PLEASE HELP!!! Jake cleaned up his room. He organized his toys into boxes. He put 7 toys in each of 3 bins.If t represents the total number of toys, write and expression that shows how many toys he put away....PLEASE HELP!!
Answers
7 (3) = x
meaning 7 times 3= 21 toys altogether! :)

A: normally we write ratios in (distance):(time) so
marie=325:20
tamara=255:15
B. proportional means that if you conver to fraction and simplify, they will be equall so
325/20=16.25/
255/15=17/1
they are not equal and therefor NOT proportional
3. so we use slope intercept form which is y=mx+b where m=slope and b=y-intercept
so we find the equation
slope=-4/3
we are given the point (0,16)
the y-intercept is where x=0
in (x,y) form, (0,16), x=0 and y=16
b=16
y=-4/3x+16
the x intercept is where the line crosses the x axis or when y=0 so set y=0 so
0=-4/3x+16
subtract 16 from both sides
-16=-4/3x
multiply both sides by -1 because I don't like negatives
16=4/3x
multiply both sides by 3
48=4x
divide both sides by 4
12=x
solution=(12,0)
it will cross at (12,0)

Final answer:
To determine which load is heavier, oak logs weighing 1 2/3 tons or maple logs weighing 1 7/12 tons, we convert these to improper fractions and find that 44/12 tons (oak logs) is heavier than 19/12 tons (maple logs).
Explanation:
To determine which load weighs more, we must compare 1 2/3 tons of oak logs and 1 7/12 tons of maple logs. First, we need to convert these mixed numbers into improper fractions. For the oak logs, we multiply 3 (the whole number) by 3 (the denominator) and add 2 (the numerator), giving us 11/3 tons. For the maple logs, we multiply 1 by 12 (the denominator) and add 7 (the numerator), giving us 19/12 tons.
To compare, we convert these fractions so they have a common denominator:
11/3 tons is equal to 44/12 tons when multiplied by 4/4.
19/12 tons remains unchanged as it already has the common denominator of 12.
Now we compare 44/12 (oak logs) and 19/12 (maple logs). 44/12 tons is greater than 19/12 tons, so the load of oak logs weighs more than the load of maple logs.
