Sally had some stickers. She lost 2/3 of them and gave 1/4 of the remainder to Paul. After that, her brother gave her 120 sticke

Svetradugi [14.3K]

This is the concept of algebra, To get the total number of stickers Sally had in the end we proceed as follows;
Suppose the initial number of stickers was x;
When she lost 2/3 of the tickets the remaining, the number of tickets that she lost was 2/3x.
The remaining number of tickets will be:
x-2/3x=1/3x
The number of tickets she gave to Paul will be given by:
1/3x*1/4
1/12x
After her brother gave her 120 tickets, the new number of tickets was:
1/12x+120
=(x+1440)/12
The ratio of the original number to the number she ended up with is 4:3, therefore;
x/[(x+1440)/12]=4/3
x*12/[x+1140]=4/3
[12x]/[x+1440]=4/3
cross-multiplying the expression we get:
3*12x=4[x+1440]
36x=4x+5760
32x=5760
dividing both sides by 32 we get:
(32x)/32=5760/32
x=180
Therefore the initial number of tickets was 180 tickets

What is the solution set of 2x^2+x=15<br>○3,-5/2<br>○-3,5/2<br>○2,-3/2

kozerog [31]

Rewrite 2x^2+x=15 as <span>2x^2+ x - 15 = 0. Use your favorite method to solve this for x. I prefer synthetic div., so will check out whether or not 2 is a root:

____________
2 / 2 1 -15
4 10
---------------------
2 5 -5 Since there is a non-zero remainder, 2 is NOT a root. Eliminate the 3rd answer choice.

Try -3. If used as a divisor in synth. div., will the remainder be zero or not zero? If zero, then -3 is a solution / root.

And so on.</span>

Grade 5 farm has 85 rows of cabbages.If there are 58 cabbages in each row ,how many cabbages are there in the farm to the neares

ElenaW [278]

The number of cabbages on the farm to the nearest thousand is 5000 based on the given parameters

<h3>How to determine the number of cabbages on the farm to the nearest thousand</h3>

The number of rows is given as:

Number of rows = 85

The number of cabbage on each row is

Number of Cabbage on each row = 58

The number of cabbages on the farm is calculated as:

Farm = Number of rows * Number of Cabbage on each row

Substitute the known values (i.e. Number of rows = 85 and Number of Cabbage on each row = 58) in the above equation

Farm = 85 * 58

Evaluate the product of 85 and 58

Farm = 4930

Approximate the above result (i.e. 4930) to the nearest thousand

Farm = 5000

Based on the given parameters, the number of cabbages on the farm to the nearest thousand is 5000

So, the complete parameters are:

Number of rows = 85

Number of Cabbage on each row = 58

Number of Cabbage in the farm = 5000
