Answer:
Total number of eggs in basket = 56
Step-by-step explanation:
Let z be the total number of eggs
Green eggs =
× z ........1
Blue eggs =
× z .......2
Rest of eggs = 26 ........3
The addition of 1, 2 and 3 is equal to z
× z +
+ 26 = z
+ 26 = z ∵GCF for 4 and 7 is 28
+ 26 = z
15z + (26 × 28) = 28z ∵ multiply both sides by 28
15z + 728 = 28z
28z - 15z = 728 .......... rearranging above equation
13z = 728 ⇒ z =
⇒ z = 56
Total number of eggs = z = 56

Step-by-step explanation:
<span>2√7 - (-8√7) - 3√7 = </span><span>2√7 + 8√7 - 3√7 = (2 + 8 - 3)</span><span>√7 = 7</span><span>√7</span>
A properly written number in scientific notation has the form:
+/- A*10^n
where +/- is either plus or minus
A is a decimal number (or integer) where 1<= A < 10
and n is a positive or negative integer.
According to these rules,
120,000,000 is written in scientific notation as
1.2 * 10^8
so we need to move the decimal point 8 places to the left and multiply by 10^8.
