Will give brainliest!! An unknown number y is 10 more than an unknown number x. The number y is also x less than 3. The equations to find x and y are shown below.

y = x + 10
y = −x + 3

Which of the following statements is a correct step to find x and y?

Here are your answer choices:

A) Add the equations to eliminate x.

B) Multiply the equations to eliminate y.

C) Write the points where the graphs of the equations intersect the x-axis.

D) Write the points where the graphs of the equations intersect the y-axis.

Fiona races bmx around a circular dirt course. if the radius of the course is 70 meters, what is the total distance fiona covers in two laps of the race? a. about 30,772 meters b. about 15,386 meters c. about 879.2 meters d. about 439.6 meters e. about 219.8 meters23 points hurry

Asays "we are both knaves" and b says nothing. exercises 24–31 relate to inhabitants of an island on which there are three kinds of people: knights who always tell the truth, knaves who always lie, and spies (called normals by smullyan [sm78]) who can either lie or tell the truth. you encounter three people, a, b, and c. you know one of these people is a knight, one is a knave, and one is a spy. each of the three people knows the type of person each of other two is. for each of these situations, if possible, determine whether there is a unique solution and determine who the knave, knight, and spy are. when there is no unique solution, list all possible solutions or state that there are no solutions. 24. a says "c is the knave," b says, "a is the knight," and c says "i am the spy."
