Step-by-step explanation:
I think you are trying to find x, I dunno, but if you are here's the solution.
when trying to find x, your main goal is to shift all x terms to one side.
For the first one
4x-3 = 5x-3
Carry all x terms to one side:
(4x-3)-5x = (5x-3)-5x
4x-5x-3 = -3
Shift all constants (purely just numbers, no x) to the other side
(4x-5x-3)+3 = (-3)+3
4x-5x = 0
-x = 0
x = 0
The second one:
-2x = 3x-5
5x = -5
x = -1
Done, have fun with math!
Fewer because October clearly is higher then where December will be when the time comes.
Let X be the first number
there is a 2 numbers distance between each even number eg.2 ,4, 6, 8, etc.
So the 2nd number is X+2
The sum of the 1st and 2nd numbers = 14
X + X+2 =14
2X +2 =14
2X = 14-2
2X = 12
X = 12/2
X = 6
Therefore,
The first number i.e, X = 6
And the second number i.e, X+2 = 6+2 =8
******************************************************************************
This is the only positive pair in case of two consecutive numbers if the are even numbers but not consecutive there will be more pairs
12 + 2 = 14
10 + 4 = 14
8 + 6 = 14 (Already found)
Answer:
43°
Step-by-step explanation:
(x + 53)° + (x + 74)° + 73° = 180°
(x + 53 + x + 74)° = 180° - 73°
(2x + 127)° = 107°
2x + 127 = 107
2x = 107 - 127
2x = - 20
x = - 20/2
x = - 10
Answer:
Step-by-step explanation:
Given: f(x) = 4(3x - 5)
Is required to find f⁻¹(x)
f(x) = y = 4(3x - 5)
∴ y = 4 * 3x - 4 * 5
∴ y = 12x - 20 ⇒ add 20 to both sides
∴ y + 20 = 12x ⇒ divide both sides by 12
∴ 
Replace the places of x and y.
∴ 
∴
