Yes it can, and it can be written as 3:5, 3 to 5, 3/5
Answer:
Real part = -5
Step-by-step explanation:
The real part of a complex number of the form a+bi, is that which doesn't have the "i" (imaginary unit) factor. therefore the real part is "a"
In this case (-5+3i) the real part is -5.
Let x as number of adult tickets and y as number of student tickets
x+y=1260
y=1260-x
5x+1y=2688
5x+1(1260-x)=2688
5x+1260-x=2688
4x=2688-1260
x=1428÷4
x=357 adult tickets sold
y=1260-357
y=903 student tickets sold
<span>Simplifying
-7 + x + 4 + 4x = x + -3 + 6 + 3x
Reorder the terms:
-7 + 4 + x + 4x = x + -3 + 6 + 3x
Combine like terms: -7 + 4 = -3
-3 + x + 4x = x + -3 + 6 + 3x
Combine like terms: x + 4x = 5x
-3 + 5x = x + -3 + 6 + 3x
Reorder the terms:
-3 + 5x = -3 + 6 + x + 3x
Combine like terms: -3 + 6 = 3
-3 + 5x = 3 + x + 3x
Combine like terms: x + 3x = 4x
-3 + 5x = 3 + 4x
Solving
-3 + 5x = 3 + 4x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4x' to each side of the equation.
-3 + 5x + -4x = 3 + 4x + -4x
Combine like terms: 5x + -4x = 1x
-3 + 1x = 3 + 4x + -4x
Combine like terms: 4x + -4x = 0
-3 + 1x = 3 + 0
-3 + 1x = 3
Add '3' to each side of the equation.
-3 + 3 + 1x = 3 + 3
Combine like terms: -3 + 3 = 0
0 + 1x = 3 + 3
1x = 3 + 3
Combine like terms: 3 + 3 = 6
1x = 6
Divide each side by '1'.
x = 6
Simplifying
x = 6</span>
Answer:
2
Step-by-step explanation:
when you add 6+(-9)= -3 and -(-5)=5 because negative and negative is positive.so -3+5=2.
