Answer:

1520

Step-by-step explanation:

Pela pergunta acima, sabemos que:

1 parcela mensal = 304

5 parcelas mensais = x

Multiplicação cruzada

x = 5 prestações mensais × 304/1 prestações mensais

= 1520

Portanto, o valor que ele pagou pelo dispositivo é 1520

Answer: 192 cm^2

Step-by-step explanation:

With parallelograms like this, you an just multiply the width and length to find the area. If you cut the shape up in a certain way, it would make a rectangle, so the formula length*width=area would also apply to parallelograms.

Then go back to the R and move to the horizontal y line and that value is your y value(-4)

ALWAYS remember X comes BEFORE Y

therefore (2,-4)

What are the solutions 2x^2 +7x=4

elena55 [62]

So your equation is $2x^{2} +7x = 4$ . You need to simplify this answer.
So first off, do 2x times 2x.
2 x 2 = 4.
Your equation is now $4x + 7x = 4.$
You're already off to a great start, so now let's add 4x + 7x. It is 11x.
Your equation is almost done! It's $11x = 4$ right now.
Divide both sides by 11, and your answer is...
0.36363636 and so on, or you can round to the nearest hundreth, in which it will be

0.36.

I hope I helped!

Is (3,-4) a solution of x=-4

jekas [21]

Answer:

Step-by-step explanation:

3 is the x coordinate/ integer and -4 is the y coordinate and the integer so it wouldn't make sense

x= 3 is a solution

and id you don't understand the first thing i said watch this

#1. 3, - 4

#2. x= - 4

#3. substitute/replace the x with what the x coordinate is

#4. it will be 3= - 4

#5. as you can see the numbers don't equal each other so it's a no solution
