Answer:

9 boxes

Step-by-step explanation:

Boxes of Cereal 3 for the price of 2, the the price of the 3 boxes of cereals must be : 2 × £2.89 = £5.78

Boxes Megan can buy for the offer = £20 ÷ £5.78  = 3.46 (to 3 s.f.)≈ 3

3 × 3 =9 packs

But they actually only cost : 3 × £5.78  = £17.34

Therefore after buying the offer Megan has £20 - £17.34 = £ 2.66 left, which is not enough to buy a single pack, so the answer is 9.

Step-by-step explanation:

Answer:

y = -7

Step-by-step explanation:

If x equals -14 then you would plug it in and the equation would be -2(-14)-3y=49

The new equation would be 28-3y=49

Then you would subtract 28 from both sides and get -3y=21

Lastly you would divide both sides by -3 and get y=-7

Answer:

R = (- 3, 8 )

Step-by-step explanation:

Using the midpoint formula , equate the coordinates to the corresponding coordinates of Q.

let R = (x, y ) , then

[tex]\frac{1}{2}[/tex] (x + 11 ) = 4 ( multiply both sides by 2 )

x + 11 = 8 (subtract 11 from both sides )

x = - 3

[tex]\frac{1}{2}[/tex] (- 2 + y) = 3 ( multiply both sides by 2 )

- 2 + y = 6 ( add 2 to both sides )

y = 8

Thus

R = (- 3, 8 )

The coordinates of R = (c, d) is (-3, 8).

Given,

Q is the midpoint of PR.

P(11, -2) and Q(4,3).

We need to find the coordinates of R

If (x,y) is the midpoint between two points (a,b) and (c,d) then we use the formula:

x = (a + c) / 2 and y = (b + d) / 2

Find the coordinates of point P.

Let the coordinates of P be (a, b)

= (a, b)

= (11, -2)

Find the coordinates of point Q.

Let the coordinates of Q be (x, y)

= (x, y)

= (4, 3)

Find the coordinates of point R.

Let the coordinates of R be ( c, d)

= (c, d)

Find the coordinates of R.

We have,

x = (a + c) / 2

4 = (11 + c) / 2

4 x 2 = 11 + c

8 = 11 + c

c = 8 - 11

c = -3

y = (b + d) / 2

3 = (-2 + d) / 2

3 x 2 = -2 + d

6 + 2 = d

d = 8

We get,

R = (c, d) = (-3, 8)

Thus the coordinates of R = (c, d) is (-3, 8).

The Division of (7/3) ÷ (2/9) gives 21/2.

The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.

Given:

Divide 7/3 by 2/9

So, (7/3) ÷ (2/9)

= 7/3 x 9/2

= 7 x 3/2

= 21/2

Hence, the division results to 21/2.
