Answer:
10 voila (: ta réponse
Step-by-step explanation:
Proportion logic: 4/x = 5/1
P = 2(12+8)
P = 2(20)
P = 40
answer: <span>perimeter = 40 cm</span>
15.9 units is the answer plus just for the future you should try plotting them down and adding that to the question.
Answer:
y = 2x + 75
when x = 0, y = 75
when x = 11, y = 97
when x = 20.25, y = 115.5
when x = 58, y = 191
Step-by-step explanation:
To get the total number of pages she has read, y, after x minutes have elapsed. We will have to go by general form of equation which says
y = mx + b where m is the rate of change or simply the slope, which is 2 pages/minute. and y-intercept will be the number pages she has already read. Our equation will now be y = 2x + 75
The next step is to start substituting the numbers in to the equation
When X = 0
y = 2(0) + 75 = 75
when x = 11
y = 2(11) + 75 = 97
when x = 20.25
y = 2(20.25) + 75 = 115.5
when x = 58
y = 2(58) + 75 = 191
when x = 0, y = 75
when x = 11, y = 97
when x = 20.25, y = 115.5
when x = 58, y = 191
