52 is the answer to this question
A; b; c; d = first; second; third; fourth shelfa + b + c + d = 250 cmb = 2a + 18c = a - 12d = a + 4in terms of a, plug all equations into originala + (2a + 18) + (a - 12) + (a +4) = 2505a + 10 = 2505a = 240a = 48b = 2(48) + 18b = 96 + 18b = 114 cm/1.14 m
Answer:
$385
Step-by-step explanation:
40 x 7 = 280
1.5 x 7 = 10.50
10.50 x 10 = 105
105 + 280 = 385
Step-by-step explanation:
1. move the decimal to make the numbers whole
0.25 - move to the right 2 times - 25
0.044 - move to the right 3 times - 44
2. Multiply 25 * 44 = 1,100
3. Add decimal
you moved the decimal 6 times in total for both numbers...so move the decimal 6 times starting from right.
