Answer:
25 minutes
Step-by-step explanation: 20 divided by 8 equals 2.5 so she take 2 and a half minutes per question. 2.5 plus 2.5 equals 5 so just add five minutes on her original time. 25 minutes
The correct answer is 4.8 hours
Explanation:
This mathematical problem can be solved by using the rule of three, which involves finding an unknown value by using three related values. The process is shown below:
1. It is known a fully charged battery (100% battery) lasts 16 hours. This can be represented as 100 = 16. But it is not know how much a 30% battery last; this can be represented as 30 = x.
2. Write all the values
100 = 16
30 = x
3. Cross multiply to create an equation and solve the equation
100 x = 48
x = 480 / 100
x = 4.8
Answer:
In this illustration, the idea is that you have to produce something that performs both the right-hand side of the comparison and the left side to be similar to individually other which provides you an infinite number of solutions. so if you have 5x-8 on the left-hand, you need 5x-8 on the right-hand for everything to eliminate and end up with 0=0.

Answer:
324° is the correct answer
Answer:
y = x - 2
Step-by-step explanation:
To write the equation in the form y = mx + b, find the value of slope (m) and y-intercept (b) of the graph.
Slope (m) = change in y/change in x
Using two points on the line, say (0, -2) and (2, 0),
Slope (m) = (0 -(-2))/(2 - 0)
m = 2/2
m = 1
y-intercept (b) = -2 (this is the point where the y-axis is intercepted by the line, at this point, x = 0)
✔️To write the equation, substitute m = 1 and b = -2 into y = mx + b
y = 1(x) + (-2)
y = x - 2
