X and y are books
x is fiction
y=nonifiction
x+y=36
x=12+y
12+y+y=26
2y+12=26
minus 12
2y=14
divide 2
y=7
sub
x=12+y
x=12+7
x=19
nonfiction=7
Answer:
(5/2,5)
Step-by-step explanation:
The picture is a bit blurry but the perimeter of a shape is the lengths added.
(4a - 2b) + (7a + 3) + (9a - 4) = perimeter, I added the sides together
Combine like terms to get:
4a + 7a + 9a = 20a
-2b is left along becuase there are no other like terms
3 - 4 = -1
The perimeter is 20a - 2b - 1
Answer:
The option d
Step-by-step explanation:
find the intersection with x and y

https://tex.z-dn.net/?f=0%2By%3D-9%20%5Clongrightarrow%20y%3D-9%0A
and https://tex.z-dn.net/?f=y%3D0%0A
https://tex.z-dn.net/?f=x%2B0%3D-9
we get the coordinates
https://tex.z-dn.net/?f=(0%2C-9)%2C%20(-9%2C0)
and the same process for another equation

and these coordinates are those expressed in the d graph
Answer:
9.2 yd
Step-by-step explanation:
Given,
hypotenuse(h)=10 yd
base(b)=4yd
perpendicular(p)=?
we have Pythagoras Theorem
h²=p²+b²
p²=h²-b²
p=(h²‐b²)½
=(10²-4²)½
=(100-16)½
=(84)½
=9.2
