Answer:

32.8

Step-by-step explanation:

We are given the expression:

39/y +5y

We know that y is equal to 5. Therefore, we can substitute 5 in for every y.

39/5 + 5(5)

Solve from left to right according to PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction)

First, divide 39 by 5.

7.8+5(5)

Next, multiply 5 and 5

7.8+25

Finally, add 7.8 and 25

32.8

What is the sum of the angle measures in dodecagon
Alecsey [184]

Dodecagon is a plane figure with 12 sides. To find the sum of angles of a dodecagon, we have to use the formula of sum of angles of a polygon with n sides, which is

S= (n-2)180

For Dodecagon , n=12. Therefore on substituting 12 for n , we will get

S= (12-2)180 =10*180 = 1800 degree .

SO the sum of angle measures of a dodecagon is 1800 degree .

Help cause I haven’t been paying attention in class hehehe
kifflom [539]

Answer:

1) g ≥ 17

2) g > -10

3) g > -1

Step-by-step explanation:

1) 7 (g-19) ≥ -14  divide both sides by 7

g - 19 ≥ -2          add 19 to both sides

∴ g ≥ 17

=======================================

2)   3(7g+17) > -19 + 14g

21g + 51 > -19 + 14g

21g - 14g> -19 - 51

7g > -70

g > -10

========================================

6(-6g+6) > -2(19g-17)

-36g + 36 > -38g + 34

-36g + 38g > 34 - 36

2g > -2

g > -1

========================================
