Consider The System Of Equations 3x + Y = 10 And 6x Y = 17 . What Is The Value Of The X-coordinate Of

Answers

Answer 1

Answer:

x = 3

Step-by-step explanation:

These are simultaneous linear equations hence, we add them because +y and -y will cancel eachother.

3x + y = 10

6x - y = 17

____________

9x        = 27

  x         = 27/9

  x         = 3

So, x- coordinate is 3

Answer 2

Answer: the answer should be x = 3

To find the volume we use an equation:

volume = length x width x height

Since this shape is a cube, you only need to know one side to find the volume since all of the sides are equal.

So all you need to find the volume is to multiply 4(1/2) which I am going to simplify to 4.5, is plug it into the equation.

volume = 4.5 x 4.5 x 4.5

Which will get you an answer of 91.125 inches cubed

Answers

Let X represent the percentage of 40.

A dealer paid $10,000 for a used car at an auction. At the dealership, a salesperson sold the car for
30% more than the auction price. The salesperson receives a commission of 5% of the dealership
price. How much commission did the salesperson receive in dollars?
A. $150
B. $650
C. $3,000
D. $12,350

Answers

Answer:

(1.3×10000)×0.05=650$

Step-by-step explanation:

It was sold for 30% more than at the auction, which means we add 30% which is 0.3 of the price at the auction so 10000 + (30/100)×10000 which equals 13000. Now take 5% which is 0.05 of 13000 to get the final answer

triangle has an area of 230.86 square inches. The height of the triangle is 23.8 inches. What is the length of the base of the triangle?

Answers

19.4 inches

Step-by-step explanation:

Area of the traingle = 230.86 sq. inches

Height of the triangle = 23.8 sq. inches

We have,

Area of the triangle =  1/2bh

where,

b = base of the traingle

h = height of the triangle

Now, substituting the given info we get,

230.86 = 1/2b (23.8)

230.86 × 2/23.8 = b

b = 19.4

So, the base of the triangle is 19.4 inches

What is the simple interest earned on an investment of $12,625 in mutual funds for 12 years at a rate of 4%

Answers

Answer:

Interest earned= $6,060

Step-by-step explanation:

Giving the following formula:

Principal (P)= $12,625

Interest (r)= 4%= 0.04

Period of time (t)= 12 years

To calculate the interest earned after twelve years, we need to use the following formula:

I= P*r*t

I= (12,625*0.04*12)

I= $6,060

Interest earned= $6,060

Answers

B is your answer let me know if I’m wrong

The probability that you lose the next two matches is 0.4. The correct option is B.

What is probability?

Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Probability = Number of favourable outcomes / Number of samples

Given that you play tennis regularly with a friend, and from past experience, you believe that the outcome of each match is independent. For any given match you have a probability of 0.6 of winning.

The probability that you lose the next two matches is calculated as:-

Probability = 1 - 0.6

Probability = 0.4

Therefore, the probability that you lose the next two matches is 0.4. The correct option is B.
