I did ths step by step on my whiteboard and I know my answers are right. Sorry if that sounds cocky.
Can I get brainliest?
Let the less expensive scarf be x
expensive scarf = $3 + x
According To The Question,
x+x+$3=$25
2x+$3=25
2x=22
x=$11
expensive scarf = x + $3 = $11 + $3 = $14
HOPE THIS WILL HELP YOU
Okay so all you are doing is filling out the char to do this you fine the increasing rate or the pattern. so 2*3=6 5*3=15 so the pattern is that you are multiplying every input by 3 so 0*3=0
1*3=3
3*3=9
4*3=12
then to fine the differences you just simply write how much you increased or decreased so every difference for this chart will be +3 hope this helped you have an amazing day!!!!
N = 1 corresponds to day 1
n = 2 corresponds to day 2
...etc etc...
n = 21 corresponds to day 21
Plug in n = 21
a_n = 100 + (n-1)*4
a_21 = 100+(21-1)*4 ... replace every n with 21
a_21 = 100 + 20*4
a_21 = 100+80
a_21 = 180
Answer: C) 180 yards
Answer:

Step-by-step explanation:
1) if the required straight line is 'l', the given point is A(a;b), then the required equation of line can be written in form:

where (x₁;y₁) is other point B, which belongs to the 'l';
2) from the equation it is possible to detect the coordinates of the perpendicular, they are (x₁-a;y₁-b);
3) if the given perpendicular is ax+by=5, then the coordinates of the vector (a;b) are coordinates of the vector, which belongs to the required line 'l', and then: x₁-a=a and y₁-b=b;
4) if to substitute the a=x₁-a and b=y₁-b into the required equation of line 'l', then:

5) finally, the equation is: ay=bx, or y=b/a *x (slope-interception form).
note: the suggested solution is not the only way.
