Answer:
1. About 9 left. 2. £21 left
Step-by-step explanation:
First, you do 65 ÷ 3 = 21.7 if rounding to the tenths, 21.67 if to the hundredths, and so on. Then you do 21.67 - 12 = 9.67. But since it is cards, I would say about 9 left.
First you add the £20 to the £70 to get £90. then you multiply 7×3 to get £21 spent on books. After that, multiply 12×4 to get £48 spent on games. then do 48 + 21 = 69. 90-69= 21.
Here is the equation....
(70+20)-[(7×3)+(12×4)] = £21
For this case we must find the unit cost (dollars per pound) of each site and then compare.
We take into account that:
1kg equals 2.205 pounds
So, we have:
Site 1:

Site 2:

So, the unit cost is:

Thus, the best deal is on site 2.
ANswer:
The best deal is on site 2.
A is the 4
B is the 5
and C is also 4.
A is always the number in front of x^2. B is always the number i front of the normal x, and C is the number that is on the other side of the equal sign!
(-1,8) is the correct answer I’m pretty sure
We have to use the following formula which is

Given values of F and m are 7.92 Newtons and 3.6 kilograms .
Substituting these values in the formula, we will get

To solve for a, we have to divide both sides by 3.6 that is

And that's the required answer .
