Ryan is trying a low-carbohydrate diet. He would like to keep the amount of carbs consumed in grams between the levels shown in the following compound inequality: 110 < 2x + 10 and 2x + 10 < 310 Solve for x in this inequality, and explain what the answer represents.

Answers

Answer:

[tex]50<x<150[/tex]

Ryan would like to eat more than 50 carbs per day, but no more than 150 carbs per day.

So, Ryan's total carb intake must be between 50 and 150 carbs.

Step-by-step explanation:

So he wants to keep his consumption of carbs between the inequalities:

[tex]110<2x+10\text{ and } 2x+10<310[/tex]

So, let's solve both inequalities.

1)

[tex]110<2x+10[/tex]

Subtract 10 from both sides:

[tex]100<2x[/tex]

Divide both sides by 2:

[tex]50<x[/tex]

2)

[tex]2x+10<310[/tex]

Subtract 10 from both sides:

[tex]2x<300[/tex]

Divide both sides by 2:

[tex]x<150[/tex]

So, our inequality is now:

[tex]110<2x+10\text{ and } 2x+10<310[/tex]

Since we solved the equations:

[tex]50<x\text{ and } x<150[/tex]

Written as a compound inequality, this is:

[tex]50<x<150[/tex]

In other words, Ryan would like to eat more than 50 carbs per day, but no more than 150 carbs per day.

So, Ryan's total carb intake must be between 50 and 150 carbs.

Which equation can be represented using the number line?

A number line going from to 1 in increments of one-eighths. Arrows go from each mark on the line to the next up to three-fourths.
Three-fourths divided by one-eighth = 6
One-eighth divided by three-fourths = 6
6 divided by three-fourths = one-eighth
6 divided by one-eighth = three-fourths

Answers

Answer:

a

Step-by-step explanation:

The equation which can be represented using the picture displayed on the number line is Three-fourths divided by one-eighth = 6

The distance between each marked line on the number line is 1/8

The length of the number line is 3/4

The number of steps or marked points can be obtained using the relation :

Length of line ÷ Distance between each marked points

3/4 ÷ 1/8 = 6

Therefore, the expression which represents the scenario on the number line is 3/4 ÷ 1/8 = 6

SOMEONE PLS HELP ME ASAPPP: The odometer of a vehicle tells you how far it has traveled in its lifetime. The "trip odometer" can be reset at any time to tell you the length of a particular trip. Suppose the main odometer of a new car is at 467 miles and the trip odometer is at 22 miles. How many more miles do you have to travle before the main odometer is precisely two times the trip odometer?

Answers

Answer:

423 miles

Step-by-step explanation:

x - the miles to travel

467+x - the main odometer after x miles travel

22+x - the trip odometer after x miles travel

2(22+x) - two times the trip odometer after x miles travel

2(22+x) = 467 + x

44 + 2x = 467 + x

- 44 -44

2x = 423 + x

-x -x

x = 423
