Answer:
1 ft = 12 inches
3 ft = 36 inches
36/2 = 18
answer = 1/18
Step-by-step explanation:
Line R
2x + 2y = 18
if we divide by 2 in both side
x + y = 9
Line M
x + y = 9
if x = 1, then y = 8
if x = 2, then y = 7
likewise you can find infinite pair answers for x and y
Answers: The page numbers are 11 and 12
==========================================================
Explanation:
Consecutive integers are ones that follow immediately after another. For example, the set {7,8,9,10} are consecutive.
Let,
- x = first page, some positive whole number
- x+1 = second page, follows immediately after page x
Adding those two said pages will lead to 23
first + second = 23
(x) + (x+1) = 23
2x+1 = 23
2x = 23-1
2x = 22
x = 22/2
x = 11 is the first page
x+1 = 11+1 = 12 is the second page
Check: 11+12 = 23 which confirms the answers.
Answer:
52
Step-by-step explanation:
(7x-2) and (20-3x)/4
when x = 4
{7(4) - 2} × {20 - 3(4)}÷4
(28 - 2)×(20 - 12)÷4
26×8÷4
208÷4
