Answer:

$-\frac{7}{8}a-\frac{1}{6}$ (the first box is 7/8 and the second box is 1/6)

Step-by-step explanation:

Step 1: Combine like terms.

$(-\frac{5}{8}a-\frac{1}{4}a)+(\frac{2}{3} -\frac{5}{6})$
$(-\frac{5}{8}a -\frac{2}{8}a)+(\frac{4}{6}-\frac{5}{6})$
$-\frac{7}{8}a-\frac{1}{6}$

Therefore, the answer is $-\frac{7}{8}a-\frac{1}{6}$ . (Again, the first box is 7/8 and the second box is 1/6).

In reducing one's speed from 70 mph to 50 mph, how much of a percentage decrease in stopping distance is realized (to the neares

labwork [276]

we are given

we are given relation between speed and distance

distance ( when speed =70mph) is

=328feet

so, $d_1=328$

distance ( when speed =50mph) is

=183feet

so, $d_2=183$

now, we can find percentage in decrease

$=\frac{d_1-d_2}{d_1} \times 100$

now, we can plug values

$=\frac{328-183}{328} \times 100$

$=44$ %...........Answer

Y=4x-1<br>Y-2=x <br>i need help substitution method

Anton [14]

Answer:

x = 1, y = 3

Step-by-step explanation:

x = y - 2, so y = 4 (y - 2) -1

solve normally now

y = 4 (y - 2) -1

y = 4y - 8 - 1 (distribute)

y = 4y - 9 (simplify)

+9 -y -y +9

9 = 3y

3 = y

y - 2 = x

(3) - 2 = x

x = 1
