Answer:

x is -2

Step-by-step explanation:

1. write your problem out on a scratch piece of paper

2. distribute your -5 to 6x and that gives you -30x

3. distribute your -5 to your 6 which gives you -30

4. now write down the problem again so that you have 30= -30x - 30

5. add 30 to your 30 on the left of the equals and to the -30 on the right of it

6. now you should have 60 = -30x

7. divide everything by -30

8. finally you should get -2 = x

9. very last flip it so that the x is on the left of the equals sign

2+2X=? when X = 2+5Y when Y = 5*Z^2 when Z = 2

Alchen [17]

Since you know Z = 2, you can plug it into:

Y = 5 · Z²

Y = 5 · (2)²

Y = 5 · 4

Y = 20

Now that you know Y = 20, you can plug it into:

X = 2 + 5Y

X = 2 + 5(20)

X = 2 + 100

X = 102

Now that you have X, plug it into "2+2X=?"

2 + 2x = ?

2 + 2(102) = ?

2 + 204 = ?

206 = ?

Jessica and her sister have a combined age of 47. Jessica is 5 years older than her sister. How old is Jessica

maw [93]

Let the sister be x years old.
Then Jessica is x + 5 years old.
Their ages add to 47.

x + x + 5 = 47

2x + 5 = 47

2x = 42

x = 21

x + 5 = 26

Jessica is 26, and her sister is 21.

The combined land area of the countries A and B is 159159,973 square kilometers. Country A is larger by 473473 square kilometer

lora16 [44]

Answer:

The land area of country A and country B are 80223 sq.km. and 79750 sq.km. respectively

Step-by-step explanation:

Let the area of Country B be x

We are given that Country A is larger by 473 square kilometers.

Area of Country A = x+473

Total area of both countries = x+x+473

Total area of both countries = 2x+473

We are given that The combined land area of the countries A and B is 159,973 square kilometers.

So, $2x+473=159973$

$2x=159973-473$

$x=\frac{159973-473}{2}$

x=79750

Area of Country A = x+473=79750+473=80223 sq.km.

Hence the land area of country A and country B are 80223 sq.km. and 79750 sq.km. respectively
