130% of $20 = $26

How it's done?

130 × 20 ÷ 100 = 26

So, the answer would be 26.

130% changed to a decimal is 1.3. Multiply 1.3 by $20= $26.00

Determine whether the equation represents a direct variation. If it does, find the constant of variation. 2y=5x+1

coldgirl [10]

It does represent a direct variation.

Direct variation: y = kx
y varies directly with x

Your equation 2y = 5x + 1 is in the form of y = kx but we need to divide out the 2 from 2y so we have the following
2y = 5x + 1
2y / 2 = 5 x/ 2 + 1/2
y = 5x / 2 + 1/2
y = kx
k = 5/2
k = constant of variation = 5/2

All of the following are equivalent, except _____.

marusya05 [52]

1. Given (12+3)x, we can sum the numbers in the parenthesis to get 15x

2. Given 12x+3x, we can factor x to get (12+3)x and get the same as 1.

3. Given (12+3x)x, we have to distribute the x and we have $12x+3x^2$

4. This expression is already simplified.

Answer:

$\textsf{(a)} \quad (3x)^{\circ}+(x+14)^{\circ}=90^{\circ}$

$\textsf{(b)} \quad m \angle 1=\boxed{57}\:^{\circ}$

$m \angle 2=\boxed{33}\:^{\circ}$

Step-by-step explanation:

From inspection of the given diagram:

$m \angle 1=(3x)^{\circ}$

$m \angle 2=(x+14)^{\circ}$

<h3><u>Part (a)</u></h3>

A right angle is 90° and is represented by the ∟ symbol.

To find x, <u>equal</u> the sum of the angles to 90° and solve for x:

$\implies m \angle 1+m\angle2=90^{\circ}$

$\implies (3x)^{\circ}+(x+14)^{\circ}=90^{\circ}$

$\implies 3x+x+14=90$

$\implies 4x+14=90$

$\implies 4x+14-14=90-14$

$\implies 4x=76$

$\implies 4x \div 4=76 \div 4$

$\implies x=19$

<h3><u>Part (b)</u></h3>

To find the degree measure of each angle, substitute the found value of x into the expression for each angle.

$\implies m \angle 1=(3 \cdot 19)^{\circ}=57^{\circ}$

$\implies m \angle 2=(19+14)^{\circ}=33^{\circ}$
