Eventually you want to divide by 60 which means you multiply by the inverse of that which is 1/60
X² + y² = 225
x - 7y = -75
x = 7y - 75
x² + y² = 225
(7y-75)² + y² = 225
(7y - 75)(7y - 75) + y² = 225
49y² - 525y - 525y + 5625 + y² = 225
50y² - 1050y + 5400 = 0
50(y² - 21y + 108) = 0
y² - 21y + 108 ⇒ (y - 12)(y - 9)
x = 7(12) - 75
x = 84 - 75
x = 9 ⇒ (9,12)
x = 7(9) - 75
x = 63 - 75
x = -12 ⇒ (-12,9)
16 divided by 125 is .128
125 plus 75 is 200
.128 multiplied by 200 is 25.6 days
10% of 40 is 4.
1% of 40 = 40/100 = 0.4.
10% of 40 = 10.
Write 10% as a decimal number = 10% = 10/100 = 0.1
Multiply 0.1 by 40 = 0.1 × .40 = 4
Answer:
the answer is x=185
Step-by-step explanation:
x+240=425
-240 -240
x= 185
