x=26
Step-by-step explanation:
3x +12 =90
subtract 12 from each side
3x=78
divide 3 from each side
x=26
If you're completing the square the answer is in the image.
expression
x^2 + 5x - 5=ax^2+bx+c
a=1, b=5, c=-5, and you can solve it that way.
Answer:
39°
Step-by-step explanation:
IM assuming xyz is a triangle
180 - 113 - 28 = 67 - 28 = 39
<span>In order to find the average, you have to find the total, and then divide by the amount of days, which in this case is 5. The total is 395/5 = 79. Therefore, the average number of pies sold each day is 79</span>
Answer: 0.22 kilolitre
Step-by-step explanation:
First, let’s find the volume of the tank. We know the volume of a cylinder is represented by the equation V=πr^2h,
Radius = 1 m
Height = 7 cm = .07 m
The tank is 0.22 cubic meters
Now that we found the volume, we will try to find how many liters are in the tank.
1 cubic meter = 1 kilolitre
So, 0.22 cu. m = 0.22 kilolitre
