Answers
see steps below:
Answer: v = 7
Step-by-step explanation:
1. Distribute
3 (3v - 4) = 51
9v - 12 = 51
2. Add 12 to both sides
9v - 12 = 51
+ 12 + 12
3. Cancel out 12 + 12
51 + 12 = 63
9v = 63
4. Divide 9 on both sides
9v/9 = 63/9
5. Cancel out 9v/9

Reflection
Step-by-step explanation:
A line, called the line of reflection, will allow an image to reflect through it. Every point in a figure is said to mirror the other figure when they are all equally spaced apart from one another. The reflected picture should have the same size and form as the original, but it faces the opposite way. The opposing signs are created from the coordinates. Changes in posture during contemplation may also result in translation. Pre-image and image are terms used to refer to the same thing in this context.
find X. would love the help thank you
Answers
Answer:
120
Step-by-step explanation:
x + the angle = 180 because it makes a line
we know from the picture that the triangle is equilateral so the angle has to be 60
so 180 = x + 60 and solve for x
They are all equal, so you can divide 180/3.
Each angle is 60°.
To find x, you'll see there is a line extending out. That whole line is 180°.
60° + x = 180°
That should give you x = 120°.

g(x)=5x+50 answer please
Answers
The answer to the linear equation g(x) = 5x+50 is plotted on the graph.
What is a linear equation?A linear equation is one in which the variable's maximum power is always one.A one-degree equation is another term for it.A linear equation in one variable takes the conventional form Ax + B = 0. x is a variable, A is a coefficient, and B is constant in this equation.Given equation:
g(x)=5x+50
The equation can also be written as y = 5x+50.
Now, we can replace the value of x for different numbers in the given equation to get the value of y to create the coordinates.
When we put x = 0 in the equation, we get y = 0 + 50 = 50.
Similarly, if we substitute the value of x as 1 in the equation, we get y = 5(1) + 50 = 55.
If we substitute the value of x as 2, y = 5(2) + 50 = 60
If we substitute the value of x as -1 and -2, we get the value of y as,
y = 5(-1) + 50 = 45 and y = 5(-2) + 50 = 40.
These pairs of values satisfy the linear equation and are plotted on the graph given below.

They are willing to pay no more than $40 to go to all of them.
Jones’ Corn Maze has an entry fee that is $4 less than double the amount of Tomilloso’s Pumpkin Patch entrance fee.
King’s Haunted House has an entry fee that is $2 more than Tomilloso’s Pumpkin Patch.
let
x = amount of Tomilloso’s Pumpkin Patch entrance fee
Therefore, the inequality that represent the situation is as follows;
Jones’ Corn Maze an entry fee = 2x - 4
King’s Haunted House entry fee = 2 + x
Therefore,
2x - 4 + 2 + x + x ≤ 40
4x - 2 ≤ 40
add 2 to both sides of the inequality
4x - 2 + 2 ≤ 40 + 2
4x ≤ 42

Let x be the highest price of house that Holly can afford.
Write an equation in x and solve it to calculate the highest price of house that Holly can afford.
Answers
Answer:
321000
Step-by-step explanation:
The highest price of house that Holly can afford is £343350.
What is tax?In mathematics, the tax calculation is related to the selling price and income of taxpayers. It is a charge imposed by the government on the citizens for the collection of funds for public welfare and expenditure activities. There are two types of taxes: direct tax and indirect tax.
Given that, Holly can afford to spend, including Land Transaction Tax, is £327000.
Here, the tax rate is 5% because that is above £250000 and below £400000.
Let x be the highest price of house that Holly can afford.
x= 327000+5% of 327000
x= 327000+5/100 ×327000
x= 327000+0.05×327000
x= £343350
Therefore, the highest price of house that Holly can afford is £343350.

As shown in the number line, The total distance of the racing road is 70 yards.
it is given that the starting location is -35 yards behind the starting line and the ending location of the race court is 35 yards in front of the starting line.
we have to draw a Number line that has -35 and +35 so the origin of that number line is the starting point of the race court.
In the above figure if we are moving forward towards the origin we find that we are moving 35 yards in the number line, after reaching the origin of the number line move forward again 35 yards then we are at the ending location of the racing court.

A rectangle is a parallelogram with four right angles. This property allows it to have two lines of symmetry.
A rhombus is a parallelogram with four equal sides. The number of lines of symmetry of a rhombus depends on whether it is a square or not. If it has four right angles, the rhombus is a square and thus has four lines of symmetry. If not, the rhombus only has two lines of symmetry.

Answers
An equation of line with a slope of 3/4 and containing the point (0,2) is y = (3/4)x + 2
In this question, we have been given
slope (m) = 3/4
and a point (0, 2)
We need to find an equation of a line with a slope of 3/4 and containing the point (0,2)
Using the formula for the slope-point form of equation of line,
y - y1 = m(x - x1)
y - 2 = 3/4(x - 0)
y - 2 = (3/4)x
y = (3/4)x + 2
Therefore, an equation of line with a slope of 3/4 and containing the point (0,2) is y = (3/4)x + 2
