Y=d-3. Y is equal to the cost of the sweaters before the price was raised. D represents the price of the sweaters after the price jump. The three is how much the sweater price was raised by. Say the new price of the sweaters are $29.99 each. You would plug in 29.99 for d. y=29.99-3. The new price of the sweaters would be $26.99 (this is just a sample problem)
1) (15x=-32-14y)-1<span>
2) 9x=-64+14y
</span>
1) -15x=32+14y
-
2) 9x=-64+14y
3) -24x=96
3) x=-4
Substitute x into 1) equation

1) -28=-14y
1) y=2
Answer:
x=-4
y=2
Answer:
w = 
Step-by-step explanation:
The question is 
We can first use distributive property to simplify, the distributive property is 
Thus we have:

<em>Now we combine like terms and simplify to get the final answer for w</em><em>.</em>

Thus, w = 
Answer:
8.66 ft
Step-by-step explanation:
A square is a shape that has an equivalent length and breadth across it’s cross section.
What this means is that measuring the length across the top and bottom will yield the same length value.
Thus, mathematically, let’s call the measured height h
The square of this height gives the area
thus;
h^2 = 75
h = √75
h = 8.660254037844
This is approximately 8.7 to one decimal place
Answer:
84.82 inches squared
Step-by-step explanation:
Volume of a sphere formula
Volume=4/3(pi)r^2
r=4.5
therefore
4/3*pi*(4.5)^2=84.8230016469244 inches squared
round to whatever many decimal places
84.82 inches squared
