Answer:
50
Step-by-step explanation:
30 + 100 = 130
130 + 50 = 180
all triangles are 180 degrees, so add it up and subtract.
It is asking for the specific coordinates of the point (ex: (-3,5)).
.15x= .10x+10
-.10x=-.10x
.05x=10
Divide by 10
X=200
Answer is more than 200
So 201 or more

Answer:
5/9
Step-by-step explanation:
Let's define:
The following three equations are established from the question:
sw + j + sk = 120
sw/j = 8/3
j/sk = 3/4 or sk/j = 4/3
Dividing the first equation by j, we get:
sw/j + j/j + sk/j = 120/j
8/3 + 1 + 4/3 = 120/j
5 = 120/j
j = 120/5 = 24
sw = 24*8/3 = 64
sk = 24*4/3 = 32
After the replacement the new number of jeans and skirts are:
j' = 24 - 4 = 20
sk' = 32 + 4 = 36
the new ratio of jeans to skirts is:
j'/sk' = 20/36 = 5/9
