21 blocks, because if he uses 38 you subtract 17 and you get 21
Answer:
4/3 or 1 1/3
Step-by-step explanation:
So if y = 6, when x = 2/3. Then, x would equal 1 and 1/3, because 12 is twice the amount of 6, so you'd also multiply 2/3 by 2.
(To multiply a whole number by a fraction, first multiply the whole number by the numerator and then divide that by the denominator. For example: 2 × 2 = 4, since you can't really divide 4 by 3 it would stay as is, but you can turn it to a mixed number. 4/3 is the same as 1 whole and an extra 1/3, or in other words 1 1/3).
Hope this helped :)
When you add an integer and a natural number, you always get an integer.
<span> let x = price of 1 shirt before sale
A => 3x * 0.75 = 2.25x
B => 2x + x/2 = 2.5x
C => 3x* 0.90 = 2.7x
2.25x < 2,5x < 2.7x
