"<span>The sum of the squares of the digits is 26"
</span>10t + u = 26 ---->(1)
<span>"If the number is decreased by the number with its digits reversed, the result is 36"
u - 10t =36 -----> (2)
By subtracting the equation we can find t.
</span> u+10t = 26)<span>
-(u-10t=36)</span>
______________
0u +20t = 26 -36
---> 20t = -10
t= -10/20
t= -1/2
Inserting value t in (1)
10t + u = 26
10(-1/2) + u= 26
-5+u=26
u= 26+5 = 31
<span>
Using u and t in the original expression 10t+u express a positive number
10t+u
= 10(-1/2) +u
= -5 + 31
= 26
----> Proves this statement is true

Answer:
2 nickels, 9 dimes
Step-by-step explanation:
When there are a number of overlapping shaded areas on the graph, I find it convenient to use the reverse of the inequalities. That makes the <em>unshaded</em> area the solution space. Here, the vertices of the triangular solution space are ...
(2, 9), (2, 13), (6, 9)
Any of the grid points within (or on) this triangle is a possible solution. One of them is (2, 9) corresponding to 2 nickels and 9 dimes.

Three solutions are shown:
(x, y) = (2, 9), (3, 10), (4, 11)
Answer:
A
Step-by-step explanation:
I think its A because if you see the line which is the slope, the slope is going up, so its positive. to find the x, you use ride over run. also, you see the y intercept is up and its positive. sorry if I get it wrong.
I hope it helped!!!:)
This is easy,
For the first one.
just add 1.3m + 45cm which equals = which equals 46.5 meters.
Amount would be: 4500 * 9%
= 4500 * 0.09 [ 9% = 0.09 ]
= 405
In short, Your Answer would be: $405
Hope this helps!
