Answer:
discount of 50% on one shirt, which inequality can be used to find the maximum number of shirts, n, that she can buy?
Step-by-step explanation:
has $210 to spend on clothes. She wants to buy a pair of shorts and some shirts. The cost of a pair of shorts is $25, and the cost of a shirt is $40. If she gets a discount of 50% on one shirt, which inequality can be used to find the maximum number of shirts, n, that she can buy?
Answer:
Step-by-step explanation:
![\sqrt[3]{x+4}+\sqrt[3]{2x +8}=0\\\\\sqrt[3]{x+4}= -\sqrt[3]{2x + 8}\\\\(x +4)^{\frac{1}{3}}=-(2x+8)^{\frac{1}{3}}\\\\](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%2B4%7D%2B%5Csqrt%5B3%5D%7B2x%20%2B8%7D%3D0%5C%5C%5C%5C%5Csqrt%5B3%5D%7Bx%2B4%7D%3D%20-%5Csqrt%5B3%5D%7B2x%20%2B%208%7D%5C%5C%5C%5C%28x%20%2B4%29%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D%3D-%282x%2B8%29%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D%5C%5C%5C%5C)
Take cube,
![[(x+4)^{\frac{1}{3}}]^{3} =- [(2x +8)^{\frac{1}{3}}^{3}]\\\\(x+4)^{3*\frac{1}{3}}=-(2x + 8)^{3*\frac{1}{3}}\\\\](https://tex.z-dn.net/?f=%5B%28x%2B4%29%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D%5D%5E%7B3%7D%20%3D-%20%5B%282x%20%2B8%29%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D%5E%7B3%7D%5D%5C%5C%5C%5C%28x%2B4%29%5E%7B3%2A%5Cfrac%7B1%7D%7B3%7D%7D%3D-%282x%20%2B%208%29%5E%7B3%2A%5Cfrac%7B1%7D%7B3%7D%7D%5C%5C%5C%5C)
x + 4 = - (2x + 8)
x +4 = 2x *(-1) + 8 *(-1)
x+ 4 = -2x - 8
x +2x+4 = - 8
3x + 4 = - 8
3x = - 8 -4
3x = -12
x = -12/3
x = -4
Answer:
-9
Step-by-step explanation:
Let the letter o represent the original price.
17.85 = o + (o*1.10)
17.85 = 2.10 * o
o = 17.85/2.10=8.5
The original price was $8.50
Answer:
625
Step-by-step explanation:
5x5x5x5=625
you multiply five four times because there are four groups of three in twelve
