Answer:
47
Step-by-step explanation:
x-5=42
x=42+5
x=47
Answer:
x = 4.5 or rounded 5
Step-by-step explanation:
Because they are equal you can make the equation:
x/2 = 18/8
this means that 8 divided by 2 equals (4)
what 18 divided by x is (4)
this means 4 times x = 18
4x = 18
/4 /4
x = 4.5 ft
3x+7<19
3x+7-7<19-7
3x<12
3x/3<12/3
x<4.
