<span>Since there are 20 chairs and should be arrange into 5
equal rows. So the number of chairs in each row is equal to 20 / 5 which equal
to 4. so let x represent a chair in the array. so the drawing should be like:
x x x x
x x x x
x x x x
x x x x
x x x x </span>
Answer:
Expressions are not meant to be solved, they are more so to be evaluated and explained.. a visual differenceis that there is no equal sign or answer written, an equation is solved and has an equal answer. EXPR: (2 x 13) + 9 EQU: (19 x 12) + 3= 231
Yep that's the right answer man great job!
Answer:
c)3/2(8/7)^x
Step-by-step explanation:
Evaluate the functions.
1. Because 7/4 > 1 and the exponent is positive,
the function does not decay.
2.Because 4/5 < 1 and the exponent is negative,
the function does not decay.
3. Because 8/7 > 1 and the exponent is negative,
the function decays.
4. Because 9/2 > 1 and the exponent is positive,
the function does not decay.
A composite plot the functions verifies the answer.
If all the x's are exponents, then 3/2 (8/7)^-x is the only one that decays as x gets bigger. That's because the base is greater than 1 and the x is negative.

Answer:
13.89 m/s
Step-by-step explanation:
Velocity = displacement = time
75 km = 75000 m
1.5 hours = 5400 sec
applying the formula
velocity = 75000 m= 5400 s = 13.89 m/s
