Jada has$20 to spend on games and rides at a carnival. Games cost $1 each and rides are $2 each. 1. Which equation represents the relationship between the number of games, , and the number of rides, , that Jada could do if she spends all her money?

A: x + y = 20

B: 2x + y = 20

C: x + 2y = 20

2. Explain what each of the other two equations could mean in this situation. Think about what is the invisible number in front of a variable that does not have a coefficient (number in front).

thus, the first answer choice, y = sec x, is the correct one

d .tv

step-by-step explanation:

the side tv is included in both triangles.   this means it corresponds to itself in the transformation.

this is justified by using the reflexive property, which states that anything is congruent to itself.

we can set up an equation to find the girls' ages. the equation is         28=0.5x-5+x. (comment if you need me to explain how i got this equation.) so, you add x and 0.5x to get 1.5x and add 5 to each side. your new equation is 33=1.5x. now divide both sides of the equation by 1.5 to get 22=x. because x is mary's age, to find jasmine's age we subtract mary's age from 28. we find that mary is 22 years old and jasmine is 6 years old.
