6.     the two rectangles in the figure are similar. what is the value of  x?  
            a.  29.4    b.  15    c.  6.7

B. 15

Step-by-step explanation:

We can write a proportion to solve

14         10

=

21          x

Using cross products

14x = 21*10

14x =210

Divide each side by 14

14x/14 = 210/14

x =15

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
