Answer:
1) $283.50
2) 65.21 meters.
Step-by-step explanation:
Part 1)
We know that a spool of ribbon holds 6.75 meters.
A craft club buys 21 spools.
So, the total length of ribbon bought is:

Each meter costs $2. So, the total cost will be:

Part 2)
A spool holds 6.75 meters.
We bought 21 of them, so that total length we have is 141.75 meters.
The club used 76.54 meters.
So, the amount of ribbon that is left is represented by:

Subtract:

So, 65.21 meters of ribbon will be left.

Like terms are those terms that are having the same variables and order. The simplified form of the given equation 7z+2=8+2z+1z is 4z=6.
<h3>What are Like terms?</h3>
Like terms are those terms that are having the same variables, also the variables are of the same order as well.
for example, 25x and 5x are like terms; 30xy and 7xy are like terms, 9x³ and 4x² are not like terms, etc.
The given equation to us is 7z+2=8+2z+1z, simplifying the equation we will get,

Hence, the simplified form of the given equation 7z+2=8+2z+1z is 4z=6.

Answer:
f(n) = 16(0.5)ⁿ⁻¹
Step-by-step explanation:
Find f(1) for each option.
a) f(1) = 16(0.5)¹⁻¹ = 16
b) f(1) = 32(0.5)¹⁻¹ = 32
c) f(1) = 16(0.5)¹ = 8
d) f(1) = 32(0.5)¹⁺¹ = 8
Only the first option matches the table.
