Answer:
she can buy 3 T-shirts
Step-by-step explanation:
200.00-87.96=112.04
112.04-30-30-30=22.04
Let us say that:
x = is the number of ads that Nadia sold every week
P = payment or amount that she receives every week
So the equations we can formulate for choice A and B are:
choice A: P = 110 x
choice B: P = 150 + 85 x
The amount that she receives for A must be greater than
she receives for choice B, so:
110 x > 150 + 85 x (inequality equation)
Calculate for x:
110 x – 85 x > 150
25 x > 150
x > 6
Therefore Nadia must sell more than 6 ads every week so
that Choice A would be the better choice.
P=Q+20
or equivalently
P-Q=20

Thank you Louli!
Answer: Hope this helps took super long to find and type :)
let : a the dividend
you have : a = 5×247 + R .... R is the remainder
when divided a by 5 : R = 0 , R = 1 , R =2 , R = 3 , R = 4
R = 0 : a = 5×247 + 0 = 1235
R = 1 : a = 5×247 + 1 = 1236
R = 2 : a = 5×247 + 2 = 1237
R = 3 : a = 5×247 + 3 = 1238
R = 4 : a = 5×247 + 4 = 1239
Step-by-step explanation:
The answer is A. Let us assume that A=(2,2), B=(-2,-1) and C=(2,-4). We have to find the length of each side (kindly refer to image uploaded for the formula). Side AB is 5, Side BC is 5, and Side AC is 6. Using the formula of finding the perimeter of the triangle, P=Side AB+Side BC+Side AC, the answer will be 16.
