Answer:
-10
Step-by-step explanation:
7 + 7(-4) - (2(-4)) + 3
7 - 28 - (-8)+3
7 - 28 +8 +3
= -10
That easy just divide 9 by 22 if need simplify it
Answer:
36.67 [mile/hour].
Step-by-step explanation:
1) use the formula: V=S/t, where S - entire jorney, v - average speed (required to calculate), t - elapsed entire time.
2) according to the formula above S=50+60=110 miles; t= 50/40 + 1.75=1.25+1.75=3 hours.
3) after the substitutuion 110 and 3 into the formula above:
v=110/3≈36.67 miles/h.
X^2+ (y+8)^2 = 81.....this is C.
X^2 + y^2 + 16y +64=81 so x^2 + y^2 + 16y = 17.....this is D.
So I’d say C and D are correct

Answer:</h2>
<em>Question 10. </em><u><em>The truck travels faster</em></u><em>.</em>
<em>Question 11. </em><u><em>The slug travels faster</em></u><em>.</em>
<h2>
Step-by-step explanation:</h2>
<h2><u>Question 10.</u></h2>
<u />
<h3>1. Find the velocity of each vehicle.</h3>
<h3>2. Compare the velocities.</h3>
<em>Hence, the trucks travels faster than the car.</em>
<em></em>

<h2><u>Question 11.</u></h2>
<em>Apply the same method as in question 10.</em>
<h3>1. Find the velocity of each body.</h3>
<em />
<h3>2. Compare the velocities.</h3>
Hence, the slug travels faster.
