1/2 + 1/5(1/2) = 1/2 + 1/10 = 5/10 + 1/10 = 6/10....this leaves 4/10 (reduces to 2/5) for his children.
(2/5) / 3 = 2/5 * 1/3 = 2/15 for each child <== A
400 in each childs account.....thats (400 * 3) = 1200 ...
2/5 of what is 1200 =
2/5x = 1200
x = 1200 * 5/2
x = 6000/2
x = 3000 <== B
check...
total pay is 3000
1/2 for bills.....- 1500
1/5(-1500) = -1500/5 = -300 ....for savings
3000 - (1500 + 300) = 3000 - 1800 = 1200...remaining for the children
1200/3 = 400 ...for each child.
so ur answers are :
A. 2/15 in each childs account
B. original paycheck = $ 3000
Answer:
<u>j = 2.5s</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Lemon juice (mL) Sugar (gr)
Batch A 500 200
Batch B 750 300
Batch C 1,500 600
2. Write an equation to describe the relationship between j, the amount of lemon juice in mL, and s, the amount of sugar in g.
Ratio = Amount of lemon juice/Amount of sugar
Ratio = 500/200 = 750/300 = 1,500/600
Ratio = 2.5
Now, we can write the equation, this way:
<u>j = 2.5s</u>
Answer:
A. Carla is on the right track because she is finding the slopes of consecutive sides to check for perpendicular sides.
Step-by-step explanation:
Only adjacent sides can be perpendicular, so Jonah's approach of finding slopes of opposite sides cannot work.
Carla is on the right track; choice A.
First, list all the given information:
*100 miles/week
*25 miles/gallon
*$4/gallon
*weekly expenditure reduced by $5
The easiest approach to use here is the dimensional analysis. Cancel out like units if they appear both in the numerator and denominator side. Solve first the original cost. The solution is as follows:
100 miles/week * 1 gal/25 miles * $4/gal = $16/week
The reduced cost would be:
16 - 5 = (New average miles/week) * 1 gal/25 miles * $4/gal
New average miles/week = 68.75 miles/week
