Hey there! :D

Since Carol has 100 stamps, the percentages are like whole numbers.

24%= 24 stamps

22%= 22 stamps

25%= 25 stamps

29%= 29 stamps

This is only because she has 100, and the percentages are from 100. If it was 50, it would be much different. You would multiply .25 by 50 for the number of stamps. It was nice that it was 100.

So, now we just find Italy and England and subtract them.

25-22= 3

3 stamps. <== the answer

I hope this helps!

If x+1/x = 5 find the value of x^3 +1/x^3. pls solve

Korolek [52]

Answer:

1) solve x+1/x = 5

$\frac{x + 1}{x} = 5$

$x + 1 = 5x$

$x - 5x = - 1$

$- 4x = - 1$

$x = \frac{ -1}{ - 4}$

$x = \frac{1}{4}$

2) solve x³+1/x³

$x {}^{3} + \frac{1}{x {}^{3} }$

substitute x = 1/4 into the expression

$( \frac{1}{4} ) {}^{3} + \frac{1}{( \frac{1}{4}) {}^{3} }$

$\frac{1}{64} + \frac{1}{ \frac{1}{64} }$

$\frac{1}{64} + \frac{64 \times 1}{1}$

$\frac{1}{64} + 64$

$\frac{4097}{64} \: or \: 64.02$

99 pencils cost \$7.74$7.74dollar sign, 7, point, 74. Which equation would help determine the cost of 666 pencils? Choose 1 answ

balu736 [363]

Answer:

$\large \boxed{\text{A) } \dfrac{6}{x} = \dfrac{9}{\$7.74}}$

Step-by-step explanation:

9 pencils cost $7.74

6 pencils cost x

The ratios are

$\dfrac{9}{6} = \dfrac{\$7.74}{x}$

According to the alternendo property,

$\dfrac{9}{6} = \dfrac{\$7.74}{x} \Rightarrow \dfrac{9}{\$7.74} = \dfrac{6}{x}\\\\\text{The correct answer is $\large \boxed{\mathbf{ \dfrac{6}{x} = \dfrac{9}{\$7.74}}}$}$
