Which is a reasonable first step that can be used to solve the equation 4 x + 3 (x + 2) = 5 (2 x minus 3)? Distribute the 3 to x

+ 2, and distribute the 5 to (2x – 3). Combine 4x and x on the left side of the equation. Apply the subtraction property of equality to move the 2 from the left to the right side of the equation. Apply the addition property of equality to move the 3 from the right to the left side of the equation.

Answer:

Distribute the 3 to x + 2, and distribute the 5 to (2x – 3).

Step-by-step explanation:

Given

$4x + 3(x + 2) = 5(2x - 3)$

Required

Reasonable first step

The reasonable first step is to open the brackets; i.e. distribute 3 to its bracket and 5 to its bracket.

This gives:

$4x + 3(x + 2) = 5(2x - 3)$

$4x + 3x + 6 = 10x - 15$

<em>Then the solution can be continued</em>

Use the diagram below to match the ratios below. B a A b sin B COS B tan B tan A COS A sin A

Paha777 [63]

Answer:

See explanation

Step-by-step explanation:

Given

The attached triangle

Required

Complete the ratios

(a) sin B

$\sin(B)$ is calculated as:

$\sin(B) = \frac{Opposite}{Hypotenuse}$

$\sin(B) = \frac{b}{c}$

(b) cos B

$\cos(B)$ is calculated as:

$\cos(B) = \frac{Adjacent}{Hypotenuse}$

$\cos(B) = \frac{a}{c}$

(c) tan B

$\tan(B)$ is calculated as:

$\tan(B) = \frac{Opposite}{Adjacent}$

$\tan(B) = \frac{b}{a}$

(d) tan A

$\tan(A)$ is calculated as:

$\tan(A)= \frac{Opposite}{Adjacent}$

$\tan(A) = \frac{a}{b}$

(e) cos A

$\cos(A)$ is calculated as:

$\cos(A) = \frac{Adjacent}{Hypotenuse}$

$\cos(A) = \frac{b}{c}$

(f) sin A

$\ain(B)$ is calculated as:

$\sin(B) = \frac{Opposite}{Adjacent}$

$\sin(B) = \frac{a}{c}$
