14x-56y-42
Given data
We have the expression
7(2x - 8y - 6)
Open the bracket we have
Hence the equivalent expression is
Answer: 165 minutes (2.75 hours)
The two numbers are 17 and 7.
x+y=24
x-y=10
------------
2x=34
x=34/2
x=17
17-y=10
y=17-10
y=7
First do 6+7 (PEMDAS), plus 2 and then plus 54
2+(-11) is -9
The answer is 98 square cm
14/2=7
14*7=98
