Solve this inequality (show your work)

3x -7 > 5

Answers

Answer 1

Answer:

x > 4

Step-by-step explanation:

if x were to equal 4, then we would have 12 - 7 > 5 which when we simplify it, we know it's not true because it would be 5 > 5 which is incorrect. That means that the lowest number x could possibly be is 5 because when substituted and simplified, we get 8 > 5 which is correct. The answer I put means that x has to be greater than 4 because if x was any number greater than 4, it would make the inequality true.

(sorry if this is confusing, I'm not really good at explaining things. I hope it helped anyway)

Answer 2

Answer:

x>4

Step-by-step explanation:

When solving an inequality, treat it exactly like you would when solving an equation. Perform reverse operations on both sides of the inequality to cancel values out and isolate the variable, which in this case, is x. The only difference is if you were to multiply or divide both sides by -1, you must reverse the inequality (ex. > turns into <)

[tex]3x -7 > 5[/tex]

Add 7 to both sides    

[tex]3x -7+7>5+7\\3x>12[/tex]

Divide both sides by 3

[tex]\frac{3x}{3}>\frac{12}{3}\\x>4[/tex]

I hope this helps!

Write an expressions for the missing dimension of each shaded figure and a multiplication expression for it's area

Answers

Answer:

alrighty then, x has to be 14, so x-3=11 which means the question mark would be 3. you can do the rest yourself, I believe in you!

Step-by-step explanation:

To solve this problem, we are required to write and expression to solve for the missing side in each figure.

Side of a Square

To find the missing side of the square, we can simply write it as

[tex]15 = h + x\\x = (15 - h)m[/tex]

For the triangle, to find the missing side let's calculate the area of the triangle

[tex]area = \frac{1}{2} base * height\\area = \frac{1}{2} * 5 * 12\\area = 30m^2[/tex]

But for the length of the missing side, we can simply write it as

[tex]b = 10 + x\\x = (b - 10)m[/tex]

The expressions for the missing sides are;

x = (15- h)mx = (b - 10)m

Answer:

∡ABC=55°

Step-by-step explanation:

Step 1: Identify all angles

∠A=(x+45)°

∠B=(6x+5)°

∠C=(3x)°

∠ABC=(180-∠B)°=(180-(6x+5))°

Step 2: Use the Triangle Angle Sum Theorem

∠A+∠ABC+∠C=180°

(x+45)+(180-(6x+5))+(3x)=180

x+45+180-6x-5+3x=180

-2x+45+180-5=180

-2x+45-5=0

-2x+40=0

-2x=-40

x=20

Step 3: Plug in x=20 for ∠ABC

∠ABC=(180-(6x+5))°

(180-6(20)-5)°

(180-120-5)°

(60-5)°

55°

So ∡ABC=55°

Answer:

∡ABC=55°

Step-by-step explanation:

Step 1: Identify all angles

∠A=(x+45)°

∠B=(6x+5)°

∠C=(3x)°

∠ABC=(180-∠B)°=(180-(6x+5))°

Step 2: Use the Triangle Angle Sum Theorem

∠A+∠ABC+∠C=180°

(x+45)+(180-(6x+5))+(3x)=180

x+45+180-6x-5+3x=180

-2x+45+180-5=180

-2x+45-5=0

-2x+40=0

-2x=-40

x=20

Step 3: Plug in x=20 for ∠ABC

∠ABC=(180-(6x+5))°

(180-6(20)-5)°

(180-120-5)°

(60-5)°

55°

So ∡ABC=55°

A photographer is making an enlargement of a color portrait. If the original portrait is 11 inches by 14 inches and he wants to make the new width 14 inches, about how long should the enlarged length be?

Answers

The width of the original is 11 inches.

The ratio of the width is 14/11

Set up a ratio for the new length:

14/11 = 14/X

Cross multiply:

11x = 196

Divide both sides by 11:

x = 196/11

x = 17.8 inches. (Rounded to the nearest tenth)

Answer:

Original width: 11 inches.

ratio: 14/11

What is the domain when the function is increasing?

What is the domain when the function is constant?

Answers

the first slope going up is when the function increases. when the line goes in a straight line it’s constant. abs when the slope goes down it’s decreasing. so in the photo it first increases, stays constant, decreases, stays constant, decreases

Answer:

at 0 that is when it starts to increase until it hits the 2  on the y- axis. Then there is the constant speed that starts at 1 then ends on 2 on the x-axis. As soon as the constant speed stops it decreases to the number 3 then back at a constant speed to decrease again.

Answer:  2.3 × 0.4 = 0.92 .

2.3 × 1 = 2.3

0.92 + 2.3 = 3.22

Step-by-step explanation:

When decimal points are left out until the end, you can count the number of decimal places to the right of the decimals in the factors and then insert the decimal in the product, counting places right to left.

The factor 2.3 has one decimal place. The factor 0.4 has one decimal place.

Thats a total of 2.

92 becomes .92 when the decimal is inserted two places to the left.

230 becomes 2.30 when the decimal is inserted two places to the left.

Claire can run 20 miles in 95 minutes. How many miles can she run in 285 minutes?

A) 60 miles
B) 6.7 miles
C) 1, 353 miles
D) 190 miles

Answers

Answer:

A

Step-by-step explanation:

20 miles = 95 minutes

X miles = 285 minutes

95/20 = 4.75

285/4.75 = 60

Answer is A (60)

Hope this helps

Answer:

60 miles

Step-by-step explanation:

95 min is the same as 1.583 hours, you use that and do 20/1.583 to get the amount of miles Claire runs per hour. Then you divide 285 by 60 to get how many hours that is, and then you multiply the miles an hour she can run by how many hours 285 minutes is. Hope this helped, it wasn't the best explanation though.
