If we have the expression 2b = -3, then the value of the expression 1 - 4b is 4.
Step 1: Solving for 'b'
We are given the equation 2b = -3. To isolate 'b,' we need to get rid of the coefficient 2 attached to 'b'. To do that, we'll divide both sides of the equation by 2:
2b / 2 = -3 / 2
b = -3/2
Step 2: Substitute 'b' in the expression 1 - 4b
Now that we have the value of 'b' as -3/2, we can substitute it into the expression 1 - 4b:
1 - 4(-3/2)
Step 3: Simplify the expression
To simplify the expression, we'll perform the multiplication first:
1 + 6/2
Next, we add 1 and 6/2:
1 + 3 = 4

Answer:
Step-by-step explanation:
2b= -3, what is the value of 1 – 4b?
2b= -3
b = -3/2
Then 1 - 4b
= 1- 4(-3/2)
= 1+12/2
= 1+ 6
= 7
Answer:
x = 3
Step-by-step explanation:
Solve for x over the integers:
5^(2 x - 3) = 125
Multiply both sides by 125:
5^(2 x) = 15625
15625 = 5^6:
5^(2 x) = 5^6
Equate exponents of 5 on both sides:
2 x = 6
All equations give x = 3 as the solution:
Answer: x = 3
Answer:
x=14 or 14x
Step-by-step explanation:
5*2=10
5*3=15
10x-15=125
+15=+15
10x=140
/10=/10
x=14
