Please help me with question2 someone, thanks

Minchanka [31]

Answer:

Step-by-step explanation:

$\frac{3x-y}{4x+5y}=\frac{3}{5}\\\\$

Cross multiply

5*(3x-y) = 3*(4x + 5y)

5*3x -5*y = 3*4x + 3*5y

15x - 5y = 12x + 15y

15x - 12x = 15y + 5y

3x = 20y

3x = 4y * 5

$\frac{3x}{4y} = 5$

Anybody know how to do lowest terms and can teach me how to get the answer to lowest terms questions?

Rzqust [24]

Answer:

Step-by-step explanation:

6/9+x=7/10

x=7/10-6/9

when adding fractions both denominators must be equal, we’ll make them 90

x=(7/10)(9/9)-(6/9)(10/10)

x=63/90-60/90

x=3/90, the greatest divisor of 3 and 90 is 3 so divide both the numerator and denominator by 3

x=(3/3)/(90/3)

x=1/30

Value of m varies directly as value of n and n=5 when m=12. What is n when m=18?

Shkiper50 [21]

Simplify the problem down, so:

m = 12 & n = 5
m = 6 & n = 2.5 (divided each number by 20)

Now m is a factor of 18. Multiply each number by 3.
Answer: m = 18 & n = 7.5
