Let the two numbers be x and y.
According to your question;
x + y = 7
10y + x = 10x + y + 9
By equation 1 ; x = 7-y
Substituting the value of x ;
10y + ( 7 -y) = 10(7-y) + y + 9
9y + 7 = 70 -10y + y + 9
9y + 7 = 70 - 9y + 9
=> 18y = 70 -7 + 9
=> 18y = 72
=> y = 4
Substituting for x ;
x = 7 - y
=> x = 7 -4
=> x = 3
Thus, x = 3 and y = 4;
=> The number is 34.
Answer:
180 / 210 = 0.85714286
0.85714286 X 100 = 85,714286
85,71%
Step-by-step explanation:
No, because 8-1-2 is literally 5 and 7-3 equals 4 so no because the answer don’t match
B. 3
the preimage points were both multiplied by 3, if it were to go from (12, -6) to (4, -2), that would be 1/3
10cm because the base and height have to be same as it’s a square and 10 x 10 is 100
