
Divide both sides by 8
x = -27/8
x = - 3 3/8
The area of the continent of Susan America which is 6,888,000 square miles can be written as 688*
.
Given that the area of the continent of Susan America be 6888000 square miles.
We are required to express the area in the multiplication form by using the place values.
Area is basically quantity that expresses the extent of a region on the plane or on a curved surface.
Multiplication is basically finding the number which is product of two numbers.
6888000 can be written as 6888* which can be found out by the cube of 10 and multiply that by 6888.
Hence the area of the continent of Susan America which is 6,888,000 square miles can be written as 6888*.

Answer:
Yes
Step-by-step explanation:
Let's begin by putting together some equations:
Seth has charges $39 and then $13 per hour. Since "hour" is our variable, let's write that as $13h where h = the number of hours.
Seth = 39 + 13h, $39 plus $13 times the number of hours
Malcolm charges $55 and then $11 per hour. So:
Malcolm = 55 + 11h, $55 plus $11 times the number of hours
Our goal is to find out how many hours both have to work before they charge the same amount. So let's set our Seth and Malcolm equations equal to one another.
39 + 13h = 55 + 11h, because we want to solve for h to see the number of hours.
First let's subtract 39 from each side:
(39 + 13h) - 39 = (55 + 11h) - 39
13h = 16 + 11h
Now let's subtract 11h from each side:
(13h) - 11h = (16 + 11h) - 11h
2h = 16
Simplify and solve for h by dividing each side by two:
(2h)/2 = (16)/2
h = 8
So Malcolm and Seth would have to work for 8 hours before both earn the same amount. After 8 hours, Seth would earn more than Malcolm. Before 8 hours, Malcolm would earn more than Seth.
Answer:
(-4, 3)
Step-by-step explanation:
This is an increase of 8 in the y coordinate, so the answer is (-4, -5 + 8) or (-4, 3).
