Answer:
Explanation:
Given the simultaneous equation we are to find the values of x and y
3x-2y = 14 ..... ×1
5x-y = 32...... ×2
Using elimination method, the equation becomes
3x-2y = 14
10x-2y = 64
.subtract
3x-10x = 14-64
-7x = -50
x = -50/-7
x = 7 1/7
Substitute x = 50/7 into eqn 2
From 2;
5(50/7)-y = 32
250/7 - y = 32
y = 250/7-32
y = (250-224)/7
y = 26/7
Hence (x,y) = (50/7, 26/7)
Odysseus told Penelope that because when Telemachus was able to grow facial hair it meant that he was becoming a man and that many years had passed, meaning he probably was dead. As for the disguise part, I suppose it was because beards cover a large portion of the face and make you look tougher, more masculine, and gruff.<span />
While working with Belen, you counted out ten bears on one plate.While counting, you spaced the bears apart from each other. On another plate, you counted out another ten bears and while counting, you placed them practically on top of each other in a pile. You asked the child, "Does one plate have more?" Belen nodded "yes" and pointed to the plate with the ten bears spread widely apart. This shows that Belen is in the formal operational stage of development.
Answer: Option (B) is correct
<u>Explanation: </u>
The formal operational stage of development begins at the age of twelve and lasts until adulthood i.e 18 years. It is the last stage of Jean Piaget's theory of cognitive development. A child tries to solve the problem systematically.They try to make use of logic as much as they can.
Children at this stage very hurriedly plan about the systemic method which can be used in solving the problem. They learn to reason at this stage. They learn deductive reasoning which helps them to get the outcome. This deductive reasoning plays a very important role in math.
