Answer:
$425
Step-by-step explanation:
x = bench
x - 69 = garden table
x + (x - 69)=781
x + x - 69 =781
2x - 69 = 781
2x -69 +69 = 781 + 69
2x = 850
2x/2 = 850/2
x = 425
Bench = 425
If you would like to solve - 3 * a^2 - b^3 + 3 * c^2 - 2 * b^3, if a = 2, b = -1, c = 3, you can calculate this using the following steps:
a = 2, b = -1, c = 3
- 3 * a^2 - b^3 + 3 * c^2 - 2 * b^3 = - 3 * 2^2 - (-1)^3 + 3 * 3^2 - 2 * (-1)^3 = - 3 * 4 - (-1) + 3 * 9 - 2 * (-1) = - 12 + 1 + 27 + 2 = 18
The correct result would be 18.
Answer:
Step-by-step explanation:
1¾ miles/(2⅓ minutes) = (7/4 miles)/(7/3 minutes) = ¾ mile/minute
21 minutes × ¾ mile/minute = 15.75 miles
60 minutes × ¾ mile/minute = 45 miles
