Answer:

X = 20 degrees

Step-by-step explanation:

1.) Form Equation. Since M is parallel to N and both lines are being cut by transversal T, we can say that the alternate exterior angles are congruent, so we know that 7x - 3 = 6x + 17.

2.) Isolate x. Move all the x to one side and all of the numbers to another side by subtracting by 6x on both sides and adding by 3 on both sides. You will get that x = 20 degrees.

Sabrina can spend at most $5, including tax, to buy 3 cards. She finds 2 cards priced at $1.25 each and 1 card priced at $1.99, not including tax. Which inequality could be used to determine the amount of money, in dollars, Sabrina can afford to spend on tax (x) when she buys the 3 cards?

2(1.25+1.99)−x≥5

2(1.25+1.99)−x≤5

2(1.25)+1.99+x≤5

2(1.25)+1.99+x≥5

Answers

Answer:

2(1.25)+1.99+x≤5

Step-by-step explanation:

Because it says "at most $5" that means it would be either 2(1.25+1.99)−x≤5

or 2(1.25)+1.99+x≤5, which narrows it down to two. The reason it is the second option is because she is only buying two cards that cost $1.25, hence this part of the equation: 2(1.25) +1.99+x≤5.
