Answers:

1) -3(x + 8) = -21

2) Division Property of Equality

3) x + 8 = 7

4) Subtraction Property of Equality

Reasoning:

You are already given the equation, so that will be #1 in the Given.

#2 shows both sides being divided by -3, so you will put the Division Property of Equality.

#3 shows the Division Property after it is carried out, so you will put the equation after the division is done.

#4 shows you are subtracting 8 from both sides, so put the Subtraction Property of Equality.

Acute angle:

Acute angle is the angle whose measure angle is less than 90°.

Since ,∠ LHF is 90° and ∠ KHL is within ∠ LHF

∴ ∠ KHL is an Acute angle.

Step-by-step explanation:

Acute angle:

Acute angle is the angle whose measure angle is less than 90°.

Since ,∠ LHF is 90° and ∠ KHL is within ∠ LHF

∴ ∠ KHL is an Acute angle.

Right angle:

The measure of an angle equal to 90° is called a right angle.

∠ LHF is a right angle.

Obtuse angle:

Obtuse angle is the angle whose measure angle is more than 90°.

∠ LHJ is an obtuse angle.

Corresponding angle:

Corresponding angles are formed in parallel lines with a transversal.

In the given figure we do not have any corresponding angles

1 gallon equals 16 cups. So, 3 gallons equal $3\cdot 16 = 48$ cups.

So, 48 cups cost $13.92, which means that one cup costs

$\dfrac{13.92}{48}=0.29$

enyata [817]

Answer:

C. 0.492

Step-by-step explanation:

All I did was add the two numbers. Add them like normal, even though they are in decimal form. You could also use a calculator. If you don't have one, there should be one programed into your phone and computer.

0.467

+ 0.025

= 0.492

Mrs.Scott decides that she would spend no more then $120 to buy a jacket and a shirt. If the price of the jacket was $20 more th

Leona [35]

Highest possible value of shirt = $25

Step-by-step explanation:

DATA:

Total amount to be spent = $120

Price of shirt = x

Price of jacket = 20 + 3x

To find the price of the shirt,

Step 1: Find the value of x

Price of shirt + price of jacket = Total amount to be spent

x + 20 + 3x <= 120

4x + 20 <= 120

4x <= 100

x <= $\frac{100}{4}$

x <= 25

Step 2: Find the value of the shirt by substituting the value of x

Price of shirt = x

Price of shirt = $25

Price of Jacket = 20 + 3x

Price of Jacket = 20 + 3(25)

Price of Jacket = 20 + 75

Price of Jacket = $95

Therefore, the highest possible price of the shirt is $25.
