What are three ratios equal to 4 over 28 .simplify if needed?

SVETLANKA909090 [29]

4/28 = 1/7 when dividing both numerator & denominator by 4 and this would be the simplified fraction.

You could use 1/7 to multiply with others to get other ratios that are equal to 4/28 or you could just use 4/28.

For example:
1/7 = 7/49
or
4/28 = 8/56

use the elimination method to solve the system of equations choose the correct ordered pair 7x+4y=39 2y+4y=14

Anvisha [2.4K]

$x = 5 \: and \: y = 1.$

Step-by-step explanation:

$7x + 4y = 39 \: - {eq}^{n} (1)$

$2x + 4y = 14 \: \: - {eq}^{n} (2)$

Multiply Equation no (1) with 2 and Equation no (2) with 7.

$14 x + 8y = 78.$

$14x + 28y = 98.$

$( - ) \: \: \: ( - ) \: \: \: ( - )$

$0x + -20y = - 20$

$- 20y = - 20$

$y = \frac{ - 20}{ - 20}$

$y = 1$

Substitute the value of "y" in Equation no (1)

$7x + 4y = 39.$

$7x + 4(1) = 39.$

$7x + 4 = 39.$

$7x = 39 - 4$

$7x = 35.$

$x = \frac{35}{7}$

$x = 5.$
