2x+8y=9
4x+16y=18
this is because the second equation is the first equation, but multiplied by 2. if one side is multiplied by 2, so is the other
the answer is 18
rounding to nearest 10 to any number follow these rules
1. if number ends 0 , 1 , 2 ,3 4 , 5 take number down to nearset multiple of 10
2. if number ends with above 5 take the upper number multiple of 10
so here
413 + 35.6 + 998.5 + 376 + 85.3
= 410 + 40 + 1000+ 380 + 90
= 1920

2b is basically 2 * b. When a number (called the coefficient) and a variable come together they multiply.
