So firstly, subtract both sides by 18b:

12b+53\geq -83

Next, subtract both sides by 53:

12b\geq -136

Next, divide both sides by 12:

b\geq -\frac{136}{12}\\\\-\frac{136}{12}\div \frac{4}{4}=-\frac{34}{3}=-11\frac{1}{3}\\\\b\geq -11\frac{1}{3}

<u>Your final answer is b ≥ -34/3 or b ≥ -11 1/3.</u>

Drag the tiles to the correct boxes to complete the pairs. Match each word problem to its solution. Seven more than 3 times a nu
Luba_88 [7]

Answer: (A) The number is 14

(B) Lily is 16 years old

(C)The number is 35

(D) The wallet cost $20

Step-by-step explanation: (A) Let the number be a. Three times the number is equal to 3 times a, or 3a. Seven more than 3a equals 49, that means

7 + 3a = 49

Subtract 7 from both sides of the equation

3a = 42

Divide both sides of the equation by 3

a = 14

The number is 14

(B) Let Hillary's age be h and Lily's age be l, so if Hillary's age is 3 years greater than Lily's age, then we have

h = 3 + l

Then if Hillary's age is now given as 19, the equation becomes

19 = 3 + l

Subtract 3 from both sides of the equation

16 = l

Lily's age is 16

(C) Let the number be x, and so twice the number becomes 2 times x which is 2x. Twice the number decreased by 20 is 50, becomes

2x - 20 = 50

Add 20 to both sides of the equation

2x = 70

Divide both sides of the equation by 2

x = 35

The number is 35

(D) Let each handbag be represented by b and each wallet be represented by w. The cost of each handbag is 10 more than the wallet, so if the wallet cost w, then the handbag would cost w + 10. This can be expressed as

h = w + 10

If she spent a total of 60 for the 2 handbags, then each handbag would cost 60 ÷ 2 which equals 30 per handbag. Substituting for the known value we now have,

30 = w + 10

Subtract 10 from both sides of the equation

20 = w

The cost of a wallet is $20

What is i^84? a) -i b) i c) -1 d) 1
mariarad [96]

Answer:

D) 1

Step-by-step explanation:

When you start raising i to certain powers, you begin to notice a pattern.

i^1=i \\\\i^2=-1 \\\\i^3=-i \\\\i^4=1 \\\\i^5=i \\\\ i^6=-1 \\\\ i^7=-i \\\\i^8= 1

This cycle repeats forever. Since 84 is a multiple of 4, i^84 must be 1. Hope this helps!
