Question

a)x : (-8) = -20 b)y : 38 = 10 c)z : (-19) = -18



d)3x + 72 =0 e)-8y + 800 = 0 f)22z + 440 = 0

Va rog!!!

Answer 1

A)
x : (-8) = -20
x = -20 * (-8)
x = 160

B)
y : 38 = 10
y = 10 * 38
y = 380

C)
z : (-19) = -18
z = -18 * (-19)
z = 342

D)
3x+72 = 0
3x = -72
x = -72 : 3
x = 24

E)
-8y + 800 - 0
-8y = -800
y = -800 : (-8)
y = 100

f)
22z + 440 = 0
22z = -440
z = -440 : 22
z = -20

Answer 2

a)x : (-8)=-20
-(x)/(8)
-x=-160
