<em /><em>PURPLE MARBLES=P
WHITE MARBLES=W
</em>First, write out an equation showing the number of purple marbles.
P=5W-6
Then, write out the main equation.
W+P=96
W+5W-6=96
Add 6 to both sides.
W+5W=102
6W=102
Divide both sides by 6
W=17
Now that we know there are 17 white marbles, we can go back to the equation about how many purple marbles there are.
P=5W-6
Plug in the value for W, which is 17.
P=5(17)-6
P=85-6
P=79
To make sure your answer is correct, check your work by plugging in the values for P+W=96.
79+17=96
Answer: There are 79 purple marbles.
X=18
Explanation:
The sum of the 3 angles in a triangle is 180∘
hence , the sum of the 3 angles given must equal 180
We can form an equation
2x + 3x + 5x = 180 ⇒10x=180⇒x=180/10
x=18
2(x) = 2(18)=36
3(18)=54
5(18)=90
Answer:
1/8 cm^3
Step-by-step explanation:
If s=1/2 and V=s^3, then V=1/2^3=8. Therefore the volume of the cube is 1/8cm^3.
Answer:
84/6=14. Each side is 14 because there are 6 sides to a hexagon.
