Answer:

f(3)=1

Step-by-step explanation:

take f(x)=2(x)-5

put a three wherever you see an x in parentheses

f(3)=2(3) - 5

simplify

f(3)=6-5

simplify

The density of a certain material is such that it weighs 70 pounds for every 8.5 gallons of volume. Express this density in kilo
STALIN [3.7K]

The correct answer is 0.99kg/L

Explanation:

To find the density, the first step is to convert the weight (mass) and the volume into the appropriate units.

The volume is 8.5 gallons and this needs to be converted to litters. In this case, multiply the volume in gallons by 3.785 because each gallon contains 3.785 liters.

8.5 x 3.785 = 32.1725 liters

The mass is 70 pounds and this needs to be converted to kilos. In this case, divide the pounds by 2.204 considering each kilo contains 2.204 pounds.

70 ÷ 2.2046 = 31.751 kilos

Now, find the density by dividing the mass into the volume.

Density= 31.751 kg ÷ 32.1725 L

Density = 0.98 kg/L

This means the density is 0.9.868 kg/L and this can be rounded as 0.99 kg/L

Write a problem situation to match the inequality: x divided by 4 less than or equal to 5
Paha777 [63]

Answer:

yes it is ill explain

Step-by-step explanation:Find the student's error in solving the following inequality.31 < -5x + 625 < -5x-5 < x

The student should have added 6 to both sides instead of subtracting it.

The student divided 25/-5 incorrectly.

The student should have switched the direction of the inequality sign to get -5> x for a final answer.

The student should have switched the direction of the inequality sign to get -5> x for a final answer.

Find the student's error in solving the following inequality.2 < -3x -4 < 56 < -3x < 5-2 > x > -5/3

The student should have added 4 to all parts (left, middle, and right) to get 6 < -3x < 9.

The student divided 6/-3 incorrectly.

The student should not have switched the direction of the sign in the final step.

The student should have added 4 to all parts (left, middle, and right) to get 6 < -3x < 9.

Which numbers are solutions to the inequality 2x - 1 > x + 2? Check all of the boxes that apply.

4, 5

If x < 5 and x > c, give a value of c such that there are no solutions to the compound inequality. Explain why there are no solutions

Sample response: The value of c could be 5 or any number greater than 5.

The solution is the intersection of both solution sets of the given inequalities.

The solutions of the compound inequality must be solutions of both inequalities.

A number cannot be both less than 5 and greater than 5 at the same time.

Identify the graph of the inequality 2(2x - 1) + 7 < 13 or -2x + 5 -10.
