The algebraic expression, in terms of y , for the number of stickers John has is given by 4(y + 2)
How to write algebraic expression?Algebra refers to the system for computation using letters or other symbols to represent numbers, with rules for manipulating these symbols.
Number of stickers Albert has = yNumber of stickers Latika has = y + 2Number of stickers John has = 4(y + 2)The expression for the number of stickers John has = 4(y + 2)
For instance, if y = 3
Number of stickers Latika has = y + 2
= 2 + 2
= 4 stickers
Number of stickers John has = 4(y + 4?2)
= 4(3 + 2)
= 4(5)
= 20 stickers
Therefore, the expression which can be used to represent the number of stickers John has is 4(y + 2)
Complete question:

What is Bodmas fraction?.
Answer: Simplification of Fractions.
Step-by-step explanation:
A vertical flagpole, AB,ha a height of 42m. The point B, C and D lie on level ground, and BCD i a traight line Point C i 24 m from the bae of the flagpole. The angle of elevation of the top of the flagpole from point D i 48 degree
Points C and D are 13.82 meters apart.
What is the point in math?
In mathematics, a point (.) is used to indicate an accurate place in space and serves as its representation. It lacks all three dimensions—length, width, and height. It is hence immeasurable. Uppercase letters are typically used to name points.Given : Flag AB, with point B , C ,D lying on ground.
BD = 24 m . AB = 42 m
To find; CD
In triangle ABD, with angle of elevation from D to top of flag pole is 48 degrees.
Tanθ = perpendicular/base
tan 48° = AB/BD
1.1106 = 42/BD
BD= 42/1.1106 = 37.82 m
From the figure:
BD = BC + CD
37.82 m = 24 m + CD
CD = 37.82 m - 24 m = 13.82 m
Points C and D are 13.82 meters apart.

A bread company makes two types of wheat bread, light whole wheat and regular
whole wheat. A loaf of light whole wheat bread requires 2 cups of flour and 1
egg. A loaf of regular whole wheat bread requires 3 cups of flour and 2 eggs. The
bakery has 90 cups of flour and 80 eggs on hand. The profit on the light bread is
$1 per loaf and on the regular bread is $1.50 per loaf. In order to maximize
profits, how many of each loaf should the bakery make?
By the equations, he should make 70 whole wheat bread that would earn a profit of $105 that is maximum he can earn with the given amount of flour and egg.
What is system of equation?simultaneous equations, system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution. A group of two or more equations that share the same variables is known as a system of equations. A set of values for a variable that simultaneously satisfy each equation is the solution to a system of equations. When there are multiple unknowns and there is sufficient data to set up equations in those unknowns, systems of equations are used to solve applications. In general, we need sufficient information to construct equations in the n unknowns.
Here,
Let x be light whole wheat and y be the regular whole wheat.
given,
A loaf of light whole wheat bread requires 2 cups of flour and 1 egg.
A loaf of regular whole wheat bread requires 3 cups of flour and 2 eggs.
The bakery has 90 cups of flour and 80 eggs on hand.
So the system of equation will be,
2x+3y=90
x+2y=80
multiply the second equation by 2,
2x+4y=160
2x+3y=90
subtract the equations,
y=70
by this,
x=-60
So by this he should make 70 whole wheat bread that will make him earn a profit of,

1. If a truck tire holds 25.0 liters of air at 25.0°C, what will be the volume of air in the tire if the temperature
increases to 30.0 C
Answer:
25.4 L
Step-by-step explanation:
Charles's Law
[tex]\sf \dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}\quad \textsf{(when pressure is constant and temperature is in kelvin)}[/tex]
where:
V₁ = first volume.T₁ = first temperature.V₂ = second volume.T₂ = second temperature.Given:
V₁ = 25 LT₁ = 25.0 °CT₂ = 30.0 °CConvert Celsius to kelvin.
Kelvin = Celsius + 273.15
[tex]\implies \sf T_1= 25 + 273.15 = 298.15 \;K[/tex]
[tex]\implies \sf T_2 = 30 + 273.15 = 303.15\; K[/tex]
Substitute the given values into the formula:
[tex]\implies \sf \dfrac{25}{298.15}=\dfrac{V_2}{303.15}[/tex]
[tex]\implies \sf V_2 =303.15 \cdot \dfrac{25}{298.15}[/tex]
[tex]\implies \sf V_2 =\dfrac{7478.75}{298.15}[/tex]
[tex]\implies \sf V_2 =25.41925205...L[/tex]
Therefore, the volume of air in the tire if the temperature increases to 30.0 °C is 25.4 L (nearest tenth).

What is a geometric sequence?Let a₁ be the first term and r be the common ratio.
Then the nth term of the geometric sequence is given as,
aₙ = a₁ · (r)ⁿ⁻¹
The amount of the first 2 terms of a remarkable grouping is 135 and the amount of the third and fourth terms is 60. Then the equations are given below.
a + ar = 136 ...1
ar² + ar³ = 60
r²(a + ar) = 60 ...2
From equations 1 and 2, then we have
r² x 135 = 60
r² = 60/135
r² = 4/9
r = 2/3
Then the value of 'a' is given as,
a + (2/3)a = 135
a = 81

Sₙ > [a₁ (1 - rⁿ)] / (1 - r)
240 > [81(1 - 0.66ⁿ)] / (1 - 0.66)

A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point.
What does origin mean math?
The origin is the point at which all lines in a coordinate system intersect. When x and y are both equal to zero, the axes intersect. The origin's coordinates are (0, 0).
What is equation?
An equation is a mathematical statement that demonstrates the equality of two mathematical expressions.

The Pythagorean Theorem states that the squares on the hypotenuse (the side across from the right angle) of a right triangle, or, in standard algebraic notation, [tex]a^2 + b^2=c^2[/tex], are equal to the squares on the legs.
If we take any point P(x, y) on the circle, then OP = 5 is the radius of the circle.
But OP is also the hypotenuse of the right-angled triangle OPN, formed when we drop a perpendicular from P to the x-axis.
Now in the right-angled triangle, ON = x and NP = y. Thus, using the theorem of Pythagoras,

Answer:
10 + 0.25x < 25Less than 60 refills makes the Gold Cup a better valueStep-by-step explanation:
Let the number of refills be x.
Then the Silver Cup will cost:
10 + 0.25xThe cost of the Gold Cup is $25.
If we need the Gold Cup a better value, then required inequality is:
10 + 0.25x < 25Solve it for x:
0.25x < 25 - 100.25x < 15x < 15/0.25x < 60Answer:
Inequality = 10 + 0.25x < 25
The value of x = x < 60
Step-by-step explanation:
Now we have to,
→ find inequality used to solve for x.
Then the inequality will be,
→ $10 + 0.25x < $25
→ 10 + 0.25x < 25
Required value of x will be,
→ 10 + 0.25x < 25
→ 0.25x < 25 - 10
→ x < 15/0.25
→ [ x < 60 ]
Hence, the value of x < 60.
