Answer:
x= (y-5)/2
Step-by-step explanation:
Isolate the x variable.
y= 2x +5
Subtract 5 from both sides.
y-5=2x
Divide both sides by 2.
(y-5)/2= x
Answer:
852
6×10(6)+7×10(5)+3×10(2)+8×10+2= 852
Step-by-step explanation:
ORDER OF OPERATIONS Will really help you solve this long problem.
Order of operations is PEMDAS.
P-parenthesis
E-exponents
M-multiplication
D-division
A-addition
S-subtraction
6)(10)(6)+(7)(10)(5)+(3)(10)(2)+(8)(10)+2
=(60)(6)+(7)(10)(5)+(3)(10)(2)+(8)(10)+2
=360+(7)(10)(5)+(3)(10)(2)+(8)(10)+2
=360+(70)(5)+(3)(10)(2)+(8)(10)+2
=360+350+(3)(10)(2)+(8)(10)+2
=710+(3)(10)(2)+(8)(10)+2
=710+(30)(2)+(8)(10)+2
=710+60+(8)(10)+2
=770+(8)(10)+2
=770+80+2
=850+2
=852
