Answer:
Yes ,is a reasonable amount. If she has $20 she will have enough to buy the shirt
Step-by-step explanation:
we know that
The total amount is equal to the price of the shirt plus the sales tax
we have that
Multiply 1.048 by the cost of the shirt
Compare
therefore
Yes ,is a reasonable amount. If she has $20 she will have enough to buy the shirt
Answer:
7x - 2
Step-by-step explanation:
let x be the number of bags of chips, then
3x is the number of bags of pretzels ← 3 times the number of bags of chips
3x - 2 is the number of bags of nachos ← 2 less than bags of pretzels
total snacks bought = x + 3x + 3x - 2 = 7x - 2
Cosine = adjacent / hypotenuse
cos (49)= x/27
27 * cos(49) = x
27 * 0.656 = x
x = 17.7
Multiply first equation by 8,
24x + 40y = 352
Multiply second equation by 3,
24x - 21y = -75
Now, subtract second from 1st,
61y = 427
y = 427/61
y = 7
Substitute it in very first equation,
3x + 5(7) = 44
3x = 44 - 35
x = 9 / 3
x =3
In short, Your Answer would be Option D) (3, 7)
Hope this helps!
