Answer:

60%

Step-by-step explanation:

15/25=60%

you ate 15 out of 25 so that means you ate 3 out of 5 if you divide both 15 and 25 by 5. And 3 out of 5 is 60%.

Solve the system by substitution. x= x= \,\,-y-5 −y−5 -3x+7y= −3x+7y= \,\,-45 −45

Answer:

(1, -6)

Step-by-step explanation:

the layout of your question is kind of confusing, but i'm guessing this is the system of equations

x = -y - 5

-3x + 7y = -45

plug in x to the second equation

-3(-y - 5) + 7y = -45

distribute

3y + 15 + 7y = -45

combine like terms

10y = - 60

divide by 10

y = -6

plug y into first equation

x = -(-6) - 5

x = 6 - 5

x = 1

Solve for x in this equation: 3/4+ |5-x| = 13/4

Rom4ik [11]

Answer:

x = 2.5 or 7.5

Step-by-step explanation:

Subtract 3/4.

|5 -x| = 10/4 = 2.5

This resolves to two equations:

5 -x = 2.5 ⇒ x = 5 -2.5 = 2.5
5 -x = -2.5 ⇒ x = 5 +2.5 = 7.5

The solutions are x = 2.5 or 7.5.
