Question

12. Evalúa cada expresión algebraica si t = 6, x = 3, y = 4, z = 5:
a. 2(x + 7)
b. 5y-3
c. (18-4)x
d. 7z+8
e. Z(t-y)
f. 4 (xz + 3y)​

Answer 1

Explicación paso a paso:

$t = 6; \: x = 3; \: y = 4; \: z = 5$

a) 2(x + 7)

$2(3 + 7) = 2(10) = 20$

b) 5y - 3

$5(4) - 3 = 20 - 3 = 17$

c) (18 - 4)x

$(18 - 4)(3) = (14)(3) = 42$

D) 7z + 8

$7(5) + 8 = 35 + 8 = 43$

e) Z( t - y)

$5(6 - 4) = 5(2) = 10$

f) 4(xz + 3y)

$4(3(5) + 3(4)) = 4(15 + 12) = 4(27) \\ = 108 \:$
