Answer: 7 cubic meters
Step-by-step explanation:
you add
Thats 95 cents becuase nickel equals 5 and dime equals 10
so 5x5=25
and 7x10=70
so 70+25=95 cuz 0+5=5 and 7+2=9
Step-by-step explanation:
20:100=x:$38.55
x=20×$38.55/100=7,71
Answer: x^#22
Step-by-step explanation: Cancel the common factor of
x^56 and x^24.
So your answer is x^32 I’m trying my best to explain the answer.
Answer:
A salad costs $2.50
A sandwich costs $4.50
A drink costs $1.25
Step-by-step explanation:
Let x represent the salad, y represent the sandwich, and z represent the drink.
Since three salads, two sandwiches, and one drink cost $17.75:
3x + 2y + z = 17.75 (1)
Since one salad, one sandwich, and three drinks cost $10.75:
x + y + 3z = 10.75 (2)
Since a salad costs twice as much as a drink:
x = 2z (3)
Multiply the equation 2 by -2 then, sum the equation 1 and equation 2:
-2x - 2y - 6z = -21.50
3x + 2y + z = 17.75
→ x - 5z = -3.75
Replace the x with 2z using equation 3:
2z - 5z = -3.75
-3z = -3.75
z = 1.25
x = 2z → x = 2.50
x + y + 3z = 10.75 → 2.50 + y + 3.75 = 10.75 → y + 6.25 = 10.75 → y = 4.50
