Answer:
2
Step-by-step explanation:
Order of operations is not as applicable in this situation because we're just dealing with addition and subtraction. This is a simple case of plugging in values for the given expression.
x = 3
z = 4
So it becomes...
3 + 3 - 4
6 - 4
2
So with the given expression of x + x - z and the given values of x = 3 and z = 4, the expression should sum to: 2
Step-by-step explanation:
angle 2 = 180-39= 141°
angle 2 = 141°
F(x) = input the x
3x+2
multiply it by 3 and add 2
3*x+2=
3*5+2=
15+2 =
17
or if you meant 2x:
it would be the same just do:
3+2x
3+2*5
3+10
13
Answer:
n=-3
Step-by-step explanation:
3 * (n+1) = 2n
distribute
3n +3 = 2n
subtract 3n from each side
3n-3n+3 = 2n -3n
3 = -n
multiply by -1
-3 = n
Answer:
Step-by-step explanation:
Let "x" be the number.
Product of 6 and x (6*x), increased by 4 =
Product of 12 and x, (12*x), decreased by 20 = .
Set both expressions equal to each other and solve for x as shown below:
(equation)
Subtract 12 from both sides
Subtract 4 from both sides
Divide both sides by -6
