42 square ft because 4 times 3 is 12 and 10 times 3 is 30. 30+12=42
The answer is <span>one halfn − 16
</span>
Let the number be n.
<span>One half of a number is (1/2n)
</span><span>decreased by 16 is (-16)
</span><span>one half of a number decreased by 16 is
1/2n - 16
Or </span><span>one halfn − 16</span>
Answer:
11
Step-by-step explanation:
Let the no. of helmet be x
cost of 1 helmet = $12.00
cost of x helmet = $12.00*x = $12x
Let the no. of tire pumps be y
cost of 1 tire pumps = $8.00
cost of x tire pumps = $8.00*y = $8y
Given that total no. of helmet and pump is 18
thus
x + y = 18
y = 18-x
also given
total money spent is $188
thus
12x+8y = 188
using y = 18 - x
we have
12x + 8(18-x) = 188
=> 12x+ 144 - 8x = 188
=> 4x = 188-144 = 44
=> x = 44/4 = 11
Thus, no of helmet bought by Margo is 11.
Answer:
3
Step-by-step explanation:
9/3
It could be written as 8w the simplified version of the example.
Or you could write it as 2(3w + w) which is 2 time the length and width.
