Answer:
$(x - 1425)/3
Step-by-step explanation:
Let total monthly budget be x
Amount spent on mortgage = $1425
Remaining balance after spending on mortgage = x - $1425
Amount spent on recreational activities = one-third of the balance
Expressing amount spent on recreational activities as an equation will give;
Amount spent on recreational activities = 1/3 of x - $1425
= 1/3 × ( x - $1425)
= ( x - $1425)/3
Hence the required equation is;
R = $(x - 1425)/3
R means recreational activities
Answer:
2
Step-by-step explanation:
Answer:the least common denominator is 10 because 5x2 is 10 and then 10x1 is 10 its the least for both of them
Step-by-step explanation:
Answer:
40 bottles of juice
60 bottles of water
Step-by-step explanation:
let w represent water, let j represent juice. set up a system of equations:
w+2j=140
w+j=100
isolate the w by itself on the bottom equation:
w=100-j
solve the top equation by substitution, substituting 100-j for w:
w+2j=140
100-j+2j=140
100+j=140
j=40
this means that they bought 40 bottles of juice.
to find the amount of bottles of water the bought, substitute 40 for j in either of the equations (i did it in the bottom one, because it's easier):
w=100-j
w=100-40
w=60
so, they bought 60 bottles of water.
