y = ( 3 * x ) - 2.
This is because the card costs for 3 $ and should be multiplied by the number of total cards she buys in that particular day. So 3 * x.
Now as she has got a 2$ off coupon, whatever the total is she gets 2 dollars off on that price. So we will subtract 2 at that time. FInally all this summed up would be equal to y.
Answer:
the answer is -5< x
Step-by-step explanation:
you you start by subtracting 7 by both sides leaving you with -20<4x. then then divide both sides by 4 leaving you with -5< x
Answer:
24.2
Step-by-step explanation:
c = b·sin(C)/sin(B) = 24.15071
16t -2(2t+5) =14
distribute the parenthesis first:
16t-4t-10 = 14
combine like terms:
12t - 10 = 14
add 10 to both sides:
12t = 24
divide both sides by 12
t = 24/12
t = 2
Answer:
30 I think. The bird house is 45 so minus 15 you get 30
