Answer:
Janet has coins worth 252.5, 101, and 50.5.
Step-by-step explanation:
Let us call the three coins 
, and 
.
The first coin 
is 5 times another coin<em> (let's say </em>
); therefore,
,
and the third coin is 2 times the value of another coin<em> (it's coin </em><em>):</em>
<em />
<em>.</em>
The total worth of all coins is 404; therefore,
or
with the value of in hand, we find and :
and for 
Thus, Janet has 3 coins worth 252.5, 101, and 50.5.
Answer:
x=27
Step-by-step explanation:
The sum of the angles of a triangle is 180 degrees
90 + x+23 + x+13 = 180
Combine like terms
126 +2x = 180
Subtract 126 from each side
126-126 +2x=180-126
2x =54
Divide by 2
2x/2 = 54/2
x = 27
Answer:
It decreases by 4 units
Step-by-step explanation:
The surface area would be all those areas combined. The shape has been split up into 6 smaller quadrilaterals, so we can easily solve from there. The leftmost one would be 3*4 = 12. The two rectangles beside it can be combined: 4*7 = 28, the one beside it would be: 3*4 = 12, and the last column would be 4*7 = 28. The last thing you need to do is add them together: 12+28+12+28 = 80.
The surface area of the rectangular prism is 80
Answer:
um I dont think any of those are right it should be 625
