Answer:
the answer to the other number is 407
Step-by-step explanation:
6x-2=5x-7-3x
-3x
6x-2=2x-7
+2 +2
6x= 2x-5
-2x -2x
4x = -5
/4 /4
X=-5/4
You can do part a using The Pythagoras theorem:-
30^2 = x^2 + 24^2
x^2 = 30^2 - 14^2 = (30+24)(30-24) = 324
x = 18
Answer:
√x+3=13
Step-by-step explanation:
The equation is √x+3=13 is radical because the unknown, x appears under a radical sign √.
To solve the equation, the unknown is left on one side of the equal sign and then both sides of the equal sign are raised to an equal power which would remove the radical sign.
For example,
√x+3=13
√x=13-3
√x=10
Removing radical.
(√x)²=10²
x=100
