Answer:
The full question is attached in the picture below.
The better price for the battery is given with the 6 pack.
(£ 0.47 per battery)
Step-by-step explanation:
If 8 batteries cost £ 3.99
This means that one battery is equal to
£3.99/8 = £ 0.49875 ≈ £ 0.50 per battery
The pack of 6 batteries costs £ 2.79
This means that one battery is equal to
£2.79/6 = £ 0.465 ≈ £ 0.47 per battery
Then, we can conclude than the 6 pack gives us a better price per battery
Answer:
x= 226/3 or 75.33333333333333333333333333333
Step-by-step explanation:
14y+82=6x-20
y=25
Sub y=25 into 14y+82=6x-20
14y+82=6x-20
14(25)+82=6x-20
Calculate as follows:
14(25)+82=6x-20
350+82=6x-20
432=6x-20
Add twenty to both sides:
432+20=6x-20+20
452=6x-0
452=6x
Divide both sides by 6
452=6x
452/6=6x/6
452/6=x
x= 226/3 or 75.33333333333333333333333333333
vol of wheat bag = 1.96 mater cuba so 258.72 / 1.96 = 392 bags I think this is the anwers. if wrong then sorry
A) .10 d + .25 q = 7.75
B) d + q = 40
Multiplying B) by -.10
B) -.10d -.10q = -4.0
Then adding this to A)
A) .10 d + .25 q = 7.75
.15q = 3.75
Quarters = 25
Therefore, dimes = 15
***************************************************
Double-Check
A) .10 d + .25 q = 7.75
A) .10 * 15 d + .25 * 25 = 7.75
A) 1.50 + 6.25 = 7.75
Correct!!
