Mathematics
1 answer:
miskamm [114]4 years ago
6 0

Answer:

k=-9

Step-by-step explanation:

Given equation is

3k-5=(k+4)+3k

3k-5=k+4+3k

Adding -3k on both sides of equation we get

3k-5-3k=k+4+3k-3k

We know that 3k-3k=0

-5=k+4

Adding -4 on both side of above equation, we get

-5-4=k+4-4

-9=k

k=-9 which is the answer.

AVprozaik [17]

Answer:

12 minutes

Step-by-step explanation:

 <u>50 miles</u>      =    <u>10 miles</u>                  << Equivalent

   1 hour        =          x                        <<   fraction

You divide 50 by 5 to get 10,

so to get the number of minutes for 10 miles,

divide 60 by 5.

(1 hour =  60 minutes, 60/5 = 12)

What are the x- and y- coordinates of point E, which partitions the directed line segment from J to K into a ratio of 1:4?
Aleks [24]

The x- and y- coordinates of point E, which partitions the directed line segment from J to K into a ratio of 1:4 is (17, 11)

<h3>Midpoint of coordinate points</h3>

The midpoint of a line is the point that bisects or divides the line into two equal parts

If the line JK is partitioned into the ratio 1:4 with the following coordinates

J(-15, -5) and K(25, 15)

Using the expression below;

M(x, y) =[mx1+nx2/m+n, my1+ny2/m+n]

Substitute the ratio and the coordinates

M(x, y) =[1(-15)+4(25)/4+1, 1(-5)+4(15)/1+4]

M(x, y) = [(85)/5, 55/5]

M(x, y) = (17, 11)

Hence the x- and y- coordinates of point E, which partitions the directed line segment from J to K into a ratio of 1:4 is ((17, 11)
