Kallie has $45.50 saved towards a new bike. If the bike costs $184.76 including tax, how much does she have to save each week to be able to buy it in 6 weeks? Kallie starts her solution but does not finish. 184.76 minus 45.50 = 139.26

Which equation would be the second step of this solution?
x = 139.26 divided by 6
x = 6 times 139.26
x = 6 divided by 139.6
x = 6 times 45.50

idk

step-by-step explanation:

delaney would like to make a 5lb nut mixture that is 60% peanuts and 40% almonds.

she has several pounds of peanuts and several pounds of a mixture that is 20% peanuts and 80% almonds.

let 'p' represent the number of pounds of peanuts needed to make the new mixture, and  

let 'm' represent the number of pounds of the 80% almond-20% peanut mixture.

:

p + m = 5

therefore

m = (5-p)

write an equation based on the percent of peanuts

1p + .2m = .6(5)

replace m with (5-p)

p + .2(5-p) = .6(5)

p + 1 - .2p = 3

p - .2p = 3 - 1

.8p = 2

p = 2/.8

p = 2.5 lbs of peanuts required

then

5 - 2.5 = 2.5 lbs of the peanut/almond mixture required

:

a) what is the system that models this situation?

p + m = 5

1p + .2m = .6(5)

i those same problems in math and dont know how to do them

i think it’s c i believe
