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)
Hope this helps!

Q.10) John makes clay cups. He makes 18 cups each hour. He makes cups

all the cups John makes in a week?*

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

A farmer has a square plot of land he needs defense he walked to the diagonal of the plot of land and found it to be 80 yards how much fencing will he need to fence the plot of land?
Answer: i think the answer is 320
Step-by-step explanation:
i say 320 because a square has 4 sides and there is 80 yards so all i did is multiply 80 x 4 = 320
Answer:
Step-by-step explanation:
[tex]d^2=x^2+x^2\\ \\ 2x^2=80^2\\ \\ 2x^2=6400\\ \\ x^2=3200\\ x=\sqrt{3200}\\ \\ P=4x\\ \\ P=4\sqrt{3200}yds\\ \\ P\approx 226.27yds[/tex]

Use the drop-down menus below to create an equation that represents the line on the graph.
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.

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
7x = 42
x = 42 ÷ 7
x = 6

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
