To solve, divide the dollars by the pounds of peanuts to find the cost per pound:
12/8 =1.5
So, it cost $1.50 per pound of peanuts.
Hope this helps!
The sequence is defined as
an = 3an - 1 + 7
This means that
a2 = 3(a(2 - 1) + 7
a2 = 3a1 + 7
From the information given ,
a1 = - 4
Thus,
a2 = 3 * - 4 + 7 = - 12 + 7
a2 = - 5
a3 = 3(a(3 - 1) + 7
a3 = 3a2 + 7
a3 = 3 * - 5 + 7 = - 15 + 7
a3 = - 8
a4 = 3(a(4 - 1) + 7
a4 = 3a3 + 7
a4 = 3 * - 8 + 7 = - 24 + 7
a4 = - 17
Thus, the first four terms of the sequence are
- 4, - 5, -
Find the unit rate.
39/6 = 6.5
$6.50 an hour
multiply this by ten to find the cost for 10 hours
$6.5 x 10 = $65
she will earn $65 in ten hours.
hope this helps! :D
Ok so the best way to solve this problem is to simplify it as small as possible so first with the given equation 6(x+7)+3x you need to use the distributive property on 6(x+7)
This should get you 6x + 42
Then you have to add everything with like terms (or everything with the variable x) So add together 6x + 3x and that should get you 9x
So now you are left with
9x + 42 which is C
Hope this helps :D
Function A because in one hour it gets up by 4 but in function B it gets up by only 2
