F = 1/2 J = 2M
J = 4M

M + F + J = $280

M + 2M + 4M = $280
7M = $280

M = $280/7 = $40 

J = 4M = 4x40 = $160
F = 1/2 (160) = $80

40 + 160 + 80 = $280

Mary saved $40
Fred saved $80
John saved $160

Put the following equation of a line into slope-intercept form, simplifying all
muminat

Answer:

y = 3/4 + 7

Step-by-step explanation:

you must put the equation into the form of y = mx + b

add 6x to both sides and put it in front of the 56

8y = 6x + 56

y must be by itself by x does not so we divide everything by 8

y = 6/8x + 7

we must simplify the fraction 6/8

y = 3/4x + 7

Eva is at a sushi restaurant. She ordered 2 pieces of squid for a total of $3.50, 1 piece of eel for $3.25, 3 pieces of tuna for
earnstyle [38]
2 pieces of squid = $3.50 
Therefore 1 piece of squid = $1.75 (3.50÷2)

1 piece of eel = $3.25

3 pieces of tuna = $6.75
Therefore 1 piece of tuna = $2.25 (6.75÷3)

4 pieces of crab = $8.00 
Therefore 1 piece of crab = $2 (8÷4)

Put them in order of price and you get 

$1.75 , $2 , $2.25 , $3.25
squid,crab,tuna,eel
