How can one fourthx − 3 = one halfx + 8 be set up as a system of equations?
Delvig [45]
<span>The answer is B.

The reason being is that in this option they have set both sides of the equation separately equal to y. Since they are equal to each other, they would both have to be equal to an unknown y. This would look like this.
y = 1/4x - 3
y = 1/2x + 8.

Then to remove the fractions in each, they multiplied by the denominator associated with x. So, you multiply the first equation by 4.
4y = x - 12.
Then they solve for the numerical value at the end.
4y - x = -12.

You can do the same with the second equation.
y = 1/2x + 8
2y = x + 16
2y - x = 16

These are now the two equations above. </span>

A total of ​$24,000 is to be invested in stocks and bonds. If the amount invested in bonds is three times that invested in​ stoc
Ilya [14]

Answer:

  • bonds: $18,000
  • stocks: $6,000

Step-by-step explanation:

You have a total of $24,000 invested in stocks and bonds in the ratio 1 : 3. You want to know the amount invested in each category.

<h3>Ratio</h3>

Recognizing that the total number of ratio units is 1+3 = 4, and that total represents $24,000, we see that each ratio unit represents $24,000/4 = $6,000.

Multiplying the ratio by $6,000, we see the investment amounts are ...

  stocks : bonds = 1 : 3 = $6,000 : $18,000

$6,000 is invested in stocks; $18,000 is invested in bonds.

Toni rides the Ferris wheel shown for 15 revolutions. A photo of a Ferris wheel has the diameter labeled fifty-six feet. Questio
NARA [144]

Answer:

a. 176 feet b. 2640 feet

Step-by-step explanation:

a. Since the diameter of the Ferris wheel is D = 56 feet, the distance Toni travels in one revolution is the circumference of the Ferris wheel, C = πD.

So C = 22/7 × 56 ft = 22 × 8 ft = 176 feet

b. The distance traveled in 15 revolutions is thus D' = 15 × distance of one revolution = 15 × 176 = 2640 feet
