The ratio of two numbers is 4:9. When 5 is subtracted from each of them the new ratio becomes 3:8. Find the numbers.

natta225 [31]

Answer:

FIRST NUMBER IS 20

AND

SECOND NUMBER IS 45

Step-by-step explanation:

LET THE RATIO BE X

FIRST NUMBER = 4X

SECOND NUMBER = 9X

A/Q,

=}4X - 5 / 9X - 5 = 3 / 8

CRISS CROSS,

=}8 ( 4X - 5 ) = 9X - 5 ( 3 )

=}32X - 40 = 27X - 15

=}32X - 27X = - 15 + 40

=}5X = 25

=}X = 25 / 5

=}X = 5

THEREFORE,

FIRST NUMBER

=} 4X

=} 5 × 4

=} 20

SECOND NUMBER

=} 9X

=} 5 × 9

=} 45

Write the standard form of the equation y+4=12/7(x-1)

Goshia [24]

This is the eqn of a str line. y+4=12/7(x-1) would be clearer if written as

y+4=(12/7)(x-1). y+4 = (12/7)x - 12/7.

Multiply all terms by 7 to remove the fractions: 7(y+4) = 12x - 12.

Complete the multiplication: 7y + 28 = 12x - 12.

Arrange the x and y terms on the left side and the constants on the right:

-12x + 7y = -40. This is standard form. Some people might disagree and say that -12x + 7y + 40 is standard form. They are equivalent.
