Answer:
6.39
Step-by-step explanation:
divide the total cost by the total amount of the item for the unit price:
38.34/6=6.39
Answer:
x ≥ 89
Step-by-step explanation:
Since Jonathan needs at least an 89, his score must be greater than or equal to an 89.
Let X be the first and second number.
X+X = 18
+ X-X = 2
2X = 20 (divide both sides by 2
X = 10
Substitute the values to get the second number
10+X = 18
X = 18 -10
X = 8
Therefore, the numbers are 10 and 8
1. Rationalise the denominator
(20+10i+10i-5)/2^2-i^2
2. Collect like terms
((20-5)+(10i+10i))/2^2-i^2
3. Simplify (20-5)+(10i+10i) to 15+20i
15+20i/2^2-i^2
4. Simplify 2^2 to 4
15+20i/4-i^2
5. Use square rule
15+20i/4-(-1)
6. Simplify brackets
15+20i/4+1
7. Simplify 4+1 to 4
15+20i/5
8. Factor out the common term 5
5(2+4i)/5
9. Cancel 5
3+4i
10. Your final answer
3+4i
