Answer:
Step-by-step explanation:
Factors
- A term in multiplication for an entire variety by which a bigger complete quantity may be divided
- A divisor is an integer that evenly divides a range without leaving the rest
- Factorization is the decomposition of an item right into a product of other objects
- Integer factorization, the manner of breaking down a composite quantity into smaller non-trivial divisors
- A coefficient, a multiplicative thing in an expression, usually more than a few
- The act of forming a component institution or quotient ring in summary algebra
- A von Neumann algebra, with a trivial center
- Factor (graph principle), a spanning subgraph
- Any finite contiguous sub-sequence of a word in a group concept
(b)/(7.8)=-2.15
Multiply each term in the equation by 7.8.
(b)/(7.8)*7.8=-2.15*7.8
Cancel the common factor of (1)/(7.8).
1b=-2.15*7.8
Multiply -2.15 by 7.8 to get -16.77.
1b=-16.77
Divide each term in the equation by 1.
(1b)/(1)=-(16.77)/(1)
Cancel the common factor of 1.
b=-(16.77)/(1)
Divide -16.77 by 1 to get -16.77.
b=-16.77

Answer: The correct answer is 94 cm.
Step-by-step explanation:
wingspan length
60 meters 70.5 m
----------------- = ----------------
80 cm x
Cross multiply
(60 m)x = (70.5 m)(80 cm)
Solve for x by dividing both sides of equation by 60 m:
x = (70.5 m)(80 cm) / (60 m) = 94 cm
The length of the model is 94 cm.

Using these variables, we can set up equations.
3x + 5y = 42
9x + 7y = 72
We have here a system of equations, where we have two or more equations with two or more different variables. We use the elimination method to solve for the variables.
Multiply eq1 by 3. Keep eq2.
9x + 15y = 126 eq1
9x + 7y = 72 eq2
Subtract eq2 from eq1 to eliminate the x terms.
8y = 54
y = 6.75
213.5*5=1067.5
The length of the actual train car is 1067.5 ft.
