Answer:
Answer: The car will travel 29 1/3 miles in 44 minutes, 40 miles in an hour
Step-by-step explanation:
1 1/2x2 1/4 = 2/3
Multiply that by your minutes (25) and you will get 16.6666
Convert to a fraction and u will get 16 2/3 miles in 25 minutes
40 miles in an hour
First, let's multiply the first equation by two on the both sides:
<span>8x + 7y = 39 /2
</span>⇒ 16x + 14y = 78
Now, the system is:
<span>16x + 14y = 78
</span><span>4x – 14y = –68
</span>
After adding this up in the column:
(16x + 4x) + (14y - 14y) = 78 - 68
20x = 10
⇒ x = 10/20 = 1/2
y can be calculated by replacin the x:
<span>8x + 7y = 39
</span>⇒ 8 · 1/2 + 7y = 39
4 + 7y = 39
7y = 39 - 4
7y = 35
⇒ y = 35 ÷ 7 = 5
Answer:
x=5/3 your answer right answer
You can think of the absolute value as the distance from 0.
10 and -10 are both 10 units away from 0.
The <span>graph most accurately represents this scenario is the graph that started at (0,0) and goes up diagonally upward to a point ( 0.5 hr, y1). then goes horizontally straight for 2 hours because it does not travel just shopping (2.5, y1). then another diagonally upward to (2.75, y2). then another horizontal for 1 hr. (3.75, y2)</span>
