Answer:
180
Step-by-step explanation:
subtract 45,000 (the money you already get) from 90,000 and you get 45,000. next divide 45,000 by 250 and get 180 (the amount of units you need to sell in order to make 90k total)
Logan has two aquariums. One aquarium contains 1.3 cubic feet of water and the other contains 1.9 cubic feet of water. The water in the larger aquarium weighs 37.44 pounds more than the water in the smaller aquarium. Write an equation with a variable on both sides to represent the situation. Then find the weight of 1 cubic foot of water.
Answer:
62.4
Step-by-step explanation:
1. 1.3x+37.44=1.9x
2. 1.3x+37.44-1.3x=1.9x-1.3x
0.6x=37.44
3. x=37.44/0.6=62.4
The weight of 1 cubic foot of water is 62.4 lb.
Representing Equation with variable on both sides
Let 'x' pounds be the weight of 1 cubic foot of water.
We know one aquarium contains 1.3 cubic feet of water. So, the weight of 1.3 cubic feet of water = 1.3x
The other aquarium contains 1.9 cubic feet of water. So, the weight of 1.9 cubic feet of water = 1.9x
It is given in the question that the water in the larger aquarium weighs 37.44 pounds more than the water in the smaller aquarium.
The equation would be
1.9x = 1.3x + 37.44
The above equation quality the condition of variable on both sides.
To find out the weight of 1 cubic foot of water, we will solve the above equation to find the value of x.
1.9x = 1.3x + 37.44
1.9x - 1.3x = 37.44
0.6x = 37.44
x = 37.44/0.6
x = 62.4
So, the weight of 1 cubic foot of water is 62.4 lb.

Find x, y, and z such that x³+y³+z³=k, for each k from 1 to 100.
Answer:
x3+y3+z3=k with k is integer from 1 to 100
solution x=0 , y=0 and z=1 and k= 1
For K= 1 , we have the following solutions (x,y,x) = (1,0,0) ; or (0,1,0) ; or (0,0,1) ,
For k =1 also (9,-8,-6) or (9,-6,-8) or (-8,-6,9) or (-8,9,-6) or (-6,-8,9) or (-6,9,8)
And (-1,1,1) or (1,-1,1)
=>(x+y)3−3x2−3xy2+z3=k
=>(x+y+z)3−3(x+y)2.z−3(x+y).z2=k
=>(x+y+z)3−3(x+y)z[(x+y)−3z]=k
lety=αand z=β
=>x3=−α3−β3+k
For k= 2 we have (x,y,z) = (1,1,0) or (1,0,1) or (0,1,1)
Also for (x,y,z) = (7,-6,-5) or (7,-6,-5) or (-6,-5,7) or (-6,7,-5) or (-5,-6,7) or (-5,7,-6)
For k= 3 we have 1 solution : (x,y,z) = (1,1,1)
For k= 10 , we have the solutions (x,y,z) = (1,1,2) or (1,2,1) or (2,1,1)
For k= 9 we have the solutions (x,y,z) = (1,0,2) or (1,2,0) or (0,1,2) or (0,2,1) or (2,0,1) or (2,1,0)
For k= 8 we have (x,y,z) = ( 0,0,2) or (2,0,0) or (0,2,0)
For k= 17 => (x,y,z) = (1,2,2) or (2,1,2) or ( 2,2,1)
For k = 24 we have (x,y,z) = (2,2,2)
For k= 27 => (x,y,z) = (0,0,3) or (3,0,0) or (0,3,0)
for k= 28 => (x,y,z) = (1,0,3) or (1,3,0) or (1,3,0) or (1,0,3) or (3,0,1) or (3,1,0)
For k=29 => (x,y,z) = (1,1,3) or (1,3,1) or (3,1,1)
For k = 35 we have (x,y,z) = (0,2,3) or (0,3,2) or (3,0,2) or (3,2,0) or 2,0,3) or (2,3,0)
For k =36
we have also solution : x=1,y=2andz=3=>
13+23+33=1+8+27=36 with k= 36 , we have the following
we Have : (x, y,z) = (1, 2, 3) ; (3,2,1); (1,3,2) ; (2,1,3) ; (2,3,1), and (3,1,2)
For k= 43 we have (x,y,z) = (2,2,3) or (2,3,2) or (3,2,2)
For k = 44 we have ( 8,-7,-5) or (8,-5,-7) or (-5,-7,8) or ( -5,8,-7) or (-7,-5,8) or (-7,8,-5)
For k =54 => (x,y,z) = (13,-11,-7) ,
for k = 55 => (x,y,z) = (1,3,3) or (3,1,3) or (3,1,1)
and (x,y,z) = (10,-9,-6) or (10,-6,-9) or ( -6,10,-9) or (-6,-9,10) or (-9,10,-6) or (-9,-6,10)
For k = 62 => (x,y,z) = (3,3,2) or (2,3,3) or (3,2,3)
For k =64 => (x,y,z) = (0,0,4) or (0,4,0) or (4,0,0)

For k= 80=> (x,y,z)= (2,2,4) or (2,4,2) or (4,2,2)
For k = 81 => (x,y,z) = (3,3,3)
For k = 90 => (x,y,z) = (11,-9,-6) or (11,-6,-9) or (-9,11,-6) or (-9,-6,11) or (-6,-9,11) or (-6,11,-9)
k = 99 => (x,y,z) = (4,3,2) or (4,2,3) or (2,3,4) or (2,4,3) or ( 3,2,4 ) or (3,4,2)
(x,y,z) = (5,-3,1) or (5,1,-3) or (-3,5,1) or (-3,1,5) or (1,-3,5) or (1,5,-3)
=> 5^3 + (-3)^3 +1 = 125 -27 +1 = 99 => for k = 99
For K = 92
6^3 + (-5)^3 +1 = 216 -125 +1 = 92

Answer:
y=-4
Step-by-step explanation:
Hope this helps :)
Answer:
y = -4
Step-by-step explanation:
Assuming we are solving for y, start by isolating the variable:
-28 = 5y - 8
-20 = 5y (Added 8 on both sides.)
-4 = y (Divided 5 on both sides.)

Half the product of two numbers x and y minus five times a third number z
Answer:
(1/2)x =y-5+3z
Step-by-step explanation:
The expression for Half the product of two numbers x and y minus five times a third number z, [tex]\frac{xy}{2} - 5z[/tex]
What are expressions?An expression is a sentence with at least two numbers or variables having mathematical operation. Maths operations can be addition, subtraction, multiplication, division.
For example, 2x+3
Given that,
A statement, Half the product of two numbers x and y minus five times a third number z
The expression for the given statement = ?
First line- Half the product of two numbers x and y
⇒ [tex]\frac{xy}{2}[/tex]
Second line- five times a third number z
⇒ 5z
Third operation-
Minus both the expressions
⇒ [tex]\frac{xy}{2} - 5z[/tex]
Hence, the expression is [tex]\frac{xy}{2} - 5z[/tex]
