Afarmhouse shelters 15 animals. some are buffalo and some are ducks. altogether there are 46 legs. how many of each animal are there?

ducks * legs + buffalo * legs = total legs

x*2 + (15-x) *4 = 46

distribute

2x +60 -4x = 46

-2x +60 = 46

subtract 60 from each side

-2x = -14

divide by -2

x = 7

There are 7 ducks

15-7 =8

there are 8 buffalo

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

for a it would be 24 children.

for b i don't understand the question. is it saying for each individual person they pick 5 reds to 7 greens or is it the whole group. clarify and i hope this can you.
