Solve the inequality and graph the solution set on a number line 200-4.5x less then equal to 20

rodikova [14]

ANSWER

$x \geqslant 40$

See graph

EXPLANATION

The given inequality is

$200 - 4.5x \leqslant 20$

Group like terms.

$- 4.5x \leqslant 20 - 200$

$- 4.5x \leqslant - 180$

Divide both sides by -4.5 and reverse the sign of the inequality.

$x \geqslant \frac{ - 180}{ - 4.5}$

$x \geqslant 40$

A snowstorm dropped three and two-fifths inches of snow. The next day one and four-fifths inches melted, how much snow was left?

boyakko [2]

Answer:

After the melting there were one and three fifths of snow left.

Step-by-step explanation:

Given that a snowstorm dropped three and two-fifths inches of snow, and the next day one and four-fifths inches melted, the following calculation must be performed to determine how much snow was left:

2/5 = 0.40

4/5 = 0.80

3.40 - 1.80 = X

1.60 = X

0.60 = 3/5

Thus, after the melting there were one and three fifths of snow left.
