Answer:

Step-by-step explanation:

PEMDAS stands for, "Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction."

PEMDAS is the order of operations so we multiply/divide before we add/subtract.

8 x 4 = 32

12 + 24 = 36

36 + 32 = 68

Vi walks five days each week.She walks the same distance on the first two days.On days three and four,Vi walks twice as long as

Alinara [238K]

Vi walks 2 miles on first day, 2 miles on second day, 8 miles on third and fourth day and 1 mile on fifth day.

Step-by-step explanation:

Let,

x be the distance walked by Vi.

Therefore,

On first day = x

Second day = x

On days three and four,Vi walks twice as long as on the first two days

Third and fourth day = 2(x+x) = 2(2x) = 4x

On fifth day = half of first day = $\frac{1}{2}x$ = 0.5x

Total distance = 13 miles

Therefore,

$x+x+4x+0.5x =13\\6.5x=13$

Dividing both sides by 6.5

$\frac{6.5x}{6.5}=\frac{13}{6.5}\\x=2$

Distance on first day = x = 2 miles

second day = x = 2 miles

third and fourth day = 4x = 4(2) = 8 miles

fifth day = 0.5x = 0.5(2) = 1 miles

Vi walks 2 miles on first day, 2 miles on second day, 8 miles on third and fourth day and 1 mile on fifth day.

Write the equation of the line perpendicular to 2x-3y=12 which passes through the point (16,-7).

Elanso [62]

Y= mx+b

(16, -7) = (x,y)

2(16) - 3y = 12
32 - 3y = 12
32 - 12 = 3y
20/3 = y
6.6 = y

2x-3(-7) = 12
2x+21 = 12
2x = 12 - 21
x = -9/2

Insert the values into y = mx + b
solve for m and then solve for b
