Answer:Answer:
w + 4 and 4 + w
Step-by-step explanation:
Given phrase,
w is increased by 4,
That is, w + 4
By the commutative property of addition,
The expression would be,
4 + w
For drawing a model that shows w + 4
Take two boxes in which first shows w and second shows 4 and add them,
Similarly, for showing 4 + w, take first box that shows 4 and second box that shows w then add them.
Step-by-step explanation:
Answer:
Step-by-step explanation:
We have, 120% × x = 36
or,
120
100
× x = 36
Multiplying both sides by 100 and dividing both sides by 120,
we have x = 36 ×
100
120
x = 30
5 and 3 = 8 liters , 5 and 4 = 9 liters, and 3 and 4 = 7 liters.
8 + 7 + 8 + 7 = 30 liters, so he can take the 5 liter bucket with the 3 liter bucket twice, and then use the 3 liter bucket and the 4 liter bucket twice.
= 3 ⋅ 2
= 6 is the rational numbe
