Answer: When you combine like terms in a algebraic expression, you do not add the exponents! When you combine like terms in an equation, such as a^2 and 4a^2, you only combine the numbers, not the exponents. The exponent attached to the number stays the same. a^2 and 4a^2 would be 5a^2.
Answer:
Step-by-step explanation:
Event of not rolling a 5= {1,2,3,4,6}
P(not rolling a 5) = 5/6
Answer:
x = 40
Step-by-step explanation:
5= 1/5x -3
Add 3 to each side
5+3= 1/5x -3+3
8 = 1/5x
Multiply by 5 to isolate x
5*8 = 1/5x *5
40 =x
the equation of the line has form
y=kx+b
, so
The second line is parallel to the first and runs 7 units lower, so b=5
