Answer:

The sum of two numbers is 18.

5 times the first number subtracted from 4/7 of the second number is 14.

First number --> x

Second number --> y

so

x + y = 18 --> x = 18-y

5x - (4/7)y = 14

so

5 (18-y) - (4/7)y = 14

90 - 5y - 4/7 y = 14

-5.57 y = 14-90

y = 13.64

so

x = 18 - 13.64

x = 4.36

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.

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°.

Answer:

y= 3/5x + 3

Step-by-step explanation:

slope= 3/5

y intercept= 3

Answer: [tex]y=\frac{3}{5} x+3[/tex]

Step-by-step explanation:

To find the equation of the graph, we need to know the slope and y-intercept. We can find the slope by using the formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]. Then, we use a point to find the y-intercept. Let's use the points (0,3) and (-5,0).

[tex]m=\frac{0-3}{-5-0} =\frac{-3}{-5} =\frac{3}{5}[/tex]

Now that we know the slope, we can plug in any point to find the y-intercept.

[tex]3=\frac{3}{5} (0)+b[/tex]            [multiply]

[tex]b=3[/tex]

Now, we know the equation is [tex]y=\frac{3}{5} x+3[/tex].

A. 26 miles/ 2 gallons

Step-by-step explanation:

We are trying to find which is the equivalent to the unit rate of 13 miles per gallon, or 13/1

A. 26 miles/2 gallons. Divide both by 2 to get: 13 miles/1 gallon

Correct

B. 2 gallons/26 miles. This is incorrect because 1/13 is not the same as 13/1

Incorrect

C. 39 miles/4 gallons. Divide both by 4 to get: 9.75 miles/1 gallon

Incorrect

D. 4 gallons/39 miles.This is incorrect because 1/13 is not the same as 13/1

8100 visitors in 7th month.

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.

Answer:

780

Step-by-step explanation:

So when you're adding consecutive numbers like this. 1+2+3...+39. You add 39 and 1. This is 40. 2+38 is 40. This is a pattern. Now, we do 40 multiplied by 39 and this will give you the number 1620. After this you would have to divide this product by 2. The answer will soon be 780.

Answer: 45 yards

Step-by-step explanation:

From the question, we are given the information that the plans for a new street show lamp post that are 2.5 inches apart and that the plans use a scale of 0.5 inch = 9 yards,

Since a scale of 0.5 inch = 9 yards is used, the actual distance between the lamp posts will be:

= (2.5inches / 0.5 inches) × 9 yards

= 5 × 9 yards

= 45 yards

The solution to this system of equations is x= 5 and y=2.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

We have Equation:

5x + 2y= 29

x+ 4y= 13

Now, solving above two equation we get

x= 5 and y =2

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

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

18 ) Go...

[tex](3x - 16) + (6x + 7) = 180[/tex]

Collect like terms

[tex]9x - 9 = 180[/tex]

Add sides 9

[tex]9x - 9 + 9 = 180 + 9[/tex]

[tex]9x = 189[/tex]

Divide sides by 9

[tex] \frac{9x}{9} = \frac{189}{9} \\ [/tex]

[tex]x = 21[/tex]

_________________________________

[tex]11y - 32 = 6x + 7[/tex]

[tex]11y - 32 = 6(21) + 7[/tex]

[tex]11y - 32 = 126 + 7[/tex]

[tex]11y - 32 = 133[/tex]

Add sides 32

[tex]11y - 32 + 32 = 133 + 32[/tex]

[tex]11y = 165[/tex]

[tex]8x - 14 = 5x + 34[/tex]

Add sides 14

[tex]8x - 14 + 14 = 5x + 34 + 14 \\ [/tex]

[tex]8x = 5x + 48[/tex]

Subtract sides 5x

[tex] - 5x + 8x = - 5x + 5x + 48[/tex]

[tex]3x = 48[/tex]

Divide sides by 3

[tex] \frac{3x}{3} = \frac{48}{3} \\ [/tex]

[tex]x = 16[/tex]
