Answer:
b. x = 11/8, x = 59/72.
Step-by-step explanation:
4|8x - 6| = 5|-8x + 7|
square both sides:
16(64x^2 - 96x + 36) = 25( 64x^2 - 112x + 49)
1600x^2 - 1024x^2 - 2800x + 1536x + 1225 - 576 = 0
576x^2 - 1264x + 649 = 0
x = [1264 +/- √(1264^2 - 4 * 576* 649)] / (2*576)
x = 11/8, x = 59/72.
Answer:Holly drank 12 bottles in a week.
Step-by-step explanation:
First change the fraction 1 2/5 litre into a decimal, by doing this, we can know how many litres are there in 2/5.
So= 1 2/5
= 2 ÷5 = 0.4
= 1 + 0.4 = 1.4 liters
1.4 liters is the amount of water in a bottle.
Next, also change the fraction 2 2/5 litres into a decimal.
So=2 2/5
= 2÷5 = 0.4
= 2 + 0.4 = 2.4 liters
She drinks 2.4 liters a day.
To find how many bottles she drank in 1 week, we must multiply the amount of water she drinks in a day to the days in a week.
So= 1 week= 7 days
= 1 day= 2.4 liters
So= 2.4 × 7 = 16.8
She drinks 16.8 in a week.
To find how much bottles she drank in a week, we must divide the amount of liters she drank in one week to the amount of liters are there in a bottle.
So= 16.8 ÷ 1.4= 12 bottles
Holly drinks 12 bottles in a week.
