Answer:
(-78/29, -619/29)
Step-by-step explanation:
Since both equations are equal to y we can set them equal to each other
15x+19 = 1/2x - 20
Subtract 1/2x from each side
15x -1/2x +19 = -20
Subtract 19 from each side
14 1/2 x +19-19 = -20-19
Changing to an improper fraction
29/2 x = -38
Multiply each side by 2/29
x = 2/29 * -38
x = -78/29
Now find y
y = 1/2x - 20
y = 1/2 (-78/29) -20
y = -39/29 - 20
Get a common denominator
=-39/20 - 580/29
= -619/29
-39/29 -580/29
Answer:
hello : 256 words
Step-by-step explanation:
2 minutes and 30 = (2×60)+30=150seconds
4 minutes = 4 ×60 = 240 seconds
150seconds →160 words
240 seconds → x ?
x = (160×240) / 150 = 38400/150= 256 words
Answer: KJ becuase it is the first two like on but put backwards.
Answer:
Principal amount (P) = $10,000
Rate (R) = 1.5%
Time (T) = 4 years
Simple interest, I = P X R X T / 100
= 10000 X 1.5 X 4 /100
= 60000 / 100
= $600
Therefore, Balance = P + I
= 10000 + 600
= $10600
