Step-by-step explanation:
Solve the following equation for y: ax +by = c
Answer:
[tex]y = \frac{c-ax}{b}[/tex]
Step-by-step explanation:
ax + by = c
subtract ax from both sides
ax + by = c
-ax -ax
=
by = c- ax
divide b on both sides
[tex]\frac{by}{b}[/tex] = [tex]\frac{c- ax}{b}[/tex]
=
[tex]y = \frac{c-ax}{b}[/tex]
Mr Chan bought 20 computers and 25 printers for $30 000. Each computer costs $1250. At a promotion sale, Mr Chan sold each computer at $1700 with a free printer. The selling price of each printer when sold separately was $250.
Find the cost price of each printer.
Answer:
$200.
Step-by-step explanation:
Each computer costed $1,250.
Mr. Chan bought 20 computers.
20 × $1,250 = $25,000
$25,000 out of the $30,000 was spent on computers. That leaves $5,000. Which means $5,000 was spent on the printers.
$5,000 ÷ 25 = $200
(25 = amount of printers.)
So each printer was $200.

d= 10/7
Step-by-step explanation:
Basically what you do is 12/6 and 10/7 for d, because it is the greatest and least on both sides. You do the same for b so it would be 10-7=3 and 12-6=6

stadium already has 250 people in it at noon.If 35 people per minute enter the stadium,how many are in the stadium at 1:30 p.m. when a concert is supposed to begin?
Answer:
3,400 people
Step-by-step explanation:
First, find how many minutes are between noon and 1:30 pm
This is an hour and 30 minutes, so it will be 90 minutes
Then, multiply 90 by 35, since 35 people enter per minute
90(35)
= 3150
Then, add the 250 people that were already in it
3150 + 250
= 3400
So, there will be 3,400 people in the stadium
Answer:
3400
Step-by-step explanation:
250+35m=noon

Step-by-step explanation:
2 hundred and 16 is in word form
Since 200 can be written as a sum of 2 100's, hence there are two hundred in the expression given,
Given the expression 200 + 10 + 6
Each term can be written in words as shown:
200 is two hundred
200 = 100 + 100
Since 200 can be written as a sum of 2 100's, hence there two hundred in the expression given,

the volume of a bucket of water is 864 cubic inches. how many buckets are needed to fill a 7 cubic foot tank?
Answer:
We have the relation:
1ft = 12 inches.
Then, if we cube both sides, we have:
(1ft)^3 = (12 in)^3
1ft^3 = 288 in^3.
Now we know that:
The bucket is 864 in^3
The tank is 7 ft^3.
knowing that 1 ft^3 = 288in^3
Then 7 ft^3 is seven times that:
7ft^3 = 7*(1ft^3) = 7*(288in^3) = 2016 in^3
Now the number of buckets needed to completely fill the tank is:
N = (2016 in^3)/(864in^3) = 2.33
So you need 2.33 buckets, or we can round it up to 3 buckets, where the third bucket will have some water inside it when the tank is completely filled.
