Answer:

Real easy PEMDAS situation here.

First we handle parentheses and we have a lot of 'em! Starting with the (6 x 5) and (4 + 1):

12 ÷ [(30 ÷ 5 ÷2) + 1]

Now, we handle the division left-to-right inside the parenthesis. 30 ÷ 5 = 6, then 6 ÷ 2 = 3:

12 ÷ (3 + 1)

Last bit of parentheses:

12 ÷ 4

Now divide:

3

EDIT: Changed the word "handled" to "handle." Just a word tense correction.

Write the equation for a line that is parallel to the line 2x + 3y = 6 and passes through the point (0,4)

The equation of a line parallel to the line 2x + 3y = 12 and passing through the point (0,4) is;

2x + 3y = 12.

To write the equation for a line parallel to the line 2x + 3y = 6; we must first determine the slope of the line.

By rewriting the equation 2x + 3y = 6 to resemble the standard slope-intercept form; we have;

y = (-2/3)x + 2.

Therefore, the slope, m1 of line 2x + 3y = 6 is;

- m1 = -2/3.

However, since the lines are parallel,

- m1 = -2/3 = m2.

Therefore, the equation of the parallel line which passes through the point (0,4) is given as;

- m2 = -2/3 = (y-4)/(x-0).

By cross product;

- -2x = 3y -12.

2x + 3y = 12

Therefore, the equation of a line parallel to the line 2x + 3y = 12 and passing through the point (0,4) is; 2x + 3y = 12.

Answer:

Step-by-step explanation:

Slope of a line 2x+3y=6 is -2/3

So line passing through (0,4) has same slope because both are parallel

From slope intercept form we have

Y-y1 =m(x-1)

Y-4= -2/3(x-0)

3Y-12 = -2x

3Y+2x = 12

Which is required equation of a line.

HIGH SCHOOL

A girl age is 28 years younger than her father the sum of their ages is 50 years find the ages of the girl and the father

Girl age is 11 years old

Fathers age is 39 years old

How to solve it:

Let the girls age be x years

Let the fathers age be (x+28) years

X+X+28=50

2x=50-28

2x=22

X=11

(11+28)= 39

Fathers age is 39 years old

How to solve it:

Let the girls age be x years

Let the fathers age be (x+28) years

X+X+28=50

2x=50-28

2x=22

X=11

(11+28)= 39
