Answer:

k = 3

Step-by-step explanation:

4 - 7k = 1 - 6k

4 - 1 = - 6k + 7k

3 = k

k = 3

p.s. I changed 3 = k to k = 3 because most math teachers prefer for the answer to be in that order.

Answer:

3 = k

Step-by-step explanation:

Step 1: Write equation

4 - 7k = 1 - 6k

Step 2: Solve for k

Add 7k on both sides: 4 = 1 + k

Subtract 1 on both sides: 3 = k

Answer:

<h2>A. Switch the inequality sign</h2>

When multiplying, you must switch the inequality sign. This is also true when dividing.

EXAMPLE 1:

-4r < -21

r > 5 1/4

Answer:

AC = 7.5 cm

Step-by-step explanation:

Given that the triangles are similar then the ratios of corresponding sides are equal, that is

$\frac{AC}{DE}$ = $\frac{BC}{DE}$ , substitute values

$\frac{AC}{3.5}$ = $\frac{7+8}{7}$ , that is

$\frac{AC}{3.5}$ = $\frac{15}{7}$ ( cross- multiply )

7AC = 52.5 ( divide both sides by 7 )

AC = 7.5 cm
