Answer:
The distance between two points on the globe 30° north and 50° south at the equator is the same as latitude, roughly 69 miles. At 45 degrees north or south, the distance between is about 49 miles (79 km). The distance between longitudes reaches zero at the poles as the lines of meridian converge at that point.
Step-by-step explanation:
Sorry If it is wrong.
We can simplify it by combining like terms
We get -7x -3x = -10x and -10x+8x = -2x
then we get -2x + 2 = -8
-2x = -10
x = 5
Mr. Rowley: 16:14 which reduces to 8:7
Ms. Rivera: 64:60 -> 16:15
The ratios are not equivalent because when they are reduced, they do not equal the same thing.
Answer:
Daniel would have to earn 35 or more points to put him and his teammate ahead.
Step-by-step explanation:
Daniel: 40 points
Zeke: 75 points
Opposing team: 150
Daniel + Zeke + x = Opposing team
40 + 75 + x = 150
- rearrange -
150 = 40 + 75 + x
150 = 115 + x
150 - 115 = x
35 = x
Answer:
x = 
Step-by-step explanation:
The absolute value always returns a positive value but the expression inside can be positive or negative, that is
x + 4 = 3x - 5 ( subtract 3x from both sides )
- 2x + 4 = - 5 (subtract 4 from both sides )
- 2x = - 9 ( divide both sides by - 2 )
x =
OR
-(x + 4) = 3x - 5
- x - 4 = 3x - 5 ( subtract 3x from both sides )
- 4x - 4 = - 5 ( add 4 to both sides )
- 4x = - 1 ( divide both sides by - 4 )
x = 
As a check
Substitute these values into the equation and if both sides are equal then they are the solutions
| + 4 | = | 
| =
right side = 
- 5 =
left side = right side , thus x = is a solution
check second solution
| + 4 | = | 
| =
right side = 
- 5 = -
right side ≠ left sides, hence not a solution
