The value of x is given by 28/13.
Given the product of 14 and x is = 14*x = 14x
According to question, the product is equal to 28 more than x. So,
14x = 28+x
14x-x = 28
13x = 28
x = 28/13
Hence the value of x is 28/13.

Three friends go grocery shopping together, and each buys the same kind of oranges. LaMar buys 2 pounds (lb) and pays $7.00. Enrico buys 5 pounds and pays $17.50. Anna buys 3 pounds and pays $10.50. Identify the graph and unit price that represent the orange costs.
The unit price of the oranges bought by the three friends is $3.50 per pound.
Lamar bought 2 pounds for $7 , unit price = 7 / 2 = $ 3.5 per pound
Enrico bought 5 pounds for $17.50 , unit price = 17.50 / 5 = $ 3.5 per pound
Anna bought 3 pounds for $10.50 , unit price = 10.5/ 2 = $3.5 per pound
Hence we can see that the unit price rate for the oranges is $3.50 .
The average price of a product is calculated by dividing the total sales income by the number of units sold. Managers must supply "similar" units when a single product is given in many variations, such as different bottle sizes.
By weighting different unit selling prices higher by unit sales mix (%) for each single variant, the determination of average pricing is made practicable. We obtain pricing per statistical unit when we employ a standard rather than a genuine range of sizes and product types.

Determine whether the given numbers represent the lengths of sides of a right triangle.15,11,4Do the given numbers represent the lengths of the sides of a right triangle?No or Yes
Answer:
No
Explanation:
To determine if the lengths form the side of a right triangle, use the Pythagorean Theorem:
[tex]\begin{gathered} c^2=a^2+b^2 \\ Where\; c\text{ is the hypotenuse, the longest side} \end{gathered}[/tex]Substitute 15,11 and 4 into the formula:
[tex]\begin{gathered} 15^2=225 \\ 11^2+4^2=121+16=137 \\ \text{Therefore:} \\ 15^2\ne11^2+4^2 \end{gathered}[/tex]Since the Pythagorean Theorem does not hold, the side lengths(15,11,4) do not represent the lengths of the sides of a right triangle.

22 more than a number divided by 4
Answer:
X / 4 + 22

Given the definitions of f(x) and g(x) below, find the value of (gof)(3).
f(x) = 2x² - x - 15
g(x) = -5x +9
Answer:
[tex] \huge{ \boxed{gof(3) = 9}}[/tex]
Step-by-step explanation:
In order to find gof(3), we first have to find gof(x). To find gof(x) substitute the f(x) into g(x). That is, for every x found in g(x) substitute it by f(x).
From the question
[tex]f(x) = 2 {x}^{2} - x - 15 \\ g(x) = - 5x + 9 \\ \\ gof(x) = - 5(2 {x}^{2} - x - 15) + 9 \\ gof(x) = - {10x}^{2} + 5x + 75 + 9 \\ \\ gof(x) = - {10x}^{2} + 5x + 84[/tex]
To find gof(3), substitute the value of x that is 3 into gof(x). For every x found in gof(x), replace it by 3 and solve.
[tex]gof(3) = - 10( {3})^{2} + 5(3) + 84 \\ \quad \: \: \: \: \: = - 10(9) + 15 + 84 \\ \: \: \: = - 90 + 15 + 84 \\ = 9[/tex]

Hi please help me in this onei don't know how to solve itfind the value of x
EXPLANATION
If the measure of ∠2= x+78 and the other ∠=40 degrees, by definition we know that sum of interior angles of a triangle is equal to 180 degrees.
Furthermore, we have two congruent legs, so this is an Isosceles triangle with two congruent angles (with the same measure).
Thus,
180 = 40 + 2* m∠2
Substituting m∠2 by the equation as follows:
180 = 40 + 2(x + 78)
Subtracting -40 to both sides:
180 - 40 = 2(x+78)
Simplifying:
140 = 2(x+78)
Dividing both sides by 2:
140/2 = x + 78
Simplifying:
70 = x + 78
Subtracting -78 to both sides:
70 - 78 = x
Simplifying:
-8 = x
Switching:
x = -8
Answer: The value of x is -8.
can anyone help???????
Answer:
The sum of the angles is 180°.
We already know that one angle is 90°, and the other one is 38.
so: 180-(90+38)=52°
the exterior angle+52°= 180° (beacuse the form a flat angle)
so x=180-52
so: x=128°.
Answer:
128°
Step-by-step explanation:
We know that,
the exterior angle of a triangle is equal to the sum of the interior opposite angles of a triangle.
Accordingly,
38 + 90 = x
128° = x

Mr Kennedy raised beef cattle. The stock tank near the windmill has a diameter of 3 meters. When it is full, the water is 1.5 meters deep. How many cubic meters of water are in the stock tank when it is full use 3.14 for pi.A 7.1 B 10.6 C 42.4 D 14.1
Answer: B 10.6
Explanation:
We would assume that the stock tank is cylindrical. We would calculate the volume by applying the formula,
Volume = πr^h
where
π = 3.14
r is the radius of the cylinder
h is the height of the cylinder
From the information given,
diameter = 3
radius = diameter/2 = 3/2
r = 1.5
h = 1.5
Volume = 3.14 x 1.5^2 x 1.5 = 10.5975 cubic meters
By rounding to the nearest tenth,
Volume = 10.6 cubic meters

h(x) -14 1 -2 -20
2*f(3)-3*g(1)+h(3)=
answer:
-29
step-by-step explanation:
you need a graphing calculator.
so, let's start by setting up a table (for my sake because that text is confusing)
x f(x) g(x) h(x)
-3 12 39 -14
0 0 3 1
1 0 7 -2
3 6 39 -20
okay, that's out of the way. now, your equation is 2 * f(3) - 3 * g(1) + h(3).
for f(3), we look at the chart to see which f(x) value matches x=3.
f(3) = 6
same with g(1) and h(3)
g(1) = 7
h(3) = -20
now, replacing the functions(x) with their numbers is the next step.
2 * 6 - 3 *7 + (-20)
(2*6) - (3*7) - 20
(12) - (21) - 20 = -29
