in a last minute deal a holiday is reduced from £540 to £459. Calculate the percentage reduction in the price

harkovskaia [24]

Answer:

15%

0.15 x 100%

15%

The percentage reduction in price is 15%

Which expression is equivalent to 1/2 x + (-7) -2 q/4 x - (-2) ?

Marrrta [24]

Answer:

−1 /2 qx+ 1 /2 x-5

Step-by-step explanation:

Let's simplify step-by-step.

1 /2 x−7− 2q/ 4 x−(−2)

= 1 /2 x+−7+ (−1/2) qx+2

Combine Like Terms:

= 1 /2 x+−7+ (−1 /2 qx+2

=( −1 /2 qx)+( 1 /2 x)+(−7+2)

= −1 /2 qx+ 1 2x+−5

Answer:

= −1 /2 qx+ 1 /2 x-5

PtichkaEL [24]

(a) $x^{-5}$

(b) $3x^{-7}$

Solution:

To write each of the given expression in the form $ax^n$ :

(a) $\frac{x^3}{x^8}$

Using exponential rule: $\frac{a^x}{a^y}=a^{x-y}$

$$\frac{x^3}{x^8}=x^{3-8}$

$$\frac{x^3}{x^8}=x^{-5}$

(b) $\frac{6x}{2x^8}$

Divide numerator and denominator by the common factor 2, we get

$$\frac{6x}{2x^8}=\frac{3x}{x^8}$

Using exponential rule: $\frac{a^x}{a^y}=a^{x-y}$

$$=3x^{1-8}$

$$\frac{6x}{2x^8} =3x^{-7}$

Divide numerator and denominator by the common factor 7, we get

$$\frac{28x^6}{21x^2}=\frac{4x^6}{3x^2}$

Using exponential rule: $\frac{a^x}{a^y}=a^{x-y}$

$$=\frac{4}{3}x^{6-2}$

$$\frac{28x^6}{21x^2}=\frac{4}{3}x^4$

Kristina is four-fifths as old as her sister. Kristina is 12 years old. Write a multiplication equation and solve the equation t

strojnjashka [21]

Answer: Kristina sister's age = 15 years

Step-by-step explanation:

LET the sister's age be rep as x

SO that Kristina = 4/5 of x

Given that Kristina's age = 12 , Then her sister's age can be found using The equation

4/5 x X= 12

4/5 X =12

X = 5 X 12 / 4

=60/4=15

Kristina's sister's age = 15 years.
