Question

Ma poate ajuta cineva cu niste exercitii?
a) ( z -16):5=10
b) (13+z)-40=22
c) (88-z)*2=16
d) (10+z)*5=50
Mulțumesc frumos!!!!

Answer 1

a) (z -16) = 5 * 10
z - 16 = 50
z = 50 + 16
z = 66

b)(13+z) = 40 + 22
13 + z = 66
z = 66 - 13
z = 53

c) (88 - z) = 16 : 2
88 - z = 8
z = 88 - 8
z= 80

d) ( 10 + z) = 50 : 5
10 + z = 10
z = 10-10
z= 0
