The answer will be 9 miles her is my example of course I made my example the harder way but you could do it easier which is just to divide. Anyways here's my exampleI hope it helped
Answer: i think its true
Step-by-step explanation:
Isolate the a. Note the equal sign. What you do to one side, you do to the other.
Add 5 to both sides
-5 (+5) + 1/5a = 4 (+5)
1/5a = 9
Isolate the a. Multiply 5 to both sides
(5)(1/5)a = 9(5)
a = 9 x 5
a = 45
45 is your answer for a.

Given data in that table forms the 2x3 matrix shown below 2 7 6 5 4 5 a 3-point field goal is worth 3 points a normal field goal is worth 2 points a free throw is worth 1 points.
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
