SALES Cars and trucks are the most popular vehicles. Last year, the number of cars sold was 39,000 more than three times the number of trucks sold. There were 216,000 cars sold last year. Write an equation that can be used to find the number of trucks, t, sold last year.
Answers
Given :
Miki has 104 nickels and 88 dimes. She wants to divide her coins into groups where each group has the same number of nickels and the same number of dimes.
There were 216,000 cars sold last year.
To Find :
Equation that can be used to find the number of trucks, t, sold last year.
Solution :
Let , number of truck sold is t and number of car sold is c.
It is given that the number of cars sold was 39,000 more than three times the number of trucks sold.
So ,
[tex]c=3t+39000\\\\t=\dfrac{c-39000}{3}[/tex]
Putting value of c = 216000 in above equation , we get :
[tex]t=\dfrac{c-39000}{3}\\\\t=\dfrac{216000-39000}{3}\\\\t=59000[/tex]
Hence , this is the required solution .
An equation is formed of two equal expressions. An equation that can be used to find the number of trucks, t is 216,000 = 39,000 + 3t.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given that in the Last year, the number of cars sold was 39,000 more than three times the number of trucks sold. Therefore, we can write,
Number of cars sold = 39,000 + 3 times the number of trucks sold
Number of cars sold = 39,000 + 3t
where t represents the number of trucks sold.
Given that number of cars sold is 216,000. Therefore, the equation can be solved for t as shown below.
216,000 = 39,000 + 3t
216,000 - 39,000 = 3t
3t = 177,000
t = 177,000 / 3
t = 59,000
Hence, an equation that can be used to find the number of trucks, t is 216,000 = 39,000 + 3t.

Hey there!☺
[tex]Answer:\boxed{a=\frac{b-u}{k}}[/tex]
[tex]Explanation:[/tex]
[tex]u=b-ak[/tex]
In our first step, we will flip the equation:
[tex]-ak+b=u[/tex]
Now add -b to both sides:
[tex]-ak+b+-b=u+-b\\-ak=-b+u[/tex]
In our last step, we will divide both sides by -k:
[tex]\frac{-ak}{-k}=\frac{-b+u}{-k}\\a=\frac{b-u}{k}[/tex]
a=b-u/k is your answer.

4x-7=7x-61 solve for x
Answers
Answer:
x = 18Step-by-step explanation:
4x - 7 = 7x - 61
Subtract 7x from both sides
That's
4x - 7x - 7 = 7x - 7x - 61
- 3x - 7 = - 61
Add 7 to both sides
We have
- 3x + 7 - 7 = - 61 + 7
- 3x = - 54
Divide both sides by - 3
That's
[tex] \frac{ - 3x}{ - 3} = \frac{ - 54}{ - 3} [/tex]We have the final answer as
x = 18Hope this helps you
Answer: 18
Step-by-step explanation:
4x - 7 = 7x - 61
+61 +61
4x + 54 = 7x
divide both sides by 4
x + 27/2 = 7/4x
-x -x
27/2 = 3/4x
divide both sides by 3/4
x = 18
