The little lines on each side of the rhombus mean that all the sides are the same length.
We can set line LM and MN equal to solve for X, then we can solve the length of a side.
3x-3 = x+7
Add 3 to each side:
3x = x +10
Subtract x from each side:
2x = 10
Divide both sides by 2:
x = 10/2
x = 5
Now we have the value for x, replace x in one of the side formulas:
x +7 = 5+7 = 12
Each side = 12 units.
The perimeter would be 12 + 12 + 12 + 12 = 48 units.
A because 40% of 3500 is 40%
Answer:
58 number of dimes.
A. $5.8
B. 131.602 grams.
Step-by-step explanation:
A U.S. dime has a thickness of 
mm.
Now, Gary has a stack of dimes that is 
mm in height.
Therefore, Gary has 
dimes in total.
A. Now, each dime is equivalent to $0.1.
Therefore, the total value of the dimes that Gary has is $(0.1 × 58) = $5.8.
B. If each dime weighs 2.269 grams, then the mass of the entire stack of dimes will be (2.269 × 58) = 131.602 grams. (Answer)
Answer:
x=12
Step-by-step explanation:
We know that both triangles are congruent meaning corresponding parts are equal. We know that line LN=54 and that RT=LN meaning that RT also equals 54. With that information we can simply subtract 6 from 54 to get 48 then divide by 4 to get 12. Hope this helps!
