Answer:
x + 11 = 10
Step-by-step explanation:
Let the required number be x.
Quotient = x + 4 + 7 = 10
= x + 11 = 10
Answer:
Depends on your sales tax rate where you live.
Lets call your sales tax rate X%
then it would be multiplied b y the $850 and that would be added back to the $850.
Example:
If your sales tax rate were 10%
then it would be .10 x $850 =$85
Now add the $85 to the $850 and your total would be $945
P.S. Some localities offer sales tax free weekends for school supplies.

Answer:
5670 cm^3 or 5670cm cubed
Step-by-step explanation:
Original sides-
12, 15, 18
After increasing by 3-
15, 18, 21
Finding the volume of a rectangular prism is length*width*height.
=15*18*21
=270*21
=5670
Therefore, the volume of the new prism is 5670cm cubed.

Answer:
14, 15,16
Step-by-step explanation:
lets take "x" as the first integer
so since all the numbers are consecutive we can take integer number one as:
x
integer #2: x+1
integer#3:x+2
so
x+x+1+x+2=45
3x+3=45
3x=42
x=14
Hope this helps!
Answer:
<h3>
present age of son = 10 </h3><h3>
present age of father = 40</h3>
Step-by-step explanation:
Let, present age of son be 'x'
present age of father be 'y'
y = 4x→ equation ( i )
After five years,
Son's age = x + 5
father's age = y + 5
According to Question,
![y + 5 = 3(x + 5)](https://tex.z-dn.net/?f=y%20%2B%205%20%3D%203%28x%20%2B%205%29)
Put the value of y from equation ( i )
![4x + 5 = 3(x + 5)](https://tex.z-dn.net/?f=4x%20%2B%205%20%3D%203%28x%20%2B%205%29)
Distribute 3 through the parentheses
![4x + 5 = 3x + 15](https://tex.z-dn.net/?f=4x%20%2B%205%20%3D%203x%20%2B%2015)
Move variable to L.H.S and change it's sign
Similarly, Move constant to R.H.S. and change its sign
![4x - 3x = 15 - 5](https://tex.z-dn.net/?f=4x%20-%203x%20%3D%2015%20-%205)
Collect like terms
![x = 15 - 5](https://tex.z-dn.net/?f=x%20%3D%2015%20-%205)
Calculate the difference
![x = 10](https://tex.z-dn.net/?f=x%20%3D%2010)
Now, put the value of X in equation ( i ) in order to find the present age of father
![y = 4x](https://tex.z-dn.net/?f=y%20%3D%204x)
plug the value of X
![= 4 \times 10](https://tex.z-dn.net/?f=%20%3D%204%20%5Ctimes%2010)
Calculate the product
![= 40](https://tex.z-dn.net/?f=%20%3D%2040)
Therefore,
Present age of son = 10
present age of father = 40
Hope this helps..
Best regards!!
