Answer:36 postcards
Step-by-step explanation:
jenny bought 12 post cards
joe bought half of the postcards jenny bought = 12/2 = 6
ruth bought 3 times the postcards joe bought = 3 x 6 = 18
total postcards bought by all = 12 + 6 + 18 = 36 postcards
Answer:
The degree of the given polynomial is 3.
Hope it will help :)
Given that, the length of the garden is 2(x+6)feet and width is 3.5x feet.
So, length : l = 2(x+6) and width = 3.5x.
To find the fence of the garden we need to find the perimeter of the rectangle.
Formula to find the perimeter is:
p = 2l + 2b
= 2*2(x+6) + 2*3.5x
= 4(x+6) + 7x By multiplication.
= 4x + 24 + 7x By distribution property.
= 11x + 24 Combining the like terms.
So, he need to buy 11x + 24 feet fencing.
Hope this helps you!
Answer:
b = 5
Step-by-step explanation:
28.95 + 34b ≤ 200
34.05b ≤ 200 - 28.95
34.05b ≤ 171.05
b ≤ 5.023
b = 5 is the answer
check: 5 * 34.05 + 28.95 = 199.2
if b=6: 6 * 34.05 + 28.95 = 233.25
