the sum of 2 numbers is 35 and their difference is 15

Answers

Answer 1

Answer:

x = 25,

y = 10

Step-by-step explanation:

Call the larger number "x", and the smaller one "y".

Set up a system, based on the given infomration

x + y = 35

x - y = 15

Solve the system by elimination, in this case, one can just add the two systems to eliminate a variable.

x + y = 35

x - y = 15

x + y + x - y = 15 + 35

Simplify,

2x = 50

Inverse operations,

2x = 50

/2     /2

x = 25

Substitute back in to find y,

x + y = 35

x = 25

25 + y = 35

Inverse operations,

25 + y = 35

-25         -25

y = 10

f(x) = 3x + 5
g(x) = 4x^2 – 2
h(x) = x^2 – 3x + 1

Find f(x) – g(x) – h(x).

Answers

Answer:

f(x) – g(x) – h(x) = -5x^2 + 6x + 6

Step-by-step explanation:

Copy f(x) as is:            f(x) = 3x + 5

Negate g(x):              -g(x) = -4x^2 + 2

Negate h(x):               -h(x) = -x^2 + 3x - 1

Now combine like terms:

f(x) – g(x) – h(x) = -5x^2 + 6x + 6

On Saturday morning 350 concert tickets went on a sale. Every 5 min 25 tickets were sold. Determine whether the number the number of remaining tickets is proportional to time in minutes.

Answers

Answer:

the number of tickets remaining is inversely proportional to the time in minutes:

number of tickets remaining  = total amount of tickets - (25 tickets sold per minute x time in minutes) = 350 - 25T

Step-by-step explanation:

for example:

after 5 minutes, the number of tickets remaining = 350 - (25 x 5) = 225 tickets

after 10 minutes, the number of tickets remaining = 350 - (25 x 10) = 100 tickets

after 14 minutes, the number of tickets remaining = 350 - (25 x 145) = 0 tickets

Answer:

Step-by-step explanation:

1. 14/8 or 1 3/4?
2. -5.65 or -5.6?
3. -6 7/8 or -6.8?
4. -3 11/12 or -3 14/15?

Answers

I have high hopes it’s 1. 14/8 or 1 3/4

Answer:

1. Equal

14/8 = 1.75

1 3/4 = 7/4

7/4 = 1.75

2. -5.6

While if they were positive, 5.65 is bigger, but since they’re negative, it’s opposite.

3. -6.8

-6 7/8 = -55/8

-55/8 = -6.875

-6.875 < -6.8

4. -3 11/12

-3 11/12 = -47/12

-47/12 = -3.912

-3 14/15 = -59/15

What is Unitary Method?

The unitary technique involves first determining the value of a single unit,  followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

given:

Visitor in first month= 6000

If the visitors will increase at the rate of 5% then

Visitors in second month

=6000+  6000 x 5/100

=6000 + 300

=6000

So, the visitors in 7 month

=6000+ 7(300)

=6000 +2100

=8100

Hence, there 8100 visitors in 7th month.

A flat-screen television was marked down by 35 percent, which reduced its price by $115.65. What was the original cost of the television before it was marked down?
$214.78
$330.43
$404.78
$4,047.75

Answers

Answer:

B

Step-by-step explanation:

35% of this price is :

35/100 × x = 0.35x

The price reduces by 0.35x.

This equals to 115.65

Now :

0.35x = 115.65

100/35 × 115.65 = 330.43
