Answer: D. n = 12

================================

Work Shown:

n/33 = 4/11

11*n = 33*4 ... cross multiply

11n = 132

n = 132/11 ... divide both sides by 11

n = 12

Answer:

D: n = 12​

Step-by-step explanation:

n/33=4/11

we multiply by 33

n=4*33/11

33 can be divided by 11

n=4*3

n=12

a father is 25 years older than his son.Five years ago he was 6 time old as his son was find their presents
IceJOKER [234]

Answer:

the present age of the father be x and the present age of the son be y.

It is given that man is 24 years older than his son that is:

x=y+24

x−y=24..........(1)

Also, 12 years ago, he was five times as old as his son that is:

(x−12)=5(y−12)

x−12=5y−60

x−5y=−60+12

x−5y=−48..........(2)

Now subtract equation 1 from equation 2 to eliminate x, because the coefficients of x are same. So, we get

(x−x)+(−5y+y)=−24−48

i.e. −4y=−72

i.e. y=18

Substituting this value of y in (1), we get

x−18=24

i.e. x=24+18=42

Hence, the present age of the father is 42 years and the present age of the son is 18 years.

LOOK AT CHART BEFORE THE BULLET PART:
Ber [7]

Answer:

1st blank: \text{Slope(m)}=-\frac{3}{4}

2nd blank: \text{y-intercept}=399

3rd blank: Slope-intercept form:y=-\frac{3}{4}x+399

Step-by-step explanation:

Let x be the number of sandwiches and y be the number of wraps.

We have been given a chart of values, which represents Sal's total profit on lunch specials for two months. We are asked to fill in the empty boxes.

We have been given that Sal gets a profit of $3 after selling each sandwich, so Sal's profit after selling x sandwiches will be 3x.

As each wrap gives a profit of $4, So Sal's profit after selling y wraps will 4y.

Since Sal’s total profit on lunch specials for next month is $1596. We can represent this information in an equation as:

3x+4y=1596

We can see that our equation is in standard form, so let us convert it in slope-intercept form of equation.

Since we know that equation of a line in slope-intercept form is: y=mx+b, where,

m = Slope of line,

b = y-intercept or initial value.

Let us subtract 3x from both sides of our equation.

3x-3x+4y=1596-3x

4y=1596-3x

Let us divide both sides of our equation by 4.

\frac{4y}{4}=\frac{1596-3x}{4}

y=\frac{1596}{4}-\fraxc{3x}{4}

y=399-\frac{3}{4}x

y=-\frac{3}{4}x+399

Therefore, equation y=-\frac{3}{4}x+399 represents the Sal's total profit for 2nd month in slope-intercept form of equation.

Upon comparing our equation with slope-intercept form of equation we can see that slope of our line is -\frac{3}{4} and y-intercept is 399.
