The answer is communative. hope that helped
Enable M = Mary's age now So Mike's age is 3M 3M + 4 = 2 (M + 4) = 2M + 8 Now, subtract 2M from the two factors. then you definitely have: M + 4 = 8 or M = 4 examine: Mike is now 12. In 4 years, Mary would be 8 and Mike would be sixteen.
==> I can't be sure of the equation. There's a blank space
between '5t' and '8', where an operation must be.
I think the operation is more likely ' + ' (addition). Brainly usually
does show the ' - ' if it's subtraction, but goes blank if it's addition.
Tell you what I'll do: Since you sound so desperate, and you're being
so generous with your points, I'll show you how to figure it out both ways.
----------------------------------------
If it's subtraction: 5t - 8 = 43
Add 8 to each side: 5t = 51
Divide each side by 5 : t = 51/5
t = 10 and 1/5
--------------------------------------------
If it's addition: 5t + 8 = 43
Subtract 8 from each side: 5t = 35
Divide each side by 5 : t = 7
Answer:
let x as a cointerior angle and find the
Using a system of equations, the meaning of point R is given as follows:
A number of books and their cost where both subscriptions cost the same.
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable. In a graph, the solution to the system is the intersection point of the two equations.
In this problem, the point R is the point in which:
3y = 96.
That is, the point in which the prices are equal, hence:
A number of books and their cost where both subscriptions cost the same.
