An Easter basket contains eggs of three different colors. Find the total number of eggs in the basket if 2 7 of all eggs are gre
mrs_skeptik [129]

Answer:

Total number of eggs in basket = 56

Step-by-step explanation:

Let z be the total number of eggs

Green eggs = \frac{2}{7} × z   ........1

Blue eggs =  \frac{1}{4} × z    .......2

Rest of eggs = 26  ........3

The addition of 1, 2 and 3 is equal to z  

\frac{2}{7} × z + \frac{1}{4} + 26 = z

\frac{8z + 7 z}{28} + 26 = z                        ∵GCF for 4 and 7 is 28  

\frac{15z}{28}  + 26 = z

15z + (26 × 28) = 28z                ∵ multiply both sides by 28

15z + 728 = 28z

28z - 15z = 728     .......... rearranging above equation

13z = 728  ⇒   z = \frac{728}{13}   ⇒  z = 56

Total number of eggs = z = 56

A cab charges $1.45 for the flat fee and $0.55 for each mile. Write and solve an inequality to determine how many miles Ariel ca
Ugo [173]

Answer:

Step-by-step explanation:

To answer this question you first need to know what the inequality symbols mean!

≤ Less than or equal to

≥ Greater than or equal to

So if Ariel has $35 this mean the following:

$1.45 is the flat fee or y-intercept

$0.55 is the slope

This mean the following:

$1.45 + $ 0.55x ≤ $35

$0.55x ≤ $33.55

x≤61

Determine if each pair of ratios forms a proportion. Show all work! <br><br> 7/C = 35/60
ahrayia [7]

<u>Answer</u>

C = 12


<u>Explanation</u>

Ratio is a division. For the two ratios to be proportional, then they must be the same after been simplified to their simplest form.

7/C = 35/60

35 has been divided by 5 to get 7. 60 must also be dived by 5 for the ratios to be proportional.

60 ÷ 5 = 12

∴ C = 12.


7/12 = 35/60
