How do you solve 8x-43?

A fort had enough food for 80 soldiers for 60 days .How long would the food last if 20 more soliders join after 15 days ?

Answer:

The food would last 51 days

Step-by-step explanation:

After 15 days are over, you could say that the 16th day would be as follows -

80 soldiers, food finished in 60 - 15 = 45 days.

If 20 more soldiers arrive, there would be a total of 100 soldiers, so if 80 soldiers can finish their food in 45 days - 1 soldier can finish = 45 * 80. Respectively, 100 soldiers can consume their food in ( 45 * 80 ) / 100 = 36 days.

As 15 days are already over, adding 36 more days = 51 days

The food would last 51 days if 20 more soldiers join after 15 days

There are several possible ways to answer this question, but I hope that explanation helps!

Luis Nunez begins walking at a rate of 8 mph. Forty-five minutes after he leaves, his wife, Kristin, realizes that Luis has fo

Aleksandr [31]

Answer:

a). 18 minutes

b). 8.4 miles

Step-by-step explanation:

a). Let Luis meet Kristina after the time = h hours

So the distance traveled by Luis in h hours = Speed × time

= 8×h

= 8h miles

If Kristin started after 45 minutes of $\frac{45}{60}$ hours then the distance traveled by her

= Speed × time

= $28\times (h-\frac{45}{60})$ miles

Since after h hours distances traveled by Luis and Kristin are same so,

$28(h-\frac{45}{60})=8h$

28h - 8h = $\frac{28\times 45}{60}$

20h = 21

h = 1.05 hours

So the time taken by Kristin = (h - 0.75)

= 1.05 - 0.75

= 0.30 hours ≈ 18 minutes

b). Distance traveled by Luis before Kristin catches Luis = 8×1.05

= 8.4 miles

hram777 [196]

Answer:

J

Step-by-step explanation:

h = 1.32t + 1.56

Replace t with 4 (days):

h = 1.32(4) + 1.56

Multiply:

h=5.28 + 1.56

Add:

h=6.84

The correct choice is J
