Answer:

The answer for the step 5 is 52

Step-by-step explanation:

This is because, when a negative number multiply a negative number, it gives a positive answer

 thus ; - × - =+

so from the expression

16-36(-1)

 the negative 36 multiply the negative 1 to give positive 36

.

so the relation then become

16+36= 52

A taxi company charges passengers $2.00 for a ride, no matter how long the ride is, and an additional $0.20 for each mile travel

tiny-mole [99]

The answer will be $2.20. Because they only traveled one mile, which is 20 cents. Also the original cost before they even started driving was $2.00.

Create 2 lines thatare parallel to 8x + 2y = 7?

Alinara [238K]

d1 = ax + by + c = 0 and d2= mx + ky + f = 0

if they are parallel :

$\frac{a}{m} = \frac{b}{k} \neq \frac{c}{f}$

8x + 2y = 7

8x + 2y - 7 = 0

8x + 2y -9 = 0
4x + y -6 = 0
16x + 4y - 19 = 0

you can create more whatever you want =)

Hope this helps ^-^

To travel 80 miles, it takes Sue, riding a moped, 2 hours less time than it takes Doreen to travel 60 miles riding a bicycle. Su

andriy [413]

Answer:

Time taken by Doreen is 6 hours and speed is 10 miles per hour.

Time taken by Sue is 4 hours and speed is 20 miles per hour.

Step-by-step explanation:

Let the speed of Doreen be x

According to the question speed of Sue is = x+10

time taken By Sue to cover 80 miles = $\frac{80}{x+10}$

time taken by Doreen to travel 60 miles = $\frac{60}{x}$

According to question Sue take two hours less than Doreen takes

therefore

$\frac{60}{x}$ - $\frac{80}{x+10}$ =2

$\frac{60(x+10)-80x}{x(x+10)}$ =2

60(x+10) -80x = 2(x(x+10)

60x+600-80x = $2x^2+20x\\$

simplifying it ,we get

$2x^2+40x-600=0\\$

Dividing both sides by 2 ,we get

$x^2+20x-300=0\\$

solving it for x ,we get

(x+30)(x-10) =0

x =-30 which is not possible

x =10 miles per hour

Speed of Doreen = 10 miles per hour

Speed of Sue = 10+10 = 20 miles per hour

Time taken by Doreen = 60 divided by 10 = 6 hours

Time taken by Sue = 80 divided by 20 = 4 hours
