Answer:
<h2>only x = 39</h2>
Step-by-step explanation:
x + 6 = 45 <em>subtract 6 from both sides</em>
x + 6 - 6 = 45 - 6
x = 39

Answer:
Midpoint of side EF would be (-.5,4.5)
Step-by-step explanation:
We know that the coordinates of a mid-point C(e,f) of a line segment AB with vertices A(a,b) and B(c,d) is given by:
e=a+c/2,f=b+d/2
Here we have to find the mid-point of side EF.
E(-2,3) i.e. (a,b)=(2,3)
and F(1,6) i.e. (c,d)=(1,6)
Hence, the coordinate of midpoint of EF is:
e=-2+1/2, f=3+6/2
e=-1/2, f=9/2
e=.5, f=4.5
SO, the mid-point would be (-0.5,4.5)
Answer:
-5/9
Step-by-step explanation:
9(x+1)=4-2(9x+5)
Distribute
9x+9=4-18x-10
Add 4 and -10
9x+9=-6-18x
Move -18 to the left side and change sign
9x+9+18x=-6
Move 9 over and change sign
9x+18x=-6-9
Combine like terms
27x=-15
Divide both sides by 27
X=-5/9
Answer:
12 cm = 21.62 miles
6 cm = 11.04 miles
Step-by-step explanation:
To find the distance, set up a proportion. A proportion is two equal ratios set equal to each other. We form the ratios by using corresponding values. We write a ratio of 
and simplify.
We know 
. We know the distance on the map is 12 cm and 6 cm whish converts to 4.7 inches and 2.4 inches. We can write 
and 
We set them equal.
and
To solve each proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
and
