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
C. H
let me know if i'm wrong-
The correct answer was no need to pay taxes. Not D. Apex confirmed
The length around the rug is the circumference.
The formula is C = 2 x PI x r
C = 2 x 3.14 x 5 = 31.4 feet
The slope =0. Horizontal lines have a slope of 0
