Answer:
Kabuls = 7.5
Carumpts= 0.85
Step-by-step explanation:
Let x represent the price of kabuls
Let y represent the price of carumpts
8x + 2y= 61.70......equation 1
3x + 10y= 31.........equation 2
Multiply equation 1 by 3 and equation 2 by 8
24x + 6y= 185.1
24x + 80y= 248
-74y = -62.9
y= 62.9/74
y= 0.85
Substitute 0.85 for y in equation 1
8x + 2(0.85) = 61.70
8x + 1.7= 61.70
8x = 61.70-1.7
8x = 60
x= 60/8
x= 7.5
Hence the dollar value for kabuls is 7.5 and carumpts is 0.85
Answer:
Step-by-step explanation:
Translate the verbal statements into a system of linear equations: Fatima invested a total of $1000 in two simple-interest bank accounts. One account paid 5% annual interest; the other paid 6% annual interest. The total amount of interest she earned after 1 year was $56
Simple interest formula =
I = PRT
We are to find the Amount = Principal invested
For Account 1
I1 = P × 5% × 1
= 0.05P
Account 2
I2 = P × 6% × 1
= 0.06P
Therefore:
0.05P + 0.06P = $56
Answer:
Rule : x subtracted by 12 = y , first ? = 6 (6,-6) , second ? = -22 (-10,-22)
