Answer:  one Apple costs £ 0.20, and one banana costs £ 0.60

Step-by-step explanation:

let x = the amount of apples

let y = the amount of bananas

4x + y = 1.40

7x + y = 2

this is à system of equations

simplify the top equation to   y = 1.4 - 4x

now plug that into the second equation and solve

7x + 1.4 - 4x = 2

3x + 1.4 = 2

3x = 0.6

x = 0.2

that means that one Apple costs £ 0.20

plug that back into the top equation

4x + y = 1.4

4(0.2) + y = 1.4

0.8 + y = 1.4

y = 0.6

so one banana costs £ 0.60

Sergio [31]

Answer:

D. Batch 5.

Step-by-step explanation:

The batch should have the same proportion of blue to white to yellow.

In Batch 1, there are two parts of blue, 1.5 parts of white, and 1 part of yellow.

In Batch 5, there are four parts of blue, 3 parts of white, and 2 parts of yellow.

4 / 2 = 2

3 / 2 = 1.5

2 / 2 = 1

Since the proportions are equal to those found in Batch 1, D. Batch 5 will create the same colors as the first batch.

Hope this helps!

-2 4/5 + 1/4 equals what ?
vlada-n [284]
Hey there! :)

Since 2 4/5 is greater than 1/4, the answer is negative.

You can just subtract 2 4/5 and 1/4 and add the (-) sign

2 4/5 - 1/4

Change the fractions so they can have a common denominator: 20

2 4/5 = 2 16/20

1/4 = 5/20

2 16/20 - 5/20 = 2 11/20

Add the (-) sign → -2 11/20

Answer ⇒ -2 11/20

malfutka [58]

<u>Answer</u>:

18 clips for $7.38 is the best value deal.

<u>Step-by-step explanation:</u>

An office is restocking office supplies. The table below shows the cost for the number of boxes of paperclips. We need to find what is the best value is.

To find the best value for money we can check the price of each paperclip.

To check the price of each paper clip we can use the following formula:

\text{Price of each paper clip} =\frac{\text { price of the box }} {{\text {number of clips in the box }}}

Now we can calculate the best value deal as follows:

\text{Price of each clip is box 1}=\frac{7.38}{18}=0.41$

\text{Price of each clip is box 2}=\frac{15.39}{27}=0.57$

\text{Price of each clip is box 3}=\frac{13.50}{30}=0.45$

\text{Price of each clip is box 4}=\frac{18.36}{36}=0.51$

\text{Price of each clip is box 5}=\frac{18.80}{40}=0.47$

So, from looking at the prices of each paperclip we can conclude that the 18 clips for $7.38 is the best value deal.
