Answer:

x = 4

Step-by-step explanation:

the dimensions of the small triangle to the large triangle are increasing by multiplying by 5.

5 times 5 equals 25

3 times 5 equals 15

so 4 times 5 equals 20

then, you have to solve the equation:

20 = 3x + 8

subtract 8 from both sides

12 = 3x

divide both sides by 3

12 divided by 3 equals 4

so x = 4

What is the value of x in the solution of the system of equations 3x + 2y = 12 and 5x – 2y = 42
uysha [10]

Answer:

x = 27/4

Step-by-step explanation:

3x + 2y = 12 and 5x – 2y = 42

Add the two equations together to eliminate y

3x + 2y = 12

5x – 2y = 42

-----------------------

8x            = 54

Divide each side by 8

8x /8 = 54/8

x = 27/4

If I told you that Mexico's population was 100,000,000 and that their population growth rate was 3.5%, then what would their pop
Stels [109]

Answer:

The population one year from now would be 103,500,000

Step-by-step explanation:

The current population is 100,000,000

Growth rate of 3.5%.

So the population one year from now is 3.5% of the current population(100,000,000) added to the current population(100,000,000).

3.5% of 100,000,000 is 0.035*100,000,000 = 3,500,000.

Added to 100,000,000

100,000,000 + 3,500,000 = 103,500,000

The population one year from now would be 103,500,000
