200+50+4=254 is the answer
Answer:
3,13,16
Step-by-step explanation:
<span>To find the cost of one roll of
tape, we divide the given price by 2 because the given price is for
twice the number of rolls that we want.
$1.28/2 = $0.64
----------------
To find the cost of two note pads, we first divide the given price by 3 because we want to know how much one note pad costs.
$0.87/3 = $0.29
Each note pad is 29 cents. Since we want to note pads, we double this amount.
$0.29*2 = $0.58
----------------
One highlighter costs $1.59. We want two of them, so we double this amount.
$1.59*2 = $3.18
----------------
We want two boxes of ink catridges, and we are told that two boxes cost $1.98.
----------------
Let's total the amounts:
$0.64 + $0.58 + $3.18 + $1.98 = $6.38
We would pay $6.38 for these seven items.</span>
Answer: I got it to you fast no flash
The first given equation is:
j + k = 3
This can be rewritten as:
j = 3 - k .................> I
The second given equation is:
j - k = 7 ............> II
Substitute with I in II and solve as follows:
j - k = 7
(3-k) - k = 7
3 - 2k = 7
-2k = 7-3 = 4
k = 4/-2
k = -2
Substitute with k in I to get the value of J as follows:
j = 3 - k
j = 3 - (-2) = 3+2
j = 5
Based on the above, the solution is (5,-2)
