Add 6x and x to have 7x.
-1+6x+x=-1
7x-1=-1
+1=+1
7x=0
Divide 7x by 7 so the x can be left alone.
X=0
x+(x+2)=116. When simplified 2x+2=116. Now solve 2x=116-2.
2x= 114. Now divide to get x alone by dividing both sides by 2. X= 114÷2= 57. So now 116-57= 59 So, your two number 57 and 59. If you add them will be 116
Answer:
The largest number of pyramids she can make from 20 bars of chocolate is:
Step-by-step explanation:
Firstly, you must find the volume of the 20 bars of chocolate, remember that each bar contains 6 cubic inches of chocolate (6 in^3), so:
- Volume of the bars = 6 in^3 * 20
- <u>Volume of the bars = 120 in^3</u>
Now, you must find the volume of each pyramid, using the next formula:
- Volume of a pyramid = 1/3 B * h
Where:
<em>B = area of the square base.</em>
<em>h = height of the pyramid.</em>
How these values are given in the problem, we only replace the values in the formula:
- Area of a pyramid = 1/3 (1 in^2) * 2 in
- <u>Area of a pyramid = 2/3 in^3</u>
Finally, we divide the volume of the bars in the volume of each pyramid:
- Total number of pyramids = 120 in^3 / 2/3 in^3
- <u>Total number of pyramids = 180</u>
