@mathstudent55

Answer 3

x is the number of pounds of cashews
y is the pounds of almonds

what is the total weight ? how do you write it ? any idea ?

Answer 4

7x+5y= <30???

Answer 5

>

Answer 6

if we use numbers instead of letters,
for example
2 lbs of cashews and 3 lbs of almonds
how do you write the total ?

Answer 7

2+3=5

Answer 8

yes. and you use the *same idea* when you have letters instead of numbers

can you try to write what is the total pounds if we have x of cashews and y of almonds ?

Answer 9

ok its the first one and second to the last?

Answer 10

we have to work it out i.e. life will be easier for you if you learn the idea.

the first step is to write the total pounds if you have x pounds plus y pounds
can you try to write that using + sign ?

Answer 11

i thought i had it yesyerday someone was helping and got a f

Answer 12

x+y=

Answer 13

7+5

Answer 14

yes (but without the = sign )
x+y is how we write the sum

it's not 7+5 because 7 and 5 are dollars , not pounds.

we have x+y pounds

next, they say
we want less than 6 pounds
we write
x+y 6
and we have to put in < or >
to remember which, we put the "smaller" (or pointy end) next to the smaller side
and the "big" end of > or < next to the big side

here 6 is the bigger number and the weight x+y is the smaller number

Answer 15

>

Answer 16

if you mean
x+y > 6
that has the "big end" of > next to the x+y , which means the weight of the nuts is bigger than 6
is that what we want ?

Answer 17

ok so one answer is the fourth one x+y<6 right?

Answer 18

yes

now we have to do the cost.

Answer 19

ok so the next would be the first answer

Answer 20

or the last one?

Answer 21

x+y is the weight

we figure out the cost by doing cost per pound times number of pounds

Answer 22

7+5>6

Answer 23

@imqwerty

Answer 24

the cost for cashews is 7x
the cost for almonds is 5y

what is the total cost? can you write it with a + sign ?

Answer 25

the total cost is 7x+5y
they want that to be no more than 30, or to say it another way, less than or equal to 30
7x+5y 30
we want the 30 to be bigger than the 7x+5y
(or equal)

Answer 26

7x+5y>30 right?
