Step-by-step explanation:

so A = 64a +45
(
so B = 108 +a
2A-B=0--> 2(64a+45)-108-a=0--> a =18/127
<span>seven hundred and seventy thousand and seventy is the word form of 770,070</span>
Their are 16 logs the stove burn in 8hours
3x + y = -3
-2x + y = 7
Use elimination method
Subtract both equations
5x = -10, x = -2
Plug in -2 for x (any equation)
3(-2) + y = -3
-6 + y = -3
y = 3
Solution: x = -2, y = 3
Or as a coordinate: (-2, 3)
7 yrds/sec because in the course of two seconds, he runs 14 yrds divide that by 2 to get 7 yrds/sec. you can allo chech with the next time which is 3 seconds more and he goes 21 yards more.
