Answer: ![V=90](https://tex.z-dn.net/?f=V%3D90)
Let us take the case of 7 pounds for $8.47 first.
7 pounds of a product costs = 8.47 dollars
Then
1 pound of the same product will cost = (8.47/7) dollars
= 1.21 dollars
Now let us take the case of 9 pounds for $11.07
9 pounds of a product costs = 11.07 dollars
Then
1 pound of the same product will cost = (11.07/9) pounds
= 1.23 dollars
So from the above deductions we can see that 9 pounds for $11.07 is a better buy than 7 pounds for $8.47. I hope the procedure is clear enough for you to understand. In future you can use this method for solving similar problems.
Answer:
C) 15
D) 287
Step-by-step explanation:
If you look up the definition of integers you see:
integer
[ˈin(t)əjər]
NOUN
integers (plural noun)
a whole number; a number that is not a fraction.
"integer values"
a thing complete in itself.
So C and D are correct.
Y=1
Explanation:
You have to plug 2+x into the y of the first equation. After you solve that you should get-1 as the answer for x so you plug -1 into the x of the second equation and the value of y would be 1.
Answer:
X=50 hope this helps:)
Step-by-step explanation:
90+110=200
360-200=160
160=3x+10
150=3x
X=50
