Khloe is thinking of a number that is 2 times the value of Carl's number. Khloe's number is also 2 more than 4 times the value of Carl's number. What is Khloe's number?

Answers

Answer 1

Answer: lets x is Carl's number
Khloe is thinking of a number that is 2 times the value of Carl's number = 2x

Khloe's number is also 2 more than 4 times the value of Carl's number: 4x + 2

4x + 2 = 2x
2x = -2
x = -1

Carl's number = -1
Khloe's number = 2(-1) = -2

double check:

4x + 2 = 4(-1) + 2 = -2

answer: Khloe's number is -2

2.) 4x+13y=40
4x+3y=-40

Answers

$\left\{\begin{array}{ccc}4x+13y=40\n4x+3y=-40&/\cdot(-1)\end{array}\right\n+\left\{\begin{array}{ccc}4x+13y=40\n-4x-3y=40\end{array}\right\n-----------\n.\ \ \ \ \ \ 10y=80\ \ \ \ /:10\n.\ \ \ \ \ \ y=8\n\n4x+3\cdot8=-40\n4x+24=-40\n4x=-40-24\n4x=-64\ \ \ \ /:4\nx=-16\n\nSolution:x=-16\ and\ y=8.$

4x + 13y = 40
4x + 3y = -40
using elimination method
10y = 80
y = 8
substitute y in eq1
4x + 13(8) = 40
4x + 104 = 40
4x = 40 - 104
4x = - 64
x = -16

Answers

To find the surface area of the entire sculpture, you need to add up the surface area of each part of the sculpture. Overall, you see two triangles connected by two rectangles at the top, and the half of a cylinder at the bottom.

To find the area of one of the two triangles, you use the equation A = (1/2)bh, where b = the base of the triangle and h = the height. So, the area of one triangle is:

Ian is another of Josie’s clients. He is 60 years old. What is the MHR for Ian when he is training

Answers

Answer:

166 bpm

Step-by-step explanation:

Ian's age = 60

MHR stands for maximum heart rate. There are two methods of calculating the MHR :

1) MHR = 220-age

2) MHR = 217-(0.85×Age)

Both the methods are easy to solve but the most accurate is the second one, hence we use the second method to calculate MHR of Ian.

MHR = 217-(0.85×Age)

= 217-(0.85×60)

166

Since the MHR is calculated in beats per minute (bpm)

Therefore, MHR of Ian = 166bpm

MHR=190-(age-30)/2
MHR=190-(60-30)/2
MHR=190-(30/2)
MHR=190-15
MHR=175 bpm

b) Divide the previous term by -2
c) Subtract 600 from the previous term
d) Add -200 to the previous term

Answers

As you are given multiple choice, you can use trial and error with each of the answers. You can see that with each number the sign before it is reversed (so it goes even, odd , even , odd etc.) and the numbers are halved each time.
The answer is B) because you are dividing by 2 each time, and changing the sign before the number.

The answer would be b. It is b because if you do 400 divided by -2 is -200 and then you just keep dividing by -2
