5x-x=-2-7
4x=-9
x=2/3 or x=-2/3
Since there are 2 answers, it is not one solution.
Answer:
income tax=13% of total salary
Step-by-step explanation:
Here,
let salary be 'x'
Now,
13%of x = $10 000
13/100 × x = $10 000
13x = 1000000
x=10 00000/13
Therefore x =76,923.0769
His salary that year was 76,923.0769
Answer:
<u>The correct answer is A. - 11 square root of 7.</u>
Step-by-step explanation:
We have the expression 2 √28 - 5 √ 63 and we have to find and equal expression.
Let's simplify it:
2 √28 - 5 √ 63
2 √7 * 4 - 5 √ 9 * 7 (28 is also equal to 7 * 4 and 63 is equal to 9 * 7)
2 * 2 √7 - 5 * 3 √ 7
4 √7 - 15 √7
- 11 √7
<u>The equal expression is A. - 11 square root of 7.</u>
The expressions which equivalent are letter A, 3x-7y and -7y+3x, because the order of the factor do not change the product or the final answer.
When you are seeing which number is bigger first you look at the first digit
<u></u>0.<u>8</u>3 or 0.<u>8</u>02
^8 ^8
If they equal the same, look at the second digit
0.8<u>3</u> or 0.8<u>0</u>2
^3 ^0
3 is greater than 0
<u>0.83 is larger
</u>
you can also look at it this way:
0.83 = 0.830
What is bigger
0.802 or 0.830?
0.83 is bigger
