12/150 = 8/x
12x = 150*8 .... cross multiply
12x = 1200
x = 1200/12 ... divide both sides by 12
x = 100
------------------
As confirmation:
12/150 = 0.08
8/100 = 0.08
This shows that 12/150 = 8/100

Answers
Answer:
Slope : -1
Y-intercept : (0,6)
Step-by-step explanation:
Answer:
Slope: -1
y-intercept: 6
Step-by-step explanation:
Lets figure out the slope with the formula, [tex]\frac{y2 - y1}{x2-x1}[/tex]. Take 2 coordinates and substitute them in. Lets take (-3,9) and (-1,7). Here are the steps:
[tex]\frac{7-9}{-1-(-3)}[/tex]
[tex]\frac{-2}{-1+3}[/tex]
[tex]\frac{-2}{2}[/tex]
[tex]-1[/tex]
Now we know that the slope is -1, so m = -1.
Lets figure out the y-intercept. We have to have an equation with the slope in it. Since we don't know the y-intercept yet, we will use the equation y = -x + b. Lets take the coordinate (5,1). Substitute the coordinates in. Here are the steps:
1 = -5 + b
b = 6
Now we know that the y-intercept is 6, so b = 6. I hope this helped!

Isabelle is plotting a pentagon on a grid.
So far, she has plotted and connected the three points shown on the grid below.
On a coordinate plane, lines connect points (negative 2, 4), (negative 3, 2), and (0, negative 2).
To find:
To complete the pentagon, choosing only from the points below. (2, 0), (–2, 0), (–2, 4), (2, 4).
How can Isabelle complete her pentagon?
Solution:
Consider the attached figure, while going through the following steps.
A five sided polygon is called the pentagon.
As Isabelle already plotted and connected the three points, we need to connect the remaining 2 points to obtain a pentagon.
So, from the attached figure, it's clear that, Isabelle needs to connect the points (2, 0) and (2, 4).
By plotting and connecting these above points, Isabelle can complete her pentagon.

Tyler bought a shirt from the 25% off rack. It normally costs $16. Here is the money he paid.
A ten dollar bill and two one dollar bills
Why did he pay $12? the options are (Sales Tax, Markup, Interest, Tip, Markdown, and Commission)
Answers
$16/4 = $4
$16-$4= $12
The item (the shirt in this case) was marked down
so, subtract 4 from 16 to get the marked down price of $12.
he paid $12 because the original price was marked down.
If 45.78 ÷ 1.7 is written in long division form as long division set up where 17 is on the outside of the division symbol and 45780 is on the inside so that the divisor is written as a whole number, where should the decimal point be placed in the dividend?
Between the 4 and the 5
Between the 5 and the 7
Between the 7 and the 8
Between the 8 and the 0
Please help ill give brainlest
Answers
The divisor is 1.7
The dividend is 45.78
We want 17 that is on the outside of the division symbol, written as a whole number.
45780 is on the inside of the division symbol.
So, to make 17 whole number, we will multiply it by 10. And we will also multiply 10 to 45.78 making it 457.80.
(multiplying with 10 means shifting decimal to one right place. Multiplying by 1000 means shifting decimal to 3 right places)
Hence, the dividend will be 457.80 and divisor will be 17.
Hope this helps :)

In which equation would you multiply both sides by 4.5 to get the variable alone?
A.6.1p = 4.5
B.p ÷ 6.1 = 4.5
C.p ÷ 4.5 = 6.1
D.4.5p = 6.1
Answers
If you multiply by both sides of the equation The 4.5 would cancel out on the left and you would be left with p=27.45
By applying the multiplication property, the equation you would multiply both sides by 4.5 to get the variable p alone is: C. p ÷ 4.5 = 6.1
Recall:
When applying the multiplication property of equality to find a variable, both sides of the equation will be multiplied by the same term/value.Therefore, for the equation p ÷ 4.5 = 6.1, which is:
p/4.5 = 6.1
To get the variable p alone, multiply both sides by 4.5
Thus:p/4.5 × 4.5 = 6.1 × 4.5
p = 27.45
Therefore, by applying the multiplication property, the equation you would multiply both sides by 4.5 to get the variable p alone is: C. p ÷ 4.5 = 6.1
