Step-by-step explanation:

total number of student = 900number of girls = 300

1) to find the number of boys

number of boys = total no. of students - no. of girls

= 900 - 300

= 600

2) to find the ratio of boys and girls

ratio of boys and girls = no. of boys : no. of girls

= 600 : 300

= 200

3) ratio of boys and total no. of students

= 600 : 900

= 200: 300

= 2:3

4) ratio of girls and total no. of students

= 300 : 900

= 1:3

5)ratio of girls and boys

= 300 : 600

= 1:2

both equations equal to y so you can put them together

3/5x+4=-x+4

separate the variables and numbers...

1.6x=0

x=0

y=4

if ur using a graph, use the y intercept (0,4) for your first point

then, using y=-x+4, make -x a fraction -1/1

by using rise/run go down one unit from (0,4) since its negative 1

then one unit to the right from where you are

you should be able to connect the points for the first equation

Step-by-step explanation:

Step-1: Simplify the distributive property

⇒ [tex]\dfrac{35a}{14} - \dfrac{35}{21} - \dfrac{(3a + 6)}{12}[/tex]

Step-2: Make common denominators

⇒ [tex]\dfrac{35a \times 3}{14 \times 3} - \dfrac{35 \times 2}{21 \times 2} - \dfrac{7 \times (3a + 6)}{12 \times 7}[/tex]

⇒ [tex]\dfrac{210a}{84} - \dfrac{140}{84} - \dfrac{7 \times (3a + 6)}{84}[/tex]

Step-3: Simplify the distributive property

⇒ [tex]\dfrac{210a}{84} - \dfrac{140}{84} - \dfrac{21a + 42}{84}[/tex]

Step-4: Rewrite (21a + 42)/84 in a different way

⇒ [tex]\dfrac{210a}{84} - \dfrac{140}{84} - \dfrac{21a}{84} + \dfrac{42}{84}[/tex]

Step-5: Add/Subtract if necessary

⇒ [tex]{\dfrac{189a}{84} - \dfrac{98}{84}}[/tex]

Step-6: Simplify the fractions

⇒ [tex]{\dfrac{189a}{84} - \dfrac{98}{84}} = {\dfrac{9a}{4} - \dfrac{49}{42}} = \boxed{\dfrac{9a}{4} - \dfrac{7}{6}}[/tex]
