Complete The Table To Show The Steps For Combining Like Terms.
Answer 2

The correct steps are;

7x - 4x + (2 + 1 - 5) (Distributive property)

(2+1 - 5) + (7x - 4x ) (Associative property)

-2 + 3x = 3x - 2 (commutative property)

Given the expression (7-4)x + (2 + 1 - 5)

According to the commutative property A + B = B + A

According to the distributive property A (B+C) = AB + AC

= (7-4)x + (2 + 1 - 5)

= 7x - 4x + (2 + 1 - 5) (Distributive property)

Reordering

= 7x - 4x + (2 + 1- 5)

= (2+1 - 5) + (7x - 4x ) (Associative property)

= -2 + 3x

According to commutative property

-2 + 3x = 3x - 2 (commutative property)

Answers

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.

How do you find an adjacent angle?

Answers

Step-by-step explanation:

 If two angles share one side and both derive from the same corner (vertex) point, then they are adjacent angles.

If two angles share one side and both derive from the same corner (vertex) point, then they are adjacent angles. It's important to remember that adjacent angles must have BOTH a common side and common vertex.

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.

whats the answer to this- 2^(2)*(1)/(2^(5))*2^(5)*(1)/(2^(2)) ?

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.
