Step-by-step explanation:
In order to find the number of solutions, we have to expand both sides out first.

First, expand 3(x-2), which will obtain 3x-6.
Next, expand (1/2)(6x-2), which gives 3x - 1.
The result at this point should be as shown below:

Now, we would shift all x terms to the left and all number terms to the right.

After simplifying, the final equation would be:

This is a linear equation and it has one solution.

Answer : x=3
Step-by-step explanation:
Explanation:
2x+3=9
We want to find the variable x, so we have to make it alone. To do so, first subtract 3 from both sides of the equation:
2x+3 − 3=9 − 3
2x=6
Now divide both sides by 2:
2x2=62
So the final answer is:
x=3
Answer:
Step-by-step explanation:
4/5 x - 2 > 3/10 * 2x
4/5 x - 2 > 3/5 x
4/5 x - 2 - 3/5x> 0
1/5x > 2
x > 10
Answer:
The number of ounce of topping that can be get is 4 .
Step-by-step explanation:
Given as :
The cost of a sundae = $3
The cost for each extra ounce of toppings = $0.50
Let The number of ounce of topping = n
The total spending cost on sundae with n extra topping = $5
Now, According to question
The total spending cost on sundae with n extra topping = The cost of a sundae + The number of ounce of topping × The cost for each extra ounce of toppings
Or , $3 + n × $0.50 = $5
or, 3 + 0.50 n = 5
or , 0.50 n = 5 - 3
or, 0.50 n = 2
∴ n = 
I.e n = 4
So, The number of ounce of topping = n = 4
Hence The number of ounce of topping that can be get is 4 . Answer
