8 employees exercise at least three times a week
<em><u>Solution:</u></em>
At the office where Mika works 41% of the 19 employees exercise at least three times a week
To find: Number of people who exercise at least three times a week
From given information,
Total employees = 19
Employees exercise at least three times a week = 41 % of total employees
Therefore, we have to evaluate 41 % of 19
Number of people exercise at least three times week = 41 % of 19
Thus approximately 8 employees exercise at least three times a week
Answer:
a = -6/5
Step-by-step explanation:
For the graphs to be parallel the graphs should have same slope(m)
So we rewrite both our equations in the slope-intercept form then compare the slope to find the value of a like this,
This equation is the slope-intercept form we convert both our equations in this form firstly taking equation 1
so if we compare it with y = mx + b the coefficient of x is m and hence
m= -2/5 now solving for equation 2
so here if we compare it with y = mx + b the coeffienct of x is a/3 so since parallel lines have same slope by the formula:
we equation both the slope to each other to find the value of a like this,
so the value of a equals
a= -6/5
Answer:
4+ 
x = 3
Step-by-step explanation:
4 + x = 3 (subtract 4 from both sides)
x = -1 (multiply both sides by 2)
x = -2
Answer:
Cost of a pound of chocolate chips: $3.5
Cost of a pound of walnuts: $1.25
Step-by-step explanation:
x - cost of a pound of chocolate chips
y - cost of a pound of walnuts
We create two equations based on the information we have:
3x+2y=13
8x+4y=33
The whole point of these problems os to get rid of x or y. In this question, we can do this by multiplying both sides of the first equation by 2, and then subtracting it from the second equation:
8x+4y=33
6x+4y=26
2x=7
x=3.5
Then we change x for 3.5 in the first equation:
3×3.5+2y=13
10.5+2y=13
2y=2.5
y=1.25
Hope this helps!
Answer:
33.33%
Step-by-step explanation:
- Number of boys=10
- Number of girls=20
- Total number of students=
Number of boys + Number of girls
10+20
30
10/30×100%
33.33%
