(1) t+w=15 ==> t=15-w
(2) 2*t ==>2*(15-w)=40-2w
(2) 30-2w=40-2w
==> 0w=10
so that there is no solution which means inconsistent.
Answer:
a)
b)
c)
Explanation -
a) 2/3 p + 10 = r
Value of r = 22 (given)
2/3 p + 10 = 22
2/3 p = 22- 10
2/3 p = 12
p = 12 × 3 /2
p = 6 × 3
<em><u>p</u></em><em><u>=</u></em><em><u>1</u></em><em><u>8</u></em><em><u> </u></em>
b) (-17) + 5k = t
value of k = 4 (given)
(-17) +5 (4) = t
(-17) + 20 = t
<em><u>3</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>t</u></em><em><u> </u></em>
c) 0 = 5p - 3b
b= 2 (given)
0 = 5p - 3(2)
0 = 5p - 6
6 = 5p
<em><u>6</u></em><em><u>/</u></em><em><u>5</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>p</u></em>
The slope would be y = -1/2x + 3
The y intercept is where the line crosses the y axis which is at 3 and the slope is rise over run -2/4 or -1/2
M<2 = 90 - 64 = 26
answer
26
