Answer:
see below
Step-by-step explanation:
54+2x=5x−3(2+6x) Given
Distribute the -3 to all the terms in the parentheses
54+2x=5x−6−18x Distributive property
54+2x=−13x−6 Combine like terms
Subtract 2x from each side
54=−15x−6 Subtraction Property of Equality
Add 6 to each side
60=−15x Addition property of equality
Divide each side by -15 ( or multiply each side by -1/15)
−4=x multiplication Property of equality
If G (gabriella) has 4 times as many as L (leona) then you would have G=4L when L=8, so Gabriella would have 32 erasers
The solution is x=1 and y=-2
Further explanation:
Given equations are:
Multiplying equation no. 1 with 2 will give us:
Eqn 3
From equation no 2:
Putting the value of y in eqn 3
The solution is x=1 and y=-2

Answer:
Step-by-step explanation:
we know that
The exponential function is of the form
where
y ---> the number of trucks
t ----> is the time in years
a ---> is the initial value (number of trucks for t=0)
b is the base
r is the rate
b=(1+r)
In this problem we have
substitute
we have the point (1,110)
For t=1 year, y=110 trucks
substitute
solve for b
The rate of growth is
the exponential equation is equal to
<u><em>Verify for the third point of the table</em></u>
For t=2 years
---->is correct
