Hi sorry for the late response, I know the assignment was due at 5pm today but anyway here is the answer.
System:
<em>d= 5(0.75-t)</em>
<em>d= 20t</em>
<em>20t = 3.75 -5t</em>
Define Variables:
<em>d = how far Carol Skied</em>
<em>t = time it took Carol to go up/down</em>
Solve:
20t = 3.75 -5t
20t + 5t = 3.75 -5t + 5t
25t = 3.75
25t/25 = 3.75/25
t = 0.15
<u><em>Now we plug in the time into the Distances:</em></u>
20t = 3.75 - 5t
20(0.15) = 3.75 - 5(0.15)
3 = 3.75 - 0.75
3 = 3
Solution as Sentence:
<u><em>Carol Skied 3 miles</em></u>
<u><em /></u>
Answer:
C
Step-by-step explanation:
15 - 9 = 6, So I then looked at each answer to see which had a difference of 6 and 35 - 29 = 6.
GOOD LUCK IN MATH!
A= y*z- w*(z-x)=10*5-5*(5-3)=50-5*2=50-10=40 in.^2
B is the answer
Answer: 59 degrees
--------------------------------------------------------------
--------------------------------------------------------------
Work Shown:
We have the three angles:
angle A = (3x+2) degrees
angle B = (2x+7) degrees
angle C = 41 degrees
Rule: for any triangle, the three angles add up to 180 degrees
(angle A) + (angle B) + (angle C) = 180
(3x+2) + (2x+7) + (41) = 180
3x+2 + 2x+7 + 41 = 180
(3x+2x)+(2+7+41) = 180
(5x)+(50) = 180
5x+50 = 180
5x+50-50 = 180-50
5x = 130
5x/5 = 130/5
x = 26
Now use this x value to find the measure of angle B
angle B = (2x+7) degrees
angle B = (2*x+7) degrees
angle B = (2*26+7) degrees
angle B = (52+7) degrees
angle B = 59 degrees
Side Note: Angle A is 80 degrees (3x+2 = 3*26+2 = 78+2 = 80)
Another thing to note: A+B+C = 80+59+41 = 180
46+19+54= 119, so the answer is 119
