Answer:

Step-by-step explanation:

£9.90 = 990p

x is number of 50p stamps

2x* 20 + x* 50 = 990

40x+50x = 990

90x = 990

x = 11

2x = 22

11 50p stamps

22 20p stamps

check:

11*50+22*20 = 550 + 440 = 990

Bobs hardware sells buckets in 5 different sizes. The tiny bucket holds 5 quarts, the small holds 10 quarts, the medium holds 20

Sphinxa [80]

Bob's hardware sells buckets in five different sizes.

The tiny bucket holds 3 quarts,

The small bucket holds 6 quarts,

The medium bucket holds 12 quarts,

The large bucket holds 24 quarts and

There is a relation between the size of the bucket and its volume.

We could see with increase in size the units of quarts double

Therefore the extra large bucket will hold 24*2 = 48 quarts

Solve the proportion. a. 4/x = 9 b. 7.5/26 = 75/p

lina2011 [118]

<u>ANSWER: </u>

The values of x and p after solving given equations are 0.445 or $\frac{4}{9}$ and 260 respectively..

<u>SOLUTION: </u>

Given, two proportions are $\frac{4}{x}$ =9 and $\frac{7.5}{26} = \frac{75}{p}$

We need to solve the given two proportions.

Let us solve the first proportion, $\frac{4}{x}$ = 9

$\frac{4}{x} = \frac{9}{1}$

On cross-multiplication, we get

4 $\times$ 1 = 9x

4 = 9x

x = $\frac{4}{9}$

x = 0.445

Now, let us solve the second proportion $\frac{7.5}{26} = \frac{75}{p}$

$\frac{\frac{75}{10}}{26}=\frac{75}{p}$

$\frac{75}{10 \times 26} = \frac{75}{p}$

$\frac{1}{260} = \frac{1}{p}$

On cross-multiplication, we get

p = 260

Hence, the values of x and p after solving given equations are 0.445 and 260 respectively.

Using radicals, write an equivalent expression for the expression y^1/5

Mkey [24]

Answer:

$\large\boxed{y^\frac{1}{5}=\sqrt[5]{y}}$

Step-by-step explanation:

$\text{Use}\ a^\frac{m}{n}=\sqrt[n]{a^m}\to a^\frac{1}{n}=\sqrt[n]{a}\\\\y^\frac{1}{5}=\sqrt[5]{y}$

sweet-ann [11.9K]

[tex]15000= \frac{5}{7}*x[\tex]
[tex]x=15000* \frac{7}{5}=21,000[\tex]

Check 21,000 * 2/7 = 6.000 and 6,000 + 15,000 = 21,000
