Answer:
the price for one pretzel was $1.75
Step-by-step explanation:
d for drinks
p for pretzel
3d + 3p = 9
3d = 9 -3p
d = 3 - p
replace d = 3 - 9 into 4d + 2p = 8.5
4d + 2p = 8.5
4(3 - p) + 2p = 8.5
12 - 4p + 2p = 8.5
-2p = 8.5 - 12
-2p = -3.5
p = 1.75

Step-by-step explanation:
area of rectangel = 5 × 11
area of rectangle = 55 cm
area of circle = π r²
area of circle = 3,14 × 12 × 12
area of circle = 452,16 cm
area of the shaded region
= 452 - 55
= 297 cm
Round your final answer to the nearest hundredth
= 300 cm
Answer:
Step-by-step explanation:
Define ...
z = 3x+2
Substitute for that expression in the given quadratic:
z^2 +7z -8 = 0 . . . . . . your equivalent quadratic
_____
This equation is easily solved by factoring:
(z +8)(z -1) = 0
z = -8 or +1
Then x can be found from z:
(z -2)/3 = x
(-8 -2)/3 = x = -10/3
(+1 -2)/3 = x = -1/3
