Congruent since all angles are equivalent to each other.
Answer:
Psychology textbooks = 98 and physics textbooks = 294
Step-by-step explanation:
Let there are x psychology textbooks sold.
No of physics textbooks sold = 3x
ATQ,
A textbook store sold a combined total of 392 physics and psychology textbooks in a week.
x + 3x = 392
4x = 392
x = 98
It means there are 98 psychology textbooks sold and 3x = 3(98) = 294 physics textbooks sold.
6 cakes ... £2.40
10 cakes ... £x = ?
If you would like to know how much do 10 cakes cost, you can calculate this using the following steps:
6 * x = 10 * 2.40
6 * x = 24 /6
x = 24/6
x = £4
Result: 10 cakes cost £4.
You can compare properties of two functions each represented in a different way by saying them out loud (verbally), seeing them as they are by numbers (numerically), and even how they are seen (visually).
