Select two ratios that are equivalent to 27:927:927, colon, 9. Choose 2 answers: Choose 2 answers: (Choice A) A 3:13:13, colon,

Troyanec [42]

Answer:

A. $Ratio = 3:1$

B. $Ratio= 9:3$

Step-by-step explanation:

Given

$Ratio= 27:9$

Required

Determine equivalent ratios:

$Ratio= 27:9$

First, we simplify the ratio to the least possible

$Ratio = 27/9:9/9$

$Ratio = 3:1$

By comparison with the given options, we have A and B as answer.

See Proof Below

Proof: A

Compare this to the simplified ratio (given), we have:

$Ratio = 3:1$ = $Ratio = 3:1$

Proof B

$Ratio= 9:3$

Simplify the ratio to the least possible

$Ratio= 9/3:3/3$

$Ratio= 3:1$

Compare this to the simplified ratio (given), we have:

$Ratio = 3:1$ = $Ratio = 3:1$

Y * x = 20<br><br> y + x = 9 <br><br> what numbers are y and x equal to?

Ksivusya [100]

$y = 9 - x$
Substitute into
$y \times x = 20 \\ (9 - x) \times x = 20 \\ { - x}^{2} + 9x = 20 \\ {x}^{2} - 9x + 20 = 0 \\ (x - 5)(x -4) = 0 \\ x = 5 \: or \: x = 4$
When x = 5,
$y = 9 - 5 \\ y = 4$
When x = 4,
$y = 9 - 4 \\ y = 5$

x = 5, y = 4
x = 4, y = 5

Hope this helps. - M
