Find a variable with equal or opposite coefficients, if equal then subtract the equations but if opposite then add, solve one variable equation left, and then substitute known variable into other equation and solve
Population of England in 2003 = 383 * 130,281 = 49,897,623
In 2008 this is 0.84 * 61,000,000 = 51,240,000
Increase = 51,240,000 - 49,897,623 = 1,342,377
Answer is 1,300,000 to 2 significant figures.
Answer:
X= 24
Step-by-step explanation:
Y was multiplied by 3 to equal 30, so same rules are applied and you multiply 8 by 3
The only ratio there equal to 6:3 is 54:27
Both 54 and 27 are divisible by 9.
54/9 = 6
27/9= 3
Therefore, 54:27=6:3
