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

What the equation of this graph in slope-intercept form?
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].

The sum of two numbers is 18. 5 times the first number subtracted from 4/7 of the second number is 14. Find the number.
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
What is the solution to this system of equations?
5x + 2y 29
x + 4y= 13
OA.
A. X= 5, y = 3
OB. X= 2, y = 5
OC. x = 5, y = 2
OD. x= 3, y = 2
The solution to this system of equations is x= 5 and y=2.
What is Equation?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

A museum has 6,000 visitors in its first month of operation. The museum staff predicts that the number of visitors will increase by 5% each month. Assuming that this prediction is true, how many visitors does the museum expect on the 7th month of operation?
Multiply 5 by 6000 aka 30,000 then multiply 7 then to 210,000 please give brainliest
8100 visitors in 7th month.
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.

f(x) = 3x + 5
g(x) = 4x^2 – 2

Find f(x) – g(x) – h(x).
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

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.
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

Suppose line segments AB and CD are parallel. What is the measure of angle x?
∠ x = *blank* °
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°.
