<span>10(6-5)-3(9-6) = 10 x 1 - 3 x 3 = 10 - 9 = 1</span>
Only one, if you want to know the measurement of the other side use the cosine law and to know the other angles use the sine law :)
Answer:
p =
and q = 
Step-by-step explanation:
Given equations:
2p - 3q = 4 -----------(i)
3p + 2q = 9 ------------(ii)
Let's solve this equation simultaneously using the <em>elimination method</em>
(a) Multiply equation (i) by 3 and equation (ii) by 2 as follows;
[2p - 3q = 4] x 3
[3p + 2q = 9] x 2
6p - 9q = 12 -------------(iii)
6p + 4q = 18 -------------(iv)
(b) Next, subtract equation (iv) from equation (iii) as follows;
[6p - 9q = 12]
<u> - [6p + 4q = 18] </u>
<u> -13q = -6 </u> -----------------(v)
<u />
<u>(c)</u> Next, make q subject of the formula in equation (v)
q = 
(d) Now substitute the value of q =
into equation (i) as follows;
2p - 3(
) = 4
(e) Now, solve for p in d above
<em>Multiply through by 13;</em>
26p - 18 = 52
<em>Collect like terms</em>
26p = 52 + 18
26p = 70
<em>Divide both sides by 2</em>
13p = 35
p = 
Therefore, p =
and q = 
Answer:
0.9 hours

the nature of line is pure liner
Step-by-step explanation:
The attached graph is the drawn graph of given data
i) A teenager would spend exercising in one day if they spent 0.25 hours on social media.
0.9 hours
According to the graph if you locate the 0.25 hour on x-axis and draw perpendicular the will intersect the line on the value of y-axis is = 0.9 hours
ii) if they spent 1.38 hours on social media the corresponding value of exercising per day is approx 0
iii) Yes it has the best fit value of corresponding values between two. which is also reasonable in the all cases. the nature of line is pure liner.
