Answer:
if by decomposition you mean breaking it into parts then
break it into 2 triangles and 1 rectangle
left to right
triangle with base y and height h
h=10
y=3
area of triangle=1/2bh
area=1/2(10)(3)
area=5(3)
area=15
rectangle of length x and height h
area= length times width
x=8
h=10
area=8 times 10
aera=80
last triangle
should be same as other since same base (y) and same height (h)
15
add
15+80+15=120
Step-by-step explanation:
It is ten times bigger than the other
Answer:
The answer is 9(x-3).
Step-by-step explanation:
When adding/subtracting fractions you need a common denominator, but you already have one, which is x-3. So in general:
a/c-b/c=(a-b)/c so you just have:
(2x-6)/(x-3) now if you factor 2 from the numerator
2(x-3)/(x-3) the (x-3)s cancel out leaving
2
However! Note that division by zero is undefined, so x cannot equal 3. (because both original fractions had denominators of x-3)
What this all means is that that expression will equal 2 for all real values of x other than 3.
Answer:
5/6 miles
Step-by-step explanation:
Matthews travels 2.5 miles → this is 3 times the distance that Jennifer travels
Jennifer travels 2.5 / 3 miles = 5/6 miles
because,
2.5 = 2 and 1/2 = 5/2
(5/2) ÷ 3 = (5/2) *(1/3) = 5*1/ 2*3 = 5/6
