For this problem, you are to multiply the numbers and add the exponents for the variables
10*3= 30
x*x^4= x^5
y^5*y^6= y^11
z^3*z^3= z^6
the answer to the question is 30x^5y^11z^6
25%
Explanation: it increased 4$ and 4$ is 25% of 16$
Answer:
I am not sure if this was the correct method to solve the question, however it gives the right results if you check it.
Step-by-step explanation:
3x+250+100=1250
3x= 900
x=300
yoga: 300, cross fit: 550 (300+250), gym: 400(300+100)
According to the associative property of equality: (a + b) + c = a + (b + c) we can see that the parenthesis do not mean anything when we are only doing addition.
So answers 1. and 3. are correct.
<em>Thanks Associative Property!</em>
