In some country's congress, the number of representatives is 25 less than five times the number of senators. there are a total

Nataliya [291]

Let number of senators = x, then:-

number of representatives = 5x - 25 so

x + 5x - 25 = 515
6x = 540
x = 90
number of reps = 515 - 90 = 425

so there are 90 senators and 425 representatives.

Rationalize the denominator and simplify. StartFraction 5 minus StartRoot 3 EndRoot Over 4 plus 2 StartRoot 3 EndRoot EndFractio

nasty-shy [4]

Answer:

$\frac{13-7\sqrt{3}}{2}$

Step-by-step explanation:

We need to rationalize the denominator of $= \frac{5-\sqrt{3}}{4+2\sqrt{3}}$ . For rationalizing we multiply the equation by $\frac{4-2\sqrt{3}}{4-2\sqrt{3}}$

So, solving

$= \frac{5-\sqrt{3}}{4+2\sqrt{3}}*\frac{4-2\sqrt{3}}{4-2\sqrt{3}} \\=\frac{(5-\sqrt{3})(4-2\sqrt{3})}{4+2\sqrt{3}*4-2\sqrt{3}}\\=\frac{(5-\sqrt{3})(4-2\sqrt{3})}{(4)^2-(2\sqrt{3})^2}\\= \frac{5(4-2\sqrt{3})-\sqrt{3}(4-2\sqrt{3})}{16-(4*3)}\\=\frac{20-10\sqrt{3}-4\sqrt{3}+2*3}{16-12}\\=\frac{20+6-14\sqrt{3}}{4}\\=\frac{26-14\sqrt{3}}{4}\\= \frac{2(13-7\sqrt{3})}{4}\\=\frac{13-7\sqrt{3}}{2}$

John wrote the numbers 678,901 and 67,890. How many times greater is the value of 7 in 678,901?

worty [1.4K]

Answer:

The value of 7 in 678,901 is 10 times greater than the value of 7 in 67,890

Step-by-step explanation:

step 1

we have

678,901

Write in expanded form

678,901=600,000+70,000+8,000+900+1

The value of 7 is 70,000

step 2

we have

67,890

Write in expanded form

67,890=60,000+7,000+800+90

The value of 7 is 7,000

step 3

Divide 70,000 by 7,000

$\frac{70,000}{7,000}=10$

therefore

The value of 7 in 678,901 is 10 times greater than the value of 7 in 67,890
