5n + 1 = 5n - 1

Subtract 5n from both sides.

1 = -1

This is a FALSE statement, so that means your answer is:

<h3>No solution</h3>

Please answer me this question

Jobisdone [24]

Answer:

x = 2

y = 3

Step-by-step explanation:

$\left \{ {{0.4x + 0.3y = 1.7} \atop {0.7x - 0.2y = 0.8}} \right.$

$\left \{ {{2(0.4x + 0.3y) = 2 * 1.7} \atop {3(0.7x - 0.2y) = 3 * 0.8}} \right.$

$\left \{ {{0.8x + 0.6y = 3.4} \atop {2.1x - 0.6y) = 2.4}} \right.$

$2.9x = 5.8$

$29x = 58$

$x = 2$

$0.3y + 0.4x = 1.7$

$0.3y + 0.4 * 2 = 1.7$

$0.3y + 0.8 = 1.7$

$0.3y = 0.9$

$3y = 9$

$y = 3$

*I thought of a number, added 18, then multiplied the result by 8. I got 16. What was my number?

Arte-miy333 [17]

Answer:

-16

Step-by-step explanation:

Represent the number by n.

Then:

8(n + 18) = 16

Performing the indicated multiplication, we get:

8n + 144 = 16

Subtracting 144 from both sides results in 8n = -128.

Dividing both sides by 8: n = -128/8 = -16

The number was -16.

In Cecilia’s CD collection, 1/5 of her Jazz CDs represents 1/10 of all her CDs. What is the ratio of her Jazz CDs to her non-Jaz

KatRina [158]

Answer: The required ratio is 1:1.

Step-by-step explanation:

Let the total number of CDs be 100

$\frac{1}{10}$ of CDs is given by

$\frac{1}{10}\times 100\\\\=10$

According to question,

$\frac{1}{5}$ of her Jazz CDs represents $\frac{1}{10}$ of all her CDs.

Let the number of Jazz CDs be x

So, it becomes

$\frac{1}{5}\times x=10\\\\x=10\times 5\\\\x=50$

So, Number of Jazz's CDs is 50

Number of Jazz non CDs is given by

$100-50=50$

Ratio of her CDs to her non- CDs is given by

$50:50\\\\1:1$

Hence, the required ratio is 1:1.
