Verify a÷(b+c)not equal(a÷b)+a÷c for each of the following values of a, b and c

just olya [345]

Answer:

a) and b) satisfied the condition of the given equation.

Step-by-step explanation:

Given: $\frac{a}{(b + c)}$ ≠ $\frac{a}{b}$ + $\frac{a}{c}$

Then,

$\frac{a}{(b + c)}$ ≠ $\frac{(ac + ab)}{bc}$

a) For a = 21, b = 4 and c = -2, then we have;

$\frac{21}{(4 + (-2))}$ ≠ $\frac{(21*-2 + 21*4)}{4*-2}$

$\frac{21}{4 - 2}$ ≠ $\frac{(-42 + 84)}{-8}$

$\frac{21}{2}$ ≠ $\frac{42}{-8}$

$\frac{21}{2}$ ≠ $-\frac{21}{4}$

Therefore the condition of the given equation is satisfied.

b) For a = 1, b = 10 and c = 1, then we have:

$\frac{1}{(10 + 1)}$ ≠ $\frac{(1*1 + 1*10)}{10*1}$

$\frac{1}{11}$ ≠ $\frac{(1 + 10)}{10}$

$\frac{1}{11}$ ≠ $\frac{11}{10}$

Therefore the condition of the given equation is satisfied.

Your house had a value of $480,000 and increased in value by 3.5%. How much is your house

Phoenix [80]

Answer:

$496800

Step-by-step explanation:

You need to find 3.5% of 480,000 and then add it to 480000:

You convert 3.5% to 0.035 (divided by 100).

Now you multiply 0.035 * $480,000 = $16800 (this is the amount of money to add to the value of the house)

Total value of the house: $480,000 + $16,800 = $496800

What is the equation for y=3x+5

VLD [36.1K]

The graph of y = -3x+5

Step 1: Since the y - intercept is 5, plot the point (0,5).

Step 2: Since the slope is -3, move 1 unit to the right and 3 units down, so plot the point (1,2).

Step 3: Connect those points by a straight line.

Given that two figures are similar, use a scale factor to find the missing length

anastassius [24]

The missing length x is 99 m.

Solution:

Given polygons are similar.

<em>If two triangles are similar, then the corresponding sides are in proportion.</em>

$$\Rightarrow\frac{81}{18}=\frac{x}{22}$

Multiply by 22 on both sides, we get

$$\Rightarrow\frac{81}{18}\times 22=\frac{x}{22}\times 22$

$$\Rightarrow\frac{9}{2}\times 22=x$

⇒ 9 × 11 = x

⇒ 99 = x

Switch the sides.

⇒ x = 99

The missing length x is 99 m.
