Answer:

Step-by-step explanation:

4(3) -(-6)

4 times 3 is 12. When you subtract a negative number the negative number gets added so it would be 12 + 6 which is 18. Hope that helps :)

While mining, Keith found a large metal bar that weighed 42 ounces. Keith was also able to determine that the bar had 30 ounces

Usimov [2.4K]

Divide the silver present in the bar by the total weight of the bar to find the percentage of silver in the bar.

$30 / 42 = 0.7142$

Multiply this decimal by 100 for the percentage.

$.7142 * 100 = 71.42$

Rounded to the nearest tenth, 71.4% of the weight of the bar is silver.

"Bobby, you should know that the minimum legal speed for this highway is 45 MPH, and the maximum legal speed is 65 MPH."

Ket [755]

Inequalities help us to compare two unequal expressions. The inequality that represents the given statement is 45≤x≤ 65.

<h3>What are inequalities?</h3>

Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed.

It is mostly denoted by the symbol <, >, ≤, and ≥.

Given the maximum legal speed on the highway is 65 MPH, therefore, the value of x must not exceed 65 MPH.

x ≤ 65

Also, the minimum legal speed on the highway is 45 MPH, therefore, the value of x must not be less than 45 MPH.

45≤x

By combining the two inequalities, we will get,

45≤x≤ 65

Hence, the inequality that represents the given statement is 45≤x≤ 65.

The complete question is:

Write an inequality that accurately represents the following statement: "Bobby, you should know that the minimum legal speed for this highway is 45 MPH, and the maximum legal speed is 65 MPH."
