Help me please with this
Nutka1998 [239]

Answer:

a

Step-by-step explanation:

Solving the inequality

\frac{x+3}{6} > \frac{x}{4} + 1

Multiply through by 12 ( the LCM of 6 and 4 ) to clear the fractions

2(x + 3) > 3x + 12

2x + 6 > 3x + 12 ( subtract 2x from both sides )

6 > x + 12 ( subtract 12 from both sides )

- 6 > x , that is

x < - 6

The only value less than - 6 is - 10

Thus x = - 10 is a solution to the inequality

X:y=5:3 and x+y=56<br> what is the value off x-y
Rudiy27

x:y=5:3\to\dfrac{x}{y}=\dfrac{5}{3}\qquad\text{cross multiply}\\\\3x=5y\qquad\text{divide both sides by 3}\\\\x=\dfrac{5}{3}y\\\\\text{substitute to the equation} \ x+y=56\\\\\dfrac{5}{3}y+y=56\\\\\dfrac{5}{3}y+\dfrac{3}{3}y=56\\\\\dfrac{5+3}{3}y=56\\\\\dfrac{8}{3}y=56\qquad\text{multiply both sides by 3}\\\\8y=3\cdot56\qquad\text{divide both sides by 8}\\\\y=3\cdot7\\\\y=21\\\\\text{substitute the value of y to the equation}\ x=\dfrac{5}{3}y\\\\x=\dfrac{5}{3}\cdot21=5\cdot7=35
