Answer:

part A= x=1

part B= -13=-11 and -7=-7 and -2=-2

Step-by-step explanation:

part A

5+x-12=x-7

-7+x=x-7

x=1

part B

5+(-4)-12=-4-7

-1-12=-4-7

-13=-4-7

-13=-11

5+x-12=x-7

5+(-12)=-7

-7=-7

5+x-12=x-7

5+5-12=5-7

10-12=-2

-2=-2

Kevin is 333 years older than Daniel. Two years ago, Kevin was 444 times as old as Daniel.

tia_tia [17]

Answer: the equations are

k = d + 33

k - 2 = 4(d-2)

Step-by-step explanation:

Let the present age of Kevin be represented by k

Let the present age of Daniel be represented by d

Kevin is 33 years older than Daniel. This means that the expression for their current age is

k = d + 33

Two years ago, Kevin was 4 times as old as Daniel. This means that 2 will be subtracted from their present ages to depict two years ago. Therefore, Two years ago for Daniel will be d-2

Two years ago for Kevin will be k - 2

Remember that Kevin was 4 times as old as Daniel two years ago, it becomes

k - 2 = 4(d-2)

Two angles in a triangle measure (2.3x+25)° and (5.8x+11)°. what is the value of x if the two angles are congruent to one anothe

Anton [14]

Answer:

The answer is D. x= 4

Step-by-step explanation:

The angles are congruent so

2.3x +25 = 5.8x + 11

2.3x - 5.8x = 11 - 25

-3.5x = -14

x = 14/3.5

x = 4.
