Answer:

x=21

Step-by-step explanation:

We know that the angles of a triangle has a sum of 180 degrees always. We know two sides already which are 45 and 63. Their sum is 108 degrees which means that the missing side is 180-108 which is 72.

Now we can set 72 equal to 4x-12 since the last side has to equal 72 and solve.

72=4x-12

84=4x

x=21

Answer: 24/5=4.8  36/8=4.5

Step-by-step explanation: First, let's start off by dividing 24 by 5. We can turn this into 24.0 divided by 5 to make it a bit simpler. We know that 240 by 5 = 48, then since there is a decimal 1 digit to the left in 24.0, we apply that decimal 1 digit to the left in 48, making it 4.8! Now let's do 36 by 8. We can do what we did for problem 1 and turn 36 into 36.0, 360 by 8 = 45 and applying the same logic we used before, 360 turns into 36.0, and 45 turns into 4.5! Therefore, Kalel is wrong, and the two equation is not equal.

P.S. Using long division, Kalel is technically kind of right, but there's still that unaccounted for '4' that we still need to divide.

Answer:

Multiply both sides of the equation by n/-2.25

Step-by-step explanation:

[tex]\frac{n}{-225}=15.6[/tex]

[tex]\mathrm{Multiply\:both\:sides\:by\:}-2.25[/tex]

[tex]\frac{n\left(-2.25\right)}{-2.25}=15.6\left(-2.25\right)[/tex]

[tex]\mathrm{Simplify}[/tex]

[tex]n=-35.1[/tex]

~lenvy~

Answer:

Step-by-step explanation:

To solve this problem, first, you have to isolate the term of n from one side of the equation.

[tex]\sf{\dfrac{n}{-2.25}=15.6 }[/tex]

The only way to solve this is to multiply both sides by -2.25.

[tex]\sf{\dfrac{n(-2.25)}{-2.25}=15.6(-2.25) }[/tex]

After that, you solve.

Multiply the numbers from left to right.

[tex]\sf{15.6(-2.25)=\boxed{\sf{-35.1}}[/tex]

The total amount accrued, principal plus interest, with compound interest on a principal of $1,000.00 at a rate of 3% per year compounded 12 times per year over 0.5 years is $1,015.09.

Given Data

First, convert R as a percent to r as a decimal

r = R/100

r = 3/100

r = 0.03 rate per year,

Then solve the equation for A

A = P(1 + r/n)^nt

A = 1,000.00(1 + 0.03/12)^(12)(0.5)

A = 1,000.00(1 + 0.0025)^(6)

A = $1,015.09

Answer:

y = 3x - 2

Step-by-step explanation:

Use the point-slope equation since we are given a point that the line passes through and its slope:

y - y1 = m(x - x1)

(-2, -8), m = 3

Substitute these values into the equation.

The equation of the line that passes through the point (-2, -8) and has a slope of 3 is y = 3x - 2.

Answer:

About 28.27 inches² per slice

Step-by-step explanation:

   First, we will find the area of the pizza. Since it is a pizza, we will assume it is a circle and will use the formula for area of a circle.

   24-inch diameter / 2 = 12-inch radius

   A=πr²

   A=π(12)²

   A ≈ 452.39 inches²

   Now, since the pizza is cut into 16 slices, we will divide the total area by 16.

452.39 inches² / 16 ≈ 28.27 inches² per slice

Answer:

215.625 square feet.

Step-by-step explanation:

The best way to approach this is by finding the area of each shape and then adding them together.

The area of a rectangle is Length · Width. Both rectangles have a length of 12.5 feet and a width of 7.5 feet. 12.5 · 7.5 = 93.75. And since both rectangles have the same dimensions, we can just multiply 93.75 by two to get 187.5 square feet for the rectangles.

The area of a triangle is Base · Height / 2. Since the sides of the triangle are the same as the sides of rectangles, the dimensions of the triangle are 7.5 feet and 7.5 feet.

7.5 · 7.5 / 2 = 28.125 square feet.

187.5 + 28.125 = 215.625 square feet.

Answer:

[tex]\boxed{a = 6.4}[/tex]

Step-by-step explanation:

Given:

[tex]x:y = (4):(5)[/tex]

Let the value of "x" be known as "a".

[tex]x:y = a:8[/tex]

Setting up the proportion:

[tex]\rightarrow 4:5 = a :8[/tex]

Multiplying the middles and the extremes:

[tex]\rightarrow 5a = 4 \times 8[/tex]

Simplifying the RHS:

[tex]\rightarrow a = \dfrac{4 \times 8}{5}[/tex]

[tex]\rightarrow \boxed{a = 6.4}[/tex]

Thus, the value of x is 6.4 when y is 8.

Answer:

[tex]\sf x=\dfrac{32}{5}[/tex]

(or x = 6.4 if you want it in decimal form)

Step-by-step explanation:

If y and x have a proportional relationship, then:

Given:

Substitute the given values into the equation to find k:

⇒ 5 = k(4)

⇒ k = 5/4

Therefore, [tex]\sf y=\dfrac54x[/tex]

When y = 8, substitute y = 8 into the equation and solve for x:

[tex]\sf \implies \dfrac54x=8[/tex]

[tex]\sf \implies x=8 \cdot \dfrac45[/tex]

[tex]\sf \implies x=\dfrac{32}{5}[/tex]
