x = 0.17(repeating 7) (1st)
10x = 1.77 (2nd)
subtract (1st) from (2n)
9x = 1.77 - 0.17
9x = 1.6
90x = 16
x = 16/90
x = 8/45
answer
8/45
Answer:
The answer for this as a fraction would be 1260/1
Step-by-step explanation:
63 ÷ 5/100
Option D x = -8 is correct option.
Step-by-step explanation:
We need to solve the inequality:
Solving:
All the values less than 7 are included in the number line.
The graph on number line is shown in figure attached.
In the options given, all values in Option A, B and C are greater than 7 so these cannot be included.
while Option D is less than 7 so, x=-8 is correct
Option D is correct.

The answer to this question would be: a^2 b^2
In this question, you have two variable ( a and b) with some exponent. To make the number express positive exponent, you can switch it location from denominator to numerator position, or vice versa. In this case, the calculation would be:
a^3 * b^-2 / a^1 b^-4=
a^3 * b^4 / a^1 b^2=
(a^3 / a^1) * (b^4/b^2)=
a^(3-1) * b^(4 -2)=
a^2 * b^ 2
Answer:
54
Step-by-step explanation:
Since these two angles are vertical angles, they must be congruent. Therefore we can set up the following equation:
2x+2=3x-52
Subtract 2x from both sides:
2=x-52
x=54
