Answer:
x = 9; y = 12; u = 24; v = 32
Step-by-step explanation:
The corresponding sides of similar triangles are in the same ratio to each other.
3/5 = (3 + x)/20 Multiply each side by 20
20×3/5 = 3 + x
12 = 3 + x Subtract 3 from each side
x = 9
=====
4/5 = (4 + y)/20 Multiply each side by 20
20×4/5 = 4 + y
16 = 4 + y Subtract 4 from each side
y = 12
=====
3/5 = (3 + x + u)/60 Multiply each side by 60
60×3/5 = 3 + x + u
36 = 3 + x + u Insert the value of x
36 = 3 + 9 + u
36 = 12 + u Subtract 12 from each side
u = 24
=====
4/5 = (4 + y + v)/60 Multiply each side by 60
60×4/5 = 4 + y + v
48 = 4 + y + v Insert the value of y
48 = 4 + 12 + v
48 = 16 + v Subtract 16 from each side
v = 32
x = 9; y = 12; u = 24; v = 32
Answer:
Step-by-step explanation:
given
45 = 25m + b ( isolate the term in m by subtracting b from both sides )
45 - b = 25m ← divide both sides by 25
= m
Y-7=-2(x+1)
Y-7=-2x-2
Y=-2x+5
In this question there is a simple trick that needs to be handled first. Baring that simple trick the problem is very easy. The first thing that needs to be done after noting down all the details from the given question is to covert 1 hour to 60 minutes.
Time taken by Carla to travel 5 miles = 1 hour
= ( 1 * 60 ) minutes
= 60 minutes
Then
In 60 minutes the distance covered by Carla = 5 miles.
NOw
In 15 minutes the distance traveled by Carla = (5/60) * 15 miles
= 5/4 miles
= 1.25 miles
So Carla will travel a distance of 1.25 miles in 15 minutes.
Answer:
therefore According to the diagram y= start over
