Simone wrote that 2+5.8=6.

Use the drop-down menus to explain why 6 is incorrect.



2+5.8 cannot be 6 because 2+5.8 is

Six is a correct sum to the expression +5.8, not 2+5.8.

Slope = -2

Step-by-step explanation:

Answer: The slope is -2

Step-by-step explanation:  Find the difference in y-values divided by the difference in x-values

15 -(-5) = 20

-7 - 3 = -10

20/-10 = -2

                 Statement                               Reason                  

⇒ ∠2 = ∠5 = ∠6 = 3x + 7

Looking at the picture, we can see that ∠6 and 4x + 5 are a linear pair.

Finding the value of x:

⇒ ∠6 + 4x + 5 = 180

⇒ 3x + 7 + 4x + 5 = 180

⇒ 7x + 12 = 180

⇒ 7x = 180 - 12

⇒ 7x = 168

⇒ 7x/7 = 168/7

⇒ x = 168/7 = 24

Now, substitute the value of x into the expression "3x + 7" to find ∠6.

Finding the measure of ∠6:

⇒ ∠6 = 3x + 7

⇒ ∠6 = 3(24) + 7

⇒ ∠6 = 72 + 7

⇒ ∠6 = 79°

Answer:

f^-1(x) = (x+10) / 2

Step-by-step explanation:

sooo

f(x) = 2x - 10

y = 2x - 10

x = 2y - 10

x + 10 = 2y

y = (x + 10) / 2

f^-1(x) = (x+10) / 2

Answer:

[tex]f^{-1}(x)=\frac{x+10}{2}[/tex]

Step-by-step explanation:

[tex]f(x)=2x-10\\\\y=2x-10\\\\x=2y-10\\\\x+10=2y\\\\\frac{x+10}{2}=y\\ \\f^{-1}(x)=\frac{x+10}{2}[/tex]

As the two functions are inverses of each other, they will be symmetrical about the line [tex]y=x[/tex].

the original probability is 7/6 favoring odd

Answer:

x = 129.8 degrees,  y = 50.2 degrees,    x + y = 180

Step-by-step explanation:

Let's say you have 2 supplementary angles, x and y

So x + y = 180

if x is 79.8 degrees less than the measure of a supplementary angle, then x = y - 79.8

Putting this into our x + y = 180 equation, we get

(y - 79.8) + y = 180

2y - 79.8 = 180

2y = 180 + 79.8

2y = 259.8

y = 259.8/2 = 129.9 degrees.

so x = 129.9 - 79.6 = 50.3 degrees.

See if it worked. x = 129.9 degrees,  y = 50.3 degrees,    x + y = 180 so we found the correct two angles! :-)

Answer:

Let the first number be f.

Let the second number be s.

f = s-12

f+s = 100

Substitute the f in the first equation for the second equation.

s-12+s = 100

2s-12 =100

2s = 112

s = 56

Therefore f = 56-12 = 44

The 2 numbers are 56 and 44.

Answer:

m∠2 is 55°

Step-by-step explanation:

Let us revise some facts in geometry

We will use these facts to solve our question

∵ ∠1 is an angle of a triangle

∴ m∠1 + 40° + 85° = 180° ⇒ 1st fact

→ Add the like terms in the left side

∴ m∠1 + 125° = 180°

→ Subtract 125° from both sides

∴ m∠1 + 125° - 125° = 180° - 125°

∴ m∠1 = 55°

∵ ∠1 and ∠2 formed from the intersecting of two lines

∴ ∠1 and ∠2 are vertically opposite angles

∴ m∠1 = m∠2 ⇒ 2nd fact

∵ m∠1 = 55°

∴ m∠2 = 55°

The expression which represents the total number of miles he jogs in a week is 7 m ⇒ A

Step-by-step explanation:

Let us solve the question

∵ Dominic goes jogging every morning

∵ m represents the number of miles he jogs each day

→ That means he jogs m miles every day

∵ There are 7 days in a week

→ That means he jogs m miles every day for 7 days

∵ m + m + m + m + m + m + m = 7 × m

∴ He jogs in 1 week 7 × m miles

∴ He jogs 7 m miles in a week

The expression which represents the total number of miles he jogs in a week is 7 m

Answer:

A. 7m

========================================================

The card says we need 1 & 1/2 cups of flour

Let's convert this to decimal form

1 & 1/2 = 1 + 1/2

1 & 1/2 = 1 + 0.5

1 & 1/2 = 1.5

The mixed number 1 & 1/2 is equivalent to the decimal number 1.5

Now multiply this by 3. This is because the recipe originally serves 10 people, but we want to serve 3 times as many people (3*10 = 30 total).

So,  3*1.5 = 4.5

Now convert back to a mixed number

4.5 = 4 + 0.5

4.5 = 4 + 1/2

4.5 = 4 & 1/2

We'll need 4 & 1/2 cups of flour.

----------------------

Here's another way to approach the problem

Multiply 3 by 1 & 1/2 to get

3*(1 & 1/2) = 3*(1 + 1/2)

3*(1 & 1/2) = 3*1 + 3*1/2

3*(1 & 1/2) = 3 + 3/2

3*(1 & 1/2) = 3 + (2+1)/2

3*(1 & 1/2) = 3 + 2/2 + 1/2

3*(1 & 1/2) = 3+1 + 1/2

3*(1 & 1/2) = 4 + 1/2

3*(1 & 1/2) = 4 & 1/2

Answer:

16 cm

Step-by-step explanation:

Area of triangle= ½ ×base ×height

Substitute given information into the formula:

96= ½ ×base ×12

Simplify:

96= 6 ×base

Divide both sides by 6:

base= 96 ÷6

base= 16 cm

Answer:

[tex] \\ [/tex]

Step-by-step explanation:

It is given that, the height of a triangle is 12cm, and its area is 96cm² and we have to find the base of triangle.

[tex] \\ [/tex]

To find the base of the triangle, we have to know this formula :

[tex] \\ {\longrightarrow \pmb{\frak {\qquad \frac{1}{2} \times Base \times Height = Area_{(Triangle)} \:}}} \\ \\[/tex]

Now, substituting the values in the formula :

[tex]{\longrightarrow \pmb{\sf {\qquad \frac{1}{2} \times Base \times 12 = 96 \:}}} \\ \\[/tex]

[tex]{\longrightarrow \pmb{\sf {\qquad \frac{1}{ \cancel2} \times Base \times \cancel{12 } = 96 \:}}} \\ \\[/tex]

[tex]{\longrightarrow \pmb{\sf {\qquad {1} \times Base \times 6 = 96 \:}}} \\ \\[/tex]

[tex]{\longrightarrow \pmb{\sf {\qquad Base \times 6 = 96 \:}}} \\ \\[/tex]

[tex]{\longrightarrow \pmb{\sf {\qquad Base = \frac{96}{6} \:}}} \\ \\[/tex]

[tex]{\longrightarrow \pmb{\frak {\qquad Base = 16\:}}} \\ \\[/tex]
