Answer: There are  62 tricycles in the shop.

Step-by-step explanation:

Given: Number of wheels in a bicycle = 2

Number of wheels in a tricycle = 3

Let x = Number of bicycles , y = Number of tricycles.

As per given , we have

x+y =120       (i)

2x+3y=302       (ii)

Multiplying 2 on both sides of (i)

2x+2y=240      (iii)

Subtract (iii) from (ii) , we get

y= 62

Put value of y in (i) , we get

x+62=120\\\\\Rightarrow\ x=120-62\\\\\Rightarrow\ x= 58

Hence, there are 58 bicycles and 62 tricycles in the shop.

Determine if the equations are parallel, perpendicular, or neither.
Aloiza [94]
To easily find the slope from standard form (Ax + By = C) use -A/B

1. m = -5/3
2. m = -3/5

perpendicular slopes are negative reciprocals, which these are not

parallel slopes are exactly the same, which these are also not

so, these equations are neither parallel nor perpendicular

ArbitrLikvidat [17]

Answer:

32.9 inches

Step-by-step explanation:

this can be solved using Pythagoras theorem

The Pythagoras theorem : a² + b² = c²

where a = length

b = base = 49

c =  hypotenuse = diagonal = 59

l² + 49² = 59²

l² = 59² - 49²

3481 - 2401 = 1080

find the square root
