Answer:

The average difference in income and expenses each month is -150,

It shows every month the expenses is $ 150 more than income.

Step-by-step explanation:

Given formula of  average difference between his income and expenses each month,

A=\frac{I-E}{12}     ( Suppose A )

Where,

I = total income,

E = total expenses,

We have, I = $ 52,000, E = $ 53,800,

Thus, by substituting the values,

The average difference in income and expenses each month,

A=\frac{52000-53800}{12}=\frac{-1800}{12}=-\$150

Negative sign shows that the expenses exceed the income every month.

Given Mr. Engle’s total income, I = $52,000 and total expenses, E = $53,800, solving for average difference between income and expenses per month:
(I-E)/12 = ($52,000 - $53,800)/12
(I-E)/12 = - $1,800/12
(I-E)/12 = -$150
This means that Mr. Engle’s expenses exceed his income by an average of $150 each month in the said year.

svp [43]

Answer:

1 and 2/5 yards wastes only 1/15 a yard

Step-by-step explanation:

1 and 1/6 yards  would make a waste of 1 and 1/6 yards since you can't make a ribbon out of it. (incorrect)

1 and 2/10 yards  would make a waste of 1 and 1/5 yards since you can't make a ribbon out of it. (incorrect)

1 and 2/5 yards

1\frac{2}{5} -1\frac{1}{3} =\\\\1\frac{6}{15} -1\frac{5}{15} =\\\\\frac{1}{15}

Wastes 1/15 a yard.

1 and 1/2 yards  

1\frac{1}{2} -1\frac{1}{3} =\\\\1\frac{3}{6} -1\frac{2}{6} =\\\\\frac{1}{6}

It wastes 1/6 a yard.

2 yards

2-1\frac{1}{3} =\frac{2}{3}

It wastes 4/6 a yard.

PLSS HELPP BRAINLIEST AND 65 POINTS <br> pls do the graph too
Eddi Din [679]

Answer:

\Large \boxed{ -x+65}

Step-by-step explanation:

Two points are (0, 65) and (10, 55)

Calculate slope <em>m</em>

\displaystyle m=\frac{y_2 - y_1}{x_2 - x_1}

\displaystyle m=\frac{55-65}{10-0}=-1

Use slope-intercept form

y=mx+b

y=-1x+b

<em>b</em>  is the y-intercept, y-intercept is (0,65)

y=-1x+65
