Find x. Give reasons to justify your solution.

Answers

Answer:

x = 28

Step-by-step explanation:

Okay COB is vertical to AOB, so we know they equal the same. Right the equation this way.

3x + x + x + 12 = 152 (collect like terms)

5x + 12 = 152 (subtract 12 on each side)

5x = 140 (divide by 5 on each side)

x = 28

(PLUG IN)

3(28) + (28) + (28) + 12 = 152

84 + 28 + 28 + 12 = 152

152 = 152

Ms. Howard wrote a test. Part A had true/false questions, each worth points. Part B had multiple choice questions, each worth points. She made the number of points for Part A equal the number of points for Part B. It was the least number of points for which this was possible.

Answers

Full question attached

Answer and explanation:

Since x = number of true or false questions correct

And y = number of multiple choice questions correct

And each question for x =2 points

each question for y=3 points

since she then needs a total score of more than 93 to pass, we add up total correct questions and

Inequality equation = 2x +3y >93

(3) An estate was to be divided among five people. The first person received 1/8 of the estate. The next two people each received 1/5 of the estate. The fourth person received 1/10 of the estate. What fractional part of the estate did the last person receive?

Answers

Answer:

3/8

Step-by-step explanation:

An estate has to be divided among the 5 persons.

Given that the 1st person received 1/8 of the estate,

the 2nd person received 1/5 of the estate,

the 3rd person received 1/5 of the estate,

and the 4th person received 1/10 of the estate.

Let the 5th person received the x part of the estate.

The sum of all the fractional parts of one estate equals to 1, so

[tex]\frac 1 8+\frac 1 5+\frac 1 5+\frac 1 {10}+x=1[/tex]

[tex]\Rightarrow \frac 5 8 +x =1[/tex]

[tex]\Rightarrow x =1-\frac 5 8 =\frac 3 8.[/tex]

Hence, the last person received 3/8  of the estate.

Dom has $90,000 that he wishes to invest now in order to use the accumulation for purchasing a retirement annuity in five years. After consulting with his financial advisor, he has been offered four types of fixed-income investments, labeled as investments A, B, C, and D. Investments A and B are available at the beginning of each of the next five years (call them years 15). Each dollar invested in A at the beginning of a year returns $1.20 (a profit of $0.20) two years later, in time for immediate reinvestment.
