A t-shirt increased in price by 1/4. After the increase, it was priced at £65. What was the original price of the t-shirt?
Answer:
52
Step-by-step explanation:
Given:
1/4
Price at 65
Solution:
Let x be the original price
Based on the given conditions, formulate: [tex]x[/tex] ×[tex](1+\frac{1}{4} )=65[/tex]
Apply Multiplicative Distribution Law: [tex]x+\frac{x}{4} =65[/tex]
Multiply both sides of the equation by the common denominator: [tex]x[/tex]×[tex]4+\frac{x X4}{4} =65 X 4[/tex]
Reduce the fraction: x×4+x=65×4
Multiply the monomials: 4x+x=65×4
Combine like terms: 5x= 65×4
Calculate the product or quotient: 5x= 260
Divide both sides of the equation by the coefficient of variable: x = [tex]\frac{260}{5}[/tex]
Calculate the product or quotient: x = 52
get the result: x = 52
Answer: x = 52

A class has 40 students. The teacher asks how many students in the class have siblings and finds 3/10 of the students have siblings. How many students have siblings?
Answer:
12 students
Step-by-step explanation:
First, find the percentage of how many students have siblings:
3/10 = 0.3 = 30%
40 * 0.3 = 12
This means that 30% of this class are 12 students. These 12 students have siblings.

Determine the slope and y-intercept of the linear function represented by the following scenario: Brooke and her friends decide to go bowling. The cost for the group is $15 for shoe rentals plus $4.00 per game.
The slope of the given scenario will be 4.
The y - intercept of the given scenario will be 15.
What is Equation of line?
The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The cost for the group is $15 for shoe rentals plus $4.00 per game.
Now,
Let number of games = x
And, Total cost of the bowling's = y
Here, The cost for the group is $15 for shoe rentals plus $4.00 per game.
So, We can formulate;
⇒ y = $4.00x + $15
⇒ y = 4x + 15
Compare with the standard form of equation of line y = mx + c, we get;
⇒ Slope = 4
And, The y - intercept = 15
Thus, The slope of the given scenario will be 4.
The y - intercept of the given scenario will be 15.

The Quadratic equation y=0.5(x-1)(x-n) has an x - intercept at (1,0) and a vertex at (-2,4.5). what is the value of n A -5 B -2 C 2 D 5
Step-by-step explanation:
the point being that a quadratic equation has 2 x-intercepts (or solutions of x for y = 0).
the advantage of this nice form the equation is written in is, that we see immediately both conditions, when y can be 0 : one of the bracket expressions must be 0.
so, the point (1, 0) covers (x-1).
we get the solution for (x-n), when we consider that such a quadratic function is simply a parabola and is symmetric around its vertex point.
the x value of the vertex (-2) tells us, that it is 3 units on the left side of the (1, 0) x-intercept point.
due to the symmetry of the curve the second x-intercept point must be even further to the left with additional 3 units distance in x direction.
so, -2 - 3 = -5
and A is the correct answer option.

Answer:
x= 105°
Step-by-step explanation:
one interior angle of a hexagon is=120°
one interior angle of an octagon is=135° 360-255= 105
The size of the angle between the two regular polygons, marked x, is: 105°.
Interior Angle of a Regular PolygonAn interior angle of a regular polygon = [(n - 2)180]/n.Octagon has 8 sides, while hexagon has 6 sides.Thus,
x° = 360 - sum of one interior angle of the regular octagon and hexagon.
One interior angle of octagon = [(8 - 2)180]/8 = 135°
One interior angle of hexagon= [(6 - 2)180]/6 = 120°
x° = 360° - 135° - 120°
x° = 105°
Therefore, the size of the angle between the two regular polygons, marked x, is: 105°.

7x(x-2y)
(2+1)(+5)
Step-by-step explanation:
7x(x - 2y)
= 7x.(x - 2y)
= 7x² - 14xy
= (2 + 1)(+5)
= (3)(5)
= 3 × 5
= 15
Step-by-step explanation:
1) 7x(x - 2y)
= (7x . x) - (7x . 2y)
= 7x² - 14xy
2) (2 + 1)(+5)
= 3(+5)
= (3 . +5)
= (3 . 5)

Kevin is twice as old as his sister Amy their father is five times as old as Amy if the sum of the ages is 64 how old is Amy
Answer:
8 years old
Step-by-step explanation:
Set Amy's age as x.
Kevin's age will be 2x, since he is two times as old as Amy.
Father's age will be 5x, since he is five times as old as Amy.
x + 2x + 5x = Sum of the ages = 64
x + 2x + 5x = 64
Combine like terms: 8x = 64.
Divide 8 on both sides: x = 8.
Amy's age = 8.
