Point J is the midpoint of segment FG with endpoints F(1,4) and G(5,12). Point K is the midpoint of segment GH with endpoints G(
faltersainse [42]

Answer:

1 unit

Step-by-step explanation:

If point J is the midpoint of segment FG with endpoints F(1,4) and G(5,12), then its coordinates are

x_J=\dfrac{x_F+x_G}{2}=\dfrac{1+5}{2}=3\\ \\y_J=\dfrac{y_F+y_G}{2}=\dfrac{4+12}{2}=8

If point K is the midpoint of segment GH with endpoints G(5,12) and H(-1,4), then its coordinates are

x_K=\dfrac{x_G+x_H}{2}=\dfrac{5+(-1)}{2}=2\\ \\y_K=\dfrac{y_G+y_H}{2}=\dfrac{12+4}{2}=8

The measure of JK is

JK=\sqrt{(3-2)^2+(8-8)^2}=\sqrt{1^2+0^2}=1\ unit

11 more than y is equal to 7
fomenos

We first have to come up with an equation that satisfies this. The equation is y+11=7.

Then we subtract 11 from both sides. y+11-11=7-11.

Then we get the answer y=-4.

Make w the subject of <br> Y-aw=2w-1
Luda [366]
So you're gonna take add 1 to both sides and add aw to both sides also
y+1=2w+aw
then you factorize the w
y+1=w(2+a)
divide 2+a in both sides
y+1/2+a=w
the answer is
y+1/2+a=w

75

Step-by-step explanation:

We know that 80% of Andrew's (former) baseball card collection is 60. Thus, We divide 60 by 80% (equal to 0.8) to obtain \frac{60}{0.8}=75.
