only 2,4
only 3,9
both 2,4 and 3,9
neither

Answers

Answer 1

Answer:

It is only 3,9.

Step-by-step explanation:

You need to substitute each pair into the equation to find if both side have the same answer, 3,9 is the correct answer because both sides are equal:

2(9) = 7(3)-3

18= 18

The answer is (3,9).

Suppose line segments AB and CD are parallel. What is the measure of angle x?




∠ x = *blank* °

Answers

Answer:

x=75

Step-by-step explanation:

54+51+x=180

105+x=180

x=75

The value of the angle will be equal to x=75.

What is the supplementary angle?

Angles that add up to 180 degrees are referred to as supplementary angles. For instance, angle 130° and angle 50° are complementary angles since the sum of these two angles is 180°. The sum of complementary angles is 90 degrees.

Given that the two angles are 54 and 51 and the remaining angle is x. The value of the unknown angle is calculated by applying the supplementary angle property.

54 + 51 + x = 180

105+ x = 180

x = 75

Hence, the unknown angle is 75°.

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

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

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

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.

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.

-6 7/8 = -55/8

-55/8 = -6.875

-6.875 < -6.8
