Answers

Answer:

11. x = -16

12. k = 6

13. x = -19

14. x = -6

15. x = -20

16. Combining like terms isn't to be used on this type of problem. I'm sorry, can you guess on this one?

17. x = 19

18. n = -10

19. b = 11

20. n = 4

21. r = -6

22. n = -4

Again super sorry about question 16 :(

Answer:

Step-by-step explanation:

11) -1= x/16

x= -16(because when dividing a negative and positive number the answer is always a negative.

12) 7=1+k

k=7-1

k=6

13) x-6=-25

x=-25+6

x=-19

14) -8x=48

x=48/-8

x= -8

15) x/10=-2

x=10*-2

x=-20

Step-by-step explanation:

[tex]12\:squares\\8\:triangles\\\\Total\:shapes =12+8 =20\\\\Triangles: Total\:shapes\\8 : 20\\\\Cross\:cancel\:common\:factor\:4\\\\2 :5[/tex]

The ratio triangles to total shapes is → 2 : 5.

We have to determine the simplest ratio of triangles to total shapes.

For sweets, you have 10 toffees and 15 chocolates in a jar. Find the ratio of number of toffees to the total number of sweets in the jar.

The ratio of number of toffees to the total number of sweets in a jar is -

[tex]$R \;- > \frac{10}{10+15} = \frac{2}{5}[/tex]

R → 2 : 5

According to the question, we have -

Total number triangles = 8

Total number of Shapes = 12 + 8 = 20

The Ratio of number of Triangles to total number of shapes = [tex]$\frac{8}{20}[/tex] = [tex]$\frac{2}{5}[/tex]

Hence, the ratio triangles to total shapes is → 2 : 5.
