Question

A. (100-x:75)x35+1=876
B. 5^4:5^2+5x(55^1-x:5)=5^3
Am nevoie urgent!!
Dau 20 de puncte

Answer 1

a. (100-x:75)×35+1=876
(100-x:75)×35=876-1
(100-x:75)×35=875
100-x:75=875:35
100-x:75=25
x:75=100-25
x:75=75
x=75×75
x=5625

b.5^4:5^2+5×(55^1-x:5)=5^3
5^2+5×(55-x:5)=125
25+5×(55-x:5)=125
5×(55-x:5)=125-25
5×(55-x:5)=100
55-x:5=100:5
55-x:5=20
x:5=55-20
x:5=35
x=35×5
x=175

sper ca te-am ajutat !

Answer 2

(100-×:75)×35+1=876
(100-×:75)×35=875
100-×:75=875:35
100-×:75=25
×:75=100-25
×:75=75
×=75×75
×=5625

5 ^4:5^2+5×(55^1-×:5)=5^3
5^2 + 5×(55-×:5)=5^3
25+5×(55-×:5)=125
5×(55-×:5)=125-25
5×(55-×:5)=100
55-×:5=25
×:5=30
×=150
