No that is an inverse variation, a direct variation must have a y that is directly proportional to x while the picture shows a y that is inversely proportional to x <span />
Step-by-step explanation:
it is 12 because 12 - 7 is 5 the number 4 is the number multiplied by 3
Step One
Find the sum of the fractions for Monday and Tuesday
1/2 + 2/5
The common denominator for these 2 days is 10
1/2: 1*5/(2*5) = 5/10
2/5:2*2/(2*5) = 4/10
Add these two equivalent fractions together.
5/10 + 4/10 = 9/10
The first 2 days resulted in 9/10 of the shed being completed.
Step Two
Find out how much (in terms of fractions) is left of the shed.
Let the whole shed = 1
Let what has been done = 9/10
What remains is 1 - 9/10 = 1/10
Answer: 1/10 of the shed needs to be done
Answer:
6x + -2y or 2y = 4
Step-by-step explanation:
<u>I think</u>
21 - 6 = x
so the answers is 15
21 - 6 = 15
check:
15 + 6 = 21
