€18 is the answer
If you’ve been given an estimate, use that to determine how much £13.50 would be by cross multiplying
y = 2x - 8 3x - 2y = 13
Answer:
{x,y} = {3,-2}
Step-by-step explanation:
// Solve equation [1] for the variable y
[1] y = 2x - 8
// Plug this in for variable y in equation [2]
[2] 3x - 2•(2x-8) = 13
[2] -x = -3
// Solve equation [2] for the variable x
[2] x = 3
// By now we know this much :
x = 3
y = 2x-8
// Use the x value to solve for y
y = 2(3)-8 = -2
Solution :
{x,y} = {3,-2}
In a college philosophy class during the fall semester, there were 323 students,42% of whom were male and the rest of whom were female. In the springsemester, the same number of females was in the class as in the fall, but there were only 298 total students in the class. In the spring, what percent of students were female?
A. 46%B. 58%C. 63%D. 92%
Using the percentage concept, it is found that the percentage of female students in the spring was of:
C. 63%
What is a percentage?The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:
[tex]P = \frac{a}{b} \times 100\%[/tex]
During the fall semester, 58% of 323 students were female, hence:
0.58 x 323 = 187.
Then, during the spring semester, the same amount out of 298, hence:
[tex]P = \frac{187}{298} \times 100\% = 63\%[/tex]

Answer: Linear
Step-by-step explanation:
the sum of the square of two consecutive positive integers is 85. Write a quadratic equation
Answer:
2x^2 + 2x - 83 = 0
Step-by-step explanation:
Consecutive integers differ by 1
Let the first number be x
The next will be (x+1)
The sum of the squares of these two numbers is 85
so we have;
x^2 + (x + 1)^2 =85
= x^2 + x^2 + 2x + 2 = 85
2x^2 + 2x + 2-85 = 0
2x^2 + 2x - 83 = 0

what is the answer to this equation : 1 = 4 + X
Answer: x is -3
Step-by-step explanation: if 1 is equal to 4, 4 has to be decreased down to 1 so -3 plus positive 4 is 1 so 1=1
How do you find a slope and the Y intercept
How to find slope:
Divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.
The actual formula for this is: (y2 - y1)/(x2 - x1).
How to find Y intercept
To find the y-intercept, plug 0 in for 'x' and solve for 'y'.
Ex. 2x + 3y = 12
So you plug in 0 for x therefore it becomes:
3y = 12
so, the y intercept is 4

Please answer! I’ll make brainliest
Answer:
16 feet
Step-by-step explanation:
We are Given that
We have a 34 foot ladder leaning against a 30 foot buildingWe are asked to find the distance of the bottom ladder from bottom of the building.A ladder leaning against a object makes the ladder slanted so that means 34 is our hypotense.
The building height And distance of the bottom of ladder and building is our legs so our formula we use is
[tex] {30}^{2} + {x}^{2} = {34}^{2} [/tex]
[tex]900 + {x}^{2} = 1156[/tex]
[tex] {x}^{2} = 256[/tex]
[tex]x = 16[/tex]

Write the equation of y-axis.
Answer:
The equation of y-axis is x = 0, since, y-axis is a parallel to itself at a distance 0 from it. Let P (x, y) be any point on the y-axis. Then clearly, for all position of P we shall the same abscissa 0 or, x = 0. Therefore, the equation of y-axis is x = 0.

The pair of figures to the right are similar. The area of one figure is given. Find the area of the other figure to the
nearest whole number.
Area of smaller parallelogram = 15 ft?
Answer:
135ft^2
Step-by-step explanation:
Area of the smaller parallelogram = Base * Height
15 = 3 * height
Height = 15/3
Height = 5ft
Since they are both similar
Height of the big parallelogram = 3(5) = 15ft
Area of the other parallelogram = 9 * 15
Area of the other parallelogram = 135ft^2
