Answer:
x = 4 , y = 1
Step-by-step explanation:
3x + 2y = 14 → (1)
x + y = 5 → (2)
Multiplying (2) by - 2 and adding to (1) will eliminate the y- term
- 2x - 2y = - 10 → (3)
Add (1) and (3) term by term to eliminate y
x = 4
Substitute x = 4 into (2) and evaluate for y
4 + y = 5 ( subtract 4 from both sides )
y = 1
Answer:
The second number ($1,541.02) is greater
Step-by-step explanation:
In the 100s place of the second number is a 5 and in the first a 4
Even though they have the same 1000s number 500 is larger that 400
4/5n – 1/5 = 2/5n
Add 1/5 to both sides
4/5n = 2/5n + 1/5
Subtract 2/5n from both sides
2/5n = 1/5
Divide both sides by 2/5
n = 1/2
Answer:
A = 2.63
B = 2
Step-by-step explanation:
To find the population density, what we need to do simply is divide the population by the area of the UK
mathematically, that would be;
(6.41 * 10^7)/243,610 = 263.125
To the nearest whole person= 263 people/ square meter
So now we want to write 263 in standard form = 2.63 * 10^2
So this means A = 2.63 and B = 2
