Need help with the left side
Alenkinab [10]

Use mental math to solve each equation:

1.). - 52 = - 52 + k

Simplify both sides.

- 52 = - 52 + k

Flip Equation:

k - 52 = - 52

Add 52 both sides:

k - 52 + 52 = -52 + 52

k = 0, Answer: K = 0


3.). x - 155 = 15

Add 155 to both sides:

x - 155 + 155 = 15 + 155

x = 170, Answer: 170


5.). 2,000 + y = 9,500

Simplify both sides:

y + 2000 = 9500

Subtract 2000 from both sides:

y + 2000 - 2000 = 9500 - 2000

y = 7500, Answer: 7500 Graph: 7500


7.). 111 + f = 100

Simplify both sides:

f + 111 = 100

Subtract 111 from both sides:

f + 111 - 111 = 100 - 111

f = - 11, Answer: f = - 11




Solve each equations:

9.). m - 17 = - 8

Add 17 to both sides:

m - 17 + 17 = - 8 + 17

m = 9, Answer: m = 9



11.). - 44 + n = 36

Simplify both sides of the equations:

n - 44 = 36

Add 44 to both sides:

n - 44 + 44 = 36 + 44

n = 80, Answer: n = 80



13.). x - 255 = 671

Add 255 to both sides:

x - 255 + 255 = 671 + 255

x = 926, Answer: x = 926



15.). x + 14 = 21

Subtract 14 from both sides:

x + 14 - 14 = 21 - 14

x = 7, Answer: x = 7



17.). - 19 = k + 9

Flip equation:

K + 9 = - 19

Subtract 9 from both sides:

k + 9 - 9 = - 19 - 9

k = - 28, Answer: k = - 28



19.). 36 + n = 75

Simplify both sides of equation:

n + 36 = 75

Subtract 36 from sides:

n + 36 - 36 = 75 - 36

n = 39, Answer: n = 39



21.). 41 + k = 7

Simplify both sides of equation:

k + 41 = 7

Subtract 41 from both sides:

k + 41 - 41 = 7 - 41

k = - 34, Answer: k = - 34




23.). - 88 + z = 0

Simplify both sides of equation:

z - 88 = 0

Add 88 to both sides:

z - 88 + 88 = 0 + 88

z = 88, Answer: z = 88





Hope that helps!!!! :)

Lisha is making headbands using ribbon she would like to make 12 headbands each one requires 15.5 inches of ribbon she estimates
Firlakuza [10]

Answer:

Step-by-step explanation:

Lisha is making headbands using ribbon.

each one requires 15.5 inches of ribbon

For 12 headbands Lisha need to buy ribbon = 15.5 × 12

                                                                         = 186 inches

Therefore, Lisha will need to buy 186 inches ribbon.

160 inches ribbon is not sufficient to make 12 headbands. She will need to buy 186 inches or more.

Suppose that A, B, C, are independent random variables, each being uniformly distributed over (0, 1). (a) What is the joint cumu
Gekata [30.6K]

Answer:

a)  F (A , B,C)(a,b,c) = abc

b) Answer is in derivative

Step-by-step explanation:

Hence area is maximum x=6

For ( a,b,c) ∈ (0,1)

We have that      

F A, B,C (a,b,c) = A≤ a , B≤ b , C≤c

                        =P (A≤a) P (B≤b) P (C≤c)

A , B, C ≈ unit  (0,1) we have that

  P (A≤a) =a

 P (B≤b) =b

   P (C≤c)=c

Thus

F (A , B,C)(a,b,c) = abc

b) Answer is in derivative
