Answer:
43
Step-by-step explanation:
v+47 is equal to 90 degrees, because it's a right angle
v+47=90
to get 90 in this equation, v must equal 43.
that means v=43
The variable y is given.
now, substitute y in the second equation to get
-4x - (-4x-7) = 7
then we solve
first distribute
-4x+4x+7=7
combine like terms
0+7 = 7
7 = 7
because the answer is true, the solution to this system is “all real numbers”
The answer for that is -2.
<span>The
problem said that for each part, there is 1/10 mile long. If Marsha finished 5
parts of the race, just multiply 5 by 1/10 and you will get 5/10 or ½ or 0.5
miles. Therefore, Marsha finished 0.5 miles of the race.</span>
