ANSWERS- 15.) the second part would be 46.25 i don’t know the first part so sorry though

16.) x=33.3 and 3x+10=57.3

Idk if any of these are right though I haven’t done this in a long time sorry if I made mistakes.
STEPS-
You would find out the measure of the type of line which would be 180 since it’s straight. Then you would solve it algebraically so you would do 4x-5=180, add 5 to both sides (5 would cancel out & 180 would be 185) the divide 185 by 4x and you would get x = 46.25. Sorry I don’t know the other equation for 15.

For 16.) you would turn the equation into 3x-10=90 since it’s a 90 degree angle. Add 10 to both sides so that they cancel each other out then add 10 to 90 and then you should get 100. Now your equation should look like this 3x=100. Next do 100➗3x= 33.3. Now your answer is x=33.3 and the second part would be 90-33.3= 57.3.

Two swimmers start out from opposite ends of a swimming pool(red side and blue side). They cross each other for the first time a

daser333 [38]

Answer:

13 yds

Step-by-step explanation:

the blue side starter (B) swims 29yd in the time it takes the red side starter (R) to swim 21yd

their combined distance, when they meet, is 50yd (length of pool)

they pass each other and continue to the ends of the pool (combined distance, 100yd)

they swim towards each other again, and pass a second time (combined distance, 150yd)

at this point, R has swum 63yd (3*21) -- one length plus 13yd

so RS is 13yd from the blue end
