Two expressions are below.

G = 2(3x + 10)
H = 6x + 12

Part A:
Apply the distributive property to write an expression that is equivalent to expression G.

Part B:
Explain whether or not expressions G and H are equivalent for any value of x.

Label your answers to both parts of the problem in the response box.

Answers

Answer 1

Answer:

Part A: 6x + 20

Part B: Expression G and H are not equivalent for any value of x.

Step-by-step explanation:

Part A:

G = 2(3x + 10)

G = 6x + 20

Part B:

6x + 20 = 6x + 12

-20 -20

6x = 6x - 8

-6x -6x

0 = -8

No solution. This means that expressions G and H are not equivalent for any value of x.

40°C is equal to 104°F
Step-by-step explanation:
We can find the formula to find the temperature in degrees Fahrenheit with the problem information, the temperature in degrees Fahrenheit is given by:
(1)
F: Temperature in degrees Fahrenheit
C: Temperature in degrees Celsius
Now, with the equation (1) e can find how many degrees Fahrenheit are 40 degrees Celsius.

-9x + 2y = 5
9x − 4y = -19

Answers

hi hruStep-by-step explanation:

-9 + 2y = 5
9x - 4y = -19

Add these equations to eliminate x:
-2y = -14

Then solve -2y = -14 for y:
-2y = -14
-2 -2
(Divide both sides by -2)

y=7

Substitute 7 for y in -9x + 2y = 5:
-9x + (2)(7) = 5
-9x + 14 = 5
-14 -14
(Subtract 14 from both sides)
-9x = -9
-9 -9
(Divide both sides by -9)
x = 1

Tobi can play with his electronics for no more than 2 hours a day. When he wakes up, He plays for 20 minutes. When he comes home from school, he plays for 45 minutes. At most, How many minutes can he play after dinner? Write an inequality and solve.

Answers

He plays 2 hours
20 minutes = when he wakes up
120 - 20 = 100

45 minutes when he comes home
100-45 = 55

Tobi can play 55 minutes after dinner

2 hours is equivalent to 120 minutes so if you do
45+20 = 65 So then you have to subtract 65, the minutes he already spent playing by his total so you do
120-65=55
So he has 55 minutes to play after dinner

The area of the triangle below is 5/12 square feet. What is the length of the base? Express your answer as a fraction in simplest form.

Answers

Answer:

5/3 ft

Step-by-step explanation:

a = (1/2)bh

5/12 = (1/2)(1/2)h

5/12 = 1/4h

Multiply bith sides by 4

20/12 = h

h = 20/12

Reduce

h = 5/3 ft

Answer:

base = 5/3

Step-by-step explanation:

length= x

area triangle =

(bxh)/2

5/12 = x (1/2) divide by 2

Multiply both sides by 1/2 to isolate x

10/12 = 1/2 x

Multiply by 2

20/12 = x

5/3 = x

Solve.

2/3x = 20

How do I create an equation and solve for x

Answers

Answer:

Equation: (2x + 30) + 106 = 180

x = 22°

Step-by-step explanation:

We know that the missing angle from within the triangle and the expression 2x + 30 makes 180 so we can say;

180 - (33 + 41) = missing angle

180 - 74 = missing angle

106° = missing angle

Now we can set up our equation to solve for x:

(2x + 30) + missing angle = 180°

(2x + 30) + 106 = 180° => This would be our equation:

Now let's solve:

2x + 30 + 106 = 180°

2x + 136 = 180

2x = 180 - 136

2x = 44

x = 44/2

x = 22°

Hope this helps!

Answer:

x = 22

Step-by-step explanation:

To solve this the first thing you would need to do is solve the angle that is unmarked in the triangle. To do this you would use the knowledge that the interior agnles of triangles alwasy equal to 180 degrees.

In this case, you would add 33 + 41 = 74 and then you would

subtract 180 - 74 = 106

The next step would be to find the question mark 2x + 30 = ?

To do this you would have to use the 106 degrees from the previous step.

Knowing that (2x + 30) + 106 = 180 degrees this should be easy to solve.

(the angles on either side of a line that is split always add to equal 180 degrees)

You would then subtract 180 - 106 = 74

Now we know that 2x + 30 = 74

Now you would subtract 30 fom both sides to find that 2x = 44

All you have to do now is divide each side by to find that x = 22

14. What is the surface area of this figure in square centimeters?

Answers

Answer:

Step-by-step explanation:

Front and back (triangles

There are two triangles (right angle).

They are found by multiplying the 2 legs together.

Area = 1/2 * b * h

b = 4

h = 3

Area = 1/2 * 4 * 3

Area = 6

But there are 2 of them so the Area = 12

Left face (slanted.

The hypotenuse of the right triangle is 5

a^2 + b^2 = c^2

a = 3

b = 4

c = ?

3^2 + 4^2 = c^2

9 + 16 = c^2

c^2 = 25

sqrt(c^2) = sqrt(25)

c = 5

The front face is 5* 7 = 35

Left side

w = 3

L = 7

Area 3 * 7 = 21

Bottom

L = 7

w = 4

Area = L * W

Area = 7 * 4 28
