Answer and Step-by-step explanation:

Haven't done this in a while, so here we go:

The rule (I'm not really sure) would have to be negative number and negative number.

This means that:

(4, 0) would become (-4, 0) A'

(6, -2) becomes (-6, 2) B'

(8, -7) becomes (-8, 7) C'

and (0, -5) becomes (0, 5) D'

If the exchange rate is €1.20 to £1, how many pounds sterling would you get for €180?

Len [333]

Answer:

150 pounds

Step-by-step explanation:

1.20 euros = 1 pound

180 euros = x pounds

Set up the proportion

1.20 Euros/1 pound = 180 Euros / x pound Cross multiply

1.20*x = 1 * 180 Combine

1.20 x = 180 Divide by 1.2

x = 180 / 1.20

x = 150 pounds.

As a bonus, you might want to try and guess which is the stronger currency.

Y-1=4y-2/3<br> y=_____<br> solve

Vikki [24]

Y - 1 = 4y - 2/3. Move the ys over to one side, +4y crosses over to become -4y,
and -1 crosses over the right side to become +1.
y -4y = -2/3 + 1
-3y = 1 - 2/3
-3y = 1/3 Divide both sides by -3.

-3y/-3 = (1/3) / -3.
y = 1/3 * -1/3
y = - 1/9

Fill the value of the expression 24 3/5 +4 ×(8 1/5-2)

Julli [10]

First off, we'll convert the mixed fractions to "improper",

$\bf \stackrel{mixed}{24\frac{3}{5}}\implies \cfrac{24\cdot 5+3}{5}\implies \stackrel{improper}{\cfrac{123}{5}}
\\\\\\
\stackrel{mixed}{8\frac{1}{5}}\implies \cfrac{8\cdot 5+1}{5}\implies \stackrel{improper}{\cfrac{41}{5}}$

$\bf 24\frac{3}{5}\times \left( 8\frac{1}{5}-2 \right)\implies \cfrac{123}{5}\left( \cfrac{41}{5}-2 \right)\impliedby \mathbb{PEMDAS}
\\\\\\
\cfrac{123}{5}\left( \cfrac{41-10}{5} \right)\implies \cfrac{123}{5}\left( \cfrac{31}{5} \right)
\\\\\\
\cfrac{123\cdot 31}{5\cdot 5}\implies \cfrac{3813}{25}\implies 152\frac{13}{25}$
