Last week Tina are in $2.50 less than twice what earned how much did Tina earn last week if add earn $6.50?

Tina earned $11.5

Step-by-step explanation:

From the question, we are told that Tiana earns 2.50 less than twice what is earned by Add

let us have x as what is earned by Add

Thus, we have what is earned as 2x-2.5

Now Add, earned 6.50, so we want to know what Tina earned

That would be;

2(6.5) - 2.5

= 13-2.5

= 10.5

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.
