given s=3x+t/r, rearrange the equation for x, in terms of r,s, and t

Answer:

of course

Step-by-step explanation:

On the surface, it seems easy. Can you think of the integers for x, y, and z so that x³+y³+z³=8? Sure. One answer is x = 1, y = -1, and z = 2. But what about the integers for x, y, and z so that x³+y³+z³=42?

That turned out to be much harder—as in, no one was able to solve for those integers for 65 years until a supercomputer finally came up with the solution to 42. (For the record: x = -80538738812075974, y = 80435758145817515, and z = 12602123297335631. Obviously.)

The CD will earn $459.375 interest in 30 months and the balance at maturity will be $10,959.375.

Here, we are given that Ralph deposited $10,500 in an CD account that pays 1.75% simple interest for 30 months.

Simple interest can be calculated using the following formula-

Simple interest = Principle(P) × Time(t) × Rate(r)/ 100

Here,

P = 10,500

t = 30/12

r = 1.75

Thus,

Simple interest = 10,500 × 30/12 × 1.75/ 100

= 10,500 × 5/2 × 175/ 10000

= 10,500 × 5/2 × 7/ 400

= 26,250 × 7/ 400

= $459.375

Thus, the CD will earn $459.375 interest in 30 months.

Balance on maturity will be-

$10,500+ $459.375 = 10,959.375

Thus, the balance at maturity will be $10,959.375.

Answer:

property of equality that justifies the missing step is Division property of equality

Step-by-step explanation:

We need to Identify the property of equality that justifies the missing step

[tex]28=4x-8\\28+8=4x\\36=4x[/tex]

Now, we divide both sides by 4 using division property of equality as it states that [tex]\frac{a}{c}=\frac{b}{c}[/tex]

[tex]\frac{36}{4}=\frac{4x}{4}\\9=x[/tex]

So, The property of equality that justifies the missing step is Division property of equality

Answer:

C

Step-by-step explanation:

The following are mathematical properties that justifies each step Jeremy made:

✔️Step 1: Given

Jeremy simply stated the given equation.

✔️Step 2: Multiplication Property of Equality

Jeremy multiplied both sides of the equation by 2

✔️Step 3: Subtraction property of equality

4x was subtracted from both sides

✔️Step 4: Subtraction property of equality

1 was subtracted from both sides

✔️Step 5: Division property of equality

Both sides were divided by -7

Answer:

X:1 2 3 4 5 Y:7 11 15 19 23.

Step-by-step explanation:

We just need to put in the values of x into the equation: y = 4x + 3.

x = 1:

y = 4(1) + 3

  = 4 + 3

y = 7

x = 2:

y = 4(2) + 3

  = 8 + 3

y = 11

x = 3:

y = 4(3) + 3

  = 12 + 3

y = 15

x = 4:

y = 4(4) + 3

  = 16 + 3

y = 19

x = 5:

y = 4(5) + 3

  = 20 + 3

y = 23

Marine life is dependent upon the microscopic plant life that exists in the photic zone, a zone that goes to a depth where about 1% of the surface light remains. In some waters with a great deal of sediment, the photic zone may go down only 15 or 20 feet. In some murky harbors, the intensity of light d feet below the surface is given by I=Ioe^-0.26d,Where Io is the intensity of light at the surface. What percentage of the surface light will reach a depth of (A) 5 feet? (B) 10 feet?

Answer:

1.2

Step-by-step explanation:

The value of x = 2, the length of AB is 13 and BC is 8.

A, B and C are collinear with point B between points A and C.

   A___________.__________C

                             B

AC = 21 , AB = 15 -x and BC = 4 + 2x

As the point, B is the mid-point of the line AC

Therefore we get

AC = AB + BC

AC = 2AB = 2BC

Therefore we get

AC = AB + BC

21 = 15 -x + 4 + 2x

21 = 19 + x

x = 2

As AB = 15 - x

Now put the value of x in the equation, by putting the value of x = 2.

AB = 15 - 2

    = 13

BC = 4 + 2x

     = 4 + 2×2

     = 4 + 4

     = 8

Therefore the value of x = 2, and the length of AB = 13 and BC = 8.
