Answer:
a. t = I/Pr
b. The value of t in the table is 3 years
Step-by-step explanation:
Solve for t in the formula.
I = Pr
~Divide pr to both sides
I/Pr = t
Using the formula above, we can solve for t.
75/(500)(0.05) = t
75/25 = t
3 = t

Which set of number shows a proportional relationship?
Answer:
D
Step-by-step explanation:
Explain how to solve the equation and how to check the solution.
40 = 8y
there the answers-
Use the inverse operation to isolate the variable. Undo multiplication by dividing by 8 on both sides of the equation. Simplify by completing the divisions, 40 ÷ 8 = 5, and 8 ÷ 8 = 1. The solution is y = 5. Check the solution by substituting 5 for y in the original equation, and then simplify. 8 × 5 = 40 and 40 = 40 is a true statement, so 5 is the solution.
equations by using inverse operations, including squares, square roots, cubes, ... A pair of inverse operations is defined as two operations that will be ... The following examples summarize how to undo these operations using their ... x is divided by 2, so we multiply by 2 on both sides. 2. 8 2. 2 x. ∙ = ∙. Solution: 16. explanation:

Can someone explain to me how I can eliminate one of the variables to solve this equation for one of the variables?
Answer:
In the elimination method you either add or subtract the equations to get an equation in one variable. When the coefficients of one variable are opposites you add the equations to eliminate a variable and when the coefficients of one variable are equal you subtract the equations to eliminate a variable.

Answer:
x = 1 and y = 4
Step-by-step explanation:
Multiply the top equation by 7 on both sides, and then cancel it out:
7(5x + y) = 7(9)
35x + 7y = 63
Now use this equation to cancel out -7y on the second equation:
35x + 7y = 63
10x - 7y = -18
45x = 45
x = 1
Now that we have our x-value, we can plug it into one of our two original equations:
5(1) + y = 9
y = 4
