Answer:
40
Step-by-step explanation:
let the unknown be y (x is used as times(multiplication) )
(y-17)x-6=-138
add /-6 to both sides
y-17x-6/-6=-138/-6
y-17=23
make y independent/add 17 to both sides
y-17+17=23+17
y=40
or in an easier way
-138/-6 =23
23+17=40

Find the distance between −340 and 207 on the number line.
Answer:
547
Step-by-step explanation:
To find the difference between the 2 numbers, subtract -340 from 207:
207 - (-340)
Subtracting a negative number will change to adding a positive number:
207 + 340
= 547
So, the distance is 547

말 8.) A baker is ordering eggs for the week. How many cartons of 6 eggs would a baker need to have 225 eggs all together? Explain the reasoning for your answer. (4 pts.)
Answer:
38
Step-by-step explanation:
We know that each carton contains 6 eggs and we need a total of 225. To find this answer, divide 225 by 6, which is 37.5. We would have to round up one because you cannot buy half of a carton. So the answer is 38 cartons.
BD=16 and ÁT is the
perpendicular bisector of BD. Y=?
Answer:
[tex]y= 5[/tex]
Step-by-step explanation:
Given
[tex]BD = 16[/tex]
[tex]BC = 2y - 2[/tex]
[tex]CD = y + 3[/tex]
Required
Find y
[tex]BD = BC + CD[/tex]
So, the expression becomes
[tex]16 = 2y - 2 + y + 3[/tex]
Collect like terms
[tex]16 = 2y + y- 2 + 3[/tex]
[tex]16 = 3y+1[/tex]
Collect like terms
[tex]3y = 16 - 1[/tex]
[tex]3y = 15[/tex]
Make y the subject
[tex]y= 15/3[/tex]
[tex]y= 5[/tex]

A closed rectangle box with a volume of 16 3 ft is made from two kinds of materials. The top and bottom are made of material costing 10 cents/ 2 ft and the sides from material costing 5 cents/ 2 ft . Find the dimensions of the box so that the cost of the materials is minimized. [Hint: The cost of each side is equal to the area of the side times its unit price]
Answer:
The dimensions of the box are;
2 feet, by 2 feet, by 4 feet
Step-by-step explanation:
The given parameters are;
The volume of the closed box = 16 ft³
The material with which the top is made = The material with which the bottom is made
The cost of the material with which the top and bottom is made = 10 cents/(ft.²)
The cost of the material with which the side is made = 5 cents/(ft.²)
Let 'x', 'y', and 'z' represent the length, width, and height of the material, we have;
x·y·z = 16...(1)
The total cost of the box = 2×10×x×y + 2×5×x×z + 2×5×y×z
∴ The total cost of the box = 20·x·y + 10·x·z + 10y·z...(2)
From equation (1)
z = 16/(x·y)
Therefore, we have;
20·x·y + 10·x·z + 10y·z. = 20·x·y + 10·x·16/(x·y) + 10y·16/(x·y)
20·x·y + 160/(y) + 160/(x)
Differentiating, we get;
f'(x) = 20·y - 160/x²
f'(y) = 20·x - 160/y²
20·y - 160/x² = 0
y = 8/x²
20·x - 160/y² = 0
x = 8/y²
∴ x = 8/(8/x²)² = x⁴/8
8 = x⁴/x = x³
x = ∛8 = 2
The length, x = 2 feet
y = 8/x² = 8/2² = 2
The width, y = 2 feet
z = 16/(x·y) = 16/(2 × 2) = 4
The height of the box, z = 4 feet
Therefore, the dimensions of the box are 2 feet, by 2 feet, by 4 feet.

Why did the 30-60-90 triangle marry the 45-45-90 triangle
Answer: because they were right for each other.
Step-by-step explanation:
The cause due to which the triangles 30-60-90 married the triangle 45-45-90 would be:
They were right for each other.
Sum Property of TriangleThe sum of property of triangle states that the three angles of triangle give the sum of 180°.
Given that,
Two sets of triangles having the measures:
First set = 30°-60°-90°
Second set = 45°-45°-90°
The first set marries the other as they both are right i.e. 90° to one another and give an equal sum of 180°.
Thus, the above answer is correct.

Write an equation in the form y = mx + b of the line that is described. The line has the same y-intercept as the line whose equation is y = - 2 + x and is
parallel to the line whose equation is 3x + 3y = 6.
Answer:
y=x+2
Step-by-step explanation:
So, our line has the same y intercept as the equation is y=-2+x, and parallel to 3x+3y=6
We want to write the equation in y=mx+b form, where m is the slope and b is the y intercept
The y intercept of y=-2+x is -2, (we can rearrange it to be y=x-2) so that's the y intercept of our line
so far, here's our line:
y=mx-2
First, let's put 3x+3y=6 into slope-intercept form
subtract 3x from both sides
3y=-3x+6
divide by 3
y=-x+2
Perpendicular lines are negative and reciprocal; if you multiply their slopes together, the result is -1.
The slope for y=-x+2 is -1.
To find the slope of the new line:
-1m=-1
divide by -1
m=1
The slope of our line is 1
here's our line:
y=x+2
