Answer: x=-1
Step-by-step explanation:
−10+x+4−5=7x−5
−10+x+4+−5=7x+−5
(x)+(−10+4+−5)=7x−5(Combine Like Terms)
x+−11=7x−5
x−11=7x−5
Step 2: Subtract 7x from both sides.
x−11−7x=7x−5−7x
−6x−11=−5
Step 3: Add 11 to both sides.
−6x−11+11=−5+11
−6x=6
Step 4: Divide both sides by -6.
−6x
−6
=
6
−6
x=−1
250 percent of 8.2 is 20.5
Answer: 30.2
Explanation:
The mean is calculated by taking the sum of the values and dividing by the count.
For instance, for the 6 women, with the mean being 31, we can see that the ages summed to 186:
186
6
=
31
And we can do the same for the men:
116
4
=
29
And now we can combine the sum and count of the men and women to find the mean for the office:
186
+
116
10
=
302
10
=
30.2
Step-by-step explanation:
so we know that each m&m weighs about 2g.
the next line says to write a direct variation equation.
(definition: mathematical relationship between two variables that can be expressed by an equation in which one variable is equal to a constant times the other)
we then make the equation ( w=xm), then we use that equation to figure out the next line, which is to find the amount of m&ms that would fit in a bag of 1000.
(my head cant really process part a cause of a recent headache, so sorry if its wrong)
the answer to part b would be 500, which you can provide evidence based off of your part a equation.
