The equivalent expression is 15x + 104 /4
<h3>What are algebraic expressions?</h3>
Algebraic expressions are defined as expressions comprised of constants, variables, terms, coefficients and factors.
They are also made up of arithmetic or mathematical operations such as;
- Addition
- Subtraction
- Division
- Multiplication
- Bracket, etc
Given the expression:
2(3/4x+7) - 3(1/2x-5)
solve for the bracket
3 ( 3x + 28/4) - 3 (x - 10 /2)
expand the bracket by multiplying
9x + 84 / 4 + 3x + 10/ 2
Find the lowest common multiple
9x + 84 + 6x + 20 /4
collect like terms
15x + 104 /4
Thus, the equivalent expression is 15x + 104 /4

Answer:
P(B)=0.7
Step-by-step explanation:
When the events do not affect each other, they are known as independent events. In other words, two events are independent if the outcome of the second event is not affected by the outcome of the first event.
If A and B are independent events, the probability that both events will occur is the product of the probabilities that the individual events will occur:
P(A and B)= P(A)*P(B)
In this case, P(A and B)= 0.21 and P(A)= 0.30
Replacing:
0.21=0.30*P(B)
Solving:

<u><em>0.7=P(B)</em></u>
