9.6/0.8=12

Answer:

the answer is 12 units  

Step-by-step explanation:

u get 9.75 an hour and 0.80 for every unit so subtract 9.75 from 19.35 and u get 9.60 now divide that by 0.80 and u  get 12 units

Answer:

b=4.8 or 48/10

Step-by-step explanation:

So first combine like terms

-5b+6+3b=3b-18

-2b+6=3b-18 (-3b from each side)

-5b+6=-18(-6 from each side)

-5b=-24(divide by -5)

b=4.8 or 48/10

Divide each weight on Earth by 6 to find the weight on the moon

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.

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]

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]

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 = 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=>
