Answer: 47, 74
Step-by-step explanation:
Let x = units digit
x – 3 = tens digit
Then the number is 10(x – 3) + x and the reversed number is 10(x) + (x – 3)
Equation
The reversed number plus the original number equal 121.
10(x) + (x – 3) + 10(x – 3) + x = 154
10x + x – 3 + 10x -30 + x = 121
22x – 33 = 121
22x = 154
x = 7 (units digit)
x – 3 = 4 (tens digit)
Answer
The number is (4 X 10) +7 or 47.
Answer:
<em>4x - 2</em>
Step-by-step explanation:
Simplify the expression:
First, we must remove the parentheses. The minus sign before them indicates we must apply the distributive property of multiplication, multiplying all the internal terms by -1:
Once the expression is free from parentheses, we collect like terms. There are two pairs of like terms: the terms with x, and the terms with only numbers.
Rearrange the expression:
Operating: -2+6=4, and 3-5=-2
The simplified expression is:
4x - 2

C
plug in the numbers
first know that 2^0 = 1, as any number to the power of 0 is 1
so 2^0(10) = 10
And if you keep plugging it in youll notice they all fit
-6 + 4 + 2 + 0 + -7 + 6 + -2 +2 = -1
-1 ÷ 9 = -0.111111111111111111111111111
-0.111 is your answer
ask if you have any questions : )
