<h2>Greetings!</h2>

Answer:

€16.40

Step-by-step explanation:

First, we need to divide £12.30 by 3 to find out how many groups of 3 there is:

12.3 ÷ 3 = 4.1

Now we can multiply this by 4 to find the euro equivalent:

4.1 * 4 = 16.4

So £12.30 is €16.40

5x^(-2)-17x^(-1)+6<br> i’m so confused pls help<br> will give brainliest
laila [671]

It's a quadratic equation in disguise. If you let y=x^{-1}, then y^2=x^{-2}, and we can rewrite the equation as

5y^2-17y+6=0

Solve for y however you like; we get y=\dfrac25 and y=3.

But we want to solve for x, so we have

y=x^{-1}=\dfrac25\implies x=\dfrac52

y=x^{-1}=3\implies x=\dfrac13

Five more than the product of a number and 4 is equal to 8
Maru [420]

Answer:

4x+5=8

x=\frac{3}{4}

Step-by-step explanation:

Let

x ---> the number

we know that

The algebraic expression is equal to multiply the number by 4, add 5 and equal 8

so

4x+5=8

Solve for x

subtract 5 both sides

4x=8-5\\4x=3

Divide by 4 both sides

x=\frac{3}{4}
