Step-by-step explanation:
-3+2y<4x
then
2y< 4x+ 3 (add both sides with 3)
y < 2x +3/2 ( divide both sides by 2 that is positif and we do not change the sens < )
Hope you understand.
Answer:

Step-by-step explanation:
<span>the value of the digit in the tenths place is 5/10 or 0.5
</span>
the value of the digit in the thousandth place
is 5/1000 = 0.005
0.5 = 100 x 0.005
Therefore, the value of the digit in the tenths place is 100 times as much as the value of the digit in the thousandth place
Answer
• A. Equation: 25(5 + x) = 325
,
• B. Answer: 8 dogs
Explanation
Given
• Charge to wash a dog: $25.
• She washed 5 dogs on Saturday and then some more on Sunday.
• She made $325 for the weekend.
Procedure
She charges $25 per wash, she made $325 for the weekend, and we know that on Saturday she washed 5 dogs, but we don't know how many she washed on Sunday. Thus, we have to build an equation in which the number of dogs washed on Sunday is represented by x (as we do not know the real number).
Considering that the total money made has to be equal to the multiplication of the charge times the dogs washed, the equation is:
![25(5+x)=325](https://tex.z-dn.net/?f=25%285%2Bx%29%3D325)
Then, we have to solve for x to know how many dogs did she wash on Sunday.
0. Multiplying the parenthesis
![125+25x=325](https://tex.z-dn.net/?f=125%2B25x%3D325)
<em>2. Subtracting 125 from both sides of the equation</em>
![125-125+25x=325-125](https://tex.z-dn.net/?f=125-125%2B25x%3D325-125)
![25x=200](https://tex.z-dn.net/?f=25x%3D200)
<em>3. Dividing both sides of the equation against 25</em>
![\frac{25x}{25}=\frac{200}{25}](https://tex.z-dn.net/?f=%5Cfrac%7B25x%7D%7B25%7D%3D%5Cfrac%7B200%7D%7B25%7D)
