Lila wrote an equation of the cost for printing brochures, where x represents the number of brochures and y represents the total

cost. The total cost for 35 brochures is $41.45. The total cost for 65 brochures is $55.55.
Step 1: Write the ordered pairs mc017-1.jpg and mc017-2.jpg.

Step 2: Find the slope. mc017-3.jpg

Step 3: Find the y-intercept to write the equation in slope intercept form. mc017-4.jpg

Which explains the error that Lila made?
Lila made in error in Step 1 by reversing the ordered pairs.
Lila made an error in Step 2 by not using the slope formula.
Lila made an error in Step 3 when she did not use the x- and y-coordinates from the same ordered pair.

What is 5/12 minus 3/20
anyanavicka [17]
\frac{5}{12} - \frac{3}{20}

First, find the LCD of the two fractions.
Multiples of 12: 12, 24, 36, 48, 60.
Multiples of 20: 20, 40, 60
The LCD is 60.
Second, change the denominators to be the same as the LCD.
\frac{5x5}{12x5} - \frac{3x3}{20x3}
Third, 5 × 5 = 25 / 12 × 5 = 60 / 3 × 3 = 9 / 20 × 3 = 60
\frac{25}{60} - \frac{9}{60}
Fourth, combine the denominators.
\frac{25-9}{60}
Fifth, subtract 25 - 9 to get 16.
\frac{16}{60}
Sixth, find the GCF of 16 and 60.
The GCF is 4.
Seventh, divide the numerator by the GCF.
16 ÷ 4 = 4
Eighth, divide the denominator by the GCF.
60 ÷ 4 = 15
Ninth, rewrite the fraction in simplest form.
\frac{4}{15}

Answer as fraction: \frac{4}{15}
Answer as decimal: 0.2667

Each year, Kipp raises money by participating in the Walk for Breast Cancer. Last year, Mr. Madrid walked at a pace of 12 miles
Ilia_Sergeevich [38]
A.

The rate is 12:2

B.

Set up a proportion:

12/2 = x/5

Multiply 5 to both sides:

60/2 = x

Divide:

30 = x

So he will walk 30 miles in 5 hours.

C.

To find out, we can divide 12 / 2.

12 / 2 = 6 miles per hour
