Just move all terms to the left side and set equal to zero. Then, set each factor equal to zero.
a = 5,1
First lets write an equation to help us solve this.
26.25=3x+5.25
x=7
26.25 - 5.25 = 21.
21/3 = 7.
Option B: ![40\leq x\leq 100](https://tex.z-dn.net/?f=40%5Cleq%20x%5Cleq%20100)
Explanation:
Let the variable x denotes the number of cakes.
Shiloh has to earn $200 to meet her goal. So, she plans to sell her cakes at $5 each. The expression that represents this situation is given by
⇒![x=40](https://tex.z-dn.net/?f=x%3D40)
The minimum number of cakes that shilok has to sell to earn $200 is 40 cakes.
The maximum number of cakes are 100
Thus, the inequality that the number of cakes, Shilok can sell to meet her goal is ![40\leq x\leq 100](https://tex.z-dn.net/?f=40%5Cleq%20x%5Cleq%20100)
Simply plug in numbers!! (3x-1)(5)=55
15x-5=55
15x=60
x=4
hope this helps :)
