If 5x - 2y = 30, x = 2/5y + 6. 5x = 2y + 30. X=2/5y+6.
A) .10 d + .25 q = 7.75
B) d + q = 40
Multiplying B) by -.10
B) -.10d -.10q = -4.0
Then adding this to A)
A) .10 d + .25 q = 7.75
.15q = 3.75
Quarters = 25
Therefore, dimes = 15
***************************************************
Double-Check
A) .10 d + .25 q = 7.75
A) .10 * 15 d + .25 * 25 = 7.75
A) 1.50 + 6.25 = 7.75
Correct!!
Answer:
100%
Step-by-step explanation:
P(=2) = 1/6
P(≠2) = 5/6
P = 1/6 + 5/6 = 6/6 = 1
I get x/13 = 106/9............so 9x = 1378 therefore x = 153.1
