Answer:
(-1, 3)
Step-by-step explanation:
5x + 3y = 4
2x + y = 1 ⇒ y=1-2x
- 5x+3(1-2x)=4
- 5x+3-6x=4
- -x=4-3
- -x=1
- x=-1
- y= 1-2(-1)= 1+2=3

Answer:
difference = 3, first term = 4
Step-by-step explanation:
given, a2 = 7
a9 = 28
wkt, a2 = a + d = 7
<u>a9 = a + 8d</u><u> </u><u>=</u><u> </u><u>28</u>
- 7d = - 21
therefore d = 3
and wkt, d = a2 - a
a = 7 - 3 = 4

Answer:
$23.952, since money is always rounded up $23.96
Step-by-step explanation:
the first step is to get the total value of her purchases, thus we add 16.99 + 12.95 to get 29.94
since she will receive a 20% discount that means that she will be paying 80% of the total value
next we set up the ratio as follows:
portion paid / total = x/29.94 = 80/100
solving the ratio gives you 23.952
