Answer:
Step-by-step explanation: v> -2 the > has a line under it
Answer:
Step-by-step explanation:
First let's convert the mixed numbers into improper fractions.
Let the number be n, so we can write an equation from the word problem as:
Now, we do algebra and solve for n:
hence the number is 25/21
Answer:
x = 130 degrees
Step-by-step explanation:
let's imagine we move the point x further and further to the right (and move the connected lines with it) until we get a flat line that connects the two parallel lines.
in this case we have x = 180 degrees, and the top and bottom angles are both 90 degrees.
so, we have a total of all angles of 180 + 90 + 90 = 360 degrees.
this total had to stay the same no matter how we move x outward or inward.
so, even in the situation in the picture the sum of all 3 angles must be 360 degrees.
therefore we get
360 = 120 + 110 + x
360 = 230 + x
x = 130 degrees
Equation 1) 5x + 3y = 16
Equation 2) 3x - 5y = -4
Multiply all of equation 1 by 3, and all of equation 2 by 5.
1) 3(5x+3y=16)
2) 5(3x-5y=-4)
Simplify.
1) 15x + 9y = 48
2) 15x - 25y = -20
Subtract equations from each other.
34y = 68
Divide both sides by 34.
y = 2
Plug in 2 for y in first equation.
5x + 3y = 16
5x + 3(2) = 16
Simplify.
5x + 6 = 16
Subtract 6 from both sides.
5x = 10
Divide both sides by 5.
x = 2
(2, 2)
