Отвечать:
440 км
Пошаговое объяснение:
Учитывая, что :
Пройденное расстояние за 27/7 часов = 220 км
Расстояние, которое необходимо преодолеть за 54/7 часов, составит x
Следовательно, мы можем настроить перекрестное умножение:
27/7 = 220
54/7 = х
Крест умножить
27/7 х = 220 * 54/7
27x / 7 = 11880/7
3.8571428x = 1697.1428
х = 1697,1428 / 3,8571428
х = 439,99999
x = 440 км
Таким образом, за 54/7 часов будет преодолено расстояние 440 км.

Answer:
2 boxes
Step-by-step explanation:
There are roughly 28 grams in an ounce. So if you have 12 ounces, times 28 by 12, which is 336, so you need 336 grams of raisins. Divide by 170, the number of grams in one box, which would be 1.98 boxes, but you have to round up, so you would need two boxes.
1/2 or 0.5 x 3/4 or 0.75 = 0.375 or 3/8
the rest I dont' understand what you wrote, is it a subtraction or a negative?
Parallel lines will have the same slope
y - y1 = m(x - x1)
slope(m) = 2
origin (0,0)...x1 = 0 and y1 = 0
now we sub
y - 0 = 2(x - 0) <===
