Answer: QS=68 units
Step-by-step explanation:
<em>RT=RS+ST</em>
<em>8x-43=2x-4+4x-1</em>
<em>8x-43=6x-5</em>
<em>8x-43-6x=6x-5-6x</em>
<em>2x-43=-5</em>
<em>2x-43+43=-5+43</em>
<em>2x=38</em>
<em>Divide both parts of the equation by 2:</em>
<em>x=19</em>
<em>QS=RS+RQ</em>
<em>As, RS=RQ</em>
<em>QS=2RS</em>
<em>QS=(2)((2)(19)-4))</em>
<em>QS=(2)(38-4)</em>
<em>QS=(2)(34)</em>
<em>QS=68</em>
Answer:
k = 7
Step-by-step explanation:
given y varies jointly with x and w then the equation relating them is
y = kxw ← k is the constant of variation
to find k use the condition when y = - 42, x = 2 and w = - 3 , then
- 42 = k × 2 × - 3
- 42 = - 6k ( divide both sides by - 6 )
7 = k
constant of variation is k = 7
Answer:
Distance is 10
Step-by-step explanation:
distance between y1=2x-3 and y2= 2x+7
y2 - y1 = (2x +7) - (2x - 3) = 10
The X (1) axis represents the number of hours, and the Y (75) axis represents the number of dollars. When 0 hours are passed, 0 hours are payed (0,0) 1 hour 75 dollars are payed (1, 75) 2 hours 150 dollars is payed (2, 150) and so on
Answer:
The answer is 79 degrees
Step-by-step explanation:
Vertically opposite angles are exactly the same. In this case M<AED and M<IEF are vertically opposite from each other.
