Find the surface area of the triangular prism

Answers

Answer:

169 cm^2

Step-by-step explanation:

Right surface (rectangle)

A = LW = 7 cm * 5 cm = 35 cm^2

Left surface (hidden rectangle)

A = LW = 7 cm * 5 cm = 35 cm^2

Bottom surface (hidden rectangle)

A = LW = 9 cm * 5 cm = 45 cm^2

Front face = back face = 2 * triangle

A = 2 * bh/2 = 2 * 9 cm * 6 cm/2 = 54 cm^2

total surface area = 35 cm^2 + 35 cm^2 + 45 cm^2 + 54 cm^2 = 169 cm^2

Carina begins to solve the equation Negative 4 minus two-thirds x equals negative 6 by adding 4 to both sides. Which statements regarding the rest of the solving process could be true? Select three options. After adding 4 to both sides, the equation is Negative two-thirds x equals negative 2. After adding 4 to both sides, the equation is Negative two-thirds x equals negative 10. The equation can be solved for using exactly one more step by multiplying both sides by Negative three-halves. The equation can be solved for x using exactly one more step by dividing both sides by Negative two-thirds. The equation can be solved for x using exactly one more step by multiplying both sides by Negative two-thirds.

Answers

Answer:

options 3 and 4 are correct

Step-by-step explanation:

And form the remainder of the problem, you isolate x by just multiplying by the negative reciprocal, which is -3/2, or just dividing by the number in front off x, which is -2/3, which makes statements three and four true. so this makes this three and four options

What is a linear equation?

A linear equation is an algebraic equation where each term has an exponent of 1 and when this equation is graphed, it always results in a straight line. This is the reason why it is named as a 'linear equation'.

Given here  -4-2/3x +4=-6+4

                 ⇒-2/3x = -2

                 ⇒ -2/3x ×3/2 = -2 ×3/2

                 ⇒ x = 3

Hence the final answer is 3.

9x-6y=-20 through (0,-4)

Answers

To make the equation go through (0,-4) the new equation would be 9x + 5y = 20. We needed to change it from subtracting to adding so the direction of the line would go from going down to up too up to down. In slope-intercept form the original equation would be found by the following.

9x - 6y = 20

-6y = 20 - 9x

y = -20/6 - (-9/6x)

y = 9/6x - 20/6

y = 3/2x - 10/3

To make the perpendicular line, take the slope and apply the opposite and reciprocal.

y = -2/3x - 10/3

You have $55 in your bank account, and you would like to buy a new phone for $395. You can save $5 for each hour you work. How many hours must you work to buy it?

Answers

Answer:

(At least) 68 hours

Step-by-step explanation:

So we already have $55 in our bank account.

And we earn $5 per hour.

In other words, the total amount of money in our account after working x hours is represented by the equation:

[tex]y=5x+55[/tex]

We want to buy a new phone that costs $395. To find out how many hours we need to work, substitute 395 for y. Thus:

[tex]395=5x+55[/tex]

Subtract 55 from both sides:

[tex]340=5x[/tex]

Divide both sides by 5:

[tex]x=68[/tex]

Therefore, we must work for (at least) another 68 hours in order to earn enough money to purchase the phone.

3.5 + 1.2(6.3-7x) =9.38

Answers

Answer:

x = 0.2

Step-by-step explanation:

Order of Operations: BPEMDAS

Step 1: Write out equation

3.5 + 1.2(6.3 - 7x) = 9.38

Step 2: Parenthesis (distribute)

3.5 + 7.56 - 8.4x = 9.38

Step 3: Combine like terms (constants)

11.06 - 8.4x = 9.38

Step 4: Subtract 11.06 on both sides

-8.4x = -1.68

Step 5: Divide both sides by -8.4

x = 0.2

evaluate the expression for the given value of the variable 9 | 9 -8x | = 2x + 3

Answers

Steps to solve:

9|9 - 8x| = 2x + 3

~Divide 9 to both sides

|9 - 8x| = 2/9x + 1/3

~Solve absolute value (part one)

|9 - 8x| = 2/9x + 1/3

-74/9x + 9 = 1/3 (Subtracted 2/9x to both sides)

-74/9x = -26/3 (Subtracted 9 to both sides)

x = 39/37 (Multiplied 37/39 to both sides)

~Solve absolute value (part two)

|9 - 8x| = -(2/9x + 1/3)

|9 - 8x| = -2/9x - 1/3 (Distributed negative sign to left side)

-70/9x + 9 = 11/3 (Added 2/9x to both sides)

-70/9x = -28/3 (Subtracted 9 to both sides)

x = 6/5 (Multiplied 9/-70 to both sides)

Therefore, the solutions are x = 39/37 and x = 6/5
