Cost of airplane toy = $4.84
let x be the cost of the toy car
cost of airplane toy is 4 times the cost of toy car; it means
4x = $4.84
x = 4.84 / 4
x = 1.21
Thus, the cost of toy car is $1.21.
Answer:
19y+5
Step-by-step explanation:
Combine like terms look for all the numbers that have y attached and combine them
7y +12y=19y
Look for terms where nothing is attached it's just the number combine them
6-1=5
Put all together again and you get:
19y+5
Answer:
5/2
Step-by-step explanation:
Convert both fractions into improper fractions:
- To convert these fractions into an improper fraction you need to multiple the denominator with the mixed numeral/whole number. Then add that amount to the numerator. Do this for both fractions. This is what it should look like.
38/6 - 23/6.
The you subtract it
- 38/6 - 23/6 = 15/6
15/6 is your answer
If you want to simplify it the fraction it will be :
- 5/2
Answer:
52 young calves
Step-by-step explanation:
At a dairy farm the ratio of adult milking cows to young calves was 9:2. If there were 234 adult milking cows at the farm, how many young calves were there?
The ration is given as:
adult milking cows to young calves
= 9 : 2
= 234 : x
= 9/2 = 234/x
x = Number of young calves
Cross Multiply
9 × x = 2 × 234
= x = 2 × 234/9
x = 468/9
x = 52
Hence, the number of young calves on the farm is 52.
