<h2>
Answer:</h2>
The number is -2.
<h2>
Step-by-step explanation:</h2><h3>Written out, our equation looks like this:</h3><h3>(-5·x)+2=12</h3>
We'll start of by taking our final result of 12 and subtracting 2, as the beginning of the statement says "two more."
<h3>12 minus 2 gives us
10.</h3>
Now, since the statement says "the product of -5," we will take this 10 and divide by -5.
<h3>10 divided by -5 gives us -2.</h3>
This means that our number, x equals -2. Of course, we must input this solution to double check our work.
<h3>(-5·<u>
-2</u>)+2=12</h3><h3>10+2=12</h3><h3>12=12</h3>
<h2>Our final answer is x=-2!</h2>
If the data set represents the number of rings each person is wearing, being: 0,2,4,0,2,3,2,8,6, the interquartile range of the data is 2. Being, 4 as the Q1, 3 as the Q2 or median, and 6 as the Q3. Where the formula of getting the interquartile range is IQR= Q1-Q2.
Answer:
A) 37:191
B)191:154
Step-by-step explanation:\
A) Mary's Savings= 185 Rs
Mary's Income= 955 Rs
Ratio = 185:955
= 185/955
=37/191 ( INTO LOWEST TERMS )
=37:191
B) Mary's Income= 955 Rs
Mary's Expenditure= ?? = Income- Saving = 955-185= 770
Ratio= 955:770
= 955/770
= 191/154 ( INTO LOWEST TERMS )
= 191:154
3sinx+1=sinx
2sinx+1=0
2sinx=-1
sinx=-1/2
x=sin^-1 (1/2) = 30 =
/6 (when finding the inverse, always take the positive value, ignore the negative sign)
x is therefore negative in 3rd and 4th quadrant
Therefore values of x are:
180+30=210 = 7
/6
360-3=330 = 11
/6
18.70
Because they are 1.10 each
