Answer:

£32.95

Step-by-step explanation:

36/4=9

Pens= 9×0.75=6.75

36/12=3

Pencils= 3×0.42=1.26

36/6=5

Rulers= 5×1.10=5.5

Pencil cases= 0.54×36=19.44

Altogether:

19.44+5.5+1.26+6.75=32.95

3/4 to the 3rd power

spin [16.1K]

The number 3/4 to the power 3 is equal to 27/64.

Given that the number is 3/4 and we are required to find the value of that number to the power 3.

In mathematics, a power series is basically an infinite series of the form where aₙ represents the coefficient of the nth term and c is a constant.

Number= $(3/4)^{3}$

To find the value of 3/4 to the power 3, we have to multiply 3/4 by 3/4 two times.

$(3/4)^{2}$ =3/4 *3/4 *3/4

=27/64

Hence the number 3/4 to the power 3 is equal to 27/64.

Solve the following system of equations and show all work.<br> y = 2x2<br> y =<br> 3x -1 (10 points)

dedylja [7]

Answer: $\left(\frac{1}{2}, 1 \right), (1, 2)$

Step-by-step explanation:

We have $y=2x^{2}$ and $y=3x-1$ .

Since both of the equations are set equal to y, we can conclude that:

$2x^2 = 3x-1\\\\2x^{2}-3x+1=0\\\\(2x-1)(x-1)=0\\\\x=\frac{1}{2}, 1$

If $x=\frac{1}{2}$ , then $y=3\left(\frac{1}{2} \right)-1=1$

If $x=1$ , then $y=3-1=2$

Therefore, the solutions are $\left(\frac{1}{2}, 1 \right), (1, 2)$

Which of these equations have no solution? Check all that apply.

Llana [10]

2(x + 2) + 2 = 2(x + 3) + 1
2x + 4 + 2 = 2x + 6 + 1
2x + 6 = 2x + 7 - NO SOLUTION
(subtract 2x from both sides, then 6 = 7 FALSE)

2x + 3(x + 5) = 5(x – 3)
2x + 3x + 15 = 5x - 15
5x + 15 = 5x - 15 - NO SOLUTION

4(x + 3) = x + 12
4x + 12 = x + 12 - ONE SOLUTION

4 – (2x + 5) = (–4x – 2)
4 - 2x - 5 = -4x - 2
-2x - 1 = -4x - 2 - ONE SOLUTION

5(x + 4) – x = 4(x + 5) – 1
5x + 20 - x = 4x + 20 - 1
4x + 20 = 4x + 19 - NO SOLUTION
