Answer:

Explanation:
I took the test and passed.
Answer:
(x,y) = (5.8,-0.4)
Step-by-step explanation:
1.) x + 2y = 4.2 - 2y = 5
2.) { x + 2y =5
{ 4.2 - 2y = 5
3.) { x + 2y = 5
{ y = -0.4
4.) x + 2x ( -4.0 ) = 5
5.) x= 5.8 ( a possible solution )
6.) ( x , y ) = ( 5.8 , -0.4 ) check to the solution
7.) 5.8 + 2 x ( -0.4 ) = 4.2 - 2 x ( -0.4 ) = 5
8.) 5 =5 =5
Mia walked 7km/h so after 1 hour, she is 7 km north of the house of Julia
Samantha walked 11km/h so after 1 hour, she is 11 km west of the house of Julia.
The points where Mia and Samantha are after 1 hour , and the house of Julia form a right triangle with sides 7 and 11 km. The distance between the girls, is the hypotenuse of his triangle.
by the pythagorean theorem:
Answer: 13 km
P(volleyball and baseball) = 4/200 x 100 = 2%
P(either volleyball or baseball) = P(volleyball ∪ baseball) = P(volleyball) + P(baseball) - P(volleyball and baseball) = 12% + 15% - 2% = 25%.
25% play either volleyball or baseball.
The answer would be B) 5.90x > 236
This is because Jay needs at least 236 therefore the money he earns from working at the ice cream parlor would need to be higher than 236.
