Wilbur and Mike are selling fruit for a school fundraiser. Customers can buy small boxes of grapefruit and large boxes of grapefruit. Wilbur sold 3 small boxes of grapefruit
and 14 large boxes of grapefruit for a total of $306. Mike sold 7 small boxes of grapefruit and 7 large boxes of grapefruit for a total of $252. What is the cost each of one
small box of grapefruit and one large box of grapefru
Answer:
both size boxes are $18 each
Step-by-step explanation:
Let x and y represent the costs of the small and large boxes, respectively. Then the two sales are ...
3x +14y = 306
7x +7y = 252
Doubling the second equation and subtracting the first, we have ...
2(7x +7y) -(3x +14y) = 2(252) -(306)
11x = 198
x = 18
y = 252/7 -x = 36 -18 = 18
A small box costs $18, as does a large box.
Answer:
both size boxes are $18 each
Step-by-step explanation:
Let x and y represent the costs of the small and large boxes, respectively. Then the two sales are ...
3x +14y = 306
7x +7y = 252
Doubling the second equation and subtracting the first, we have ...
2(7x +7y) -(3x +14y) = 2(252) -(306)
11x = 198
x = 18
y = 252/7 -x = 36 -18 = 18
A small box costs $18, as does a large box.

The simplest form of the function is f(x) = x2. The graph is a parabola often called the basic parabola.
What is a parabola?A parabola is an approximately U-shaped, mirror-symmetrical plane curve in mathematics. It corresponds to a number of seemingly unrelated mathematical descriptions, all of which can be shown to define the same curves. A parabola can be described using a point and a line.
here, we have,
Three different parabolas exist. Vertex form, standard form, and intercept form are the three forms. You can access a unique key feature for the graph on each form.
Any point on a parabola is at an equal distance from both the focus, a fixed point, and the directrix, a fixed straight line. A parabola is a U-shaped plane curve.

If 10% of x is 20 what is 23% of x
Answer:
46 (23%)
Step-by-step explanation:
If 10% of x is 20, we can assume that 100% of x is 200. This is because since 10% is such a nice number to work with, we can simply add a zero to the end of it and the number. Now, we can see that 50% is 100 and 25% is 50. 20% is 40 and 10% is 20. 5% is 10 and 1% is 2. That being said, we need to do 50% + 3%. Which leaves us with 50 (25%) - 4 (2%). That being said, the answer is 46 (23%).

The endpoints of segment MP areM(-2,-4) and P(8,11) . If K portions MP in a ratios of MK:KP= 1:4, what are the coordinates of K?
Answer:
The coordinates of k are (-2,-1)
Step-by-step explanation:
Here, we are interested in calculating the coordinates of point k.
Mathematically, we will use the internal division formula for this;
This would be;
(x,y) =( nx1 + mx2)/(m + n), (ny1 + my2)/(m + n)
where m = 1 , n = 4
x1 = -2 , x2 = 8
y1 = -4 , y2 = 11
we now make the substitutions into the formula;
(x,y) = 4(-2) + 1(-2)/(1+4) , 4(-4) + 1(11)/(4 + 1)
(x,y) = (-8-2)/5 , (-16 + 11)/5
(x,y) = -10/5 , -5/5
(x,y) = (-2, -1)

You go shopping at a local department store with your friend and cousin. You buy one pair of jeans, four pairs of shorts, and two shirts for $84. Your friend buys two pairs of jeans, one pair of shorts and three shirts for $76. Your cousin buys one pair of jeans, two pairs of shorts and one shirt for $52. Find the cost of one pair of shorts.
Answer:
So, cost of 1 pair of shorts =$12
Step-by-step explanation:
Let cost of 1 pair of jeans =x
Cost 1pair of shorts =y
cost of 1 pair of shirts=z
We can set up equations as
x+4 y+2 z=84
2 x+1 y+3 z=76
x+2 y+z=52
Solve the equations for y.
Take first and second equations multiply first equation by -2 and add it with second equation.
-2 x-8 y-4 z=-168
2 x+1 y+3 z=76
Add them, it gives -7 y-z =-92
Now, take second and third equations, multiply the third equation by -2 then add them together.
2 x +1 y +3 z =76
-2 x-4 y-2 z=-104
Add them together,
-3 y +z =-28
Now, take the -7 y -z =-92 and -3 y +z =-28
Add the equations
-10 y = -120
Divide both sides by -10
y =12.
So, cost of 1 pair of shorts =$12
z=8

A deposit of $10,000 is made into an account that earns 6% interest. Use
your simple interest formula, I=Prt, to calculate the balance after 15 years
Answer:
$19,000
Step-by-step explanation:
The balance is the sum of the principal amount and the interest it earns:
A = P + I
A = P + Prt
A = P(1 +rt)
A = $10,000(1 +.06×15)

Let the function f be defined by f(x) = 12-5x
What value of a will make the equation f(a) = 6 true?
6/5
-18
-13
5/6
Answer:
6/5
Step-by-step explanation:
given that f(a) = 6
using x = a
f(x) = 12-5x
f(a) = 12 - 5a
since f(a) = 6
6 = 12 - 5 a
6 - 12 = 12 - 5a - 12
= -6 = -5a
= -6/-5 = -5a/-5
= a = 6/5
value of a is 6/5
what is 3x-2-7x = 10x + 4?
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3x−2−7x=10x+4
3x+−2+−7x=10x+4
(3x+−7x)+(−2)=10x+4(Combine Like Terms)
−4x+−2=10x+4
−4x−2=10x+4
Step 2: Subtract 10x from both sides.
−4x−2−10x=10x+4−10x
−14x−2=4
Step 3: Add 2 to both sides.
−14x−2+2=4+2
−14x=6
Step 4: Divide both sides by -14.
−14x−14=6−14

What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
3x-2-7x = 10x + 4
Now, solving for x
3x-2-7x = 10x + 4
-4x - 2= 10x + 4
-4x - 10x = 4 + 2
-14x = 6
x= -6/14
c= -3/7
Hence, the value of x is -3/7.

Step-by-step explanation:
30 degrees and 4x+2 are equal to 8+6x
First, write a formula or expression:
30 + 4x+2 = 8+6x
simplify this by collecting like terms
32 + 4x = 8+6x (minus 6x from both sides)
32 - 2x = 8 (minus 32 from both sides)
-2x = -24 (divide by -2)
x = 12
now sub into the formula:

CALCULATOR COLOR THEME 0 ZOOM 2. Danielle wants to translate triangle XYZ so that vertex Yis mov (-4,2) to (0,-3). Which of the following mappings can be used to coordinates of Xand Z?
Answer:The answer is (x,y)->(+4,y-5)
Step-by-step explanation:
since -4 to 0 is + 4 and 2 to -3 is -5
The correct mapping is (x, y) ⇒ (x + 4, y - 5)
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.
Translation is the movement of a point up, down, right or left in the coordinate plane. If a point A(x, y) is moved a units right and b units down, the new location would be at A(x + a, y - b).
Since the vertex Y(-4, 2) was translated to Y'(0, -3), hence the triangle was translated 4 units to the right (-4 + 4 = 0) and 5 units down (2 - 5 = -3). This can be represented by the mapping:
(x, y) ⇒ (x + 4, y - 5)
Therefore to find x and z coordinates, use the mapping:
(x, y) ⇒ (x + 4, y - 5)
