Answer:
$(159+x)
Step-by-step explanation:
Given
Discount price = $x
Amount Emma paid after discount = $159
Original price = Amount paid + Discount
Original price= $159 + $x
Hence the required expression is $(159+x)
here you gooo
you can just copy this
this is the exact squared root chart
5r + 8 < 63
5r < 63 - 8
5r < 55
r < 55
{r | r < 11}
We have the following equation:
D = m / V
Where,
m: mass
V: volume
D: density.
The volume of the rectangular prism is:
V = (5) * (10) * (8)
V = 400 cm ^ 3
For Lead:
m = D * V
m = (11.36) * (400)
m = 4544 grams
For Iron:
m = D * V
m = (7.87) * (400)
m = 3148 grams
The difference of the masses is:
4544 - 3148 = 1396 grams
Answer:
The mass of the prism made of lead is 1396 grams than the one made of iron
The answert to the a portion is A: 2,3,5,8
