Jalen bought 4 bottles of water, 2 bags of cashews, and a fruit salad. the cost of the fruit salad was $5. this expression was used to represent the amount jalen should pay. 4x +2x +5 based on the expression, the cost of each bottle of water is the cost of each bag of cashews.

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
