Pentagon PQRST ~ pentagon XYZVW. find the value of b. will give brainlist

prohojiy [21]

Answer:

Step-by-step explanation:

(4a - 3)/(3b + 1) = 39/(a + 1) You are not going to get a numerical answer for this. Cross multiply

(4a - 3)(a + 1) = 39(3b + 1)

4a^2 + a - 3 = 117b + 39

4a^2 + a - 42 = 117b

b = $\frac{a^2 +a - 42}{117}$

Fill in the missing reasons (one for each step). Given: 3x – 6y = 27; x = 5 Prove: -2 = y

JulsSmile [24]

Answer:

a. Given,

b. Substitution

c. Subtraction of equality

d. Division of equality

e. Symmetric property of equality

Step-by-step explanation:

Given expression,

$3x - 6y = 27; x = 5$

By substituting x = 5,

$3(5) - 6y = 27$

$15 - 6y = 27$

By subtraction property of equality,

$-6y = 12$

Division property of equality,

$y = -2$

By symmetric property of equality,

$-2 = y$
