Answer:

31

Step-by-step explanation:

Recognize that all angles of a triangle add up to 180 degrees, so your equation would be x + 16 + x + 24 + 78 = 180.

Step 1: Combine like-terms.

2x + 118 = 180

Step 2: Subtract 118 from both sides to isolate the variable.

2x = 62

Step 3: Simplify

x = 31

Answer: it is 32.6

Step-by-step explanation:

The orginal number that Gavin was thinking of is 32.60.

Let the orginal number be represented with y

Gavin adds 9 to the original number: 9 + y

The answer is doubled: 2(9 + y)

The answer is 83.2: 2(9+y) = 83.2

In order to determine the value of y, take the following steps:

Divide both sides of the equation by 2

9 + y = 41.60

Subtract 9 from both sides of the equation

y = 41.60 - 9

y = 32.60

Answer:

x = 13

Step-by-step explanation:

Step 1: Define

f(x) = (x - 1)/2

f(x) = 6

Step 2: Substitute and solve for x

6 = (x - 1)/2

12 = x - 1

x = 13

Answer:29° because the angle in between x and 105 is 54(alternate angles) in theory angles on a straight line add upto 180° so therefore x+105+54=180 thus x+159=180 as a result the remaining angle (x) would be 180-159=29° therefore x=29°

Answer:

s=91/8

Step-by-step explanation:

Answer: s=91/8

Step-by-step explanation:

To find the value of s, you want ot use your algebraic properties to isolate s.

4(2s - 1) = 75 + 12                         [distribute by FOIL]

8s-4=75+12                                   [add]

8s-4=87                                         [add both sides by 4]

8s=91                                             [divide both sides by 8]

s=91/8

Answer:

m∠1 = m∠3 = 75°

m∠2 = m∠4 = 105°

Step-by-step explanation:

From the figure attached,

m∠1 + m∠2 = 180° [Supplementary angles]------(1)

Since, m∠2 - m∠1 = 30°

m∠2 = 30° + m∠1 -----(2)

By substituting the value of ∠2 from equation (2) to equation (1),

m∠1 + (m∠1 + 30°) = 180°

2(m∠1) + 30° = 180°

2(m∠1) = 150°

m∠1 = 75°

Therefore, m∠2 = 180°- m∠1 = 180° - 75°

                  m∠2 = 105°

Since, ∠ 2 ≅ ∠4 [Vertical angles]

m∠2 = m∠4 = 105°

Similarly, ∠1 ≅ ∠3 [Vertical angles]

m∠1 = m∠3 = 75°

Answer:

Step-by-step explanation:

the pizza come in slices that are 1/8 each.

there are 36 slices, which means [tex]\frac{36}{288}[/tex].  so the simplest form is 1/8 as well. Maria bought 4 pizzas

The total amount of pizza Maria bought as a fraction is [tex]\frac{36}{4}[/tex] and  8 [tex]\frac{1}{2}[/tex] as a mixed number

Total amount bought = fraction of a slice x total slices bought

[tex]\frac{1}{4}[/tex] x 36  = [tex]\frac{36}{4}[/tex]

The above expression is an improper fraction

An improper fraction is a fraction in which the numerator is greater in value than the denominator

36 is greater than 4

A mixed number is a number that is made up  of a whole a whole number and a proper fraction.

To convert to an improper fraction to a mixed number:

[tex]\frac{36}{4}[/tex] = 8[tex]\frac{2}{4}[/tex]

Answer:

Mean = 81°F.

S. dev. = 5°F.

Step-by-step explanation:

When we have a set of data:

{x₁, x₂, ..., xₙ}

The mean can be calculated as:

M = (x₁ + x₂ ... + xₙ)/N

Where N is the number of data points that we have:

in this case the set is:

{ 74°F , 79°F , 76°F, 85°F, 87°F, 83°F, 86°F, 78°F }

So N = 8.

Then the mean is:

M = ( 74°F + 79°F + 76°F + 85°F + 87°F + 83°F + 86°F + 78°F )/8

M = 81°F.

Now, the standard deviation can be calculated as.

Sd =  √ ( (1/N)*∑(xₐ - M)^2)

where the summation is over xₐ, which represents a summation over all the points in the data set.

Then we can write the standard deviation as:

Sd = √(1/8)*√( (74°F - 81°F)^2 + (79°F - 81°F)^2 + (76°F - 81°F)^2 + (85°F - 81°F)^2 + (87°F - 81°F)^2 + (83°F - 81°F)^2 + (86°F - 81°F)^2 + (78°F - 81°F)^2)

Sd = 4.58°F.

That we should round up to 5°F (because our mean has no digits after the decimal point)

Step-by-step explanation:

The most efficient step to finding the solution to the given inequality is, to subtract 4 from both sides. Option D is correct.

Given that,
To determine which step is the most efficient way to find the solution of x + 4 > -8.

Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.

here,
Given inequality,
x + 4 > -8
Subtract 4 from both sides,
x + 4 - 4 > - 8 - 4
x > -12

Thus, the most efficient step to finding the solution to the given inequality is, to subtract 4 from both sides. Option D is correct.
