Answer:
put value of y in equation
6x + 3(2x-35) = 15
6x + 6x - 105= 15
12x = 15+105
x = 120/12
x = 10
now put value of x in first equation to find y
y = 2(10) -35
y = -15

The ratio of male to female students in a junior high
school is 13:17. Find the total population of the
school if there are 715 male students.
plsss.......answer
the total no of population=1650
13:17 first add the two numbers 13+17=30
then 13/30×y =715 , i make 13 at the numerator because it's males ratio
after that 30/13×13/30y =715 ×30/13
y =715×30/13
y =1650
after u find the total no it's simple to find the no of females
17/30×1650=935

Answer:
x = 15
Step-by-step explanation:
Simplifying
3x + (8x + 15) = 180
Reorder the terms:
3x + (15 + 8x) = 180
Remove parenthesis around (15 + 8x)
3x + 15 + 8x = 180
Reorder the terms:
15 + 3x + 8x = 180
Combine like terms: 3x + 8x = 11x
15 + 11x = 180
Solving
15 + 11x = 180
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-15' to each side of the equation.
15 + -15 + 11x = 180 + -15
Combine like terms: 15 + -15 = 0
0 + 11x = 180 + -15
11x = 180 + -15
Combine like terms: 180 + -15 = 165
11x = 165
Divide each side by '11'.
x = 15
Simplifying
x = 15
Answer:
x=15 Hope this helps :)

This is a very good question to have at your finger tips. No doubt it will show up on a test at some point. Make sure you understand the steps.
Consider the line x-2y=-1 What is the slope of a line parallel to this line? What is the slope of a line perpendicular to this line?
Answer:
slope of line that is parallel is 1/2
slope of line that is perpendicular is -2
Step-by-step explanation:
parallel lines have the same slope
perpendicular lines have slopes that are opposite and reciprocal
x - 2y = -1
-2y = -x -1
y = 1/2x + 1/2
the coefficient of the 'x' term represents the slope

solve for x...................................................................................
Answer:
x = 36°
Step-by-step explanation:
x + 20° + 4x = 200° { exterior angle of a triangle is equal to the sum of two opposite interior angles }
5x = 200° - 20°
5x = 180°
x = 180° / 5
x = 36°

A baseball team had 70 players show up for tryouts last year and this year had 85 players show up for tryouts. Find the percent increase in players from last year to this year.
Answer:percent increase in players from last year to this year= 7.14%
Step-by-step explanation:
percent increase = (Increase in number of players /Initial value of players Last year) x 100
value of players for tryouts last year = 70
value of players for tryouts this year = 85
Increase in tryouts = 85-70 =5
percent increase = 5/70 x 100
= 7.14%

Annual sales for a fast food restaurant are $650,000 and are increasing at a rate of 4% per year. What is the annual sales after 7 years?
Answer:
Around $855,355.66
Step-by-step explanation:
In these type of problems, you'd use the following equation
[tex]Initial Value * (percentage)^{x}[/tex]
Since the revenue's increasing by 4% every year, you'd plug 104/100 in the percentage box. X is the ammount of times the percentage is applied, so it would be 7, since we're finding the sales after 7 years. Finally, 650000 goes into the initial value and yeah. After calculating, you'll get around $855,355.66

The two objects are the same height, and the cylinder is just wide enough for the the box to fit inside with all 4 vertical edges of the box touching the inside of the cylinder. if the box of pasta fits 8 cups of rice, estimate how many cups of rice will fit inside the cylinder. Expalin or show your reasoing
Answer:
The answer is below
Step-by-step explanation:
The volume of a box with a length of l, width of w and a height of h is given by the formula:
volume of the box = length * width * height = lwh
The volume of a cylinder with a height of h, and radius r is given by the formula:
volume of the cylinder = π * radius² * height = πr²h
Since the box and the cylinder have the same height and the cylinder is wide enough for the box to be placed inside, this means that the box has a volume greater than that of the cylinder. Hence:
If the box can take 8 cups, the cylinder would be able to take 10 cups.

What’s the answer for this one??
Answer:
It is the second one.
Step-by-step explanation:
a and e are equal because they are mirrored. d and b are equal because they are on the same line and at the same point where the parallel lines go through. b and f are also mirrored. That leaves c and e which don't match.
