Answer:
Its 1
Step-by-step explanation:
Answer:
v = 6/7 + 2/7y
Step-by-step explanation:
<u>Step 1: Distribute</u>
-7(-2v + 5) - 4y = 2(1 - 9) - 7
14v - 35 - 4y = 2 - 18 - 7
Step 2: Add 35 to both sides
14v - 35 + 35 - 4y = -23 + 35 + 4y
14v = 12 + 4y
Step 3: Divide both sides by 10
14v / 14 = 12 + 4y / 14
v = 6/7 + 2/7y
Answer: v = 6/7 + 2/7y
Answer:
This is mode defined
Step-by-step explanation:
Answer: there are eight bicycles and 7 tricycles.
Step-by-step explanation:
Let x represent the number of bicycles that are there.
Let y represent the number of tricycles that are there.
There are a total of 15 bicycles and tricycles. This means that
x + y = 15
A bicycle has 2 wheels and a tricycle has 3 wheels. There are 37 wheels all together if we count them up. This means that
2x + 3y = 37- - - - - - - - - - - - - 1
Substituting x = 15 - y into equation 1, it becomes
2(15 - y) + 3y = 37
30 - 2y + 3y = 37
- 2y + 3y = 37 - 30
y = 7
x = 15 - y = 15 - 7
x = 8
