List all the elements of each set. Set of the values of x that turn equation 0.7(x−7)−4.9=5.7 into a true statement

22.14 (22.1428571429)

Step-by-step explanation:

OK

Let's Start with the equation

0.7(x−7)−4.9=5.7

Add 4.9 to both sides

0.7(x-7)=10.6

Divide both sides by 0.7

x-7= 15. 1428571429

Add 7 to both sides

x= 22.1428571429 or 22.14

the cost of the pair of pants is $31.95

part a: triangles gcb and epb

part b. sides cg and rp are parallel by definition of parallelogram.

angles cgb and e are congruent by being alternate interior angles of parallel lines cut by a transversal. angles gbc and ebp are congruent because they are vertical angles. by aa similarity, the triangles are similar.

part c. since the triangles are similar, the ratios of the lengths of corresponding sides are equal.

calculation of be:

gb/be = cb/bp

(400 ft)/be = 300/200

(400 ft)/be = 3/2

3be = 2 * 400 ft

3be = 800 ft

be = 800/3 ft

calculation of pe:

gc/pe = cb/bp

(350 ft)/pe = 300/200

(350 ft)/pe = 3/2

3pe = 2 * 350 ft

3pe = 700 ft

pe = 700/3 ft
