Mathematics

Hoochie [10]3 years ago

(x + 6)/2 - (x - 8)/3 = 5
Multiply each term by 6:-
3(x + 6) - 2(x - 8) = 30
3x + 18 - 2x + 16 = 30
3x - 2x = 30 -18 - 16
x = 30 - 34
x = -4 (answer)

I assume you meant x + 6 as a numerator and x - 8 as a numerator although that is not what the equation you wrote means.

\dfrac{x + 6}{2} - \dfrac{x - 8}{3} = 5

\dfrac{x + 6}{2} \times \dfrac{3}{3} - \dfrac{x - 8}{3} \times \dfrac{2}{2} = 5

\dfrac{3(x + 6)}{6} - \dfrac{2(x - 8)}{6} = 5

\dfrac{3x + 18}{6} - \dfrac{2x - 16}{6} = 5

\dfrac{3x + 18 - 2x + 16}{6} = 5

\dfrac{x + 34}{6} = 5

\dfrac{x + 34}{6} \times 6 = 5 \times 6

x + 34 = 30

x = -4

A clothing store pays $89.47 for a dress. The store’s percent of markup is 50% and the tax is 7.6%. Find the selling price for t
Goryan [66]
Hi,
<span>SP=Selling Price
</span>CP of dress= $ 89.47
percent of mark up = 50%
SP without tax= 100+ mark up % /100 * CP
<span>SP without tax= 100+50/100 * 89.47
</span>SP without tax= 150/100 * 89.47
SP without tax= 1.5 * 89.47
<span>SP without tax= $ 134.205
</span>tot. SP(SP with tax)= 100 + tax %/100 * SP
<span>SP=100 + 7.6/100 * 134.205
</span>SP= 107.6/100 * 134.205
SP= 1.076 * 134.205
<span>SP=  $144.40458
Hope this helps you.</span>

The area of a sector of a circle with a radius measuring 15 cm is 75(pi) cm2. What is the measure of the central angle that form
anyanavicka [17]

The sector of the circle is bounded by 2 radii, and the measure of the central angle that forms the sector is 120 degrees

<h3>How to determine the central angle?</h3>

The given parameters are:

  • Area = 75π cm^2
  • Radius, r = 15 cm

The area is calculated using

Area = α/360 * πr^2

So, we have:

α/360 * π * 15^2 = 75π

Evaluate the exponent

α/360 * π * 225 = 75π

Divide both sides by 75π

α/360 * 3 = 1

Multiply

α/120  = 1

Multiply both sides by 120

α = 120

Hence, the measure of the central angle that forms the sector is 120 degrees

A triangle has two sides of lengths 6 and 9. What value could the length of the third side be?
Diano4ka-milaya [45]

The sum of the lengths of two sides of a triangle must always be less than or equal to the third side. So, if we let the third side be x, we have:

\begin{cases}6+x\geq9\\x+9\geq6\\6+9\geq x\end{cases} \iff \begin{cases}x\geq3\\x\geq -3\\x\leq 15\end{cases} \iff \begin{cases}x\geq3\\x\leq 15\end{cases}

What is the missing value in x2y8 · x3y? = x5y5?
sweet-ann [11.9K]

Answer:

-3

Step-by-step explanation:

To find:

The value of '?' in the following expression:

x^2y^8.x^3y^? = x^5y^5

Solution:

First of all, let us have a look at a few rules of the exponents:

1.\ a^b.a^c=a^{b+c}

2.\ a^b.a^{-c}=a^{b-c}

Let us apply these rules and try to find out the missing value ('?') in the given expression.

Left Hand Side (LHS):

x^2y^8.x^3y^?\\\Rightarrow x^2.x^3.y^8.y^?\\\Rightarrow x^{2+3}y^{8+?}\\\Rightarrow x^{5}y^{8+?}

Now, let us compare the LHS with RHS, we get:

x^{5}y^{8+?} = x^{5}y^{5}

Dividing with x^5 on both sides:

y^{8+?} = y^5\\\Rightarrow 8+? = 5\\\Rightarrow ? = 5-8 \\\Rightarrow ? =-3

Therefore, the missing value in the expression is <em>-3.</em>
