B. 8.55 km

Step-by-step explanation:

You already have 5 km...

3,400 m is 3.4 km....

So, now we have 8.4 km.

15000 cm is 0.15 km.

0.15 + 8.4 = 8.55

I’m not completely sure, but I would say about 3/5 because of the fact that the X is not directly in the middle, so it can’t be 1/2 but it’s very close to the middle which could make it possible that it is 3/5?

How many kilograms of coffee worth 40/kg must be mixed with coffee worth $11/kg to give 12kg of coffee worth $9.50/kg

Kazeer [188]

Answer:

0.62kg

Step-by-step explanation:

Let

x = 40/kg coffee

y = 11/kg coffee

two equations can be derived from the question

x + y = 12 equation 1

40x + 11y = 114 (9.5 x 12) equation 2

multiply equation 1 by 11

11x + 11y = 132 equation 3

subtract eqn 3 from eqn 2

29x = 18

divide both sides of the equation by 29

x = 0.62kg

Please simplify: −23d+81≤−98d+1

Strike441 [17]

$- 23 d + 81 \leq -98 d + 1$

Subtract 81 from both sides :

$-23 d + 81-81 \leq -98d+1 -81$

$-23d \leq -98d-80$

Add 98d to both sides:

$-23d +98 d \leq -98d-80+98d$

$75d \leq -80$

Divide both sides by 75 :

$\frac{75d}{75} \leq \frac{-80}{75}$

$d \leq =- \frac{16}{15}$

hope this helps!.
