Answer:
15 cm
Step-by-step explanation:
Similar triangles are triangles which have the same shape but not the same size. This means their angle measures are equal but their side lengths are not instead they are proportional. To solve, we will set up a proportion and solve.
A proportion is two equal ratios set equal to each other. We form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). Out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:
.
To solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
Divide by 90%.

Answer: 24 necklaces
Step-by-step explanation:
y=240+2x is the amount she spends
y=12x is the amount she makes
If the amount she spent = the amount she makes then she break even
240+2x=12x
240=12x-2x
240=10x
So x = 240/10=24 necklaces she needs to sell to break even
Answer is 24 necklaces
Hope this helps!!! Good luck!!! ;)
Answer:
top left
Step-by-step explanation:
it is the only one that shows W at 1,4
Answer:
x = 2 (doesn’t work in the equation)
3(2) -3 = 3 - 6(2)
X = 2/3 (works in the equation
3 (2/3) - 3 = 3 - 6(2/3)
2-3 = 3 - 4
- 1 = -1
Step-by-step explanation:
|3x| - 3 = 3 - 6x
|3x| = 3 + 3 - 6x
|3x| = 6 - 6x
|3x| = -6 + 6x
3x = - 6 + 6x or 3x = 6 - 6x
6 = 6x - 3x
6 = 3x
x = 2
3x = 6 - 6x
3x + 6x = 6
9x = 6
x = 6/9
x = 2/3
