8/20=y/25
(0.4=y/25)*25
Y= 10
__________
8/20=(x+4)/15
0.4*15=x+4
6=x+4
X=2
So the ratio must be the same for the triangle to be the same
smallest side of 1 right triangle to smalles side of other right trigle shoudl be same as largest side of 1 right trignale to largest side of other right triangle and also middle side
6:10 should equal 10:26 should equal 8:24
treat as fraction
6/10=10/26=8/24?
3/5=5/13=1/3
we know that 3/5 is not equal to 1/3 so they are NOT SIMILAR
ratios are
3:5
1:3
5:13
the perimiter of the smaller is 6+8+10=24
perimiter of larger is 10+24+26=60
ratio of perimiters larger to smaller is 60:24=5:2
area is 1/2 base times height
longest side=hypotonuse
therefor other 2 sides must be base and height
area of smaller=8 times 6 times 1/2=24
area lf larger=10 times 24 times 1/2=120
ratio of larger ot smaller is 120:24=5:1
not similar
ratio of perimiter larger to smaler=5:2
ratio oif area larger to smaller=5:1
Answer:
The number is 21.
Step-by-step explanation:
First you need to solve for n.
So the equation would be 2n = |5n-63|
First you'd subtract 5n from each side, that would give you -3n=|-63|
Then you need to divide each side by -3 to get n=21.
~~~~~
To check, you can just plug 21 back into the equation.
2(21) = |5(21) - 63|
42 = |105-63|
42 = |42|
42 = 42
Answer:
the correct answer is 8.7
