To find this answer you will write the rate given as a unit rate per pound. Divide the get this.
$6.60/60 pounds = $0.11/ 1 lb.
This is the same as $0.11 per 16 ounces. Divide again to get a unit rate per ounce.
$0.11/16 = $0.006875 or $0.007 or 0.7 cents per ounce
Choice D is correct, but it should say per ounce not per pound.
Answer:
1) D: all real/(-inf, +inf) R: all real/(-inf, +inf)
2) x 5 or (-inf, 5)U(5,+inf)
Step-by-step explanation:
1) This is a linear equation, meaning that it has all real numbers all throughout.
This implies that you can plug in any x value and it will have a definite y value.
Domain is all reals or (-inf, +inf)
Range is all reals or (-inf, +inf)
2) We can see that if you plug in the number 5 for x, you would get 5-5 = 0 for the denominator. We can not divide a number by 0, therefore the domain is
x can not equal to 5 or (-inf, 5)U(5,+inf)
Answer:
40 cheesburgers
Step-by-step explanation:
Answer:
8 pounds of apples.
Step-by-step explanation:
5 pies need 2 pounds of apples.
so 1 pie needs 2/5 pounds
- and 20 pies needs 20 * 2/5
= 40/5
= 8 pounds of apples.
2x - 3y = 6
-3y = 6 - 2x
y = -2 + 2/3x
