Answer:
9 inches
Step-by-step explanation:
Do the question algebraically, represented by this equation:
let x be the shorter piece
x + (x + 8) = 26 (longer piece is 8 units longer)
Remove brackets
x + x + 8 = 26 Combine like terms
2x + 8 = 26 Start isolating "x"
2x + 8 - 8 = 26 - 8 Subtract 8 from both sides
2x = 18
2x/2 = 18/2 Divide both sides by 2
x = 9 shorter piece
The shorter piece would be 9 inches.
If you needed the longer piece too:
longer piece = x + 8
x + 8
= 9 + 8
= 17
The longer piece would be 17 inches.
Check your answer:
Longer + Shorter = 26 Substitute the lengths
17 + 9 = 26 Add
26 = 26 same number
LS = RS left side equals right side
The answer is correct.
The expression 0.15(x-350) would be the proper equation.
Answer:
and
Step-by-step explanation:
Dawn wants to compare the volume of a basketball with the volume of a tennis ball.
Now, if the radius of the basketball is R and that of the tennis ball is r, then the formula that can be used to determine the volume of each ball will be
and
Now, dividing V by v we can compare the volume of the basketball and the tennis ball. (Answer)
Answer:
a) Linear function
b) Linear function
c) Exponential function
d) Exponential function
Step-by-step explanation:
a) The number of hours in a day increases constantly with 60 minute intervals
b) Constant speed = same distance traveled per given time - so it's linear
c) If a population doubles every y years, it means that the population is being raised exponentially - not at a constant rate, but more each year
d) Same as c
