X=56+4y
6x-6y=678
x-y=113
x=113+y
113+y= 56+4y
57=3y
y=19
x=132
Answer:
C. 350 miles
Step-by-step explanation:
Daphne wants to drive 3/4 of the distance in the first 2 days. So, her mileage per day should be about (3/4)/2 = 3/8 of the total mileage:
(3/8)(932.4 mi) = 349.65 mi ≈ 350 mi
She should drive about 350 miles on each of the first 2 days.
We have to calculate the total cost of the meal. We know that Adam ( A ) and his dad ( D ) share the cost of the meal in the ratio 2 : 3 and that Adam`s dad pays 52.20 Pounds. So A : D = 2 : 3; A : 52.20 = 2 : 3. Using the cross products, A * 3 = 2 * 52.20; A * 3 = 104.40; A = 104.40 : 3; A = 34.80 Pounds. Finally, A + D = 34.80 + 52.20 = 87.00. Answer: The total cost of the meal is 87 Pounds<span>. </span>

The Mosteller formula is
[/tex]
We know that height is 68 inches and weight 141 pounds
We must remember that 1 inches = 2.54 cm and 1 pound 0.453 kg
This means 68 inches = 172.72 cm and 141 pounds = 63.95
We substitute on the formula
