We know that 3/10*20=6 students are eating salads.
We also know that 3/5*20=12 students are eating sandwiches.
Assuming each person only eats one thing, there are 20-12-6=2 students eating lunches other than salads or sandwiches.
Answer:
0.01364
Step-by-step explanation:
It is given that,
A store sells a 33-pound bag of oranges for $3.60 and a 55-pound bag of oranges for $5.25.
Price per pound of 33 pound bag is 3.60/33 = 0.10909 price per pound
Price per pound of 55 pound bag of oranges is 5.25/55 = 0.09545 price per pound
Difference between price per pound for the 33-pound bag of oranges and the price per pound for the 55-pound bag of oranges is :
D = 0.10909 - 0.09545
D = 0.01364
Therefore, this is the required solution.
Answer:
x = 50
Step-by-step explanation:
10x + 300 = 800
subtract 300 from both sides
10x = 500
divide each side by 10
x = 50
I think that x = 37/19
22x+54=−20+60x
Step 1: Simplify both sides of the equation.
22x+54=60x−20
Step 2: Subtract 60x from both sides.
22x+54−<u>60x</u>=60x−20−<u>60x</u>
−38x+54=−20
Step 3: Subtract 54 from both sides.
−38x+54−<u>54</u>=−20−<u>54</u>
−38x=−74
Step 4: Divide both sides by -38.
−38x/ <u>−38</u> = −74/<u>−38</u>
x=37/19
