Answer:

x = 40

Step-by-step explanation:

Hello there!

Remember the circumference of a circle in degrees is equal to 360

so all of the arcs added together will equal 360

360 = x + 20 + 3x + 15 + 4x + 5

step 1 combine like terms

1x+3x+4x=8x

20+15+5=40

now we have 360 = 8x + 40

step 2 subtract 40 from each side

360 - 40 = 320

40 - 40 cancels out

now we have 320 = 8x

step 3 divide each side by 8

320/8=40

8x/8=x

we're left with x = 40

11. Write the equation in slope intercept form that has a slope of -23 and passes through the point (-1, 2).

11. y = -23x - 21

You can get this by starting with y = mx + b (slope intercept form). Then put in all the knowns and solve for the b.

2 = -23(-1) + b
2 = 23 + b
-21 = b

Then add that to the end of the equation with m = -23

12. -5

The y-intercept of an equation is always the number added on at the end of an equation. It is also the number with no x attached to it.

13. 8x^9y^6

When you use the law of exponents, you need to make sure the exponent goes to each individual term. When we cube the 2, it becomes 8. When you cube x^3, you get x^3*x^3*x^3 or x^9. And with y^2 you get y^6

Kryger [21]

From the information given,

x represents number of small boxes while y represents number of large boxes.

If each small box can hold 6 books and each large box can hold 10 books, it means that the expression for the number of books that x small boxes and y large boxes can hold is

6x + 10y

If James can pack up to 110 books, it means that the number of books that he can pack is less than or equal to 110. The inequality representing this scenario is

6x + 10y ≤ 110

10y ≤ - 6x + 110

Dividing both sides of the equation by 10, we have

y ≤ - 6x/10 + 110/10

y ≤ - 3x/5 + 11

The graph is shown below

The inequality that represents this sitaution is 6x + 10y ≤ 110

The graph of the inequality wil have solid boundary at y = - 3x/5 + 11

and will be shaded below the line.
