Whats Her Errors And Whats The Soulution

Answers

Answer 1

Answer:

she messed up at -17=34x

Step-by-step explanation:

she added 8x to each side but she was actually supposed to subtract

Answer 2

The error is 8(x - 3) + 7 = 2x(13) and -17 = 34x.

4 - 17 = -13, not 13

8x - 17 = 26x

-17 = 26x -8

-17 = 18x ( it should be like this, but this is still wrong because it should -26)

The solution is:

8(x - 3) + 7 = 2x(4 - 17)

8(x - 3) + 7 = 2x(-13)

8x - 24 + 7 = -26x

8x - 17 = -26x

8x + 26x = 17

34x = 17

x = 17/34

x = 1/2

Hope it helps!

Kirk is getting a raise of 5% due to inflation. His normal salary is $56,000 per year. Which of the following calculations gives Kirk's new salary, in dollars? A. 56,000 +5 B. 56,000 + 56,000(0.05) C. 56,000 + 56,000(0.50) D. 56,000 + 56,000(5) E. 56,000(.05)

Answers

Answer:

The answer is B. 56,000 + 56,000(0.05) because 5% or expressed in decimals 0.05 multiplied by the quantity 56,000 gives us 5% of Kirk's normal salary and added to his normal salary will give us his new salary.

(His new salary is 58,800 and 5% of his normal salary is 2,800)

Answers

Answer:

A: 2, -2

Step-by-step explanation:

the first two represent the x axis and the negative two shows the y axis

Answer:

(2,-2)

Step-by-step explanation:

A set of points is (x,y)

The x-axis is the horizontal line and the y-axis is the vertical line.

Do you see how the point S is in line with 2 on the x-axis? This means that the x point is 2.

Now look across to the y-axis, do you see how point S is in line with -2? This means that the y point is -2.

Put both points together using (x,y)

(2,-2)

Find the perimeter of the semicircle below. Use 3.14 for
pi.
1.6 ft

Answers

Answer:

8.2ft

Step-by-step explanation:

Perimeter of a whole circle = 2*pi*r with radius r

Here we have 1.6ft as the radius so the whole circle's perimeter would be

2 * 3.14 * 1.6 = 10.048

We have half the circle so we half this number to 5.024.

Now we have to add the bottom straight line, which is two radii (two lots of 1.6)

5.024 + 1.6  + 1.6 = 8.224 which is rounded to 8.2ft

So you would first Add 7 to both sides. 2x=8+7
Then simply 8+7 to 15 so 2x=15
