Hey there!

22. 8³ means 8*8*8 not8*3. So you would have to multiply 8 three times. 8*8*8= 512. So 8³= 512

23. Like the answer above you would have to multiply 10 six times. 10^6 power is 1,000,000 and now multiply that by 8 and you would get 8,000,000

25. 8+5(4)-3(2)
Multiply and divide left to right, 5(4)= 20 and 3(2)=6
8+20-6
Add and subtract left to right, 8+20= 28
28-6= 22

29.$34
960*2=1920 (bus rentals)
80*10=800 (lunch)
1920+800=2720 (total cost)
2720/80=34 (cost per student)

39. So for 8 months

Height for 8 months = 10 + 3x8 millimeters
Height for 8 months = 10 + 24 millimeters
Height for 8 months = 34 millimeters

For 3 Years.
There are 12 months in 1 year.
For 3 years there are 12 x 3 = 36 months

Plug it into the equation
Height for 36 months = 10 + 3x36
Height for 36 months = 10 + 108
Height for 36 months = 118 millimeters

54. a . It costs $20 for an adult and $13 for a student because for every adult it costs $20 each and for every student, it costs $13 each
B. 20(4)+13(24)
80+312= 392
So The total cost is $392

Hope this helps!

The number of right-handed students in a math class is nine times the number of left-handed students. The total number of studen
nirvana33 [79]
R - Right Handed 
L - Left Handed 

R = 9L ( the number of right handed kids is equal to having 9*number of left handed kids) 
9L + L = 30  ( since total number of people in class is 30) 
10L = 30 
( Divide by 10 both sides )
L = 3 

so... There are 3 Left Handed kids and 27 Right Handed kids ( since R = 9L , R = 9(3) = 27)

Hope this helped!

I will give you brainlest plzzz helppp!!!!
Morgarella [4.7K]

Answer:

329/9, the answer seems wrong but I triple checked because I thought so too. The answer is 100% correct

Step-by-step explanation:

Angle EFG + Angle FGH + Angle GEF = 180 degrees

(2x+1) + (6x+2) + (x + 19) = 180 degrees

9x + 22 = 180 degrees

9x = 158 degrees

x= 158/9

x+19 = Angle GEF

158/9 + 19 = Angle GEF

329/9 =Angle GEF

Double check:

(2x+1) + (6x+2) + (x + 19), x=158/9

2(158/9) + 1 = 325/9

6(158/9) +2 = 322/3

(158/9) +19 = 329/9

325/9 + 322/3 + 329/9 = 180
