For #2, the proportion would be .40/.25 and x/15, then you would cross multiply to find x. and for #3 the proportion would be 15/6 and 75/x and again you would cross multiply to find x. (:
Answer:
Vertex: (4,9)
X int: (1,0),(7,0) = x=-1, x=-7
y iny: (0,-7)
Answer:
x= 25
Step-by-step explanation:
There are 180 degrees in a triangle
100 + 55 + x = 180
155 + x = 180
Subtract 155 from 180
x = 25
Combine like terms : 8y = 16
Divide by 8 on both sides : y = 2
Answer: 40%
Step-by-step explanation:
Let the percent be x , then
x 110 = 44
110x = 4400
x = 4400/110
x = 40
Therefore : 44 is 40 percent of 110
