What is the value of x and y?

Answers

Answer:

x = 5/4

y = 15/16

Step-by-step explanation:

y = 3/4x

5/2 x + 2y = 5

Substitute the first equation into the second equation

5/2x + 2(3/4x) = 5

5/2x + 3/2x = 5

Combine like terms

8/2x = 5

4x = 5

Divide by 4

4x/4 = 5/4

x = 5/4

Now find y

y = 3/4 x = 3/4 ( 5/4) = 15/16

X=5/4
Y=15/16
Those are the values

Angel and Jayden were at track practice. The track is 2/5kilometers around. Angel ran 1 lap in 2 minutes. Jayden ran 3 laps in 5 minutes. How many minutes does it take Angel to run one kilometer?
pls, help I don't want to fail!!

Answers

Answer:

5 minutes

Step-by-step explanation:

if one lap is 2/5 km then you  would need to run 2.5 laps to run a km and if it takes 2 minutes to run a lap then you multiply 2 minutes by the number of laps aka 2.5 so 2 times 2.5=5

5 minutes to run one kilometer

In the figure d, e, and f are parallel lines. What is the value of x?

Answers

Answer:

x = 150

Step-by-step explanation:

Corresponding angles

180 - 60 = x-30

120 = x-30

150 = x

X=150

Explanation:
You take 180 as a straight line is 180° and you make the equation 180-60=x-30 Then you subtract 180 and 60 which equals 120 then add 30 to both sides and the equation after that should look like 150=X and thats your answer.

180-60=x-30
120=x-30
+30. +30
150=X

Select the correct systems of equations.

The expression that is equivalent to 18⅕ - (-22⅖) - (-40⅕) is: D. 18⅕ + 22⅖ + 40⅕.

What are Equivalent Expressions?

When the values of two expressions are equal, the two expressions are said to be equivalent to each other.

Given the expression:

18⅕ - (-22⅖) - (-40⅕)

Open the bracket (note, negative times negative = positive)

18⅕ - (-22⅖) - (-40⅕) = 18⅕ + 22⅖ + 40⅕

Therefore, the expression that is equivalent to 18⅕ - (-22⅖) - (-40⅕) is: D. 18⅕ + 22⅖ + 40⅕.

you and 5 of you friends go out to dinner. the total bill is $89. the group also wants to leave a 15% tip. if the total bill and tip are split evenly, approximately, how much will each person pay?

Answers

About $17.05,
Since 89/100= 1% of the total bill= 0.89
0.89*15= the total tip= 13.35
Add the total bill and the tip together would be $102.35,
And then you divide that between the 5 of your friends and you, so
102.35/6 which would equal to $17.0583 (3 repeating) for each person.
Each person would pay $20.47. 15% tip= $13.35 + $89= $102.35/5= 20.47
