Mira has breakfast at a restaurant. She leaves a 20% tip of $1.80

1 answer:

7 0

Let x be the price of the breakfast.

We know that 20 percent of x is 1.80

Let's write this as a mathematical equation

0.2 x = 1.8

Let's divide both sides by 0.2 to isolate the x

x = 1.8 / 0.2

= 9

The price of the breakfast was $9.

Have an awesome day! :)

Halla el conjunto solución del siguiente sistema de ecuaciones aplicando el método de reducción: 2x + 3y = 8 x – 5y = 6

AysviL [449]

Answer:

x = 7.535 and y = 0.307

Step-by-step explanation:

Given that,

Two equations,

2x + 3y = 8 ...(1)

x – 5y = 6....(2)

Multiply equation (2) by -2.

-2x + 10y = -12....(3)

Now, adding equations (1) and (2),

2x + 3y -2x + 10y = 8-12

13y = 4

y = 0.307

Put the value of y in equation (2).

x – 5(0.307) = 6

x = 6 + 1.535

x = 7.535

So, the solutions of the given equation are x = 7.535 and y = 0.307.

I live in NM and im a senior in high school. The PARCC test is required for me, do I have to pass that test in order to graduate

nadezda [96]

These tests are designed to better replacements for old versions of state tests because (as PARCC claims) they provide better information about students' skills and development to teachers and parents. In a nutshell, these examinations are meant to evaluate college and career readiness starting at a young age.
