Answer:

-11≤x

Step-by-step explanation:

Given

6.7 ≥ -0.2x +4.5----------------collect like terms

6.7-4.5 ≥ -0.2x--------------divide by -0.2 both sides

2.2/-0.2 ≥ -0.2/-0.2x-------------------reverse the sign

-11 ≤ x

For this case we have the following inequality:

6.7\geq 0.2x + 4.5

Subtracting 4.5 from both sides of the inequality:

6.7-4.5\geq -0.2x\\2.2\geq -0.2x

Dividing between 0.2 on both sides:

\frac {2.2} {0.2} \geq-x\\11 \geq-x

We multiply by -1 on both sides, taking into account that the sense of inequality changes:

-11 \leq x

ANswer:

x \geq-11

The weight of mr nazeer is 7 times that of his son. What's the ratio of their weights?
Mekhanik [1.2K]

Answer:

<h3>7:1</h3>

Step-by-step explanation:

Let the weight of mr nazeer be x

Let the weight of his son be y

If the weight of mr nazeer is 7 times that of his son, then x = 7y

To get the ratio of their weight:

Ratio = weight of father/weight of son

Ratio = 7y/y

Ratio = 7/1

Ratio = 7:1

Hence the ratio of their weights is 7:1
