Step-by-step explanation:
2100 calories
We find this by multiplying 600 times 3.5
An easy way to do this is multiplying 600 times 3 (1800) and the adding half of 600 (300) to your number for the final number of 2100 calories.
Lets write an equation for each guy's shots and score:
4A + 2B = 18
3A + 3B = 21
To solve we multiply the first equation by -3 and the second by 2:
-12A - 6B = -54
6A + 6B = 42
--------------------
-12A + 0 = -12
A = 1
to find B we substitute in the first equation:
<span>4A + 2B = 18
</span><span>4(1) + 2B = 18
</span><span>4 + 2B = 18
</span>2B = 14
B = 7
therefore there were given 7 points in an arrow in B
