Can You Help Me Its The One Where It Says To Find The Value Of A And B

Answers

Answer 1

Answer:

2b + 42 = 134 —> Opposite angles

2b= 134 – 42

2b= 92

b= 92/2

b= 46

(2b+42) = 2(46)+42 = 92 +42= 134°

134 + (3a+4) =180

134+3a+4=180

3a+138=180

3a= 180 – 138

3a = 42

a=42/3

a=13

I hope I helped you^_^

Find the solution set of the inequality:

Answers

Answer:

-3 + 8 + 15 + 8 - 15 - 3 + 8 = 18

Step-by-step explanation:

I think this is what you meant, I hope this helps <3

Answer:

We have two inequalities here:

-3x + 8/3 < 15 (dividing both sides by -3)

-3x < 15 - 8/3 (subtracting 8/3 from both sides)

-3x < 37/3

x > -37/9

and

-3x + 8 < 15 (subtracting 8 from both sides)

-3x < 7

x > -7/3

So the solution set for the inequality -3x + 8/3 < 15 is x > -37/9, and the solution set for the inequality -3x + 8 < 15 is x > -7/3.

The combined solution set is the intersection of these two sets, which is x > -7/3. Therefore, the solution set for the original inequality is x > -7/3.

1. $1.23 per pair
A dozen is 12 so you do 12x7=84

Then you do 103.32 divided by 84 which gives you 1.23

2. His error was doing 103.32 divided by 7 because he thought it was only 7 pairs but it’s 7 dozen.

a. What is the correct unit?

Answer: 7 dozen= 12 x 7

                           = 84

      correct price= 103.32 divided by  84

Answers

Answer: 3.2

Step-by-step explanation: Exponentiation: 2 ^ 2 = 4

Multiple: the result of step No. 1 * 1 = 4 * 1 = 4

Multiple: 2 * 5 = 10

Divide: the result of step No. 2 : the result of step No. 3 = 4 : 10 = 0.4 = 2/

5

Exponentiation: 2 ^ 5 = 32

Multiple: the result of step No. 4 * the result of step No. 5 = 2/5* 32 = 2 · 32/5·1 = 64/5

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(64, 5) = 1. In the next intermediate step, the fraction result cannot be further simplified by canceling.

In words - two fifths multiplied by thirty-two = sixty-four fifths.

Multiple: the result of step No. 6 * 1 = 64/

5 * 1 = 64 · 1/5 · 1

= 64/5

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD (64, 5) = 1. In the next intermediate step, the fraction result cannot be further simplified by canceling.

In words - sixty-four fifths multiplied by one = sixty-four fifths.

Exponentiation: 2 ^ 2 = 4

Divide: the result of step No. 7 : the result of step No. 8 = 64/5

: 4 = 64/5

· 1/4

= 64 · 1/5 · 4

= 64/20

= 4 · 16/4 · 5

= 16/5

Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 4/1 is 1/4) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the next intermediate step, , cancel by a common factor of 4 gives 16/5

In words - sixty-four fifths divided by four = sixteen fifths.

Answer:

13. $18.60

14. $15.79

Step-by-step explanation:

13.

Jeff starts off with $46.18

He then gives half of his money to his brother (so divide starting money by 2)

46.18 / 2 = 23.09

He now has $23.09

He then buys two donuts for $0.75 each ( 0.75 * 2 = 1.50 ) and a cup of coffee for $2.99 ( so he spent a total of 4.49 ) so we then subtract 4.49 from 23.09

23.09 - 4.49 = 18.6

He had $18.60 left over

14. 5 friends split a 65.20 bill at a restaurant

65.20 / 5 = 13.04

they also each left a $2.75 tip

13.04 + 2.75 = 15.79

They each payed $15.79

Answer:  Jeff has $18 dollars and 6 cents or $18.6

Step-by-step explanation:

Half of $46.18 is $23.09. Then if he bought two donuts and each donut cost $0.75 then you plus $0.75 + $0.75 = 1.5. You then minus $ 1.5 from your current $23.09 dollars, which will equal $21.59. You have to minus the coffe amount which will is $2.99 . You minus $21.59 - $2.99 =$18.6.
