Every hour at 12km/h I would go 12km. Simple.

The distance traveled in km is equal to 12 times how many hours you go.

If I go 27 km, I can go in reverse and divide by 12 to get 2.25 hours.

A quarter of an hour is 15 minutes, so the answer would be 2 hours and 15 minutes.

Equation that represents the line that passes through the point (-2,-1) and has a slope of 5
ss7ja [257]
Straight line:
y = mx + c
m is the slope of the graph and c is the y-intercept
In this case, m = 5 as stated in the question, so...
y = 5x + c
By substituting the given co-ordinates (-2,-1) into this equation, we can find c
-1 = 5(-2) + c
-1 = -10 + c
-1 + 10 = -10 + c + 10 (Add 10 to both sides)
9 = c
c = 9
Put c = 9 into the equation:
y = 5x + 9

Fill in the box with the appropriate measure.<br> quick please I have only a few min left
Art [367]

Step-by-step explanation:

first box on the left

r=4

d=8

circumference= 2π*4= 8π

area = π*4*4= 16π

Second box on the left

d=6

r= 3

circumference= 2π*3= 6π

area =π*3*3= 9π

third box on the left

A=36π

A=36πarea= π*r*r

A=36πarea= π*r*rr= 6

A=36πarea= π*r*rr= 6d=12

A=36πarea= π*r*rr= 6d=12circumference= 2π*6= 12 π

the last box

C=18π

C=18πC= 2π*r

C=18πC= 2π*rr= 9

C=18πC= 2π*rr= 9d=18

C=18πC= 2π*rr= 9d=18area= π*9*9= 81π

Giselle made 24 1/8 ounces of lemonade. She sampled 1 1/2 ounces to make sure it is not too sour. How much lemonade is left? Exp
vivado [14]

step.1 turn both of the numbers into fraction

24x8=192, because 8 out of 8 is 1. Plus one equals to 193/8

1x2=2 plus 1 equals to 3. 3/2

step.2 turn the bottom numver the same

because 2x4 is 8 from the bottom

3x4 is 12 so the lemonade she sampled is 12/8

step.3 substract

193/8-12/8you keep the bottom the same substract the top.

193-12

the answer is : 181/8
