(7 x 10 ^5) + (4 x 10 ^2)

spayn [35]

$\huge\text{Hey there!}$

$\mathsf{(7\times 10^5) + (4 \times 10^2)}\\\mathsf{= 7\times 10^5 + 4 \times 10^2}$

$\large\textsf{Let's solve for the LEFT SIDE first}$

$\mathsf{7\times 10^5}\\\\\mathsf{10^5}\\\mathsf{= 10\times10\times10\times10\times10}\\\mathsf{= 100 \times 100\times 10}\\\mathsf{= 10,000 \times 10}\\\mathsf{= 100,000}\\\\\mathsf{7\times100,000}\\\mathsf{= 700,000}$

$\large\textsf{NEW EQUATION: }\bold{700,000} + {4}\times 10^2$

$\large\textsf{Now, let's solve for the RIGHT SIDE last}$

$\mathsf{4\times 10^2}\\\\\mathsf{10^2}\\\mathsf{= 10\times10}\\\mathsf{= 100}\\\\\mathsf{4\times100}\\\mathsf{= 400}$

$\large\text{NEW EQUATION: 700,000 + \bf 400}$

$\large\text{700,000 + 400}\\\\\large\text{SIMPLIFY IT!}\\\\\large\text{= 700,400}$

$\huge\text{Therefore, the answer should be: \boxed{\mathsf{700,400}}}\huge\checkmark$

BlackZzzverrR [31]

Answer:

$y=6\\x=6$

Step-by-step explanation:

$3x+5y=48$

$-3x+5y=12$

sum the two equations

$10y=60\\y=6\\3x+5y=48\\3x=48-5*6\\x=6\\$

The number of birds on each of the islands X and Y remains constant from year to year; however, the birds migrate between island

Tasya [4]

Answer: Option 'b' is correct.

Step-by-step explanation:

Since we have given that

Total number of birds = 14000

Let the number of birds on X be 'x'.

Let the number of birds on y be 14000-x

After one year, 20 percent of the birds on X have migrated to Y, and 15 percent of the birds on Y have migrated to X.

but The number of birds on each of the islands X and Y remains constant from year to year.

So, the equation would be

$\dfrac{20}{100}x=\dfrac{15}{100}(14000-x)\\\\0.2x=0.15(14000-x)\\\\0.2x=2100-0.15x\\\\0.20x+0.15x=2100\\\\0.35x=2100\\\\x=\dfrac{2100}{0.35}=6000$

Hence, there are 6000 birds on island X.

Hence, Option 'b' is correct.
