Two numbers are in the ratio 3:2. if 5 subtracted to each

Mathematics
1 answer:
eduard3 years ago
4 0

Answer:

3 and 2

Step-by-step explanation:

The ratio of the 2 numbers = 3 : 2 = 3x : 2x ( x is a multiple )

When 5 is subtracted from both , that is

3x - 5 : 2x - 5 = 2 : 3

Expressing the ratio in fractional form

\frac{3x-5}{2x-5} = \frac{2}{3} ( cross- multiply )

3(3x - 5) = 2(2x - 5) ← distribute both sides

9x - 15 = 4x - 10 ( subtract 4x from both sides )

5x - 15 = - 10 ( add 15 to both sides )

5x = 5 ( divide both sides by 5 )

x = 1

Thus the 2 numbers are

3x = 3(1) = 3 and 2x = 2(1) = 2

Answer:

Each point reflected across the x-axis, goes from (x, y) --> (x, -y), which means that we keep the x coordinate the same, but multiply the y coordinate by -1:

L (-2, 4) --> (-2, -4)

M (2, 1) --> (2, -1)

N (-4, -3) --> (-4, 3)

Please help!!! I am so confused!
Dafna11 [192]
The first one is c because if you put it at negative 1/8 then it is 0-1/8 or 1/8 away from zero

second one is
the reciprocal is the number that when multiiplied by the number you are trying to find the reciprocal of, you get +1 so the number you have is  2/7 so
2/7 times x=+1
multiply both sdies by 7/2 to clear fraction
x=+7/2
the reciprocal is +7/2 or +3 and 1/2 which is D
