Stella [2.4K]4 years ago

Answer:

x = <em>5</em>

Step-by-step explanation:

Add 6 to both sides.

5x - 6 + 6 = 2x + 9 + 6

Simplify

5x = 2x + 15

Subtract 2x from both sides.

5x - 2x = 2x + 15 - 2x

Simplify

3x = 15

Divide both sides by 3.

3x/3 = 15/3

Simplify.

x = <em>5.</em>

Solve the given system, using the substitution method.
alexandr1967 [171]
Y = 3x - 7 . . . . . (1)
6x - 2y = 12 . . . (2)

Putting (1) into (2) gives
6x - 2(3x - 7) = 12
6x - 6x + 14 = 12
14 = 12

Therefore, there is no solution.

Answer:

Step-by-step explanation:

LET ORANGES=X

PEARS ARE 3 TIMES =3X

LET CHILDREN=Y

IF WE GIVE 5 ORANGES PER CHILD WE NEED 5Y ORANGES.SO THIS =X

X=5Y........................I

IF WE GIVE 8 PEARS PER CHILD WE NEED 8Y PERARS...THERE ARE STILL 21 PEARS LEFT OUT AFTER THIS THAT IS

8Y+21=3X....................II

SUBSTITUTING FOR X FROM EQN.I..

8Y+21=3*5Y

15Y-8Y=21

7Y=21

Y=3

X==5Y=5*3=15..

SO CHILDREN =3

ORANGES=15

PEARS=3*15=45

In 2019, Company A purchased a commercial building with 8 retail units for $4,200,000. In 2021, Company A decided to sell this b
Otrada [13]

The change as a percentage is 6.7 %

<h3>How to calculate the percentage change ?</h3>

The price of the building in the year 2021 is $4,200,00

The price of the building in 2021 is $4,500,000

Therefore the percentage change can be calculated as follows

= 4,500,000 - 4,200,000/4,500,000 × 100

= 300,000/4,500,000 × 100

= 0.066 × 100

= 6.7 %

Hence the percentage change is 6.7%
