Answer:
k = 54/79
Step-by-step explanation:
You can eliminate fractions by multiplying both sides by 12.
15(2 -k) = 24(3k -1) -8k
30 -15k = 72k -24 -8k
54 = 79k
54/79 = k

Correct question is;
John makes clay cups. He makes 18 cups each hour.
He makes cups for 6½ hours each day, on 5 days of the week.
The cups are packed in boxes.
4 cups are packed into each box.
How many boxes are needed for
all the cups John makes in a week?
585
146.25
146
147
Answer:
147
Step-by-step explanation:
Since he makes 18 cups each hour and we are told that he makes it for 6½ hours each day.
Thus, amount of cups made per day = 18 × 6½ = 18 × 13/2 = 117 cups
She works 5 days a week.
This means;
Cups produced for the week = 117 × 5 = 585 cups
We are told that the cups are to be packed in boxes. Also that 4 cups are packed into each box.
Thus, number of boxes = 585/4 = 146.25 boxes
Since, we can't have a decimal as number of boxes, to fit everything we approximately need 147 boxes

If the line containing the points (-2,10) and (7, 4) is dilated by a factor of 2, what is the
slope of the image?
ASAPPP NUMBER 2
===================================================
Explanation:
Let's compute the slope of the line through the two original points
m = (y2-y1)/(x2-x1)
m = (4-10)/(7-(-2))
m = (4-10)/(7+2)
m = -6/9
m = (-2*3)/(3*3)
m = -2/3
The slope is -2/3
-------------
Now apply the scale factor.
We'll multiply each coordinate of each point by 2
(-2,10) becomes (-4,20) after multiplying each coordinate by 2
(7,4) becomes (14,8) after multiplying each coordinate by 2
Let's find the slope of the line through (-4,20) and (14,8)
m = (y2-y1)/(x2-x1)
m = (8-20)/(14-(-4))
m = (8-20)/(14+4)
m = -12/18
m = (-2*6)/(3*6)
m = -2/3
We get the same slope. This isn't a coincidence. Dilating a set of points will preserve the slope of the line through those points.
If A and B are the two original points, and A' and B' are the dilated counterparts, then the slope of line AB is the same as the slope of line A'B'.
The scale factor doesn't affect the answer.

They subtracted 5 on both sides of the equation. They were suppose to add 5 on both sides of the equation for it to cancel out each other. If you need any further explanation, please ask me :)
Correct version:
5y + (-5) = 10
+5 +5 add 5 to both sides, 5's will cancel out on left side.
___________
5y 15
__ = __ divide 5 on both sides, 5's will cancel out on left side.
5 5
y = 3, final answer
Answer:
its the first part the (-5) -5 is supposed to be (-5) +5
Step-by-step explanation:
so the equation is 5y=15
then you divide 5y/5 is y so then you 15/5 is 3
so the answer is y=3

How to construct the inscribed circle of a triangle?
Inscribed circle of a triangle is the largest circle, contained in the triangle.
Steps to construct the inscribed circle of a triangle-
Step 1-Bisect one of the angle of the triangle.Step 2-Now bisect the another angle of the triangle.Step 3-The crossing point of both the angle bisects is the in center of the triangle and center of the required circle.Step 4- Draw a perpendicular from this center to one of the side of the triangle.Step 5-Now draw a circle using the compass with the in center as a center of the and radius equal to the perpendicular from the in center to one of the side.Thus to construct the inscribed circle of a triangle the in-center is required. the option 3 is the correct option.

Answer:
[tex]y=2\frac{1}{6}[/tex] or [tex]\frac{13}{6}[/tex]
Step-by-step explanation:
We know that [tex]x[/tex] and [tex]y[/tex] are directly proportional. Therefore, using the given information, we can set up the following proportion:
[tex]\frac{6.5}{12}=\frac{y}{4}[/tex]
Solving for [tex]y[/tex], we get:
[tex]\frac{6.5}{12}=\frac{y}{4}[/tex]
[tex]12*y=6.5*4[/tex] (Cross-Products Property)
[tex]12y=26[/tex] (Simplify)
[tex]\frac{12y}{12} =\frac{26}{12}[/tex] (Divide both sides of the equation by [tex]12[/tex] to get rid of [tex]y[/tex]'s coefficient)
[tex]y=2\frac{1}{6}[/tex] or [tex]\frac{13}{6}[/tex] (Simplify)

Can anyone solve this for me?
Answer:
4x + 3 = 11
4x = 11 - 3
4x = 8
x = 8 ÷ 4
x = 2
3x - 5 = 7
3x = 7 + 5
3x = 12
x = 12 ÷ 3
x = 4
8x - 5 = -37
8x = -37 + 5
8x = -32
x = -32 ÷ 8
x = -4
7(x - 3) = 21
7x - 21 = 21
7x = 21 + 21
