Answer:
45-40
Step-by-step explanation:
The first interval is 15-19.
The width of this interval is: 19-15=4
The second interval is 30-34.
The width of this interval is: 34-30=4
The third interval is 40-45.
The width of this interval is: 45-40=5
The fourth interval is 45-49.
The width of this interval is: 49-45=4
<h3>Therefore the interval that is not equal to the other three is 45-40</h3>

Answer:
Part A
Add Like terms
6x + 2x + 13 = 3x - 12
8x + 13 = 3x - 12
get x on the left side
5x + 13 = -12
Subtract 13 from both sides
5x = -13 -12
5x = -25
Divide both sides by 5
x = -5

Answer:
£11,000.
Step-by-step explanation:
First, lets figure out how much 1g of gold costs by doing simple division:
£4000 / 200g = £20
1g = £20
Now we can multiply the cost of 1g of gold by 550g
£20 * 550g = £11,000
550g of gold would cost £11,000.
