Answer:
d = 10/72
Step-by-step explanation:
c and d vary inversely
c = k/d
Where,
k = constant of proportionality
d = 2/9 when c = 5
c = k/d
5 = k ÷ 2/9
5 = k × 9/2
5 = 9k/2
Cross product
5*2 = 9k
10 = 9k
k = 10/9
c = k/d
c = 10/9 ÷ d
c = 10/9 × 1/d
c = 10/9d
find d when c = 8
c = 10/9d
8 = 10/9d
Cross product
8*9d = 10
72d = 10
d = 10/72
Answer:
so whats the question. ...........
5. y=x+5 6. No solution.
To solve I used the graphing method. When graphing the first and second equation for number 5 I get the same line for both this is a dependent system meaning the solution would be the line itself y=x+5. 6. when simplified and graphed the graphs are y=x+5 and y=x+4. Both lines have the same slope and are perpendicular so they have no solution because they will never intersect.
X+Y=78___1
X-Y=10____2
1+2
X+Y=78
X-Y=10
+_____
2X=88
X=44
Sub X=44 in 1
44+Y=78
Y=34
Therefore the numbers are 34,44
