9/14 stays the same
2/7 turns into 4/14
1/ into 7/14
all of them added is 20/14
simplified is 1 3/7
A. 314 sq cm
Explanation: pi•r^2
3.14 x 10^2
3.14 x 100 =314
Answer:
Experiment
Step-by-step explanation:
Base on the scenario been described in the question, where Mrs. Reynolds has many (over a hundred) houseplants of many different types including philodendrons, ferns, spider plants, cacti, tomatoes, pineapples, this is a typical example of experiment .
An experiment is a procedure carried out to support, refute, or validate a hypothesis. Experiments provide insight into cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated
Sure, each of the following lines.
8x-6+3x-1
11x-6-1
and, 11x-7
The solution is (5, 15)
Multiply the second equation by 2 and then add through.
3x + 2y = 45
8x - 2y = 10
-----------------
11x = 55
x = 5
Then plug in to get the y value
3(5) + 2y = 45
15 + 2y = 45
2y = 30
y = 15
