-2x + 4 < 16
Help me please I didn’t pay attention

Answers

Answer 1

Answer:

I think it’s done like this, I’m not sure

First, collect the like terms

-2x<16-4

-2x<12

x<12/-2

x<-6

So, you substitute -6 instead of x to find which is greater

12+4<16

16<16

Which makes it false

Step-by-step explanation:

I hope I explained well, please give me brainliest

Answer 2

The solution of the inequality - 2x + 4 < 16 will be;

⇒ - 6 < x

What is Inequality?

A relation by which we can compare two or more mathematical expression is called an inequality.

Given that;

The inequality is,

⇒ - 2x + 4 < 16

Now,

Solve the expression as;

⇒ - 2x + 4 < 16

Subtract 4 both side, we get;

⇒ - 2x + 4 - 4 < 16 - 4

⇒ - 2x < 12

Divide by 2 , we get;

⇒ - x < 6

Multiply by - 1, we get;

⇒ x > - 6

⇒ - 6 < x

Thus, The solution of the inequality - 2x + 4 < 16 will be;

⇒ - 6 < x

-4x-y=24 missing value

Answers

Answer:

For solving x         x= -24+y/4  For solving Y                y=−24−4x

Step-by-step explanation:

This is solving for x

Add y to both sides.

−4x=24+y

Divide both sides by -4

and the answer is

x= -24+y/4

THis is solving Y

Add 4x to both sides

−y=24+4x

Multiply both sides by -1

and the answer is  

y=−24−4x

2.5(a + 4) + 0.5a = 12.4

Answers

Answer:

a=0.8

Step-by-step explanation:

First I distributed 2.5 into (a+4) and got (2.5a+10)+0.5a=12.4. I then combined like terms which are 2.5a and 0.5a and got 3a+10=12.4. I subtracted 10 from both sides to get rid of it and got 3a=2.4. Later, I divided 3 from both sides to get a which comes out to be 0.8.

4. A student buys a movie to watch on her phone, but she's worried about the
amount of storage space downloading it will take up. She starts the download and
notices it will download at a constant rate. After 3 minutes, she checks her phone
and sees that she has 2,345 MB of space available. She checks her phone after 7
minutes and notices that she now has 2,105 MB of space available.
(a) How many MB of available storage are being filled by the movie per minute?

Answers

Answer:

240

Step-by-step explanation:

by minusing the both values it'll be 240

The rate at which the storage space of the mobile gets filled by the movie is - 60 MB per minute.

Given that,
A student buys a movie to watch on her phone
it will download at a constant rate.
After 3 minutes, she checks her phone and sees that she has 2,345 MB of space available.
She checks her phone after 7 minutes and notices that she now has 2,105 MB of space available.

What is the rate of change?

The rate of change is defined as the change in value with the rest of the time is called rate of change.

Here,


Rate = (storage available after 3 minutes) - (storage available after 7 min)]
             ---------------------------------------------------------------------------------------------
                                              Time interval

Rate = (2,345 - 2105 ) / (3 - 7)
Rate = - 240 / - 4
Rate = - 60

Where negative sign shows that the amount of storage getting reduced.

Thus, the rate at which the storage space of the mobile gets filled by the movie is - 60 MB per minute.

Bob runs a total of 12 miles each week. He wants to increase the number of miles he runs each week by 1.5 miles until he is running a total of 26 miles each week. Provide an equation that can be used to determine the number of weeks Bob will need to reach his goal

Answers

Answer:

The equation is 12 + 1.5w = 26

Step-by-step explanation:

Each week running = 12 miles

He wants to increase the number of miles he runs each week by 1.5 miles until he is running a total of 26 miles each week.

12 + 1.5w = 26

Where,

w = number of weeks to reach his goal

12 + 1.5w = 26

1.5w = 26 - 12

1.5w = 14

Divide both sides by 1.5

w = 14 / 1.5

= 9.33 weeks

A student ate 3/20 of all the candy and another 1.2 lb. Another student ate 3/5 of the candy and the remaining 0.3 lb. What was the total weight of the candy they ate?

Answers

Answer:

x = 6 lb

Step-by-step explanation:

Let

Total weight of the candy = x

3/20x + 1.2 lb + 3/5x + 0.3 lb = x

3/20x + 3/5x + 1.5 lb = x

3x+12x/20 + 1.5 lb = x

15/20x + 1.5 = x

1.5 = x - 15/20x

1.5 =20x -15x /20

1.5 = 5/20x

1.5 = 1/4x

x = 1.5 ÷ 1/4

= 1.5 × 4/1

The shortest side of a right triangle is 14 inches long. The difference between the lengths of the other two sides is 2 inches. Find the missing sides. Use exact values.

Answers

Answer:

The missing sides are 50 inches and 48 inches long.

Step-by-step explanation:

Let the lengths of the other two sides be x inches and y inches

And let x represent the length of the longest side.

From the question,

The difference between the lengths of the other two sides is 2 inches. That is,

x - y = 2 ...... (1)

The three sides of the right triangle are x, y, and 14 inches long.

From the Pythagorean theorem, " In a right triangle, the square of the longest side equals sum of squares of the other two sides"

Here, the longest side is x

Hence, we can write that

x² = y² + 14²

∴ x² = y² + 196 ...... (2)

Now, we have two equations, we can then solve simultaneously.

From equation (1)

x - y = 2

∴ x = y + 2 ...... (3)

Put this into equation (2)

x² = y² + 196

(y+2)² = y² + 196

y² + 4y + 4 = y² + 196

4y + 4 = 196

4y = 196 - 4

4y = 192

y = 192/4

y = 48

To determine x, we will substitute the value of y into equation (3)

x = y + 2

∴ x = 48 + 2

x = 50

Hence, x = 50 and y = 48

Since the lengths of the other two sides are x inches and y inches,

Hence, the missing sides are 50 inches and 48 inches.
