145 divided by 7 =20.71
a little sketch on my answer <span />
Bearing in mind that an absolute value expression is in effect a
piece-wise function with two cases, thus
Answer:
x = 45/13, also x = 3 6/13
Step-by-step explanation:
is = equal sign
of = multiply
<u>Equation:</u>
To do this, you could easily do communitive property of multiplication, but to make it more understandable I will use reversing.
1. Simplify. Multiply - Divide.
2. Factor out common term 5.
3. Multiply both sides by 3.
4. Expand.
5. Add <em>10x</em> to both sides.
Simplify. <em>3x + 10x = 13x.</em>
Divide both sides by 13.
Mixed Number = 
.
You can also use distributive property. The formula for this problem is:

Answer/Step-by-step explanation:
We start with the variable "x". Let's call "x" Dan's full tank.
So we know that right now he has 1/5x or 1/5 of a full tank.
After adding 13 gallons, at the end, he has 7/10x, or 7/10 of a full tank
So we start with
(1/5)x + 13 = 7/10x
Let's subtract 1/5x from both sides
13 = 7/10x - 1/5x
Remember, we need to use common denominators to subtract, so 1/3 becomes 2/10
13 = 7/10-2/10x
Now we simplify to get
13 = 5/10x
Multiply the reciprocal of 5/10 to both sides which is 10/5
13 * 10/5= x
Answer is 26 gallons.
Therefore, Deon's tank can hold 26 gallons.
Answer:
Angle addition and the definition of a straight angle
Step-by-step explanation:
The definition of a straight angle is that that any straight angle must measure 180 degrees, Because youre adding the 3 angles of the graph your perfoming and angle addition and as they must measure 180 degrees, the three angles follow the rule of a straight angle.
