Answer:
23
Step-by-step explanation:
You could label "today" as "0."
Park every 2 days: 2, 4, 6, 8, 10, 12, 14, (etc.) days
Library every 5 days: 5, 10, 15, 20 (etc.)
You can see that the smallest number of days that must go by before Ben can do both things on one day is 10.
Answer:
AB = 8
Step-by-step explanation:
AC = 36
AB/BC = 2/7
AB = (2/7)BC
AB + BC = 36
(2/7)BC + BC = 36
(9/7)BC = 36
BC = 36(7/9)
BC = 4*7
BC = 28
AB + BC = 36
AB = 36 - 28
AB = 8
======
Is AB/BC = 2/7?
8/28 = 2/7 YES
Answer:
1000 cm²
Step-by-step explanation:
perimeter = 2 * length + 2 * width
2 * 5x + 2 * 2x = 140
10x + 4x = 140
14x = 140
x = 10
Length: 5x = 5(10) = 50
Width: 2x = 2(10) = 20
area = length * width
area = 50 cm * 20 cm
area = 1000 cm²
