Answer:
(-2,3)
Step-by-step explanation:
Given data
the system of linear equation is presented as
3x+5y=9-----1
2x+3y=5-----2
solve simultaneously
3x+5y=9-----1 X 2
2x+3y=5-----2 X3
subtracting 2 from 1
6x+10y=18
-6x+9y=15
0x+y=3
y= 3
put y= 3 in 1
3x+5(3)=9-----1
3x+15=9
3x= 9-15
3x= -6
x= -6/3
x= -2
Hence the ordered pair is (-2,3)
Ellie has a gift card to buy a new computer. She says the card’s value is not enough to buy any of the computers shown in the table.
Computer Model Cost
Brand A $324
Brand B $377
Brand C $413
Brand D $391
Let v be the value of the gift card. Drag numbers and symbols to complete an inequality that best describes the value of the gift card.
The lowest price of a computer is Brand A $324
The gift card has to be less than that.
The inequality would be: v < 324

Answer:
4x²y² + 20xy² + 25y²
Step-by-step explanation:
(a + b)² = a² + 2ab + b²
a = 2xy ; b = 5y
(2xy +5y)² = (2xy)² + 2*(2xy) * (5y) +(5y)²
= 2²x²y² + 2* 2* 5 * x*y*y + 5²*y²

Mason used a 30% coupon to buy a new computer. After the discount, the cost of the computer was 728. Determine the original price of the computer. Calculate how much money mason saved by using the coupon.
Answer:
Mason saved $312.00.
Step-by-step explanation:
This is because, if you multiply the original price by 30%/100 or $1040 x 0.3 you get $312.00. So basically, multiply the original price by the discount number over 100 you get your answer.
The percentage is calculated by dividing the required value by the total value and multiplying it by 100.
The original price of the computer is 1040.
The amount saved by Mason using the coupon is 312.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying it by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
We have,
Coupon = 30% off
Cost of the computer after the coupon = 728
This means that the cost of the computer is only 70% since 30% is off.
70% = 728
We know that the original price is 100%.
So,
70% = 728
Multiply 100/70 on both sides.
100/70 x 70% = 100/70 x 728
100% = 1040
The original price of the computer is 1040
The amount saved is:
= 1040 - 728
= 312
Thus,
The original price of the computer is 1040.
The amount saved by Mason using the coupon is 312.

The ratio of the number of fiction books to the number of non-fiction books in a library is 8:5. There are 678 more fiction books than non-fiction books. How many non-fiction books are there in the library?
Answer:
1130 non fiction
Step-by-step explanation:
F=fiction
NF=non fiction
F-678=NF
5F=8NF
so NF=5/8F
substitute:
F-678=5/8F
reduce:
3/8F=678
F=1808
NF=1130
There are 1130 non fiction books in the library.
Given that,
Ratio of fiction books (F) to non fiction books (NF) is 8:5.678 more fiction books in library.We need to find the number of non fiction books.According to the scenario, calculation of data are as follows,
[tex]\frac{F}{NF} = \frac{8}{5}[/tex]
or 5F = 8NF
Now, NF = F-678
By putting the value, we get
5F = 8 ( F - 678)
5F = 8F - 5424
3F = 5424
F = 1808
So, By putting in 1st eq. we get,
5 [tex]\times[/tex] 1808 = 8NF
NF = 9040 [tex]\div[/tex] 8
NF = 1130
