Answers

Answer:

110

Step-by-step explanation:

3x+5+2x=180

Step 1: Simplify both sides of the equation.

3x+5+2x=180

(3x+2x)+(5)=180(Combine Like Terms)

5x+5=180

Step 2: Subtract 5 from both sides.

5x+5−5=180−5

5x=175

Step 3: Divide both sides by 5.

x=35

35*3+5=110

. In a 30°-60°-90° triangle, the length of the hypotenuse is 12 inches. What is the length, in inches, of the side opposite the 60° angle?

Answers

The sides of a 30-60-90 triangle are always in the ratio 1:√3:2, respectively.

The side opposite the 90° is 12 inches, so the side opposite the 30° angle is 6 inches, and the side opposite the 60° angle is 6√3 inches.

Lin lines the bottom of her first pan with aluminum foil. The area of the rectangular piece of foil is 11 1/4 square inches. Its length is 4 1/2 inches. What is the width of the foil?

Answers

Answer: the answer is 2.5

Step-by-step explanation:

Answer:

w= 5/2 inches or 2 1/2 inches

Step-by-step explanation:

area = length × width (w)

45/4 = 9/2 × w

45/4 =9w/2

45×2 = 9w×4

90 = 9w×4

9w= 90/4= 45/2

w= 45/2 × 1/9

w= 5/2 inches or 2 1/2 inches

Dakota has 4/10 kg of clay he divided the clay to make eight equal parts how many grams of clay are in each pot

Answers

Answer:

Dakota must put 50 grams of clay in each pot to be able to divide the clay into 8 equal parts.

Step-by-step explanation:

Given that Dakota has 4/10 kg of clay and I divided the clay to make eight equal pots, to determine how many grams of clay are in each pot the following calculation must be performed:

4/10 kg = 0.4 kg = 400 grams

400/8 = X

50 = X

Thus, Dakota must put 50 grams of clay in each pot to be able to divide the clay into 8 equal parts.
