Answer:
Step-by-step explanation:
C
Answer: 36
Step-by-step explanation:
From the question, we are informed that for every 4 silver cars that are sold, 6 red cards are also sold.
When there are 90 cars sold in a month, the number of silver cars that were sold would be:
= [4 / (4 + 6)] × 90
= 4/10 × 90
= 4 × 9
= 36 silver cars
Answer: x = 109/48
Step-by-step explanation:
1. Simplify 4 x x/5 to 4x/5
1/4 + 4x/5 = 31 15
2. Subtract 1/4 from both sides
4x/5 = 31/15 - 1/4
3. Simplify 31/15 - 1/4 to 109/60
4x/5 = 109/60
4. Multiply 1both sides by 5
4x = 109/60 x 5
5. Simplify 109/60 x 5 to 545/60
4x = 545/60
6. Simplify 545/60 to 109/12
4x = 109/12
7. Divide both sides by 4
x = 109/12/4
8. Simplify 109/12/4 to 109/12 x 4
9. Simplify 12 x 4 to 48
x = 109/48
Hope this helps & happy halloween! :)
