Answer:
this is what i found
Step-by-step explanation: Multiply k and 9
Multiply k and 1
The k just gets copied along.
The answer is k
k
9*k evaluates to 9k
Multiply m and 9k
Multiply the m and k
Multiply m and k
The m just gets copied along.
The k just gets copied along.
The answer is mk
mk
9*k*m evaluates to 9mk
Multiply u and 9mk
Multiply the u and mk
Multiply u and mk
The u just gets copied along.
The m just gets copied along.
The k just gets copied along.
The answer is umk
umk
9*k*m*u evaluates to 9umk
Multiply l and 9umk
Multiply the l and umk
Multiply l and umk
The l just gets copied along.
The u just gets copied along.
The m just gets copied along.
The k just gets copied along.
The answer is lumk
lumk
9*k*m*u*l evaluates to 9lumk
Multiply t and 9lumk
Multiply the t and lumk
Multiply t and lumk
T
I think 3.16 I said I think
(z + 6) / 3 = 2z / 4
this is a proportion, so we cross multiply
(3)(2z) = 4(z + 6)
6z = 4z + 24
6z - 4z = 24
2z = 24
z = 24/2
z = 12 <==
4004 + 50.50t = 300.75t
4004 = 300.75t - 50.50t
4004 = 250.25t
4004 / 250.25 = t
16 = t <=== they charge the same at 16 tons
300.75(16) = 4812 <== they cost the same
So for a you need to add up all the numbers and for b you need to multiply all the numbers
Can you help me I posted a new question that is worth 50 points
