Answer:
5 x 8 /a*7
Step-by-step explanation:
Answer:9
Step-by-step explanation: x+4=13
x=13-4
x=9
4.5{4_x}+36=202-2.5{3+28}
you first multiply 4.5 and the numbers in the bracket.
4.5*4=18
4.5*x=4.5x
you will obtain 18-4.5x=202_2.5{3+28}
2.5*3=7.5 2.5*28=70
18_4.5x=202_7.5_70
18_4.5x=124.5_18
-4.5x=106.5
x=23.67
Answer is 360,,,,,,,,,........
