Answer:
not really sure for number one
1. 1.56y × 3.9x
2. 4.8x + 9.6y
Answer:
x = 1
Step-by-step explanation:
It is given that,
∠A and ∠B are vertical angles.
∠A = (5x – 4) and ∠B = (2x – 1)
We need to find the value of x.
We know that, the vertical angles are equal. So,
∠A=∠B
(5x – 4)=(2x – 1)
Taking like terms together,
5x-2x = 4-1
3x=3
x = 1
So, the value of x is equal to 1.
The constant of proportionality is equal to k in y=kx. In y=10x, the k value is 10.
Final answer: C. 10
12×12×12×12×12 is equivalent to 12^5 (a^b means a is to be written down B times all being multiplied.)
