Step-by-step explanation:
From the question we are told that:
Thought of Number x
Multiplied it by 8
Subtracted 4
Divided the result by 2
Generally the equation for x is mathematically given by
The measurement of angle C is 228°
Answer:
x = -1/3
Step-by-step explanation:
We have,
sin(x + 7) = cos(4x + 8)
We need to find the value of x.
We know that,
sin(90-x) = cosx
So,
sin(90-(x + 7)) = cos(4x + 8)
cos(x+7) = cos(4x + 8)
i.e.
(X+7) = (4x+8)
7-8 = 4x-x
-1 = 3x
x = -1/3
Answer:
27
Step-by-step explanation:
If a= -3 what is 3a^2 = 27
In this question, you're solving for x.
Solve for x:
x + 4.2 = 7
You need to get x by itself, to do so, you would need to subtract 4.2 from both sides:
x = 2.8
Answer:
x = 2.8
