In solving for the value of x in the equation 1331x^3 - 216 = 0, the steps are shown below:
1331x^3 - 216 = 0
(1331x^3 = 216) / 1331
x^3 = 216/1331
x = cube root (216/1331)
x = 6/11
Therefore, the value of x in the equation is 6/11.
Answer:
31.98
Step-by-step explanation:
78 * .41 = 31.98
Answer:
y = 10
Step-by-step explanation:
By definition, the internal angles of an equilateral triangle are all 60. So:
A = 5y + 10 = 60
5y + 10 = 60
5y + 10 - 10 = 60 - 10
5y = 50
5y/5 = 50/5
y = 10
33 sweets in a 7x to 4x ratio
7x + 4x = 33
11x = 33
x = 3
33 sweets can be put in a 7(3) to 4(3) ratio
which is a 21 to 12 ratio
so 21 sweets are yellow, and 12 sweets are purple to get the ratio of 7 to 4
