Answer:
50 cars and 25 bikes
Step-by-step explanation:
Given
Total wheels = 250
Required:
Number of cars and bikes
Let C represent Cars and B represents Bike
A car has 4 wheels and a bike has 2 wheels;
So,
Divide through by 2
---- Equation 1
The ratio of wheels of cars to wheels of bike is 1:2
Meaning that
1C = 2B
So, C = 2B
Substitute 2B for C in equation 1
Divide both sides by 5
Recall that C = 2B
So,
Hence, Anna has seen 50 cars and 25 bikes
Answer:
The answer is 4th point
Step-by-step explanation:
c∝b
c = k(b)
Let c = 3
b = 1
3 = k(1)
k = 3
c = 3b
Try:
Let c = 12
12 = 3b
b = 4 (proven)
We can divide 18 pounds by 2/3 pounds to find how many servings of meals the dogs will have.
We will use the keep change flip rule to solve this.
18 / 2/3 is then the same as 18 x 3/2
We then multiply across to get
54/2
This would be 27 meals that the food will last
Answer:
A. 25, obtuse
Step-by-step explanation:
By exterior angle theorem:
2x° = 30° + 20°
2x° = 50°
x° = 50°/2
x° = 25°
x = 25
Type of triangle: Obtuse
Step-by-step explanation:
210÷3×2=140 (140)CD
210-140=70 (70)left
70÷4×1=17.50 (17.50)food
70-17.50=52.50 (52.50)left
