Step-by-step explanation:
Tamu ran for 30 minutes.
Calories burnt by Tamu = 170 calories
Unit rate =
Unit rate =
Unit rate = 5.66 calories per minute
Therefore,
Tamu burnt 5.66 calories per minute.
Answer:
Step-by-step explanation:
Let the horizontal distance is x
<u>Use tangent to solve this:</u>
- tan 30° = 6/x
- x = 6 / tan 30°
- x = 10.4 mi (rounded)
136 - 56 = 80 songs kept
Ratio of songs kept to songs deleted is:
80:56
Simplify by dividing each number by 8:
The simplest form is: 10/7
The solution to the given simultaneous equation is; (-9, -10)
<h3>What is the solution to the simultaneous equations?</h3>
We want to solve the simultaneous equations;
y = ²/₃x - 4 ----(1)
y = ⁴/₃x + 2 ----(2)
Subtract eq 1 from eq 2 to get;
⁴/₃x - ²/₃x + 2 + 4 = 0
²/₃x = -6
x = (-6 * 3)/2
x = -9
Thus;
y = ⁴/₃(-9) + 2
y = -10
Thus, the solution to the given simultaneous equation is; (-9, -10)

Answer:
Step-by-step explanation:
Let the numbers be x , y
Sum of two numers = -7
x + y = -7------------(I)
Two times the first number equals 4 the second number.
2x = 4y ----------(II)
Divide both sides by 2
x = 2y
Subtitute x = 2y in equation (I)
2y + y = -7
3y = -7
y = -7/3
Plugin y = -7/3 in equation (II)
