x=-5
<h3>
Answer: 37</h3>
====================================================
Work Shown:
T = tens digit of the original number
U = units digit of the original number
U+T = 10 since the digits add to 10. Solve for U to get U = 10-T
10T+U = original number
10U+T = new number where digits are reversed
-----------
new number = (old number) + 36
10U+T = (10T+U)+36
10U+T = 10T+U+36
10(10-T)+T = 10T+10-T+36 ... plug in U = 10-T
100-10T+T = 10T+10-T+36
-9T+100 = 9T+46
100-46 = 9T+9T
54 = 18T
18T = 54
T = 54/18
T = 3 is the tens digit of the original number
U = 10-T
U = 10-3
U = 7 is the units digit of the original number
10T+U = 10*3+7 = 30+7 = 37 is the original number
73 is the reversed number.
73-37 = 36 is the difference, showing that 37 increased by 36 leads to 73. The answer is confirmed.
Answer:
4/6 i tink i am not sure if am rong let me now
Step-by-step explanation:
With the given inequalities, the best answer is the middle graph. Getting the values for x, we obtain x>5 and x>=1. The middle graph shows that the value of x is all real numbers greater than or equal to 5. This best satisfies both equation as the two values for x requires real number greater than 5 and greater than or equal to 1 respectively.
Answer:
<u> 10 +√10</u>
Step-by-step explanation:
Given the coordinates of the triangle expressed as
A(-1,6), B(-1, 1) and C(2,2)
The perimeter of the triangle= AB + BC + AC\
Since AB = AC
P = AC + BC + AC
P = 2AC + BC
get the length AC using the formula;
Given A(-1,6) and C(2,2)
AC = √(2-(-1))²+(2-6)
AC = √3²+4²
AC = √9+16
AC = √25
AC = 5
Get BC
B(-1, 1) and C(2,2)
BC = √(2-(-1))²+(2-1)
BC = √3²+1²
BC = √9+1
BC = √10
Perimeter = 2(5)+√10
Perimeter = 10 + √10
Hence the perimeter of the triangle is<u> 10 +√10</u>
