Step-by-step explanation:The time taken by car to pass the truck is 1.125 hours
Solution:
A truck enters a highway driving 60 miles per hour a car
The car enters the highway at the same place 9 minutes later and drive 68 miles per hour in the same direction from the time the car enters the highway
Let us first convert 9 minutes to hours
Let the truck covers 'x' m distance in time 't' hour the car will take [t -(3/20)] hour to cover the same distance 'x'
We know that,
For truck : ----------- eqn 1
For car: ------------ eqn 2
From equations (i) and (ii)
Thus the time taken by car to pass the truck is:
Thus the time taken by car to pass the truck is 1.125 hours

Number of miles that marker shows when passes through town= 160 miles.
Number of miles that marker shows currently to John = 115 miles.
We need to find the distance between town and John's current location.
For the problem, we can clearly see that Town is at 160 miles away but when John passes the marker shows 115 miles.
So, it's just the difference between 160 miles and 115 miles.
In order to find that difference, we need to subtract those two numbers.
160miles - 115miles = 45 miles.
So, we could say the distance between town and John's current location is 45 miles.
He'll be able to make 6 shelves.
Step-by-step explanation:
In order to know haw many shelves he can make we need to take the total amount of material and divide it by the amount of material required for each shelve. We have:
total amount = 83 1/2 inches = 83.5 inches
amount per shelve = 12 3/4 inches = 12.75 inches
amount of shelves = total amount/amount per shelve
amount of shelves = 83.5/12.75 = 6.55 shelves
Since he can't make half shelves he'll be able to make 6 shelves and have left over material.
4.5 hours
30 minutes times 9 shelves equals 270
270 minutes translates into 4 and half hours
x=initial deposit amount.
we have to add to the initial deposit amount the incomes and subtract the withdrawal
x+($75.5+$55.25)-($25.15+$18.65)=$210.85
Now we solve this equation.
x+$130.75-$43.8=$210.85
x+$86.95=$210.85
x=$210.85-$86.95
x=$123.9

Here is a double number line showing that it costs $3 to buy 2 bags of rice:
1. At this rate, how many bags of rice can you buy with $12? ___________
2. Find the cost per bag. _____________
3. How much do 20 bags of rice cost? _____________
Answers
Answer:
1. 8 bags of rice
2. $1.50 per bag
3. $30
Step-by-step explanation:
For #1, you set up the proportion 3 over 2 is equal to 12 over x and solve by cross multiplication. Then, you should get the answer of 8 bags. For #2, you do $3 divided by 2 to get the answer of $1.50. For #3, you use your answer from #2 and do 1.5 times 20 to get $30.
1. The cost of 12 bags of rice is 18 dollars.
2. Per bag of rice cots 1.5 dollars.
3. The cost of 20 bags of rice is 30 dollars.
What is a unitary method?A unitary method is a mathematical technique for determining the value of a single unit then we can derive any no. of units by multiplying it by the single unit.
Given it costs 3 dollars for 2 bags of rice.
We know if we determine the cost of one bag of rice we can find out the cost of any no. bags of rice.
∴ 2 bags of rice cost 3 dollars,
So, 1 bag of rice cots (3/2) dollars = 1.5 dollars.
1. At the rate of 1.5 dollars per bag of rice 12 bags of rice will cost (1.5×12) dollars = 18 dollars.
2. The cost per bag of rice is 1.5 dollars.
3. The cost of 20 bags of rice is (1.5×20) dollars = 30 dollars.

Answers
Answer:
1) -15/32
2) 2/15
3) -203.5
4) -3/2 = -1.5
5) 10/3 = 3 1/3
Step-by-step explanation:
For 1, you just multiply the numerators and denominators together (3 by 5, 4 by 8) and then because it is negative, add the negative sign.
For 2, you multiply again, but because there are 2 negative signs, it becomes positive.
For 3, you divide 81.4 by 0.4, you could also divide 814 by 4.
For 4, you keep change flip, so the equation would become -9/4 (-2 1/4=-9/4) and 3/2 would become 2/3. The equation would be (-9/4 * 2/3). Then, you would get -18/12 which is -3/2.
For 5, you just multiply 4/3 by 5/2 which is 20/6 and because 2 negatives, it becomes positive.
1. -15/32
-3/4 TIMES 5/8. So what you are going to do is multiply the bottom number by the top number and remember that a negative times positive equals negative. -3 times 5 equals -15 so that's the top number. Then, do the bottom number and it's 8 times 4, which is 32.
2. 2/15
So you do the same stuff for the last problem but now for this one so -1 times -2 is positive 2 so that's going to be the top number. Then 5 times 3 is 15.
3. -203.5
(-81.4)/0.4. So what you can do is do long division and get -203.5.
4. -1/5
(-2 1/4)/11/2. So what we can do is put the first fraction into improper fractions. So that would be -9/4 DIVIDED by 11/2. So then you're going to multiply 11/2 by 2 and get 22/4. Now we have -9/4 divided by 22/4.
5. 3 1/3
Switch them to improper fractions. -4/3 times -5/2. This will definitely be a positive because of the fact that it's a negative times a negative. This would equal 20/6 which can be simplified to 3 and 1/3.

2c=12
c= 6 ( 6 chairs per row)

equation version: 5 + 2 = 7
232 + 13 = 245
7 = 245

23/100
5 + 1 = 23/100 + 13
5 + 1 = 6
23/100 + 13 = 1323/100
